Volume Degraded (sometimes)

[ag1st]

Hey Guys,

I've had my FreeNAS setup for a few years now, but it's recently been claiming to have a degraded volume. When I check disks, one of my new disks is missing from the list. Then, when I restart the server, the disk is back. I get this problem every other week or so.

When I run a check in the shell (zpool status -v), it simply says that the drive is unavailable.

Any suggestions? Let me know if you need any more information. Because I'm doubting that the drive is really bad if it keeps popping back up, and the volume often says that it's healthy.

Thanks in advance!
