Dear All,

I am trying to set quota on lustre but unfortunately i have issued the
below commands:-

tunefs.lustre --param ost.quota_type=ug /dev/mapper/mds1
checking for existing Lustre data: found
Reading CONFIGS/mountdata

   Read previous values:
Target:     data-MDT0000
Index:      0
Lustre FS:  data
Mount type: ldiskfs
Flags:      0x1001
              (MDT no_primnode )
Persistent mount opts: user_xattr,errors=remount-ro
Parameters:  mgsnode=192.168.2.9 at o2ib:192.168.2.10 at o2ib
failover.node=192.168.2.9 at o2ib:192.168.2.10 at o2ib

   Permanent disk data:
Target:     data-MDT0000
Index:      0
Lustre FS:  data
Mount type: ldiskfs
Flags:      0x1041
              (MDT update no_primnode )
Persistent mount opts: user_xattr,errors=remount-ro
Parameters:  mgsnode=192.168.2.9 at o2ib:192.168.2.10 at o2ib
failover.node=192.168.2.9 at o2ib:192.168.2.10 at o2ib ost.quota_type=ug

After this i have issued lctl conf_param home.quota.mdt=ugp and now i am
able to see quota enabled in mdt but will there be any affect to the above
version as i have issue that command to 2 mdts where i am having 4 mdts in
total. Do i need to issue any further commands to revert those.

After enabling quota and file space crossed soft limit but i am unable to
get warning till it reached near hard limit.

Can anyone help me out.

Thanks,
ANS
