Hi,
context is 12-stable, zfs, bhyve
I have a zvol-backed bhyve guest. Its zvol size was initially 512GB
It needed to be expanded to 4TB. That worked fine.
The problem is the freebsd guest is UFS and I can't seem to make it see
the new size. But zfs list -o size on the host shows that as far as zfs is
concerned, it's 4TB
On the guest, I've tried running growfs / but it says requested size is
the same as the size it already is (508GB)
gpart show on the guest has the following
# gpart show
=> 63 4294967232 vtbd0 MBR (4.0T)
63 1 - free - (512B)
64 4294967216 1 freebsd [active] (2.0T)
4294967280 15 - free - (7.5K)
=> 0 4294967216 vtbd0s1 BSD (2.0T)
0 1065353216 1 freebsd-ufs (508G)
1065353216 8388544 2 freebsd-swap (4.0G)
1073741760 3221225456 - free - (1.5T)
I'm not understanding the double output, or why growfs hasn't worked on
the guest ufs. Can anyone help please?
Given the above, the freebsd-ufs partition can't grow because there is a
freebsd-swap partition between it and the free space you've added at the
end of the volume.
You'd need to delete the swap partition (or otherwise move it to the end of
the partition on the volume) before you could successfully growfs the
freebsd-ufs partition.
Cheers,
Paul.
