Hi,
I am sometimes getting these errors in my bacula backups:
Fatal error: device.c:192 Catastrophic error. Cannot write overflow block to device
"DiskStorage-drive-0"
and it is more likely on the larger volume backups. It seemingly
results from bacula trying to write an additional block to a disk
drive that is already 100% full. How can I stop bacula from believing
this is a valid thing to do?
You don't. The trick is to define a maximum volume size and number of
volumes on the drive so that it is impossible to reach 100% of the
physical drive's capacity. This will prevent the i/o error, and Bacula
will instead hit end of volume and seek another volume. Of course, if no
existing volumes can be recycled yet, then there simply isn't enough
space on the drive. In that case, it is easy to add another drive to an
existing autochanger, since vchanger allows for multiple simultaneous
"magazine" drives.
Background: I have bacula setup on my local network to backup a file
server and a number of workstations. The file server is also the
bacula director and is running Fedora 15 and
"bacula-common-5.0.3-28.fc15.x86_64". Bacula is writing backups to an
iSCSI disk group (not array) over ethernet; there are 6 disks of 1TB
to 2TB size and these are managed using "vchanger" 0.8.6, with 6
magazines each with 24 virtual volumes. The file server has 3.5TB of
files and other workstations add about another 1TB.
