Ensure ssh isn't reading from standard input by using the -n option:
ZFSHEALTH=`/usr/local/bin/ssh -n $MACHINE "/sbin/zpool get health rpool" |
grep ONLINE | wc -l`
ZFSSTAT=`ssh -n -q $MACHINE /sbin/zpool status rpool`

I have this script work is failing on all hosts except the first one.
I have narrowed it down to the ssh statement. For some reason the ssh
statement causes the script to exit after the first host.
Any ideas why the ssh statement would cause the ext script to exit after
the first host ?
