- For NFS4.1 and NFSv4.2 the 128 limit still applies and can be controlled by lowering the option for -v4.x-session-num-slot to 128 (default is 180).
- Verify settings (CLI)
set -privilege advanced
vserver nfs show -vserver <SVM_NAME> -fields v4.x-session-num-slots - Change settings
set -privilege advanced
vserver nfs modify -vserver <SVM_NAME> -v4.x-session-num-slots 128 - This will only apply to sessions created after the configuration change.
- Active sessions will use the previous -v4.x-session-num-slot configuration.
- nfsv4 maintains session, so if modify this option, it should be applied after remount and session recreated.
