HBA mode is perfect for mdadm, btrfs, zfs, and other software raid/raid-like things when using consumer grade drives.
But is the kernels RAID code any more tolerant of waiting for a minute or so for a drive to respond before declaring it dead than RAID cards?
I guess at least with software solutions you can hack it to be so..
yep. that's the point :) hard-coded vs hackable or s/w tunable. leave it up to the software to decide. of course, that implies that the short timeouts on enterprise drives are preferable to the long timeouts on consumer drives because that allows the kernel to decide how many times / how long to retry for. craig -- craig sanders <cas@taz.net.au>
