System Details HPxz8600 (2) xeon 4350 processors, MB 24G ram, OS drive 128G SSD, 3 Seagate 4T enterprise drives PCIe HDA controller to enable JBOD for HDs Using flashmemory to improve performance and SSD life. Attempting to implement Mergerfs and Snapraid to set up a NAS with drive redundancy. I originally successfully set this system up and got plex running in a docker container, I wanted to add Photoprism but the plugin did not work correctly and also caused some other problems. One of the moderators suggested that since I was able to navigate installing Plex using Compose and Docker that I should do the same for Photoprism. Since the first pass was mostly painless I decided to do a fresh install and start from scratch. However each time I've tried I end up with a error message when I try to create a shared folder on the Mergerfs pool that says "directory /srv/mergerfs/POOL01/NASshare not created - unknown error" I've talked to my friend Google and my Uncle Bob as well as a couple LLMs and tried a variety of cli fixes for Mergerfs having permissions issues with newer versions of OMV, manually creating the directory and fixing the permissions, checking the disk space (99% free) and inode availability (more than 50,000 left), Manually un-mounting and remounting the Mergerfs pool. Freely admitting that my Linux skills are pretty rusty I'm at the end of my rope. Are their documented workarounds for this problem? I even created a new boot drive from the latest ISO to and that had the same issue

thanks Not being sure that I have all the folders your looking for here is a copy of the commands I used to try and clarify your question

I assume that you want these as well

thanks

I'm happy to do a fresh install and post the results now that I understand what I'm looking for, I've done it so many times it's second nature. like be less work for anyone trying to help

Still getting the same error

OMV thinks its there but CLI says not

Thanks for the tip, I see it in the GUI under Storage->Shared Folders. I'm 99% sure that I deleted everything through the GUI and confirmed that it was gone in the CLI and then started over Rather than playing blindman's bluff I can rebuild the OMV instance from scratch and detail what i do as I go to be sure that this is not a sophomoric mistake before I burn a bunch of your time?

Well, sophomoric mistake or not following good advice notwithstanding, I tried one more time to follow the excellently produced and well explained You Tube video that I had successfully used to build a NAS using OMV, Flashmemory, Mergerfs, and Snapraid. Still worth a view; overall explanation of what you're doing and why as well as lots of small details that other videos I watched missed as I tried to decide between prox mox , Truenas, unraid and OMV see it here

. I got the same results I've been getting, So I made a new USB bootable drive and went through the installation step by step as outlined in the documentation on the OMV website. Guess what? it worked! I guess the comments from forum members on do the work, skip You Tube is good advice. Since the Photoprism pugin doesn't seem to work on my hardware and One of you said I should just user docker anyway, I have started reading up on Docker on the OMV-extras website. They recommend installing the OS and Docker on different drives. The USB that my MB uses is pretty slow, so I opted not to use a pen drive for the OS. It's on 128G SSD drive connected to a SATA port on the MB. After reading the beginner notes on containers it makes total sense to have containerized apps running on their own resources I'm running

Does it make sense to invest in another 128G SSD to run the Docker apps on?

Thanks for your patience

can I move the OS to a pendrive or do I have to start Fresh
