Add a spare to that thing and replace the drive if possible or just add another to it to see if it goes away. PS you wont be able to remove it but you will be able to offline it if you have enough replicas. Mirror this vdev as you can not raidzN a log device. for instance: zpool add topool log mirror ad0 ad1 mirror ad2 ad3 And don't forget! A raidz group with N disks of size X with P parity disks can hold approximately (N-P)*X bytes and can withstand P device(s) failing before data integrity is compromised. The minimum number of devices in a raidz group is one more than the number of parity disks. The recommended number is between 3 and 9 to help increase performance. Regards, -- jhell,v
