while read, is not looping with ssh.
echo will print all the lines, ssh will not. see below. why is this.

Code:
[root@localhost script]# awk -F: '{print $1,$2,$3}' vfiler_volumes.list | while read filer vfiler vol ; do echo $filer $vfiler $vol ; done
node1 vfiler0 /
node1 vfiler2 /vol/vfiler2_vol0
node1 vfilert /vol/vfiler_vol
node1 vfilert /vol/virt_vol


[root@localhost script]# awk -F: '{print $1,$2,$3}' vfiler_volumes.list | while read filer vfiler vol ; do ssh $filer vfiler run $vfiler df -h $vol ; done

===== vfiler0
Filesystem               total       used      avail capacity  Mounted on
/vol/vol0/               241MB      106MB      135MB      44%  /vol/vol0/
/vol/vol0/.snapshot        0MB       16MB        0MB     ---%  /vol/vol0/.snapshot
[root@localhost script]#
