[LU-9747] posix.sh needs to check for zfs on servers rather than clients

• Type: Bug
• Resolution: Won't Fix
• Priority: Minor
• Affects Version/s: Lustre 2.10.0, Lustre 2.12.0, Lustre 2.13.0
• Labels: ZFS
• Environment: full group zfs configs (el7+el7+zfs & el7+el7+zfs+dne)

Description

Here's a recent example of posix being skipped on a zfs config:

https://testing.hpdd.intel.com/test_sessions/f38b5926-8503-4f08-9e4b-9f7cd561db9d

It looks like the script is checking for zfs on the client:

  18 if [[ $(facet_fstype $SINGLEMDS) = zfs ]]; then
  19         BASELINE_FS=zfs
  20         ! which $ZFS $ZPOOL >/dev/null 2>&1 &&
  21                 skip_env "need $ZFS and $ZPOOL commands" && exit 0

Line 20 should return false if run on servers, but not on clients:

From MDS/OST:

1. which zfs zpool
   /usr/sbin/zpool
   /usr/sbin/zfs

From clients:

1. which zfs zpool
   /usr/bin/which: no zfs in ($PATH)
   /usr/bin/which: no zpool in ($PATH)
