The reason I am asking is becasue we get complaints from dump all the time,
like:
DUMP: read error from /dev/rsd1h: Invalid argument: [block -1444115938]: count=8192
DUMP: bread: lseek2 fails!
DUMP: read error from /dev/rsd1h: Invalid argument: [sector -1444115938]: count=512
...]
bread: lseek fails
DUMP: DUMP: DUMP: bread: lseek fails
read error from /dev/rsd1h: Invalid argument: [sector -126001564]: count=512
bread: lseek fails
and this repeated all the time.
We also see empty messages from the scsi subsystem around the backup time.
That might also explain some things:
