I'm using a BusLogic SCSI adapter, and am using Raid 1 with a 2.0.31-pre10
kernel. Lately, when running a high-volume mail application that our
company has developed, the machine hangs. While I'm looking into
MTA-related solutions, I would like to know if anyone has experienced
similar conditions with their SCSI+Raid setups.
Our system config:
Linux 2.0.31-pre10 (RH 4.2)
raidtools 0.42 with raid145
md driver 0.36.3
1 Ultra Wide PCI SCSI adapter (see below)
2 4.3GB SCSI HDs
1 SCSI CD-ROM
Below I include an excerpt from dmesg that contains the SCSI and Raid
info. I've noticed that the BT-958 SCSI adapter has been of recent
discourse; I am looking into those messages on these mailing lists. If
anyone could offer testimony to similar problems, I would greatly
appreciate a response:
