Hi,
I have a raid10-like setup that is failing to mount in rw mode with the error
mount: /mnt/media: wrong fs type, bad option, bad superblock on
/dev/mapper/em1, missing codepage or helper program, or other error
read-only mounts seem to work and the files seem to be there.
I started having issues after a system crash during the process of
deleting a number of large files. After this (Ubuntu 16.04/Kernel
4.4), any attempt to mount the array in rw mode would cause a similar
crash. I did an upgrade to Ubuntu 18.04/Kernel 4.15 and now get the
error above.
I have looked through a variety of posts on the mailing list, but
couldn't find anything with the same issue. I have done a scrub on the
array that resulted in 6 verify errors with dmesg showing something
about extent trees. It didn't list them as uncorrectable errors, but
couldn't correct them either as I can't mount in rw. I also tried
`btrfs rescue zero-log /dev/mapper/em1`, which changes the above to
(say) em5, but then zero-log on em5 causes it to go back to em1.
Any direction would be appreciated. From what I could tell, my next
steps would be a check with --repair or --init-extent-tree, though I'm
reluctant to try those without being explicitly told to do so.
I have attached a dmesg.log file and hope I haven't greped out
anything important.
Thanks,
Daniel

So you zero'd the log? Why? You need to slow down and stop making
changes to your file system unless you hate your data and want to lose
it. The log is there to help protect your data, you don't zero the log
except under very specific situations, none of which appear to apply
to your situation.
'btrfs check' is safe, --repair may or may not be safe, you didn't say
what version of btrfs-progs you're using, I would consider 4.14.1 at
the oldest, it should be straightforward with any distro to get
something relatively new, maybe from a testing repo. Current is 4.16.
And good god don't use --init-extent-tree, that's a hammer. The
absolute safest way to troubleshoot Btrfs problems is using newer
kernel versions, even though 4.15 is not old, there are still tons of
bug fixes in every release.
Suspicious items from your dmesg:
[95639.492347] BTRFS error (device dm-11): pending csums is 44810240
[95639.492791] BTRFS error (device dm-11): cleaner transaction attach

OK so it's a multiple device Btrfs volume, and you have one device
missing a metric done of reads and writes and flushes, with a few
corruptions and generation mismatches. What's wrong with
/dev/mapper/em5? Have you done any troubleshooting to figure out what
that problem is? Because Btrfs can't fix it, and it can't make up for
it. That looks like the device was missing for a long time, and writes
were only going to em3. So what's the backstory?
Your very first task right now is to mount ro, and update your
backups. Don't do anything else until you've done that. It's a
testimony to Btrfs that this file system mounts at all, even ro, so
take advantage of this fact before you can't mount it anymore.

After you've done the backup, you need to find out why one of these
devices is being so unreliable. That has to be fixed first. You can
recreate a new Btrfs or some other file system, and you'll just run
into the exact same problem down the road. Next, it might be useful to
see the output from btrfs-progs 4.16.1 'btrfs check' and 'btrfs check
--mode=lowmem' both of which are slow, the second one is really slow
but is a different implementation so it's helpful to see both outputs.
That's safe as long as you do not use --repair.
Also we need to see the output from 'btrfs fi us <mountpoint>' with
the volume mounted (ro). Off hand I think the most likely outcome is
that you get a backup from the ro mounted file system, and you'll have
to recreate it from scratch and restore from backups. In other words,
no matter what you need a current backup.

The problem is, your extent tree is corrupted.
And normally, it indicates your whole filesystem has more or less extra
errors.
In this case, btrfs check could help you to know how badly your fs is
corrupted.
(don't run --repair).
Optionally, btrfs check --mode=lowmem is pretty a good try, as it would
provide better error message.
(And help us enhance btrfs-progs)

Never run this two, unless you're 100% sure about:
1) What's the problem
2) What --repair can fix
Personally speaking, and also stated in man page, unless you're a
btrfs-progs developer or has enough experience, don't do any write
operation with btrfs check.

Backups are in place for the important parts, though I'd prefer not to
use them if possible.
For btrfs-progs, I am using 4.16.1 installed from
https://github.com/kdave/btrfs-progs.
Regarding em5, it had errors when I initially added it to the array
that were due to a faulty SAS card. The card was replaced and I
haven't seen errors since until this popped up. Regarding what you
said about my dmesg, the numbers are actually still the same (bdev
/dev/mapper/em5 errs: wr 164286, rd 3444262, flush 2110, corrupt 3,
gen 181) after doing a backup and reboot. I would think they would
have changed unless btrfs is just ignoring that disk now. Just to make
sure, I've checked to make sure there weren't any loose connections.
The logs for check (with and without lowmem mode), `btrfs fi us`, and
`smartctl -x` are attached. The checks are only for em5, but I can do
other disks if necessary (it's a 6-disk raid10-style setup). Note that
there are a lot of errors on the SMART info, but they seem to be back
from when I was having hardware issues.

From the output, specially the lowmem mode output since original mode
handles extent tree corruption poorly and aborted, it's your extent tree
corrupted and causing the bug.
Thus, you should be able to mount the fs RO and copy all the data back
without much hassle.
Just need to pay attention for csum error.
And considering how many extent tree corruption, I don't think it's a
good idea to manually fix the fs.
The last chance is, to try --repair --init-extent-tree as your last
chance, if you still want to salvage the filesystem.
The lowmem mode shows no extra bug, thus it's possible for
--init-extent-tree to re-init extent tree and save the day.
But personally speaking I'm not fully confident of the operation, thus
it may fail and you may need to use the backup.
BTW, even --init-extent-tree succeeded, you may still need to run btrfs
check again to check if all the bugs are fixed.
But at least from the lowmem output, the remaining errors are all fixable.
Thanks,
Qu

Thanks for the help, I started `check --repair --init-extent-tree`
right around a week ago as a last effort before restoring from backup.
Unfortunately, that command is still running. It does seem to be using
about half of the system's RAM (8 of 16GB) and 100% load on a single
core. Is this type of run time expected for an 8TB drive? The byte
numbers it's referencing seem to be a bit odd to me as they're larger
than the number of bytes on the drive. Here's the head and tail of the
current run (separated by -----) if that's indicative of progress:

It depends.
Since it will iterate the whole disk serval times, it takes a long time,
especially if you have a lot of used space of that 8T drive.
To determine if it's doing dead loop, we need to verify the output is
not duplicating itself.

Completely valid.
As btrfs is using logical address, it's completely valid that logical
bytenr is larger than your device if you have balanced the device
several times before.

Looks it's processing.
But it's better to keep all the output and verify the same section of
bytenr doesn't re-appear too many times.
