I had a drive in my primary stoarge pool fail this week, and have ordered a replacement. I found that the BTRFS pool was not mounting automatically at boot time. Following the wiki i was able to get the pool mounted in degraded mode. But docker will still not mount the rockon share. Is there anything I can do to get the share mounted while I wait for the replacement drive to get here? I also noticed the Rockstor Web UI is not detecting any of the shares on the pool.
