I started getting this error over the last week or so (nss-2.70-5008 and
5009). I found one of the drives had 15 media errors. I replaced the
drive and I am still getting these errors. The pool size is ~680gb.
Researching this error looks like I need to do perform a pool rebuild.
Is that correct? Also, any estimate on how long this would take? This
is our main production server. It is also the master of the tree. I
could possibly get another server setup to replace this one.

Netware 6 with sp3.
