Hi,
I tried 6.0-BETA on one of our FUJITSU-SIEMENS RX300 S2 servers and
it seems that I have problems with the disk subsystem, even after
Scotts major overhaul of the mpt drivers...
I'm not able to post detailed dmesg output in the moment (IMHO there
isn't anything to notice, mpt0 and mpt1 are attached without any
errors) but the symtoms are:
- - very slow write performace: 'dd if=/dev/zero of=/dev/da0s2 bs=512
count=32768' reports a throughput of 80 k(!)Bytes/s. Read performance
is somewhat better, 'dd' reports here about 2 MB/s... better, but not
what I would expect from a RAID1 with two U320 SCSI-disks (Seagate BTW).
- - 'gvinum' has its problems too with this RAID Volume: I *can* create
a gvinum-drive on /dev/da0s2, but it remains 'down'. I can't 'start'
it and after a reboot, the gvinum-drive has gone and gvinum is
absolutely clean again.
This seems not to be a problem of gvinum, as it works perfectly under
6.0-BETA on my personal machine (Athlon-XP 2000, ahc-controller,
FUJITSU SCSI disk).
Still to mention: The RX300 has two Xeon CPUs and 2Gig RAM. It runs
with a stripped down kernel, based on GENERIC *without* all that
WITTNESS and INVARIANTS stuff. /etc/malloc.conf is linked to 'aj' -
that's all that I know of debugging options in CURRENT kernels...
The questions I have:
The LSI 1040 RAID-Controller is absolutely new to me, I did configure
a RAID1 Volume, synchronized it and that's all. Is there anything to
tweak besides the default config of that controller?
What additional informations do you need? I should be able to supply
them on monday... But there's not too much time to test, this machine
should become a Windoze printserver in about two or three weeks...
It seems to me that the HP DL380 is still the better machine... :-/
