Last modified: 2007-04-18 12:38:49 EDT
Description of Problem: Any restore operation on a dump file stored on an HP Colorado 20Gb IDE tape drive gives a "tape read error" and fails. Version-Release number of selected component (if applicable): HP Colorado 20GB rev 4.01, RH 7.1 How Reproducible: every time Steps to Reproduce: 1. /sbin/dump -0u -f /dev/nht0 /home >> successfully dumps to tape 2. mt -f /dev/nht0 tell >> At block 227181 (for example) 3. mt -f /dev/nht0 rewind 4. /sbin/restore -i -f /dev/nht0 (or any other restore option) >> "tape read error: Input/output error" and return to prompt. no tape movement happens on the restore. /var/log/messages: Dec 23 13:56:49 localhost kernel: ide-tape: Reached idetape_chrdev_open Dec 23 13:56:49 localhost kernel: ide-tape: ht0: I/O error, pc = 8, key = 5, asc = 2c, ascq = 0 Actual Results: Expected Results: Additional Information:
Just tested tar in the same way. Tar to tape works fine, tar read from tape fails: at the command line, error is: [root@localhost /]# tar tvf /dev/nht0 tar: /dev/nht0: Cannot read: Input/output error tar: At beginning of tape, quitting now tar: Error is not recoverable: exiting now Error in /var/log/messages is identical to restore failure. This definitely worked in earlier version (6.2). I hadn't used dump/restore under that version.
Please make sure your system is updated with all Red Hat Linux erratum updates, including dump and the kernel. Update the report please after updating to let me know the status of your results. Thanks
Problem reported solved in the rawhide version of dump.
