Replacing a failed drive in ZFS on FreeBSD

1 Comment / Disks, FreeBSD, Open Source, ZFS / By /

I’m using FreeBSD 10.2-RC2. One of my new hard 3TB drives was acting up. I removed it and sent it off to be replaced. In the meantime, I received some 5TB drives and I added one of them into the existing vdev of the zpool. First, I partitioned the drive much like the other drives in the system. In my case, this was: $ sudo gpart create -s gpt da0 da0 created $

Adding two new drives (SSD) to an existing ZFS system

Leave a Comment / Disks, FreeBSD, hardware, Open Source, ZFS / By /

I haven’t tested this yet, but I’ve installed the hardware. The real test will come after a reboot and actual use of the new drives. NOTE: Although this claims to be creating a new ZIL (SLOG) do not believe it. In fact, stop reading right here. There is nothing of use below. What will they be used for? These drives are intended for ZIL (the ZFS Intent Log). This can speed up writes.
