Andrew,
I installed unRaid from scratch. No change. I switched cables no change. I deleted all references in Keychain relating to unRAID and its IP address. No change. I created a new user. No change. I have just burned out on unRAID.
Because I already had a license for NASLite (in use), I could buy another license of NASLite-M2 x64 for $22.72.
Within 2 hours, I had the software installed on a USB thumbdrive, formatted all my disks, and setup rsynch backups.
I created multiple streams of simple Finder copies to the NASLite. Photos. 3d projects. Substantial iTunes library. Went to bed, Next morning all my data had been copied to the NASLite and backed up to mirror drives. The shares were still patiently waiting on my desktop, ready to go.
The server has been rock solid for days. I pointed iTunes at the Media folder and it picked up all my files.
I don’t care that NASLite is updated very rarely ( years between releases ). Its feature set is fine for my home office needs.
I am still intrigued by unRAID's virtualization and docker support. I may build a machine that can take advantage of that one day and try it again. But in the meantime, I have work to do and unRAID has been a time sink for me.
BTW Automounter seems to have trouble with NASLite share. I will be glad to help you trouble shoot that if you want unless you have already solved that. I am just putting the disk shares into my account Login items and that seems to work perfectly.
Thanks for your help.
Spence
