My FreeNAS 9.2-RELEASE-p3 (I assume this is 9.2.1 ?) has been running on a box with 4 x 1TB Hitachi Deskstar 7K1000 drives, vintage 2008 or so. I knew they probably didn't have a lot of life left, but they seemed ok to get my feet wet with a FreeBSD file and media server. Worked pretty well since November. I recently added a new 500GB drive to act as a backup, which I xfer data to using rsync. My ZFS volume/pool (still not sure which is correct) server is /mnt/FN-1TBMir, and I rsync everything below that directory to the backup drive. Not sure if its necessary, but better safe than sorry.
This morning I find an email stating that my drive array is running degraded. Referencing several posters in these forums I checked the Volumes and Disks, and ran the usually recommended shell commands:
zpool status -v
camcontrol devlist
gpart show
smartctl -q noserial -a /dev/adax (once for each drive in my system, from ada0 to ada4)
Sure enough, one of the old Deskstars had taken a dive. Reading more posts here concerning hardware selection, I chose to replace that drive with a WD RED 1TB WD10EFRX. As I stood in line at the store, I realized this was my opportunity to replace all 4 Hitachi's with current technology true-NAS-purposed drives to avoid another drive death in the near future, so I bought 4 1TB REDs. "In for a penny, in for a pound" as they say.
Before I start in on the replacement process, and being a noob with more courage than knowledge, could anyone here give me the Coles Notes version of the process for swapping out all the old drives and installing the new? As I said, I have a full backup from last night available, and the remaining 3 Deskstar drives are still functional, so other than replacing the dead drive first (I assume), what is the process for replacing each of the other drives? Just do the same thing as for the first drive x 3? In what order - dead drive, dead drive's mirror drive, then the other two mirrored (still good Hitachi's) in any order?
I know damn well that I dodged a bullet here, as prior to last week I hadn't done a full backup - I got lucky. So I'm a little twitchy about doing this wholesale drive swap-out - I don't want to squander a bit of good luck with bad procedure now.
Any suggestions? If you need more info, just ask and I'll post it. I did a quick search of posts about replacing drives, but all I found were about replacing 1 bad drive, or replacing drives without a backup. I'd feel more secure if someone could guide me in doing this right with the fewest assumptions possible. I have a knack for stumbling into the only pothole on a smooth road.
Thanks for any help. These forums have saved my butt more than once already!
