June 2, 201610 yr I've had this issue two days in a row. My shares all disappear randomly. When i ssh into unraid the /mnt/disk(1-6) are fine and the data is there, but the /mnt/user has 0 files and appears to have unmounted. In the diagnostics I see something about too many files open. My Diagnostics are too large to attach. Below is a sample of the syslog1.log where the error starts.

At that point everything is back to normal.
June 2, 201610 yr Post them to drop box and provide a link. Sight unseen your cache drive either dropped dead or has a cabling issue and dropped offline Sent from my LG-D852 using Tapatalk
June 2, 201610 yr Community Expert Not much useful in the part of the logs you gave us. What filesystem is on your cache?
June 2, 201610 yr Author Ok. I trimmed only the end out of the log, which was just repeating of the same error.
June 2, 201610 yr Community Expert How full is the cache drive? Do you think it may have ever run out of space? Maybe this wiki has something for you. Check_Disk_Filesystems: Drives_formatted_with_BTRFS
June 2, 201610 yr Author Actually, yes. At one point my cache drive was full. I copied off the data and freed up a lot of space. That was a few weeks ago before this error started happening. I'll have a look at the wiki here
June 3, 201610 yr Author I ended up copying everything off my cache and reformating to XFS. I'll see if this helps. thanks!
April 9, 20179 yr @razor I'm having the same problem with shares going missing. However, my cache drive isn't full when it happens. Changing to XFS on the cache drive help at all?

Changing to XFS on the cache drive help at all? There can be different reasons for things that seem to be the same problem. You should start your own thread and post diagnostics. Tools - Diagnostics, post complete zip. NVM I see you have your own thread.
May 2, 20179 yr Author Yes, reformatting to XFS has helped. I haven't had this issue since then. Edited May 2, 20179 yr by razor
