run disklabel on the softraid disk, use 'b' to change the area.

resize crypto raid

[Uwe Werler]

Hello list,

is it currently possible to resize/increase a crypto raid anyhow? I tested it
with a virtual disk image via vnconfig - created an image file, attached it
via vnconfig, created a raid partition and configured a raid with crypto
discipline. Later I increased the image and adopted the partitoin size at the
vnd image. Softraid starts properly but still with the old size - disk
boundaries didn't change too.

Background: I think about full disk encryption for my virtual machine. In the
hindsight maybe that I let the disk size increase by my cloud provider.

Any hints? Any ideas?

Thanks in advance!

Regards Uwe

Hello Uwe,

IIRC softraid0 also saves disk size as a part of its metadata. I'm not
sure if metadata gets updated when you change just partition/disklabel
size, but I would not expect it.

Hello Ted,

this is exactly my problem - i can't change the disk boundaries at the
softraid disk. I tried it with saving the disklabel of softraid0/sd0 and
editing manually - with no success. Any ideas?
