NSS Rebuild - Portlock

Hi!

On a NW server 6.0 SP5 compare the below message after I start a poolverify
with:

Nss /poolverify

Errors: NONE
Unaccounted Blocks exist.
Pool System Report 'Blocks in use' in error


Server first was started with server -na (without autoexec.ncf)

I'm unable to image the sys-vol with Portlock 3.36. After the check compare:

Unassigned Block: 45
Errors within the NSS file system
Run a "Pool Verify" and confirm that there are no errors.
Possible pool corruption
Pool rebuild may be required to correct this problem-

The server is running without problems. I have a ArcServe backup of the sys
but how can I bring it back if the rebuild operation fails?

What are the risks off a nss /poolrebuild ?

Thanks,
Horst Kerschbaumer

AIUI, you remove the copy on disk (delete the pool) and do a full
restore. The backup experts here can give you more detail, but you might
also browse novell.support.netware.6x.server-backup. Definitely more work
than trying the rebuild, which I would expect to succeed.

Some small percentage of the time, a poolrebuild will lose some portion of
the data on the pool. I'm not sure, but those few cases may be total
trashing of the pool. If you have the latest version of NSS on your
six-oh machine, that should help avoid that risk. I've only done a few
rebuilds, so my stats aren't any use to you (they all succeeded, though).
I think "small percentage" means "< 1%", but will defer to the masters on
this.
