Hello,

I am on Debian Jessie with a kernel from backports:
4.6.0-0.bpo.1-amd64

I am also using btrfs-tools 4.4.1-1.1~bpo8+1

When trying to replace a RAID1 drive (with btrfs replace start
-f /dev/sda1 /dev/sdd1), the operation is cancelled after completing
only 5%.

I got this error in the /var/log/syslog:
------------[ cut here ]------------

I don't often see handle_mm_fault with btrfs problems, maybe the
entire dmesg from mounting the fs and including btrfs replace would
reveal a related problem that instigates the failure?

If the device being replaced is acting unreliably, then you'd want to
use -r with replace to ignore that device unless it's absolutely
necessary to read from it.

Thanks for your help.

Ok here is the log from the mounting, and including btrfs replace

Eek. So sdb has 11+ million write errors, flush errors, read errors,
and over 1 million corruptions. It's dying or dead.

And sda has a dozen thousand+ corruptions. This isn't a good
combination, as you have two devices with problems and raid5 only
protects you from one device with problems.

You were in the process of replacing sda, which is good, but it may
not be enough...

Shoot. You have a lot of these. It looks suspiciously like you're
hitting a case list regulars are only just starting to understand
(somewhat) where it's possible to have a legit corrupt sector that
Btrfs detects during scrub as wrong, fixes it from parity, but then
occasionally wrongly overwrites the parity with bad parity. This
doesn't cause an immediately recognizable problem. But if the volume
becomes degraded later, Btrfs must use parity to reconstruct
on-the-fly and if it hits one of these bad parities, the
reconstruction is bad, and ends up causing lots of these checksum
errors. We can tell it's not metadata corruption because a.) there's a
file listed as being affected and b.) the file system doesn't fail and
go read only. But still it means those files are likely toast...

OK yeah so bad sector on sdb. So you have two failures because sda is
already giving you trouble while being replaced and on top of it you
now get a 2nd (partial) failure via bad sectors.

So rather urgently I think you need to copy things off this volume if
you don't already have a backup so you can save as much as possible.
Don't write to the drives. You might even consider 'mount -o
remount,ro' to avoid anything writing to the volume. Copy the most
important data first, triage time.

While that happens you can safely collect some more information:

btrfs fi us <mp>
smartctl -x <dev>   ## for both drives

Forget this part completely. It doesn't affect raid1. I just re-read
that your setup is not raid1, I don't know why I thought it was raid5.

The likely issue here is that you've got legit corruptions on sda (mix
of slow and flat out bad sectors), as well as a failing drive.

This is also safe to issue:

smartctl -l scterc /dev/sda
smartctl -l scterc /dev/sdb
cat /sys/block/sda/device/timeout
cat /sys/block/sdb/device/timeout

Ok thanks I will begin to make an image with dd.
Do you recommend to use sda or sdb ?

Well at the moment you're kinda stuck. I'd leave them together and
just get the data off the drive normally with cp -a (or just -r if you
don't care about permissions and other metadata like time stamps and
xattr) or rsync -a. Certainly the dying drive is being really pissy
but if you get a bad read off one drive *maybe* it can correct off the
other drive. But that's not possible if you pull one of those drives.

Also as for imaging the drive, you probably need to use ddrescue instead of dd.

Be warned that there's a gotcha where you can corrupt Btrfs volumes
where multiple instances of the same fs uuid and dev uuid appear at
the same time to the kernel. So once you've cloned in this manner,
don't mount the volume until you hide (as in remove) one of the
copies. See block level copies:

No current pending, reallocated, or uncorrected sectors. Interesting.
But this drive has piles of write errors. Why? Bad cable? That should
result in UDMA CRC errors, lots of them.

No significant problems.

One pending sector. Enough for a dozen scary warnings or so, but not
enough to account for as many as you have. Pretty curious.

Consistent.

Also consistent. For whatever reason it's not being overwritten... I
guess the copy on dev/sda is bad or unavailable.

The vendor specific ones have a massive pile of noise in them compared
to the other drive. But inconclusive because they aren't defined.

