First, I'll go into the details.
SuSE 5.3 (or 5.2) distro,
Linux 2.0.36 (UP)
Tyan Tahoe II Dual Pro. LX mb
was - 2 PPro 200s on riser cards for slot 1
now - 2 P-II 266
256 meg memory
DPT SmartRaid V Millennium (w/ 3 SCSI bus and 256 meg cache)
4 gig IDE
8.4 gig IDE
4 9.1 gig Seagate Baracuda (in 26 gig Raid 5 array, SCSI bus 0)
4+1 50 gig Seagate Baracuda (in 146 gig Raid 5, SCSI bus 1, Hot
Spare)
2 50gig Seagate Baracuda (individual drives, SCSI bus 1, id 5,6)
DPT I2O driver (1.05 and 1.06??)
history:
This machine has been running for a while in UP with zero problems. I
wasn't aware it was UP (I keep forgetting to uncomment SMP = 1).
today:
Decided it was time for the upgrades I've been planning. First I tried
changing the kernel to 2.0.38 with the newest drivers from DPT patched in
(had to do it manually since the driver was for 2.0.36, but it was easy as
there were only about 4 or 5 files I had to touch). Compiled it with SMP
and booted. It came up SMP, went through and saw the DPT (loaded as a
module) card, saw the physicals, fsck reported all partitions clean, and
then it goes to Mounting local paritions. Only problem it just sits there.
The case's HD LED is connected to the DPT card. It showed blips every so
often, but nothing continuous. I've let it sit for 15 or 20 minutes
(probably longer) but it never progresses. Rebooting the machine still
indicates clean partitions, so they never were getting mounted.
If I go back to UP, it appears to work. The UP mounting partitions step
is reasonably fast (the first partition is reported within a few seconds).
The system hasn't been upgraded to 2.2 since it is an active server, and
today's downtime due to this upgrade is really hurting. The next step is
to upgrade to 2.2, but that will be a weekend when I can do a proper
backup and redo the partitions and then restore on a new system. Plus I
will have to validate a lot of custom programs to make sure they all work
on the new system -- that's why it is still at 2.0.
Anyone have any ideas or help? Is the DPT driver just not SMP capable in
2.0 kernels? Or is there something else going on I need to worry about.
Any assistance would be greatly appreciated, usually I figure these things
out on my own, but this one appears to be something really stupid and
simple that I've overlooked, or just plain impossible.
TIA,
Greg
