    Description

      build: b2_10 #2 tag-RC1

      When testing the ZFS Snapshot with Subdir Mount, I found that the lctl snapshot_* command only works with ssh, with rsh, it returns error. I have tried with both snapshot_create and list, both return the same error.

      with ssh:

      [root@onyx-69 ~]# lctl snapshot_list -d -F lustre --name test-snap

filesystem_name: lustre
snapshot_name: test-snap

create_time: Fri Jul  7 21:26:41 2017

status: not mount

      try with same environment but with rsh option

      [root@onyx-69 ~]# lctl snapshot_list -d -F lustre --name test-snap -r rsh
bash: zfs: command not found
Can't list the snapshot test-snap
[root@onyx-69 ~]#

      The rsh did work between nodes.

      [root@onyx-69 ~]# rsh onyx-70
