- I am a novice system manager and in charge of two decstation of
- my advisor's lab. I don't know what the problem is,
- not to mention how to solve it. The tape is ok since I used it to backup
- other filesystems later, it worked just fine. I tried the dump procedure
- several time, the error messages were the same except the block number of
- the Disk read error line. Fsck didn't find any problem in the disk.
- Could some help me out? If it is a disk problem, how can I identify the
- bad block and fix it?
-
- Thanks a lot.