Good news and bad news. The bad news is this is a significant
misconfiguration, it's very common, and it means that any bad sectors
that don't result in read errors before 30 seconds will mean they
don't get fixed by Btrfs (or even mdadm or LVM raid). So they can
accumulate.

There are two options since your drives support SCT ERC.

1.
smartctl -l scterc,70,70 /dev/sdX  ## done for both drives

That will make sure the drive reports a read error in 7 seconds, well
under the kernel's command timer of 7 seconds. This is how your drives
should normally be configured for RAID usage.

2.
echo 180 > /sys/block/sda/device/timeout
echo 180 > /sys/block/sdb/device/timeout

This *might* actually work better in your case. If you permit the
drives to have really long error recovery, it might actually allow the
data to be returned to Btrfs and then it can start fixing problems.
Maybe. It's a long shot. And there will be upwards of 3 minute hangs.

I would give this a shot first. You can issue these commands safely at
any time, no umount is needed or anything like that. I would do this
even before using cp/rsync or ddrescue because it increases the chance
the drive can recover data from these bad sectors and fix the other
drive.

These settings are not persistent across a reboot unless you set a
udev rule or equivalent.

On one of my drives that supports SCT ERC it only accepts the smartctl
-l command to set the timeout once. I can't change it without power
cycling the drive or it just crashes (yay firmware bugs). Just FYI
it's possible to run into other weirdness.


Last, I have no idea if the massive Btrfs write errors on sda are from
an earlier problem where the drive data or power cable got jiggled or
was otherwise absent temporarily? So depending on how the block
timeout change affects your data recovery, you might end up needing to
do a reboot to get back to a more stable state for all of this? It
really should be able to fix things *if* at least one copy can be read
and then written to the other drive.

correction: "well under the kernel's command timer default of 30 seconds"

I've tried both option and launched a replace, but I got the same error
(replace is cancelled, jernel bug).
I will let these options on and attempt a ddrescue on /dev/sda
to /dev/sdd.
Then I will disconnect /dev/sda and reboot and see if it works better.

I have also no idea why is sda behaving like this. I haven't done
anything particular on these drives.

Thanks for your help !

Sounds reasonable. Just make sure the file system is already unmounted
when you use ddrescue because otherwise you're block copying it while
it could be modified while rw mounted (generation number tends to get
incremented while rw mounted).

Yeah pretty weird. At some point once things are stable, if this file
system survives, you might want to use btrfs dev stat -z to wipe out
those stats.

Well I made a ddrescue image of both drives (only one error on sdb
during ddrescue copy) and started the computer again (after
disconnecting the old drives).

However the errors remains there, and I still cannot scrub (scrub is
aborted), nor delete the file which have errors (drive is remounted
read-only if I try to delete the files).

I don't know if I should continue trying to repair this RAID1 or if I
should just cp/rsync to a new BTRFS volume and get done with it.
On the other hand it seems interesting to repair instead of just giving
up. It gives a good look at BTRFS resiliency/reliability.

Here is the log from the mount to the scrub aborting and the result
from smartctl.

Thanks for your precious help so far.

What was the error? Any kernel message at the time of this error?

Well for sure already you should prepare to lose this volume, so
whatever backup you need, do that yesterday.

On the one hand Btrfs shouldn't become inconsistent in the first
place, that's the design goal. On the other hand, I'm finding from the
problems reported on the list that Btrfs increasingly mounts at least
read only and allows getting data off, even when the file system isn't
fully functional or repairable.

In your case, once there are metadata problems even with raid 1, it's
difficult at best. But once you have the backup you could try some
other things once it's certain the hardware isn't adding to the
problems, which I'm still not yet certain of.

Not sure what this is. The Btrfs cleaner is used to remove snapshots,
decrement extent reference count, and if the count is 0, then free up
that space. So, why is it running? I don't know what -30 means.

