Re: [HACKERS] SCSI Error
the hardware. On the other hand I do believe I saw a message recently saying that some of the 2.4 series kernels had file system bugs. I recall problems, offhand, with 2.4.5, 2.4.10, 2.4.11 (which was so broken that you couldn't recover), and 2.4.15. I seem to recall a report on 2.4.12, also. There's a page at http://www.atnf.csiro.au/people/rgooch/linux/docs/kernel-newsflash.html that provides some summaries of known problems, and filesystem corruption doesn't show up for all the ones I mentioned, so maybe my memory is faulty (alas, I didn't get the ECC option).

Back up immediately, if you haven't already got decent backups, and fix the disk/controller. Could possibly be a filesystem error but even if so it's still casting doubt on the hardware. On the other hand I do believe I saw a message recently saying that some of the 2.4 series kernels had file system bugs. I don't know which, someone else might be able to expand. -- Nigel J.

Re: [HACKERS] SCSI Error
Ensure you don't have termination issues. Make sure your SCSI interface is configured correctly for your SCSI environment, especially on matters of termination. Make sure you have enough power to your drive and if possible, make sure your drives are hung off of distinct power segments coming from your power supply. Of course, make sure you have enough power being supplied from your power supply to power all of your drives and *equipment* (cards, CPU, fans, etc). Last, be sure your cables are in good working order and that they are as far away from the power supply and cables as is possible. SCSI is notorious for suffering from RF interference especially on long cables. If all else fails, you may try swapping cables to see if this helps. If at all possible, immediately fsck (don't make it perform any repairs) and backup! The fsck will let you know if you should reasonably expect to have a meaningful backup. Requesting fsck to repair in this situation could actually result in more/worse (unrecoverable) corruption. If the fsck does report potential FS damage, accept the fact that some of your data (and resulting backup) may be corrupt, perhaps even unrecoverably so. I'm using a 7880 here and have never had notable issues save only for bugs in the Linux SCSI drivers. Greg On Fri, 2002-09-20 at 07:08, Ricardo Fogliati wrote: Hiya Lists Somebody could help me?
