Public bug reported:
The cron job for zfsutils-linux fails to run. The problem is that $PATH
(on xenial, at least) is set to /bin:/usr/bin. The zpool binary is in
/sbin and the /usr/lib/zfs-linux/scrub script (below) doesn't give the
full path or modify $PATH. Further, the 2>&1 ensures that the useful
error is sent to awk and not stderr where it'd be more easily noticed.
The fix is to just s,zpool,/sbin/zpool, in the script. And probably
remove the stderr redirection, since I'm not sure if it's actually
useful here.
This is the script as it currently is, for reference:
#!/bin/sh -eu
# Scrub all healthy pools.
zpool list -H -o health,name 2>&1 | \
awk 'BEGIN {FS="\t"} {if ($1 ~ /^ONLINE/) print $2}' | \
while read pool
do
zpool scrub "$pool"
done
