   More likely the disk rather than the controller – what sort of errors you get – timeouts?

   I suspect it’s the controller rather than the disk too, although the errors only appear when the disk is under heavy load, such as when running the AMANDA backups.

   Just as well I managed to persuade our supplier to send me a spare disk and controller “for evaluation”, I guess.

   it is all over the disk, or certain sectors, ie same sectors again and again?

   Certain sectors -> more likely disk

   all over -> more likely controller or cable.

   Of course it could be the PSU not handling the load…..

   One more thought

   I’ve got amanda 2.4.2p2 running on a Sunons 4.1.3 machine that seems to hang to thing when doing a full dump of all the filesystems more often than not.

   But there are a couple of known dodgy disks on the system, although I see nothing on the log files to indicate SCSI errors.

   The TCP/IP stack just locks solid….

   Just finishing up the job now – I’ve replaced the presumed-faulty disk with a new one. Fingers crossed …

   Oh, and I’ve ordered a new dedicated backup server for the backups.

   Modest tape drive, but holding area will be a 250GB disk … 🙂
