Replacing a failed drive in ZFS on FreeBSD
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
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.

ZFS: raidz2 with 8 or 10 disks?
The traditional thoughts on ZFS are to have arrays which are a power-of-2 when it comes to number of disks. That means 2, 4, 8, etc. But for raidz1, that would be 3, 5, 9. For my choice of raidz2, it would be 4, 6, and 10. In the system I’m building up now, I have an 8-port LSI SATA/SAS 9211-8i 6Gb/s card. I can add two more HDD by attaching them to

smartctl: FAILING_NOW
I noticed this in my logs today: May 22 14:04:39 bast smartd[1577]: Device: /dev/ad0, Failed SMART usage Attribute: 9 Power_On_Hours. Oh. Really? I looked at the output of smartctl and found: This HDD is part of a gmirror: $ gmirror status Name Status Components mirror/gm0 COMPLETE ad0 ad2 How’s ad2 doing? That seems OK. Regardless of the status, I can do nothing for a week. I’m out of town. I do have several
