[LU-19766] conf_param values are not enabled for newly mounted ost

• Type: Bug
• Resolution: Unresolved
• Priority: Medium
• Severity: 3
• Assignee: Rajeev Mishra
• Reporter: Rajeev Mishra

Description

when ost is mounted the conf_param is not read from the msg. Say msg enabled quota and 
ost is mounted after enabling the quota conf_param the new ost mount will not inherit the conf_param and reason for this is the ost does not read the conf_param from mgs
if you follow steps on two different host you can see this issue 

 ssh 10.103.18.154 'sudo mkfs.lustre --mgs --mdt --reformat --fsname=lustre --index=0 /dev/vdb1'

ssh 10.103.18.154 'sudo mkdir -p /mnt/mdt1'

ssh 10.103.18.154 'sudo mount -t lustre /dev/vdb1 /mnt/mdt1'

 ssh 10.103.18.154 'sudo mkfs.lustre --mdt --reformat --fsname=lustre --mgsnode=10.103.18.154@tcp --index=1 /dev/vdb2'

ssh 10.103.18.154 'sudo mount -t lustre /dev/vdb2 /mnt/mdt2'

ssh 10.103.18.154 'sudo lctl conf_param lustre.quota.ost=ugp'

 ssh 10.103.18.154 'sudo lctl conf_param lustre.quota.mdt=ugp'

ssh 10.103.18.26 'sudo mkfs.lustre --ost --reformat --fsname=lustre --mgsnode=10.103.18.154@tcp --index=0 /dev/vdb3'

ssh 10.103.18.26 'sudo mkdir -p /mnt/ost1'

 sudo mount -t lustre /dev/vdb3 /mnt/ost1

The new mounted ost will not have quota enabled
