Hi folks,

I'm a bit puzzled by raidframe on 1.5/i386 failing one of our
raid0 components with the following messages:

Feb 26 07:05:55 mail /netbsd: raid0: IO Error.  Marking /dev/sd1e as failed.
Feb 26 07:05:55 mail /netbsd: raid0: node (Wsd) returned fail, rolling forward

however.. this was about all there was to it, none of the loud and
rather verbose scsi error messages I have seen on other disk failures
(in non-raid setups, though).
I am therefore wondering if it might be some false alarm? (the disk
seems to be working after reconstruction, I've had this incident once
before and the disk worked nicely until this second time.)
How come the raidframe driver detects an I/O error and the scsi subsystem
of the kernel doesn't scream multiline scsi-error messages at me (I have
SCSIVERBOSE defined in the kernel config)?
Does anybody here have experience with disks failing under raidframe
and could enlighten the situation a little bit for me?
