Hi All,
I had a failure of my Amanda index drive. I am now trying to restore some
archives. What I have done so far is the following:
Ran amrestore to get a listing of tape contents
dendron:/mnt/dump_drive/restore# mt -t /dev/nst0 rewind
dendron:/mnt/dump_drive/restore# amrestore /dev/nst0 no.such.host
amrestore: 0: skipping start of tape: date 20050304 label Project223
amrestore: 1: skipping
dendron.l8r.net._mnt_vxa2_scans_c_Seven__Pent22.20050304.0
amrestore: 2: skipping
dendron.l8r.net._mnt_vxa2_scans_c_Seven__Unix.20050304.0
amrestore: 3: skipping
dendron.l8r.net._mnt_vxa2_scans_c_Seven__Pent21.20050304.0
amrestore: 4: skipping
dendron.l8r.net._mnt_vxa2_scans_c_Seven__Final__Sids.20050304.0
amrestore: could not fsf /dev/nst0: Input/output error
determined that what I need is in file
2: dendron.l8r.net._mnt_vxa2_scans_c_Seven__Unix.20050304.0
So I:
mt -t /dev/nst0 rewind
mt -t /dev/nst0 fsf 2
dd if=/dev/nst0 bs=32k count=1
This list the following:
AMANDA: FILE 20050304 dendron.l8r.net /mnt/vxa2/scans/c/Seven_Unix lev 0
comp .gz program /bin/tar
To restore, position tape at start of file and run:
dd if=<tape> bs=32k skip=1 | /bin/gzip -dc | bin/tar -f... -
So I rewind the tape skip 2 files and then issue:
dd if=/dev/nst0 bs=32k skip=1 | /bin/gzip -dc | /bin/gtar -f ????
I tried various things as substitutes for ???? such as
/mnt/vxa2/scans/c/Seven_Unix and
dendron.l8r.net._mnt_vxa2_scans_c_Seven__Pent22.20050304.0
Results is always an error similar to the following:
/bin/tar: dendron.l8r.net._mnt_vxa2_scans_c_Seven__Unix.20050304.0: Cannot
open: No such file or directory
/bin/tar: Error is not recoverable: exiting now
/bin/tar: Child returned status 2
/bin/tar: Error exit delayed from previous errors
1+0 records in
0+0 records out
0 bytes transferred in 0.021878 seconds (0 bytes/sec)
Any pointer to what I should be putting on the final command line would be
appreciated.
Thanks,
Vytas
