This is an interesting one -- the invariant that assert is checking
isn't too complicated (that the object lives on the RecoveryWQ's
queue) and seems to hold everywhere the RecoveryWQ is called. And the
functions modifying the queue are always called under the workqueue
lock, and do maintenance if the xlist::item is on a different list.
Which makes me think that the problem must be from conflating the
RecoveryWQ lock and the PG lock in the few places that modify the
PG::recovery_item directly, rather than via RecoveryWQ functions.
Anybody more familiar than me with this have ideas?
Fyodor, based on the time stamps and output you've given us, I assume
you don't have more detailed logs?

Greg, i got this crash again.
Let me tell you the configuration and what is happening:
Configuration:
6 osd servers. 4G RAM, 4*1T hdd (mdadmed to raid0), 2*1G etherchannel
ethernet, Ubuntu server 11.04/64 with kernel 2.6.39 (hand compiled)
mon+mds server 24G RAM, the same os.
On each OSD Journal placed on 1G tempfs. OSD data - on xfs in this case.
Configuration file:
[global]
max open files = 131072
log file = /var/log/ceph/$name.log
pid file = /var/run/ceph/$name.pid
[mon]
mon data = /mfs/mon$id
[mon.0]
mon addr = 10.5.51.230:6789
[mds]
keyring = /mfs/mds/keyring.$name
[mds.0]
host = mds0
[osd]
osd data = /$name
osd journal = /journal/$name
osd journal size = 950
journal dio = false
[osd.0]
host = osd0
cluster addr = 10.5.51.10
public addr = 10.5.51.140
[osd.1]
host = osd1
cluster addr = 10.5.51.11
public addr = 10.5.51.141
[osd.2]
host = osd2
cluster addr = 10.5.51.12
public addr = 10.5.51.142
[osd.3]
host = osd3
cluster addr = 10.5.51.13
public addr = 10.5.51.143
[osd.4]
host = osd4
cluster addr = 10.5.51.14
public addr = 10.5.51.144
[osd.5]
host = osd5
cluster addr = 10.5.51.15
public addr = 10.5.51.145
What happening:
osd2 was crashed, rebooted, osd data and journal created from scratch by
"cosd --mkfs -i 2 --monmap /tmp/monmap" and server started.
Additional - on osd2 enables "writeahaed", but I think it's not
principal in this case.
Well, server start rebalancing:

I.e. it's not "easy reproduced" bug. While I had less data in the
cluster - I not seen this error.
I think that I do not have enough space for "full" log for 2-3 hours. Sorry.

Fyodor.

Okay, one of us should have a patch for you later today to try out;
the only cause I can come up with seems unlikely but there aren't many
options so it should be pretty simple. :)
I opened a tracker issue for it: http://tracker.newdream.net/issues/1116

Can you check out the recoverywq_fix branch and see if that prevents
this issue? Or just apply the patch I've included below. :)

Hi,
two of my osds on different nodes do not start. Now I have one pg
that is down. This happened on ceph version 14.2.10 and still happens
after upgrading to 14.2.11. I get this error when starting osd:

I had one of my OSDs crash yesterday. I'm using ceph version 0.56.3 (6eb7e15a4783b122e9b0c85ea9ba064145958aa5).
The part of the log file where the crash happened is attached. Not really sure what lead up to it, but I did get an alert from my server monitor telling me my swap space got really low around the time it crashed.
The OSD reconnected after restarting the service. Currently, I'm waiting patiently as 1 of my 400 pgs gets out of active+clean+scrubbing status.

Can you install debug symbols to see what line number this is one (e.g.
apt-get install ceph-dbg), or check in the log file to see what the assert
failure is?
Thanks!

Hi,
Almost always one or more osd dies when doing overlapped recovery -
e.g. add new crushmap and remove some newly added osds from cluster
some minutes later during remap or inject two slightly different
crushmaps after a short time(surely preserving at least one of
replicas online). Seems that osd dying on excessive amount of
operations in queue because under normal test, e.g. rados, iowait does
not break one percent barrier but during recovery it may raise up to
ten percents(2108 w/ cache, splitted disks as R0 each).

This looks very similar to something we hit last week. The fix is still
pending (wip_recovery_complete). Do you have the last few lines of the
log, that include the failed assertion message?

Thanks! I didn`t measured a # of connection because of bearing in mind
1 conn per client, raising limit did the thing. Previously mentioned
qemu-kvm zombie does not related to rbd itself - it can be created by
destroying libvirt domain which is in saving state or vice-versa, so
I`ll put a workaround on this. Right now I am faced different problem
- osds dying silently, e.g. not leaving a core, I`ll check logs on the
next testing phase.

The tcmalloc backtrace on the OSD suggests this may be unrelated, but
what's the fd limit on your monitor process? You may be approaching
that limit if you've got 500 OSDs and a similar number of clients.

