You need a partition of type 'vinum'. From the man page: DRIVE LAYOUT CONSIDERATIONS vinum drives are currently BSD disk partitions. They must be of type vinum in order to avoid overwriting data used for other purposes. Use disklabel -e to edit a partition type definition. The following display shows a typical partition layout as shown by disklabel: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 81920 344064 4.2BSD 0 0 0 # (Cyl. 240*- 297*) b: 262144 81920 swap # (Cyl. 57*- 240*) c: 4226725 0 unused 0 0 # (Cyl. 0 - 2955*) e: 81920 0 4.2BSD 0 0 0 # (Cyl. 0 - 57*) f: 1900000 425984 4.2BSD 0 0 0 # (Cyl. 297*- 1626*) g: 1900741 2325984 vinum 0 0 0 # (Cyl. 1626*- 2955*) In this example, partition g may be used as a vinum partition. Parti- tions a, e and f may be used as UFS file systems or ccd partitions. Par- tition b is a swap partition, and partition c represents the whole disk and should not be used for any other purpose. > This works OK every now and then. That surprises me. > Very often the server crashes! If you have a crash, please supply the information I ask for in the man page: Reporting problems with Vinum If you find any bugs in vinum, please report them to Greg Lehey <grog@lemis.com>. Supply the following information: o The output of the vinum list command. o Any messages printed in /var/log/messages. All such messages will be identified by the text vinum at the beginning. o If you have a panic, a stack trace as described above. You can get more detail at http://www.lemis.com/vinum/how-to-debug.html. > Of course, the resulting volume is too small to be useful. The output of 'vinum list' would be interesting here. > 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! I'd like to see the dump. It looks like your disk layout is hosed, but it shouldn't cause a panic.
