== sanity test 247e: mount .. as fileset ================= 09:22:38 (1721222558)
Starting client: oleg260-client.virtnet:  -o user_xattr,flock oleg260-server@tcp:/lustre/.. /mnt/lustre_d247e.sanity
mount.lustre: mount oleg260-server@tcp:/lustre/.. at /mnt/lustre_d247e.sanity failed: Invalid argument
This may have multiple causes.
Is 'lustre/..' the correct filesystem name?
Are the mount options correct?
Check the syslog for more info.
