Hi, How do I make growfs actually grow a gvinum disk on FreeBSD 5.3? I've read the man pages, the Handbook, and done some searching with no luck. To help understand what I'm trying to accomplish here, I've created a filesystem that mounts to /export on a gvinum volume. The volume is configured as a mirror. I want to double it's size. To do this I used gvinum to add a subdisk to each plex of the mirror (this worked fine). gvinum now reports the volume as 32GB (it used to be 16GB). The filesystem is still 16GB. When I unmount the filesystem and run growfs on the device it claims there is no space to grow: # growfs -s 33554432 /dev/gvinum/export growfs: we are not growing (8388608 -> 8388608) And yet # disklabel /dev/gvinum/export # /dev/gvinum/export: 3 partitions: # size offset fstype [fsize bsize bps/cpg] a: 33554432 0 4.2BSD 2048 16384 0 b: 33554432 0 swap c: 33554432 0 unused 0 0 # "raw" part, don't edit disklabel: partition c doesn't cover the whole unit! disklabel: An incorrect partition c may cause problems for standard system utilities better still: # gvinum list 2 drives: D a State: up /dev/ad1s1g A: 58662/108326 MB (54%) D b State: up /dev/ad0s1g A: 58662/108326 MB (54%) 5 volumes: ...
