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,
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'.
Hello Manas
The host runs ZFS on FreeBSD-10.2-STABLE. The FreeBSD guests (10.2 and
11-) run UFS. The Linux guests run Ubuntu 14.04-server on ext4. All
the guest disks were created using truncate. Thanks for the links,
it's what I was looking for.
