We saw similar messages in earlier versions of NetWorker (either v6.1.3
or v7.1.1, can't remember which) when the tape was empty or contained
VERY little data. The explanation I got from Legato was that the block
size reported was the size of the initial header block rather than a
data block.

Subject: [Networker] More NW 7.3 oddness.
I just opened the following case. Might be good to know for others who
experience similar issues:
---
It seems like the block size in networker 7.3 doesn't work as expected
for
devices. With 7.2.1, we
used the following in the networker startup script to set the block
size:
set NSR_DEV_BLOCK_SIZE_SAIT_1=64
export NSR_DEV_BLOCK_SIZE_SAIT_1
We have modified the networker 7.3 startup script to reflect this. We
have
also configured all
devices to use 64kb blocksize in the networker admin GUI. However, this
doesn't seem to work
anymore, because we get the following error:
(from daemon.log):
01/10/06 13:28:23 nsrd: media notice: Volume "007494S1" on device
"rd=sn01:/dev/nst0": Block size is 32768 bytes not 65536 bytes. Verify
the
device
configuration. Tape positioning by record is disabled.
The tape was just labeled, and an old volume was overwritten, which had
a
block size of 64kb. The
tape was moments before labeled in the same drive as the error occured
in.
Worth noting (altoigh not directly related to this issue) is that it now
waits for more tapes to be
mounted than there are available devices, which makes it relabel tapes
instead of mounting existing
non-full tapes in that pool. In NW 7.2.1, no more tape mount requests
were
listed as pending when
there were no more available devices to mount them in.
---
In general, NW 7.3 feels like an immature product, full of old code that
has been temporarily fixed and patched, with a "new" Java GUI which
makes
monitoring of server operations more difficult. It seems common that
things that were fixed by a hack in one release are then gone in the
next
one. To summarize: with NW, I feel like I'm constantly beta-testing it.
And considering how much stuff I tend to come up with... well..
