If you had failures and it properly handled them, then you can
contribute to the good combinations, so far that's the list

I agree with Doug: nothing prevents you from using md above very slow

OK, these you don't get to count. If you run raid over USB...well...you

SATA is much better, but USB was never anything other than a means to

Has anybody used the RocketRAID 2220 to build hardware
raid and lived through failures?
As some of you may know from my previous posts, I've been
having problems with software raid. Unfortunately, this was
the only card available to me to add to my server so I
haven't been able to test anything

That is exactly what I miss.

I've been asking on my other posts but haven't seen
a direct reply to this question:
Can MD implement timeouts so that it detects problems when
drivers don't come back?
For me this year shall be known as the year the array
stood still (bad scifi reference :-)
After 4 different array failures

I have a need to kick a disk out of a RAID 5 array.
I can do a fdisk on 2 out of the 3 devices that form part
of the array, so I suspect I know which one is bad.
The problem is that mdstat shows the array as follows:
md3 : active raid5 sda6[0] sdc6[2] sdb6[1]
960863488 blocks level 5, 64k
Over the past several months I have encountered 3
cases where the software RAID didn't work in keeping
the servers up and running.
In all cases, the failure has been on a single drive,
yet the whole md device and server become unresponsive.

OK, lets see if I can understand how a disk gets flagged

that any read or write operation failure flags the drive as
bad and it gets removed
where the array is never degraded. Does an error of type:
end_request: I/O error, dev sdb, sector
not count as a read/write error?
Thanks,
