Hello John,

-   Do you use virtio-blk (a file created with 'truncate') or ahci-hd (A
ZFS filesystem, for example) for your guest disk? You have to increase
the space of the virtual disk that bhyve uses.
- If you used 'truncate', my guess is that you can use truncate to
create a new file of larger size. Then, boot into a livecd in bhyve with
both disks and do a 'dd' from one disk to the other. I have tried to
'dd' between files on the host but that didn't seem to work.
- If it is a ZFS filesystem, create a new filesystem with 'zfs create
-V 50gb zroot/new-volume/' then use a 'zfs send ... | zfs receive ...'

-   Are these FreeBSD guests (and which filesystem - UFS or ZFS) or Linux
guests?
- If these are FreeBSD guests running UFS, look at
https://www.freebsd.org/doc/handbook/disks-growing.html
- If these are FreeBSD guests running ZFS, you can probably create the
filesystems on your new disk and then use zfs send & receive
- If these are linux guests, you will have to use a livecd and
something like 'gpart'.

Thanks,
Manas

for virtualized instances that use UFS i have used growfs with success.
 what is backing your vm image?  if it is zfs you can most likely grow
the filesystem where your vm image lives then use growfs (if ufs) in the VM.

hope this helps,

adding diskspace to a bhyve instance

[John]

Hello list,

What's the best way of increasing the space of a bhyve guest instance?
Would it be via growfs? Inside or outside of the vm? Or would it be
better to truncate another chunk of space and refer to it in /etc/fstab?

thanks,
