Hi all,

I'm currently running a test TSM server using v5.5.4.0 and I'm
experimenting with backing up to removable USB drives.

One thing I've noticed is that when a drive is around 50-60% full I get an
ANR8341I End-of-volume event in the logs and a new volume is asked for.
While I would expect this for a full volume, I wouldn't expect it with a
half full volume.

I have posted this issue at the following URL however at the moment I
haven't had any insightful replies:

For those who hate forums, I have copied the most relevant information
below:

When the volume gets full, I get the following:
01/24/2010 14:46:49      ANR8335I 003: Verifying label of REMOVABLEFILE
volume 5QD7CKPM in drive USBDRIVE (/mnt/usb). (PROCESS: 5)

When looking at the filesystem, I see:

/dev/sdk1             294G  180G   99G  65% /mnt/usb

drwx------ 2 root root        16384 Jan  7 12:54 lost+found

Does anyone have any theories on this?
