Hi All, I currently have a couple of IT8212 PCI ATA RAID (1, 0 ot 1+0) cards which Linux RAID doesn't seem to like too well. Initially I tried creating an array out of 4 disks on the 4 primaries over the 2 cards. Although this seemed to work, the access performance was impossibly low and I never actually got to the point of leaving it for a week to build the array.
Since then, I have striped 2 of the drives (just primaries again and known to be good drives) on a single card using the cards own striping capability. This striped drive, I've that added to my RAID 5 array as a 500GB single disk. The grow into this disk worked fine as did the resize2fs. As soon as I tried to copy data onto the array, the system marked the disk as faulty. Now currently I'm running a degraded array anyway as I'm waiting for the replacement of the drive that failed with bad sectors when I initially started the grow. So I had to use assemble --force to get the md device back online. I've not mounted it since. (I know it's wise not to use the drive while it's degraded, but if I can get the data off of a 320GB HD, then I can stripe that with another disk on the other ITE card, and add in a spare to the array). Can anyone see any issues with what I'm trying to do? Are there any known issues with IT8212 cards (They worked as straight disks on linux fine)? Is anyone using an array with disks on PCI interface cards? Is there an issue with mixing motherboard interfaces and PCI card based ones? Does anyone recommend any inexpensive (probably SATA-II) PCI interface cards? The motherboard has run out of sensible interfaces (I'm not using both primary and secondary in an array on IDE), but I'd still like the capacity to grow my array further. Thanks again for the help.
