[Lustre-discuss] error while upgrading 1.6.5 to 1.6.7.2

[Michal Bialoskorski]

Thank You Nirmal very very much. "home" is working now.  Now I will 
upgrade/recover the second fs.

Summing it up what I've done is:

on MDS:
1) /opt/lustre/sbin/tunefs.lustre --mdt --writeconf   --erase-param  \
     --param="mdt.group_upcall=/usr/sbin/l_getgroups"/dev/mapper/home.mdt
2) mount -t lustre -o abort_recov /dev/mapper/work.mdt /lustre/home.mdt
3) umount /lustre/home.mdt
4) mount -t lustre /dev/mapper/work.mdt /lustre/home.mdt

on OSSs for all OSTs:
1) tunefs.lustre --ost --writeconf  --erase-param 
--mgsnode=192.168.27.252 at o2ib /dev/mapper/home.ost.XX
2) mount -t lustre -o abort_recov /dev/mapper/home.ost.XX 
/lustre/home/ost.XX
