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?

Hi, If you changed the NID of the servers, you need to do writeconf to let MGS erase and regenerate the system configuration. First you need to shutdown the system, do writeconf on all the targets(MDT/OST), then you can restart the system in the order of MGS, MDT, OST, client. Make proper change in the lnet options in /etc/modprobe.conf to reflect your NID info. If you change the NID of the MGS, additional work needs to be done to let your server targets correctly communicate with the MGS. But since you only changed the NID of the OSTs, you don''t have to worry about this. ? 2010-12-16???1:50?

I actually did run writeconf on the MGS/MDS as well. I just did it again to test. Followed the instructions in section 4.3.11 in the luster manual. Mounting MDT goes fine. Mounting the OSTs, the first just seems to be hanging. The other two both gave: [root at ost2 ~]# mount -t lustre /dev/VG_lustre/scratch_ost2 /mnt/lustre/scratch/ost2/ mount.lustre: mount /dev/VG_lustre/scratch_ost2 at /mnt/lustre/scratch/ost2 failed: Function not implemented Currently running e2fsck on the two OSTs that didn''t want to mount.

This error sounds like that there is some unrecognized parameter(s) on your OSTs. Please check your OST parameters.

Thank you for your assistance. I am almost there. I am able to get all the OSTs to mount, but when I do "lctl dl", one of them is not showing up for the work filesystem. I can ping all OSSs from each other and once I have done that see them all in a peer_list. I have even tried mounting the OST on an OSS that already has another OST that is being recognized.

I am focusing my effort on the simplest lustre filesystem consisting of a single OST. I can mount the MDT/MGS and the OST with no apparent errors.
