I think that list is dead. Can anyone help? Thanks. ---------- Forwarded message ---------- From: Tape Help Date: Fri, 14 Jan 2005 02:53:16 -0500 Subject: Multi tape problems with cpio To: linux-tape@vger.kernel.org I am using cpio to backup a system. The backup does not fit on 1 tape, so cpio prompts for another tape. I change the tape and hit enter. cpio continues and completes. cpio does eject the first tape, which is handy. When I try to list the tape, cpio gets an I/O error at the end of the first tape and does not prompt for a second tape. Same problem if I try to restore data. cpio: read error: Input/output error I have tried 2 different tape drives. Both give the same results. I have done this test about 5 or so times. The backup command: find MyFS -depth|cpio -o --format=newc --block-size=128 -F /dev/st0 The command to list the tape(s): cpio -i --only-verify-crc --list --block-size=128< /dev/st0 If I use dd to read the tape, it also gets a read error at the end. I think it should get an end of file and exit cleanly. I am using kernel 2.4.28. It also fails with 2.4.20-8. Anyone have any ideas? Sort of funny, at first only 1 tape was needed. I tested that I could restore from the tape and it worked. It has been using 2 tapes for over 6 months now. I had no idea my backups have been bad for over six months! I can still restore from the first tape. Thanks.
