Something I have noticed with my Unraid setup is that upon reboot, it doesn't re-assign the cache drives.  This causes docker to not start (as it cannot find the file), so I have to stop the array, assign the cache drives, and start the array again.

 

I am running an AVS 10/4, all 10 3.5" bays are full, and in the 2.5" bays I have 2x 512Gb SSD. I am running Unraid 6.2.4

The two drives that don't get re-assigned are:

 

SanDisk_SD6SB2M512G1022I_144451401233 - 512 GB (sdc)  (Cache)

SanDisk_SD6SB2M512G1022I_144451401242 - 512 GB (sdg)  (Cache 2)

 

I have attached my system log to this post.

Here is a screen of my dashboard:

 

 

 

Please let me know if I can provide any additional information

Except for v6.3.0 the usual fix for this issue is to user another browser other than chrome, but you need to do the whole procedure with it, assign the caches devices, start array, stop array and reboot, then you can go back to chrome.

 

This issue is also a bug on v6.3.0 with any browser, fixed on v6.3.1, you should update in any case, but with v6.3.1 assignments might stick even with the current browser you're using.
