I am trying to dump a small partition: mi@aldan:~ (939) df -k Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/sd0a 521294 230878 248714 48% / as follows: mi@aldan (233) rdump 0uf rtfm:/dev/rst0 / Unfortunately, dump thinks, I'm going to need six tapes: DUMP: Date of this level 0 dump: Fri Feb 21 12:37:48 1997 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/rsd0a (/) to /dev/rst0 on host rtfm DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 235075 tape blocks on 6.05 tape(s). DUMP: dumping (Pass III) [directories] and does, indeed ask for more and more (I gave it two, just to see what's going to happen). My attempts to give it some other /dev/rst0* devices lead to Input/Output error. I am going to play with s, d, b, and a flags, but should not dump/rmt be smart enough to detect my tape capabilites on their own? -mi -- "Windows for dummies"
