The ZFS scrub completed without any errors/corrections.
Following the scrub (and clearing all users from our cluster login nodes) I
remounted the MDT and it appears to be running fine (just running the remaining
batch jobs). I'm now able to get onto our monitoring system - hopefully a look

Hi Nick-
If there is no MDS/MGS/OSS currently hosting a particular MDT/MGT/OST, then
what is stored there will not be accessible. I suggest looking at

Hi Shambhu-
I believe neither the ldiskfs nor ZFS OSDs support an active-active
configuration (except in the sense that one can have multiple targets, some of
which are active on one host and others on another). It seems reasonable to
me, only having used DRBD and Lustre independently of each
Hi Colin,
Not yet, we last scrubbed the pool ~2 weeks ago when we first saw this problem.
I've got a few additional tests to run now to see if we can track the cause to
a particular job/process, but kicking off a scrub is my next thing to do (It
should only take ~40 minutes, it's a fairly
Have you tried resilvering the pool?

We have a problem on our production Lustre/ZFS filesystem (CentOS 7, ZFS
0.7.13, Lustre 2.12.9), so far I've drawn a blank trying to track down the
cause of this.
We see the following zfs panic message in the logs (in every case the

Hi
Okay. Thank you for the information
Can you tell if the MDS/MGS or the OSS server goes down, how will the
failure be handled on Lustre level?

No, because the remote-attached SSDs are part of the ZFS pool and any drive
failures a t that level are the responsibility of ZFS in that case to manage
the failed drives (eg. with RAID) and for you to have system monitors in place
to detect this case and alert you to the drive failures. This
Hi
There is a situation where disks from multiple servers are sent to a main
server.(Lustre storage) Zpool is created from the SSDs and mkfs.lustre is
done using zfs as a backend file system. Lustre client is also connected.
If one of the nodes from where the SSDs are sent goes down, will the
