Hey, all.
I've run Bacula off and on for several years, including v5 and v9, both
using disk for the backup media. I'm setting up my first instance using
tape, and Bacula 15. I keep intermittently running into I/O errors on
the tape, which seems to cause Bacula to declare the tape as "Full",
even if it's only used 10s of MB of a 30TB tape. Are there any general
recommendations for setup that I might have missed? Some kind of retry
mechanism? Some kind of tuning? I've already replaced SAS cables, and
it doesn't seem to make any real difference.
In this case, I'm running one RHEL 9.6 host, attached via SAS to 2
LTO-10 drives, in a Spectra Stack tape library. Using the stock Linux
tape drivers, not the IBM ITDT specialty driver. The other tenant in
the library (Versity) has not had issues even remotely resembling these.
I'm attaching an excerpt from the bacula log when the I/O errors
occurred. I'm still trying to find system logs from around the same
time. Any recommendations or pointers welcome.
Thanks,
Lloyd
