I've just committed a new version of Vinum with a large number of changes. It works fine here, much better than the old version, but there's just a possibility that things may go wrong. If you have trouble, please let me know immediately.
One way you can shoot yourself in the foot: the `read' command has changed. In the previous version, you specified the name of exactly one device containing a vinum partition. This is suboptimal, because it doesn't allow you to read multiple configurations, and it doesn't allow you to move drives around. In the new version, you *must* specify the names of *all* disks containing Vinum partitions. For example, if you have Vinum partitions /dev/da1h /dev/da2h /dev/da3h /dev/da4h /dev/da5h and /dev/da6h, you might previously have written: vinum read /dev/da3h Now you *must* write: vinum read /dev/da1 /dev/da2 /dev/da3 /dev/da4 /dev/da5 /dev/da6 If you do this wrong, you have the potential to wipe out your on-disk configuration. You can avoid this by disabling saving the configuration. Do this with the `setdaemon' command: # vinum vinum -> setdaemon 4 vinum -> read /dev/da1 /dev/da2 /dev/da3 /dev/da4 /dev/da5 /dev/da6 Yes, I know, specifying bits for the setdaemon command is tacky, and it'll go away. Bit 4 disables the configuration save. When your configuration is recognized correctly, you can re-enable it with `setdaemon 0'. For more information RTFM. The on-disk configuration has also changed. Previously, it contained the names of the drives as well as the other objects; now Vinum finds the drives by itself. You can check the versions by looking at the config copy at offset 9 blocks from the beginning of the partition: # dd if=/dev/da2h skip=9 count=1 volume obj state up volume src state up volume raid state up volume r state up volume S state up plex name obj.p0 state up org concat vol obj plex name obj.p1 state up org striped 128b vol obj plex name src.p0 state up org striped 128b vol src plex name src.p1 state up org concat vol src plex name raid.p0 state up org raid5 vol raid plex name r.p0 state up org raid5 vol r plex name S.p0 state up org raid5 vol S sd name obj.p0.s0 drive drive2 plex obj.p0 state up len 409600b driveoffset 265b plexof1+0 records in This version shows the new configuration: it starts with volume definitions. The old version starts with drive definitions. The new version will ignore any drive definitions it finds in the configuration.
