Recover failed Ganesha node - which mark with F flag, without reboot.

Hi

We had NFS Ganesha node that failed - but we did not able to recover it , only reboot solve it.


Sysmon attempted to remove the F flag three times, but all attempts to acquire the lock failed.
As a result, the node remained in a failed state despite being healthy.
Restarting the node allowed the process to retry successfully once the lock became available.

NFS failure: RPC null checks and the stat checks (collects IO number 2 times and if its the same, the test fails) both failed. thats why nfs_not_active. This was fixed soon.
why node stayed in failed state even NFS was healthy: But to remove Failed state we need a fail-over lock and we didn't get it, it tries 3 times. Later when the lock was available, we had already exhausted our tries. And this is working as designed. But ideally we may want to redesign this.
