I have a Highpoint RocketRAID 454 card configured for RAID5 with 4 discs
(driver is hpt374.ko) on FreeBSD 5.2.1-RELEASE. I have had a history of
panics that I think emanate from the filesystem and I have far more
physical failures of the discs than one might expect (I suspect heat damage
due to poor ventilation).
Having built myself a debug kernel I was able to pinpoint the following in
3 recent panics that occurred within a few days of each other. Around this
time I found that another disc has died on me.
In all cases I believe the panics occur under periods of intense disc
activity; e.g. copy many files from one area to another, or running big
meta-data updates like chmod -R and chgrp -R.
This the instruction that calls the panic:
#14 0xc0776904 in softdep_move_dependencies (oldbp=0xcd0d9c20,
newbp=0xcd0c0838) at ../../../ufs/ffs/ffs_softdep.c:800
800 panic("softdep_move_dependencies: need merge code");
I have read this post:

a) Is it reasonable to assume that my panics are exactly because I have
suffered physical disc problems/
b) shouldn't my external RAID5 have insulated me from such issues?
c) might there be some incompatibility with Soft Updates and this
particular RAID5 implementation?
I am happy to forego the benefits of SoftUpdates if I can then have a
stable machine.
What would you recommend?
