I can't find any mention of 'size' in vinum_history. I overlooked this
in /var/log/messages:
Jul 24 15:42:51 cyrus /kernel: vinum: raid10.p0 must have equal sized subdisks
Jul 24 15:42:51 cyrus /kernel: vinum: raid10.p0 must have equal sized subdisks
I could well be the one to blame here. I presumed that vinum would
automatically set the subdisk length to the size of the smallest disk in
a striped plex. Is this correct?
Cheers,
