Originally posted on r/unraid but realized this is a better place. I stumbled on this today. Maybe someone here has seen this before? I found a way to get files stranded on a cache pool. My setup: 2 cache pools: One is named `app_data_cache` and it has a single share, `appdata` that has cache set to Prefer and assigned to the `app_data_cache` pool. One is named `cache` and has a share named `Backups` and has cache set to Yes and assigned to the `cache` pool. I was working with some Unraid files and I did the following commands: Check this folder and it does not have `Backups` in it: `root@Chonk:~# ls /mnt/app_data_cache/` `appdata/ system/` Checked to make sure no `hi.txt` exists: `root@Chonk:~# ls /mnt/user/Backups/hi.txt` `/bin/ls: cannot access '/mnt/user/Backups/hi.txt': No such file or directory` And no `/mnt/cache/Backups` `root@Chonk:~# ls /mnt/cache/Backups` `/bin/ls: cannot access '/mnt/cache/Backups': No such file or directory` Make a file: `root@Chonk:~# touch /mnt/user/appdata/hi.txt` File now exists: `root@Chonk:~# ls /mnt/app_data_cache/appdata/hi.txt ` `/mnt/app_data_cache/appdata/hi.txt` Move to another Share that happens to be on another cache pool: `root@Chonk:~# mv /mnt/user/appdata/hi.txt /mnt/user/Backups/` Verify it's no longer in the `app_data_cache/appdata` folder: `root@Chonk:~# ls /mnt/app_data_cache/appdata/hi.txt ` `/bin/ls: cannot access '/mnt/app_data_cache/appdata/hi.txt': No such file or directory` See that a `Backups` folder was now made on the wrong cache pool (should be the `cache` pool): `root@Chonk:~# ls /mnt/app_data_cache/` `Backups/ appdata/ system/` The `hi.txt` is on the wrong cache pool in the right directory: `root@Chonk:~# ls /mnt/app_data_cache/Backups/` `hi.txt` The right file always shows up in the right `/mnt/user/Backups` folder: `root@Chonk:~# ls /mnt/user/Backups/hi.txt ` `/mnt/user/Backups/hi.txt` The file does not exist on the right pool (verifying): `root@Chonk:~# ls /mnt/cache/Backups/` `/bin/ls: cannot access '/mnt/cache/Backups/': No such file or directory` If you can follow that series of commands, I create a hi.txt file and place it in the appdata folder, which lives on one cache pool. I then move that file over to my SwapSSD folder, which lives on another cache pool. The mv command is not moving the file to the other cache pool. Instead, it remains in the `app_data_cache`. When mover runs, it does not move this file to the array, I suspect because the named pool is wrong. when mover runs, with logging, I see this: Aug 26 13:53:04 Chonk move: file: /mnt/app_data_cache/Backups/hi.txt Aug 26 13:53:04 Chonk move: move_object: /mnt/app_data_cache/Backups/hi.txt File exists Upping the logging level to 2: Aug 26 13:54:39 Chonk move: debug: move: real_path: /mnt/app_data_cache/Backups/hi.txt Aug 26 13:54:40 Chonk move: file: /mnt/app_data_cache/Backups/hi.txt Aug 26 13:54:40 Chonk move: debug: create_parent: exclude 1 real_path /mnt/app_data_cache/Backups Aug 26 13:54:40 Chonk move: move_object: /mnt/app_data_cache/Backups/hi.txt File exists Aug 26 13:54:40 Chonk move: debug: move: real_path: /mnt/app_data_cache/Backups Aug 26 13:54:40 Chonk move: debug: move: move_object: /mnt/app_data_cache/Backups: Directory not empty At this time, I have no way to get the file off of the `app_data_cache` unless I manually move it to the other disk, so that mover can then do its thing. Is this a bug?
