Hi list, I have successfully set up our new department server using 4.3-RELEASE. I attached our DLT1 tape drive to the system and tried to do a backup. However i am unable to write and retrieve multiple filesystems to one tape. I had no problems with that under Solaris, Linux and OpenBSD , but under FreeBSD things seem to be a bit different. What i tried was: ----------------------------------------------------------------- root@antsrv1 [~] # mt rewind root@antsrv1 [~] # dump 0caf /dev/nrsa0 / DUMP: Date of this level 0 dump: Wed Sep 26 12:29:25 2001 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/ad0s1a (/) to /dev/nrsa0 DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 49239 tape blocks. DUMP: dumping (Pass III) [directories] DUMP: dumping (Pass IV) [regular files] DUMP: DUMP: 49254 tape blocks on 1 volume DUMP: finished in 31 seconds, throughput 1588 KBytes/sec DUMP: Closing /dev/nrsa0 DUMP: DUMP IS DONE root@antsrv1 [~] # dump 0caf /dev/nrsa0 /var DUMP: Date of this level 0 dump: Wed Sep 26 12:30:15 2001 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/ad0s1e (/var) to /dev/nrsa0 DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 4495 tape blocks.

I also played with filemarks, but to no avail. Any suggestions?
