Re: RaidFrame + Adaptec in -current [Was: Re: test request]

[Thierry Deval <TDeval@PrimeOBJ.COM>]

Hi,

It seems I should provide some more information concerning my problems
with -current Adaptec+RaidFrame.

So, I've attached my RAID configuration file and the corresponding
disklabels.
(
Just in case someone asks, the partition 'd' on the RAID which starts
at sector 0 is not giving any trouble. It always worked fine
before. Moreover, I did all my tests on the partition 'f'.
)


Then, let's try to better describe our problem here.

If I boot with my RaidFrame enabled kernel (whether in single user, or
without configuring the RAID), I can work normally on my non-RAID boot
SCSI disk.

But, when I enable the RAID and mount one of its partitions, it happens
that some operations lock completely the RAID disk accesses.
Sometimes it happens with reads on large files (like a 'tar tvzf ...'),
sometimes it's occuring during write accesses (a 'tar xvzf ...').
I also observed that when dealing with small files (like a 'vi test'),
this would often succeed.

That said, I should add that other processes not accessing the locked
drive (the same RAID set) still run unaffected (though I saw some
performance drain ???). I get no kernel panic.

If I then ask for a reboot, the halt sequence stops at the 'syncing
disks...' stage. I then have to do a manual reset.

Strange, isn't it ?
