- | PROBLEM(S!):
- | Since sunday we are getting the following messages in SYSLOG
- | on one of our machines:
- |
- | Aug 26 05:00:04 poly1 unix: ips0d0s6 (/usr): uncorrectable error (code 23) chs=179/9/46 ...about to do first retry
- | Aug 26 05:00:12 poly1 unix: ips0d0s6 (/usr): uncorrectable error (code 23) chs=179/9/46 ...about to do second retry

- | Aug 26 05:00:12 poly1 unix: ips0d0s6 (/usr): uncorrectable error (code 23) chs=179/9/46 ...FATAL

- | DIAGNOSIS (from TAC): Hard disk is going ...
-
- Correct.
-
- | CURE (from TAC): Get a new hard disk ...
-
- Also correct, although reformatting the disk might help for a short
- while (but doesn't solve your other problem)
-
- | MAJOR PROBLEM: The system manager for that machine
- | did not do a backup of the system since installing
- | 4.0.1, and there have been major changes and fixes
- | (e.g., Mail). He is on vacation as well. If we do
- | a backup of the entire system now, it will be corrupt
- | (I think) since we get I/O errors doing even a simple
- | ls command.
-
- The backup won't be corrupt, except for those files that are shot
- anyway. Some backup programs may abort when trying to read the
- bad files, so you may have to arrange your backups to avoid them.
-
- | QUESTION: How can the changes that have been made best
- | be preserved?
- |
- | I can think of two strategies:
- |
- | (1) Back up the entire system, and then reinstall 4.0.1 after
- | dumping the backup tape onto the new disk.
-
- Do it the other way around; backup only the non-system files,
- plus config files and other modified files (i.e., the output
- of "versions changed"). Some of those changed files may be due
- to the disk problems; others because we change some files at
- installation time, and never fixed that for versions. Still,
- it will save you backup time.