I missed something the first time around in these messages: the
generation error. Both drives have generation errors. A generation
error on a single drive means that drive was not successfully being
written to or was missing. For it to happen on both drives is bad. If
it happens to just one drive, once it's reappears it will be passively
caught up to the other one as reads happen, but best practice for now
requires the user to run scrub or balance. If that doesn't happen and
a 2nd drive vanishes or has write errors that cause generation
mismatches, now both drives are simultaneously behind and ahead of
each other. Some commits went to one drive, some went to the other.
And right now Btrfs totally flips out and will irreparably get
corrupted.

So I have to ask if this volume was ever mounted degraded? If not you
really need to look at logs and find out why the drives weren't being
written to. sdb show lots of write, flush, corruption and generation
errors, so it seems like it was having a hardware issue. But then sda
has only corruptions and generation problems, as if it wasn't even
connected or powered on.

OR another possibility is one of the drives was previously cloned
(block copied), or snapshot via LVM and you ran into the block level
copies gotcha:

Some extent data and its checksum don't match, on sdb. So this file is
considered corrupt. Maybe the data is OK and the checksum is wrong?

And it can't be fixed, because...

The same block on sda also doesn't match checksum. So either both
checksums are wrong, or both datas are wrong.

You can make these errors "go away" by using btrfs check --repair
--init-csum-tree but what this does it it will totally paper over any
real corruptions. You will have no idea if they're really corrupt or
not without checking them. Looks like most of the messages have to do
with files, not metadata although I didn't look at every single line.

I think the generations between the two drives is too far off for them
to be put back together again. But if the --init-csum-tree starts to
clean up the data related errors, you could use rsync -c to compare
the files to a backup and see if they are the same and further inspect
to see if they're corrupt or not.

You definitely don't want corrupt files propagating into your future
backups. That's bad news.

ddrescue reported an error during operation ("error: 1" displayed).
Dump of /var/log/syslog during the ddrescue operation is appended at
the end of this email.

Already got a backup. I just really want to try to repair it (in order
to test BTRFS).

I'm ready to try anything. Let's experiment.

I got some errors on sdb 2 months ago (I noticed it because it was
suddenly mounted read-only). I ran a scrub and a check --repair, and
a lot of errors were corrected. I deleted the files which were not
repairable and everything was running smoothly since. I ran a scrub a
few weeks ago and everything was fine.

I never mounted in degraded mode or made a snapshot via LVM (I only

All these files are expendables (it seems to be files which were
written only recently). So I can safely delete them if necessary.

So if I understand correctly, you advise to use check --repair
--init-csum-tree and delete the files which were reported as having
checksum error ?
After that I can compare the important files to a backup, but there is
always the non-important files which are not backuped.

Is there anyway I can be sure afterwards that the volume is indeed
completely correct and reliable ?
If there is no way to be sure, I think it is better that I cp/rsync all
data to a new BTRFS volume.

Thanks for yout help !

I don't know that this is a good test because I think the file system
has already been sufficient corrupted that it can't be fixed. Part of
the problem is that Btrfs isn't aware of faulty drives like mdadm or
lvm yet, so it looks like it'll try to write to all devices and it's
possible for significant confusion to happen if they're each getting
different generation writes. Significant as in, currently beyond
repair.

I kinda think it's a waste of time. Someone else maybe has a better idea?

I think your time is better spent finding out when and why the device
with all of these write errors happened. It must have gone missing for
a while, and you need to find out why that happened and prevent it; OR
you have to be really vigilent at every mount time to make sure both
devices have the same transid (generation). In my case when I tried to
sabotage this, being of by a generation of 1 wasn't a problem for
Btrfs to automatically fix up but I suspect it was only a generation
mismatch in the superblock.

I'm not sure what to tell you. Maybe look at logs for the last three
weeks for Btrfs and libata related messages to see if something else
happened since that good scrub that you didn't notice. Also look at
the mount messages and see if there are incrementing error counts in
messages like this >

BTRFS info (device sdb1): bdev /dev/sdb1 errs: wr 11881695, rd 14,
flush 7928, corrupt 1714507, gen 1335

Maybe you can ignore corrupt value because once there are checksum
problems that number increments everytime the same corruption is
found, it looks like. But if in the week after the scrub these numbers
are changing there is a hardware problem somewhere and you need to
find it. Btrfs can't be expected to work around every possible
hardware problem.

