Hi, it seems that the cache drive is acting up. It is not moving the files from the cache drive even if the scheduler is on. I rebooted multiple times, ran manually the mover but when I look at the logs (attached), it looks like it try to move the file to the cache drive itself instead of moving it to the shares. Ex. moving "system" to cache

 

Any thoughts? As you can expect all my shares are shown as unprotected.

 

Thanks!

If a user share is configured with the "Use cache disk: Prefer" option it will do just as you describe. Since unRAID 6.2 that has been the default configuration for the system share. Turn on the webGUI help for more information.

Well the problem is not files going on the cache but why they are not transferred back to the share once the mover run?

Quoting the webGUI help that I mentioned above,

 

Specify whether new files and directories written on the share can be written onto the Cache disk/pool if present.

 

No prohibits new files and subdirectories from being written onto the Cache disk/pool.

 

Yes indicates that all new files and subdirectories should be written to the Cache disk/pool, provided enough free space exists on the Cache disk/pool. If there is insufficient space on the Cache disk/pool, then new files and directories are created on the array. When the mover is invoked, files and subdirectories are transferred off the Cache disk/pool and onto the array.

 

Only indicates that all new files and subdirectories must be writen to the Cache disk/pool. If there is insufficient free space on the Cache disk/pool, create operations will fail with out of space status.

 

Prefer indicates that all new files and subdirectories should be written to the Cache disk/pool, provided enough free space exists on the Cache disk/pool. If there is insufficient space on the Cache disk/pool, then new files and directories are created on the array. When the mover is invoked, files and subdirectories are transferred off the array and onto Cache disk/pool.

 

You need to set your Media and Backup shares to "Use cache disk: Yes" instead of "Use cache disk: Prefer".

 

I think that the Help does not mention that if you have the Use Cache disk set to 'No' it also prevents any files being moved to the array by mover if any files for a share are directly created on the cache disk by an application using a /mnt/cache type path.

Yes it should probably be added that mover ignores cache-no and cache-only shares.

 

It moves cache-yes from /mnt/cache to /mnt/user0 and moves cache-prefer from /mnt/user0 to /mnt/cache.
