Unraid USBs keep failing

[007craft]

I really don't know what to do here.  I have 2 unraid servers, both get USB drive failures every 3 weeks - 2 months of use.  Ive switched out to 3 different brands and it just keeps happening.  At some point Unraid will stop responding, nothing will work and will be filled with errors.  If I can manage to pull up the web ui after some time, I see no flash detected and cant stop the array or shutdown properly.  I cant SSH in at all.

After reboot, everything works fine again, for 1-2 months again.  I'm at my wits end here and about to abandon using Unraid because of its unreliability.  Is there anything that can be done here?  Can I somehow run Unraid NOT on USB Flash Drive?

No

 

Perhaps post diagnostics so someone can see what is going on with your system

You can use a USB to mSATA or M.2 SATA adapter, but not all will work since Unraid reacquires a uniquie ID, IO can post links to models reported to work if you want one or the other.

Sometimes this happens when some Docker, Plugin or VM is using the Flash/Boot drive for storage--- Often this will be for temporary scratch files.  Have a good look through the directories for recent activity.    (Modern USB flash drives have very short lives if subjected to continuous write operations...)
