I just replaced my USB and everything was going well until I rebooted.  After rebooting, my cache drive (500gb SSD) has become an unassigned device.  However, even when I stop the array, I can't find the cache pool in Main.  When I click on Add Pool and try to add a cache pool, I get an error (Invalid pool name - do not use user share names) evidently a conflict.  I look in /mnt and cache does not exist.  I start the array and look in shares, no cache or appdata shares.  Searching through the syslog I see cache_dirs being established, but an error stating that included directory 'appdata' does not exist.

 

As a result, my Docker does not start, but if the cache and appdata shares don't load, that's why...

 

I've looked through the forums and can't find a problem like this.  Help me Obiwan! 

 

Thanks in advance!

I've not seen any posts in the forum that sound like this...

 

Additional info...

If I look in the config/shares directory of the flash drive (/mnt/flash share on the server), I see the cache.cfg and the appdata.cfg

You seem to have at some point created a User Share called 'Cache' which is the cause of your problem and is why the system will not let you create a pool called 'Cache'.    The cache.cfg file you posted is that for a User Share - not that for a pool.  Since this share does not exist on any drive at the moment you can delete the config/shares/cache.cfg file from the flash drive and then the system would let you create a pool called cache.

Thanks!  That solved both the cache drive AND the Docker issue.  Much appreciated...
