One of the great features of ZFS is to be able to expand it using new, larger disks — even while it is online. To do this you’ll replace each disk, one by one with a larger disk. After each replacement you’ll rebuild the zpool, and then move on to the next disk. Once all… Read more »
Debian 8 Under Bhyve Networking Problem: Packets Over 230 Bytes Truncated
Tuesday, February 13, 2018
We’re a big fan of FreeBSD’s Bhyve hypervisor, including writing an open source lightweight management interface for it called BMT.
