It should be added that any hardware problem should be replaced immediately unless it's a test system.
Electromechanical devices such as drives should be replaced as part of periodic maintenance not as corrective maintenance. If there are failures in production systems, then the PM schedule should be updated. Here the 3 year rule seems to work for drives. Especially laptop drives. They tend to run hotter. tedc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of ted creedon Sent: Friday, September 08, 2006 10:26 AM To: 'Kevin'; [email protected] Subject: RE: [OpenAFS] Should I replace a hard drive with known bad blocks?

Hi list- I realize that various filesystem tools (ext2, ext3, etc.) have utilities to map bad blocks and avoid having the system use them, but is it a good rule of thumb that a HDD with bad blocks is failing? ie, that finding bad blocks is an indicator that the HDD will soon fail catastrophically? I'm considering installing an OpenAFS server on a machine with such a hard drive. I've done about 20-40 passes on the partitions searching for bad blocks, and I do find them, but the number remains the same on each pass. So the question is one of judgment. Do list members think it would be advisable to replace a hard drive at the first indication that there are bad blocks (in anticipation of it failing soon)? If that is overkill, is it a bad idea to use a hard drive in production use where data integrity is important and the hard drive is known to have bad blocks? Or is it perfectly safe if some precautions are followed (such as scanning for bad blocks periodically henceforth)? Or other? Thanks for any feedback. -Kevin _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