Unfortunately I have completely disabled logs during test, so there
are no suggestion of assert_fail. The main problem was revealed -
created VMs was pointed to one monitor instead set of three, so there
may be some unusual things(btw, crashed mon isn`t one from above, but
a neighbor of crashed osds on first node). After IPMI reset node
returns back well and cluster behavior seems to be okay - stuck kvm
I/O somehow prevented even other module load|unload on this node, so I
finally decided to do hard reset. Despite I`m using almost generic
wheezy, glibc was updated to 2.15, may be because of this my trace
appears first time ever. I`m almost sure that fs does not triggered
this crash and mainly suspecting stuck kvm processes. I`ll rerun test
with same conditions tomorrow(~500 vms pointed to one mon and very
high I/O, but with osd logging).

This means it got an unexpected error when talking to the file system. If
you look in the osd log, it may tell you what that was. (It may
not--there isn't usually the other tcmalloc stuff triggered from the
assert handler.)
What happens if you restart that ceph-osd daemon?

Hi,
today during heavy test a pair of osds and one mon died, resulting to
hard lockup of some kvm processes - they went unresponsible and was
killed leaving zombie processes ([kvm] <defunct>). Entire cluster
contain sixteen osd on eight nodes and three mons, on first and last
node and on vm outside cluster.

Sorry that was my build system it accidently removed the .git dir while
builing so the version string couldn't be compiled in.
It was 5efaa8d7799347dfae38333b1fd6e1a87dc76b28

Hi Stefan,
I opened http://tracker.newdream.net/issues/2599 to track this, but the
dump strangely does not include the ceph version or commit sha1. What
version were you running?
Thanks!

Yes (though --mkjournal is implied by --mkfs). I just wrote a quick wiki
page for this:

Great information. I appreciate it. Actually, I am running SAS RAID controllers (probably not what I will do in production). Each disk is configured as raid 0 so that it shows up in Linux as a single drive each. I think 100% of the problem is with the RAID controller re-insertion of a disk in a RAID 0 group.
Would it be better to use a HBA (without RAID) for SATA/SAS2 16 port? Does anyone know how a failure and an a reinsertion of a new drive will be handled with these type of HBAs? I assume that a manual --mkfs --mkjournal for the osd is required in addition to the a restart of the particular cosd?

I am assuming that you are using serial ATA (SATA), because that is
what comes standard on most PCs these days. The last time I used SATA
hotplug, which was in 2009, the driver support was still pretty flaky
at the chipset level. Things may have improved since then, but I
suspect that SATA hotplug is still an uncommon and poorly tested
operation.
If you really want to get hotplug working, start with the basics--
just see whether it works at the driver and block device level. Then
get btrfs involved, and finally if all that works, try Ceph.
However, it might be simpler just to simulate failures by randomly
killing cosd processes.
When cosd hangs on a sync for too long, it will deliver a SIGABRT to
itself anyway. So the only part of the proecss you would be bypassing
is the hang. You're putting your SATA driver and btrfs's error
handling paths through a workout, but not really testing Ceph per se.

I am assuming that you are using serial ATA (SATA), because that is
what comes standard on most PCs these days. The last time I used SATA
hotplug, which was in 2009, the driver support was still pretty flaky
at the chipset level. Things may have improved since then, but I
suspect that SATA hotplug is still an uncommon and poorly tested
operation.
If you really want to get hotplug working, start with the basics--
just see whether it works at the driver and block device level. Then
get btrfs involved, and finally if all that works, try Ceph.
However, it might be simpler just to simulate failures by randomly
killing cosd processes.
When cosd hangs on a sync for too long, it will deliver a SIGABRT to
itself anyway. So the only part of the proecss you would be bypassing
is the hang. You're putting your SATA driver and btrfs's error
handling paths through a workout, but not really testing Ceph per se.

So:
- cosd is running fine
- you pull the drive
- cosd hangs, cluster marks it down, recovers
- reinsert the drive
and then
- cosd gets EIO
or
- cosd won't restart
?
It sounds like the problem is that btrfs isn't handling the online
reinsertion of the disk. If you restart the machine things should come
up.
I'm not sure whether handling those kinds of transient disk errors is
something btrfs is intended to handle any time soon (without a reboot).
This is one downside to multiple osds and btrfs volumes on the same node:
if any one btrfs volume hangs up for some reason, the whole node is
affected (one kernel!) and needs to be restarted.

Some additional testing shows that the underlying filesystem btrfs does fail thus the daemon appropriately fails.
The way I am simulating a failed HDD is by removing the HDD. The failure is working, but the problem is when I reinsert the HDD. I think I see the BTRFS filesystem recovery (btrfs filesystem show) and I can start the correct osd daemon that corresponds to the mount point but I do not see the osd come up and in (ceph -s). The log is limited to

If I try to restart the osd daemon, it is unable to kill the process and repeats trying to kill it.
Is the underlying file system not recovery like I think? I guess removing and inserting the HDD isn't the correct way to simulate a dead HDD.? Show I following the process of removing the osd, initializing the osd data dir and then restart the osd daemon?
Thanks.

Subject: OSD Crash
I was performing a few failure test with the osd by removing a HDD from one of the osd host. All was well, the cluster noticed the failure and re-balanced data but when I replace the HDD into the host, the cosd crashed.
Here is my setup. 6 osd host with 4 HDDs each (4 cosd daemons running for each host). 1 mon and 2 mds (separate host).
Here is the log from the osd0
