Hi, when dump is used on an mdconfig mount it doesn't work: # dump -0aLf - /vol0/jail/alpha | ( cd /vol0/jail/beta ; restore -ruf - ) DUMP: WARNING: Cannot use -L on an unmounted filesystem. dump: /vol0/jail/alpha: unknown file system Tape is not a dump tape # mount | grep alpha /dev/md0c on /vol0/jail/alpha (ufs, local, soft-updates) devfs on /vol0/jail/alpha/dev (devfs, local) # df -h | grep alpha /dev/md0c 9.7G 381M 8.5G 4% /vol0/jail/alpha devfs 1.0K 1.0K 0B 100% /vol0/jail/alpha/dev If I test it with /dev/md0c instead of /vol0/jail/alpha, it works fine. # dump -0aLf - /dev/md0c | ( cd /vol0/jail/beta; restore -ruf - ) DUMP: Date of this level 0 dump: Tue May 8 11:13:13 2007 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping snapshot of /dev/md0c to standard output DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 445288 tape blocks.

Is there any PR for it? FreeBSD 6.2-RELEASE-p4 Miroslav Lachman
