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... :-/ - -- Ciao/BSD - Matthias Matthias Schuendehuette , Berlin (Germany) PGP-Key at and ID: 0xDDFB0A5F -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) iD8DBQFC174af1BNcN37Cl8RAtvcAKCDwcuIA7XusCCX80N6b4LmN0JRKwCfbvA+ VSfudFkdO3UHmOqpVR18obU= =Vzw8 -----END PGP SIGNATURE-----
