  | Filesystem  1K-blocks     Used     Avail Capacity  Mounted on
  | filer:/     1203059592   136500 1202923092     0%    /filer

  | %=20
  |=20
  |=20

Not specifically, because last I looked filers still had a 1.4 TB raw
limit per volume.  That may have been fixed recently.

It's still worth looking at, because 2 TB is achievable for under U$2K,


Cheers,
