Hello,
I have a server which hangs due to disk activity. The output of the scsi
driver (captured over serial) is below the dmesg part of the scsi
detection and initialisation.
The kernel used is 2.6.10-mm2, but I also see it with 2.6.10-rc3-mm1
The system is a dual Opteron 250 with 8GB ram and 4x 15k rpm scsi disks.
The four disks are divided in two partitions, with raid1 ext2 for /boot
(read only), and raid10 reiser3 for /
(rw,sync,data=journal,barrier=flush).
The / is mounted 'sync' to be more sure the data hit the platters before
the systems crashed (due to tests etc). (btw, should I mount it 'sync',
or is 'barrier=flush' (almost) as save?).
The distribution is up to date Debian gcc3.4 (64bit only), and that is
also the OS used to compile kernels:
gcc (GCC) 3.4.4 20041218 (prerelease) (Debian 3.4.3-7.0.0.1.gcc4)
After the systems spits out the "Dump Card State Begins" messages, I
have to reboot to get it back.
Can this be hardware? If not, can I provide more info on this?
Thanks in advance.
Kind regards, Sander
