Hello,
In a pickle now..
I upgraded our lustre from 1.8.4 to 1.8.5.
We have an LVM that contains the MDTs and OSTs and is accessible via SRP. That
seems to work without issues.
I did change IPs of the NID for 2 or our lustre filesystems.
Made appropriate changes to each ost. One thing I did that I probably shouldn't
have was doing a --writeconf on the OSTs. Now I see:
Flags: 0x142
(OST update writeconf )
and I cannot mount them. I get:
mount.lustre: mount /dev/VG_lustre/scratch_ost1 at /mnt/lustre/scratch/ost1
failed: Function not implemented
however I do seem to be able to mount the OSTs that I didn't do --writeconf on.
I see in syslog:
LustreError: 6182:0:(obd_mount.c:1097:server_start_targets()) Required
registration failed for nscratch-OST0001: -38
LustreError: 6182:0:(obd_mount.c:1655:server_fill_super()) Unable to start
targets: -38
LustreError: 6182:0:(obd_mount.c:1438:server_put_super()) no obd
nscratch-OST0001
LustreError: 6182:0:(obd_mount.c:147:server_deregister_mount())
nscratch-OST0001 not registered
LustreError: 6182:0:(obd_mount.c:2050:lustre_fill_super()) Unable to mount
(-38)
Is there a way to clear the flags on an OST and get it to mount?
