Lost a drive in ZFS

Posted on March 23, 2011 by Jono

I upgraded my storage machine to Open Indiana. Then after doing a zpool upgrade and a scrub I noticed a drive is marked as faulted. So far my data is still safe on three drives, but it makes me nervous to be running without a fourth drive. Will have to swap it out and resilver ASAP.

    Turns out one of my SATA cables had wiggled loose. After reconnecting the drive and running a scrub all is well.
