Hi, I'm fairly new to FreeNAS but v8.0.2 has run successfully for a couple of months. I have one ZFS-1 pool created using 5 x 2Tb disks and one of these recently failed. I followed the instructions for replacing the drive and it finished resilvering after two days. So far, so good. However, when I tried the command: zpool detach Array /dev/ada1/old, I got the reply: No such device. I then went to the GUI and tried to auto-import the volume which returned an error message and my whole pool/volume disappeared.
Back to the console, I tried a zpool status and that said "no pools available", while zpool import shows a degraded set of disks but says that the pool can be imported. zpool import Array (the pool name is Array) rattles the disk drives for a while and then says: "failed to create mountpoint" and after that zpool import returns nothing until after a reboot. I have tried mkdir /mnt/Array both before and after the import but it makes no difference.
Have I completely destroyed my volume or am I doing something wrong. Any help would be much appreciated and avoid losing 7Tb of data (fortunately just inconvenient; not critical).
