Then the HOWTO should be updated. It says "Autostarted devices are also automatically stopped at shutdown". To me, this implies that devices that were not autostarted are not automatically stopped at shutdown. Hence, my concerns. Greetings Marc -- -- !!

Re: Corrupted filesystem on RAID-5 volume
I have a fileserver with two, 8-disk RAID-5 volumes, both of which appear to be corrupted. Linux kernel 2.2.12, raid0145-19990824-2.2.11 patch, raidtools-0.90. I could use some help reviving my filesystems, if that's possible. [ ... ] My disks are back on-line. It turns out that I had originally made a typo when entering the alternate superblock number for e2fsck. - C

Gerrish, Robert [EMAIL PROTECTED] wrote: backups can save your business. You not only should think about system failures, but fires, floods, etc. and silent data corruption. Remember, IDE hasn't parity. Also, disk-drives can develop bad blocks over time. That's why incremental backups, even done on your old QIC-120 for only the most important files, can be good.
SMP and RAID-5
Any known issues with running software raid-5 under kernel 2.2.xx on an SMP system? Specifically, I have a Gigabyte 6BXD with 2 (matched) PII-350's. I am going to run a SYMBIOS (Tekram 390F) 53C875 UW controller with 3 Seagate ST39140W drives in a RAID-5 config. Anyone know of any issues with this config... I thought I had read that RAID-5 had some issues in SMP systems... Cheers! Chris

Since upgrading to 2.2.13pre12 on a client's HP Netserver LXe Pro with dual Pentium Pro/200 CPUs, that was up 48 days straight running a Software-Root RAID5 across 4 drives until a recent power outage caused me to have to take it down. The SCSI adapter is an onboard AIC-7880, FWIW. Works like a champ! ::: Jason A.

adding a new architecture
Does anyone have experience adding a new architecture(such as even-odd, raid5+paritylogging) to linux raid? I think I can learn from your experience.Please describe what I should do to realize a new raid architecture.

While I'll be the last person to praise IDE, recent drives and controllers have CRC error checking, which is actually better than parity.
