Hello! I'm running a fresh load of FreeBSD 4.0. I've got 10 SCSI disks running on an Adaptec 39160 which appear to work fine with file systems. I remove the file systems from fstab and reboot. All the labels look like this: # /dev/rda0c: type: SCSI disk: da0s1 label: flags: bytes/sector: 512 sectors/track: 51 tracks/cylinder: 166 sectors/cylinder: 8466 cylinders: 2118 sectors/unit: 17938986 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 17938986 0 unused 0 0 # (Cyl. 0 - 2118*) e: 17938986 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 2118*) I start vinum with "kldload vinum" and issue the following command: vinum "create -f striping" where "striping" is the following: drive d0 device /dev/da0e drive d1 device /dev/da1e drive d2 device /dev/da2e drive d3 device /dev/da3e drive d4 device /dev/da4e drive d5 device /dev/da5e drive d6 device /dev/da6e drive d7 device /dev/da7e drive d8 device /dev/da8e drive d9 device /dev/da9e volume raid plex org striped 512k sd length 0 drive d0 sd length 0 drive d1 sd length 0 drive d2 sd length 0 drive d3 sd length 0 drive d4 sd length 0 drive d5 sd length 0 drive d6 sd length 0 drive d7 sd length 0 drive d8 sd length 0 drive d9 If I understand the docs, this should use the entire disk. Unfortunately, the resulting volume is of size 0! So I try to create with the following: drive d0 device /dev/da0e drive d1 device /dev/da1e drive d2 device /dev/da2e drive d3 device /dev/da3e drive d4 device /dev/da4e drive d5 device /dev/da5e drive d6 device /dev/da6e drive d7 device /dev/da7e drive d8 device /dev/da8e drive d9 device /dev/da9e volume raid plex org striped 512k sd length 512k drive d0 sd length 512k drive d1 sd length 512k drive d2 sd length 512k drive d3 sd length 512k drive d4 sd length 512k drive d5 sd length 512k drive d6 sd length 512k drive d7 sd length 512k drive d8 sd length 512k drive d9 This works OK every now and then. Very often the server crashes! Of course, the resulting volume is too small to be useful. As a test I run "vinum resetconfig" followed by "vinum create -f striping" again. This time the server crashes. It's the exact same config file! Am I doing something wrong? I've got to believe that there is something wrong with my procedure or my machine because it is *really* unstable and doesn't appear to operate as advertised. Any ideas / help would be appreciated!
