Re: [expert] Suspected FS corruption bug
> does it happen with the 'kernel-linus' ? I recompiled my kernel last night from stock source code I downloaded last night. I'll let you know how it goes. So far no problems except wierd errors with VMWare's NT install. But that's most likely due to the fact that I transferred the entire VMWare disk to this machine over the internal network. I've fixed it now if I notice anything more I'll let you know. The suggestion about the memory is also possible I guess. Does linux have problems with ECC PC100 SDRAM? I've got a "ram exam" program I'll run on it to see if it turn's anything up.

OK I'll check the ram. However this machine was running fine for about 4 months until I put mandrake 7.0 on it. Never had any problems with this machine with mandrake 6.0 on it.

About 1 of every 10 PC100 SDRAMS we have received from our vendor have been bad. They would pass the short POST at power-on but hey raised hell after words in a number of subtle ways. regards palmer

If it doesn't repair or errors out of the fscks no matter what, your Hdd is due for that last ride If it repairs but immediately shows errors when you boot it or after two or three boots then perhaps there is a bug everyone wants to know about. However this is the most unlikely of the three since the routines that handle the filesystem are the nearly the oldest and certainly most stable of all and only the drivers are updated.

Re: [expert] Suspected FS corruption bug
That does not sound like anything but either a) memory or b) HDD. Most likely b. I just recovered a filesystem where a processor had done a HCF (Halt and catch fire) and the disk repaired itself beautifully.
