[LU-9104] Unknown config param in llog fails mounting target

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.10.1, Lustre 2.11.0
• Severity: 3
• Assignee: James A Simmons
• Reporter: Rahul Deshmukh (Inactive)

Description

If we have unknown config parameter in llog then it fails the target mounting.

Steps to re-create it are as :

$>sh llmount.sh
$>export NOFORMAT=yes
$>for OST in $(lctl get_param mgs.MGS.live.lustre | grep OST); do echo "max_rpcs_in_flight=50 on $OST" ; lctl conf_param $OST.ost.max_rpcs_in_flight=50 ; done <--- Note here ost.max.. is mention instead of osc.max..
$>sh llmountcleanup.sh
$>sh llmount.sh <------- this hangs, as ost is not avilable
