Some filesystems won't unmount 24# because they're busy. Some won't remount because they were legacy mounts in 25# the first place. etc... 26# Make a best approximation by calling umountall with the -n option, and verify 27# that the list of things it would try to unmout makes sense. 28# 29# STRATEGY: 30# 1. Make a list of file systems umountall is known to ignore. 31# 2. Append all ZFS file systems on this system. 32# 3. Run umountall -n and verify the file systems it reports are in the list. 33# 34 35log_must zfs mount -a 36for fs in 1 2 3 ; do 37 log_must mounted $TESTPOOL/$TESTFS.$fs 38done 39 40# This is the list we check the output of umountall -n against. We seed it 41# with these values because umountall will ignore them, and they're possible 42# (though most are improbable) ZFS filesystem mountpoints. 43zfs_list="/ /lib /sbin /tmp /usr /var /var/adm /var/run" 44 45# Append our ZFS filesystems to the list, not worrying about duplicates. 46for fs in $(mount -p | awk '{if ($4 == "zfs") print $3}'); do 47 zfs_list="$zfs_list $fs" 48done 49 50fs='' 51for fs in $(umountall -n -F zfs 2>&1 | awk '{print $2}'); do 52 for i in $zfs_list; do 53 [[ $fs = $i ]] && continue 2 54 done 55 log_fail "umountall -n -F zfs tried to unmount $fs" 56done 57[[ -n $fs ]] || log_fail "umountall -n -F zfs produced no output" 58 59log_pass "All ZFS file systems would have been unmounted" 60
