Parallel dumps of a single file system?

Hi all,I have a 1 TB RAID5 array which I inherited. The previous admin configured it to be a single file system as well. The disklist I have set up currently splits this file system up into multiple DLEs for backup purposes and dumps them using gtar. In the past, on systems with multiple

I'm running vtapes on a new server. The vtapes are split across two external disk drives. Realizing that some tapes would not fill completely, I decided that rather than define the tape size to be exactly disk/N, I would add a fudge factor to the size. Things worked exactly as anticipated. The

Jon, There is no good short-term solution to this problem. Sorry. :-( Tape spanning helps, but is not a panacea. This is one of the limitations of the vtape API that I was talking about -- it tries to reimplement tape semantics on a filesystem, even when that doesn't make sense. When the