Yes but all this does is mask the problem with the files. It might
clean up the error messages do you can find out if the file system
itself is bad, including making btrfs check more legible for file
system problems rather than file extent corruption.

Unknown. In theory if it passes scrub and btrfs check and mounts read
write then it's a good file system. But there are bugs so it's
possible it comes up healthy but then in a week or month, *shrug*,
it's a test.

I personally would probably just obliterate it and start over, *and*
also be more vigilant at mount time about generation numbers, and also
check the logs periodically for device problems.

This one *especially* is not good:

This is a hung read command. The drive hasn't responded within the
time set in /sys/block/sdX/device/timeout and like I mentioned in a
previous message that's 30 seconds by default. When recovering from a
bad or unknown state it's probably better to set this to 180 for each
drive. In normal usage, it's better to set the SCT ERC for each drive
to 70 deciseconds so errors happens faster and Btrfs can fix it
sooner.

Reset means we don't really know what went wrong.

This is semi-bad in that it means there's a sector that can't be read.
Its data is lost. Btrfs has to use a mirror copy but if that mirror
copy is corrupt / doesn't mass checksum, then Btrfs will not do a
fixup and you're stuck. It's good in that there's an explicit read
error due to media defect and the drive supplied the LBA that's
affected. Some of these are OK as long as they're being fixed through
redundancy.

Oh and I forgot to add that rsync doesn't support reflink yet, so I am
bit reluctant to rsync all data to a new volume instead of repairing
the existing BTRFS volume.

Ok I will follow your advice and start over with a fresh BTRFS volume.
As explained on another email, rsync doesn't support reflink, so do you
think it is worth trying with BTRFS send instead ?
Is it safe to copy this way or rsync is more reliable in case of faulty
BTRFS volume ?

Many thanks !

If you have the space, btrfs restore would probably be the best option. 
It's not likely, but using send has a risk of contaminating the new 
filesystem as well.

I have to copy through the network (I am running out of disks...) so
btrfs restore is unfortunately not an option.
I didn't know that btrfs send could contaminate the target disk as
well ?
Ok rsync it is then.

Thanks

restore will let you extract files despite csum errors. I don't think
send will, and using cp or rsync Btrfs definitely won't hand over the
file.

That's Ok I'd prefer to avoid copying files with csum errors anyway (I
can restore them from backups).
However will btrfs send abort the whole operation as soon as it finds a
csum error ?
And will I have the risk to "contaminate" the target BTRFS volume by
using BTRFS send ?

Thanks !

   A send stream is effectively just a sequence of filesystem commands
(mv, cp, cp --reflink, rm, dd). So any damage that it can do when
replayed by receive is limited to what you can do with the basic shell
commands (plus cloning extents). If you have metadata breakage in your
source filesystem, this won't cause the same metadata breakage to show
up in the target filesystem.

Well after 300GB copied through "btrfs send", the process is aborted
with the following error:
ERROR: send ioctl failed with -5: Input/output error
ERROR: unexpected EOF in stream.

/var/log/syslog relevant lines are appended at the end of this email.

So it seems that I will have to go with rsync then.

By default yes, but it's the receive side that aborts. So you use
--max-errors 0 to let it tolerate unlimited errors, and use -v for
both send and receive to track what errors there are.

No.

You'll likely hit the same bad file and get EIO, is my guess. What you
can do is mount it ro from the get go, and do btrfs send receive again
and maybe then it won't hit this sequence where it's finding some need
to clean up a transaction and free an extent. Maybe you still get some
failure to send whatever file is using that extent, but I think
receive will tolerate it.

Well I tried "btrfs send" and the process stalled at 300 GB (on a total
of 2 TB) with a never ending stream of:
"ERROR: unexpected EOF in stream."
I gave up and launched a rsync which is about to be finished.

Now I have some work to make sure that all rsynced files are consistent
(I have to compared them to the backuped ones).

Thanks for your help, I learned a bit more about BTRFS this way.
