[lustre-discuss] Lustre Precreation error.

[Andrea del Monaco]

Dear all,

We are facing an issue with one OST.
We have stopped pacemaker on the storage06 (which is the one that has that
resource running):
[root at storage06 log]# pcs status | grep 1b
storage-ost001b (ocf::heartbeat:Filesystem): Started
storage06.failover.cluster
storage-ost001b_monitor_120000 on storage06.failover.cluster 'not running'
(7): call=295, status=complete, exitreason='none'
*
And then we have tried to execute e2fsck -n /dev/mapper/ost001b.
The e2fsck has reported nothing to be repaired.
Today, i noticed that there are still errors and we can't create files on
this OST:

Llooking at cat /usr/include/asm-generic/errno.h, seems that error refers
to:
#define EINPROGRESS 115 /* Operation now in progress */
#define ESTALE 116 /* Stale file handle */
(on some other osts we do have error 116 as well)

Any idea about what to do next?

I will increase the verbose and dump the logs from the ring buffer.

Kind regards,
