I have a P3-800 with two IDE drives in a software RAID1 configuration.I tried software RAID1 with *. It worked well until we had to recover a drive. During drive recovery (recopy) the CPU is pegged, and it takes ~16 hours to recover the drive. I believe this is a Linux bug--there is no reason for such a high CPU usage during a disk copy. Note that any abnormal Linux shutdown will cause a drive recovery.
Each drive is on a separate IDE channel. Now anytime there is HD
activity, I hear "beeps" and "cutting out" on a call using the X100P
card.
I ran the zttest program, and discovered HD activity would drop the
accuracy down to between 2% and 50%.
However I noticed if I disabled one drive in the RAID1 array, zttest would always report 99.98% or higher. So one drive running works fine, but as soon as I enable the second drive, all hell breaks loose. DMA and 32-bit mode are enabled on both drives as well.
I have a backup server with two Promise PCI IDE controllers in it, with
4 drives in a software RAID5 configuration, so just out of curiosity
sake, I stuck a X100P card in it and tried running zttest while the RAID
was re-syncing. The results were pretty bad.
--- Results after 384 passes --- Best: 36.779785 -- Worst: 1.562500
Is this a poor mainboard issue, or is it actually not possible to do IDE software RAID on a machine running Asterisk with X100P cards?
Is anyone currently doing it?
Thanks.
I've since switched to 3Ware PCI RAID card. The driver is in the Linux distribution which makes it very easy to configure. The card is only about $100 US.
For a new client, I'm about to purchase a dual processor Athlon motherboard with an onboard RAID chip. Stay tuned.
