I see there has been some discussion of firewire problems in the list archives but I can't find any real resolution or current status. I'm trying to do online backups with backuppc to a software raid set consisting of one partition on an internal IDE and one on an external firewire drive, then periodically rotate the external disk offsite and re-sync to a different one. The raid activity is generally irrelevant to the problems I have had except that since the external drive isn't detected during the boot sequence any reboot starts the raid in degraded mode and requires a full re-sync (7 to 8 hours for 250 gigs...) to restore the mirror This has been tolerable so far because the filesystem can be used anyway. I have been able to use the drive only under the following circumstances: running FC1 (currently kernel 2.4.22-1.2199.nptl) manually modprobe ohci1394 and sbp2 echo "scsi add-single-device 0 0 0 0" > /proc/scsi/scsi It doesn't work with any of: A different brand of ie1394 card. A 'real' scsi device in the machine. FC2 (any kernel I've tried). Reconnecting a disk without rebooting. In most of the failure cases the drive shows up under /proc/bus/ieee1394/devices but not as a scsi device. I've tried a couple of the re-probe-scsi scripts I've found on the net with no luck. Any advice? --- Les Mikesell les@xxxxxxxxxxxxxxxx
