Description

Looking around my logs noticed this:

== replay-vbr test 1b: open (O_CREAT) checks version of parent ======================================= 17:17:44 (1566163064)
Starting client: oleg230-client.virtnet:  -o user_xattr,flock oleg230-server@tcp:/lustre /mnt/lustre2
mount.lustre: according to /etc/mtab oleg230-server@tcp:/lustre is already mounted on /mnt/lustre2
oleg230-server: error: set_param: param_path 'mdd/lustre-MDT0000/sync_permission': No such file or directory
pdsh@oleg230-client: oleg230-server: ssh exited with exit code 2

Some digging around reveals the the setting is actually named

LUSTRE_RW_ATTR(sync_perm);

not sure what's up with the double mount attempt, probably a separate issue.
