The best way to do a test is just to pull the power on one of the drives in the array. It's best not to pull the cable off as it might send a spike back to the IDE card and do some damage. If your doing mirroring then you'll be using RAID 1. Check your swap partition. If your swap partition is on the drive you are about to pull out and the swap is not on a RAID partition then your kernel will/may hang if there was memory swapped out to it. I have setup my swap on both drives but not as a RAID partition. If one drive dies the system will crash but after a reboot my system will just boot off the working drive as I have put the kernel in the Master Boot Record on both Drives. At least I won't loose any data:-) Steve McPherson wrote: > David, > I'm having some trouble with my raid, and I'm hoping you're willing to help me >out. > I'm using RH 6.0 with the 2.2.5-15 kernel with raid 0 and 5 and multiple devices >driver support and autodetect RAID partitions compiled in.
