for what its worth, I am using 2 firewire "encoders" with a local 7
drive raid5. I am using latest ATrpms on FC3. kernel 2.6.12 smp.
I have had no problems with simultaneous HD recordings (even starting
at the same time), and the performance seems to be better than my old
2 drive LVM configuration.
My system:
P4 3.2 (with HT)
1 G RAM
2 onboard SATA ports
3 ATA/133 cards with 2 channels each -- one drive per channel
6 x wd2500 (woot's 250 G drive)
2 x Hitachi SATA 250 G
2 x on-board Firewire capture
6 ATA and 1 SATA make the raid5, and the other SATA is root. /dev/md0
is formatted XFS for 1.45 TB
The only RAID problem I had was one of the WD drives dropped off, not
bad, just needed a reset. The system hung twice during the subsequent
rebuilds. Added the drive back, and its all happy now.
No recording problems at all. I actually stopped getting glitches in
my HD records (part due to better RAID performance, part due to no
longer running commercial detection)
