Dear all:

My Environment:  two servers, and 12 hard-disk on each server.
                  Version: Ceph 0.48, Kernel: 3.2.0-27

 We create a ceph cluster with 24 osd, 3 monitors
 Osd.0 ~ osd.11 is on server1
 Osd.12 ~ osd.23 is on server2
 Mon.0 is on server1
 Mon.1 is on server2
 Mon.2 is on server3 which has no osd

We create a rbd device and mount it as ext4 file system. 
During read/write data on the rbd device, one of the storage server is shutdown by accident. 
After reboot the server, we cannot access the rbd device any more.
One of the log shows the osdmap is corrupted.

Aug  5 15:37:24 ubuntu-002 kernel: [78579.998582] libceph: corrupt inc osdmap epoch 78 off 98 (ffffc9000177d07e of ffffc9000177d01c-ffffc9000177edf2)

We would like to know what kind of scenario would cause the corruption of osdmap and how to avoid it?
It seems that osdmap corruption cannot be recovered by the ceph cluster itself.

Is it the same issue with http://tracker.newdream.net/issues/2446?
In which version of kernel that we can find this patch? Thanks!

I'm not sure if it's the same issue, but looking at the Linux kernel 
tree, it seems as though that fix is in v3.5-rc1

Which kernel version are you running?

If it is that issue, simply restarting the client is a workaround.  It may 
crop up again on a newer epoch as the cluster recovers/rebalances data, 
but in each case a client restart will get past it.

If that doesn't work, please attach a copy of the incremental osdmap 
($mon_data/osdmap/78 from one of your monitors) and we can see what the 
actual corruption is.

Thanks!

Hello Eric,

We had the same problem and upgraded to the 3.5 kernel. The messages 
disappeared from dmesg. We had a 3.4.x running. Don't know the exact 
number anymore, but it was a low one (2 or something). So it seems that 
upgrading the kernel fixes the problem.

Stefan

Dear Sage and Dan:

Thanks for kindly reply.

If we want to patch http://tracker.newdream.net/issues/2446 on kernel 3.2, 
can we just modify the file as below? 
We are afraid that it may cause other side effect.

Which kernel version are you running?

If it is that issue, simply restarting the client is a workaround.  It may crop up again on a newer epoch as the cluster recovers/rebalances data, but in each case a client restart will get past it.

If that doesn't work, please attach a copy of the incremental osdmap
($mon_data/osdmap/78 from one of your monitors) and we can see what the actual corruption is.

Thanks!
