From: Johnny on 14 Apr 2005 09:36 I've backed up the /dev/rdsk/c0t0d0s7 filesystem to a 7 tape DLT unit using ufsdump 0lucf IP.IP.IP.IP:/dev/rmt/0n /dev/rdsk/c0t0d0s7 No errors occured and it spanned 3 tapes. So I mount the first tape and try a ufsrestore on the server the tape drive is attached to ufsrestore -i /dev/rmt/0 cd /dir/dir/dir add filename extract It asks me to specify the next volume so I use '1' it then asks for the volume name I use /dev/rmt/0 it mounts volume 1 and then later asks me to specify the next volume I choose '2' and it errors saying 'wrong volume(1)' What on earth am I doing wrong here? Any help would be most grateful!

I believe that working from the last volume toward the first is for the best efficiency. It should not be required to make it work. I expect that the reason for the 'wrong volume(1)' error is that the drive did not switch tapes. Perhaps you need to manually make the drive use tape 2. -- Tom Schulz schulz(a)adi.com

I noticed that - weird! What if a file stems over onto two tapes. Surely you'd want the first tape first!! I haven't used ufsrestore in years (about 10 years or so)

I haven't used ufsrestore in years (about 10 >years >or so) It would treat a tape with only the last part of a file the same as a tape without the file at all. It would tell you to switch to the next previous tape. For tapes after the one containing the requested file, restore can reject the tape quickly as it has read the table of contents from the first tape and therefore can tell that the tape is after the one containing the file. For tapes before the one containing the requested file, restore has to read the whole tape to find out that the file is not on the tape. -- Tom Schulz schulz(a)adi.com |
