It's a combo USB/FireWire cabinet with two disks that can be combined into one RAID 0 or RAID 1 disk. I am using RAID 1. I've got it plugged into an Adaptec AFW-4300 PCI firewire card (FireConnect 4300, 3 ports). The Adaptec card shows up as: fwohci0@pci0:13:0: class=0x0c0010 card=0x801015c5 chip=0x8020104c rev=0x00 hdr=0x00 vendor = 'Texas Instruments (TI)' device = 'TSB12LV26 OHCI-Lynx PCI IEEE 1394 Host Controller' class = serial bus subclass = FireWire The disk comes up as: da0 at sbp0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-4 device da0: 50.000MB/s transfers da0: 476889MB (976670718 512 byte sectors: 255H 63S/T 60794C) When I try to write to the disk, I get around 8.3 MB/sec transfer rate: # dd if=/dev/zero bs=64k of=./filler.dat count=163840 163840+0 records in 163840+0 records out 10737418240 bytes transferred in 1223.276930 secs (8777586 bytes/sec) Reading the same file gives me around double that speed. Any kind of write operation results in a lot of these messages in /var/log/messages: Nov 6 19:47:33 pisces kernel: sbp0:0:0 Obj: Data buffer, Error: Time-out error Nov 6 19:47:33 pisces kernel: sbp0:0:0 sbp_scsi_status: unknown scsi status 0x0 Nov 6 19:47:33 pisces kernel: sbp0:0:0 Obj: Data buffer, Error: Time-out error Nov 6 19:47:33 pisces kernel: sbp0:0:0 sbp_scsi_status: unknown scsi status 0x0 Read operations does not give me these errors. Should I be worried about them? Apart from my worry that I will not be able to see if a disk in this cabinet goes broken, the syslog messages are quite annoying. :) Cheers, -- Anders.
