I have written an rc.d script growfs that is in HEAD that makes this painless... If you have a single UFS fs, w/ the root as the last partition/fs on the disk, simply grow the disk, and then you can run "service growfs start", and it just works... This will work on any system, not just VMs... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not." ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"

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. -- John ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
adding diskspace to a bhyve instance
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, -- John ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
