Had a SSD fail in an all flash array with 11 x 2TB SSD mirrors on FreeNAS 11.1-U2. The array froze up with high disk IO. Had this before when adding a new disk so I physically removed the failed drive and added a replacement then rebooted. IO issue fixed however now I have have one of my vdev in a non redundant single disk stripe. So to recreate the mirror I need to do a

zpool attach
. I ran the command zpool attach -f CROSSD <poolname> /dev/da2 <striped single vdev> /dev/da3 <new SSD to add to the mirror>
. Got the error back no such device in pool. I assume this is the right syntax - existing disk first followed by disk to be added? Anyway I thought maybe I needed to use gptid so I ran zpool attach -f CROSSD gptid/d4b12cb8-fa5e-11e6-bd35-00074336d800 /dev/da3
and got device is too small. They are both 2TB SSD, admittedly one is Samsung and one is SanDisk but is there a work around? Ive read two articles. One suggested I need to change the swap file for the array to 0, which I don't know what the effect will be so I'm hesitant and another that says I need to run gpart commands to create partitions on the new disk before I add it. Any have one have some ideas?FreeNAS 11.1-U2.
