Yeah but that's already a bit tedious. Also every time you add & remove
a disk for VVM view it reserves the device id which means additional

Actually my first live-and-learn experience with VVM was due to moving a
disk back and forth between servers (fast, easy and dangerous way to
move 4T of data); the id's got mixed, VVM reported "already initialized"
for all new devices etc. so I experimentally mkfs'ed the real device
instead of vx device. Result: Disaster in a file system that consisted
of two concatenated disks. Deceivingly it worked fine for two weeks
until vxconfigd restarted probably upon VEA installation.

Thus, I'm looking for a way to resize a file system without too much
hassle with temporary disks.

I haven't used it much, but someone else has already commented that the
dynamic resize requires additional disks in the disk group.  (That's
what the 'vxdisk resize' is.)

Presumably you could temporarily add a disk (could be tiny) to the
group, resize the storage LUN, then remove the temporary disk.  It would
just be acting as a holding place for the DG information while the LUN
is resized.
