glennbrown Posted November 11, 2021 Share Posted November 11, 2021 So a little backstory I was running the trial of Unraid, decided to go back to Ubuntu + Snapraid/MergerFS setup since I wasn't sure I wanted to pay for Unraid. I think I have finally hit the point where dealing with the annoying little idiosyncrasies of the Ubuntu setup I want to just pay and move on with my life. So my question is when I converted the system back I just left the data disks as XFS with way Unraid had laid them out. I did delete/recreate the two cache pools. My question is if I take the USB stick that is still formatted will I be able to just pick up where I left off on the array side and re-create the cache pools. (I know I lost the docker.img and libvirt.img files). Below is the tree layout: ➜ tmp tree -L 1 /mnt/disk{1,2,3} /mnt/disk1 ├── downloads ├── isos ├── Movies ├── Music ├── Photos ├── Software └── TV Shows /mnt/disk2 ├── Movies ├── Photos ├── TV Shows └── Videos /mnt/disk3 ├── downloads ├── isos ├── Movies ├── Time Capsule ├── TV Shows └── Videos Quote Link to comment
trurl Posted November 11, 2021 Share Posted November 11, 2021 Should work. You don't mention parity but you will have to rebuild parity if any of the disks were ever mounted outside Unraid. Quote Link to comment
glennbrown Posted November 11, 2021 Author Share Posted November 11, 2021 I re-formated the parity drive for use in Snapraid anyway so was accounting for that. Should I re-create empty shares on the Array drives for appdata, domains, system before I boot from the USB drive? Quote Link to comment

I was going to put them on a cache pool but just wasn't sure if I should create empty folders on the array as well. Tomorrow going to boot backup into Unraid and will see how it goes.

If you setup those shares to use a pool, and you specify those shares in Settings - Docker and Settings - VM Manager, then folders for those shares will be created automatically on the specified pool. And in general, it isn't necessary to create any folders yourself for any user share. If you create a user share, Unraid will automatically create top level folders on pool or array as needed according to the settings for the share. Quote Link to comment
glennbrown Posted November 13, 2021 Author Share Posted November 13, 2021 Just wanted to report back, system is back up and everything is happy. Parity is rebuilding. Was nice and painless. Only real issue is completely not related to Unraid, the Plex DB's corrupted on me yet again. I am not sure why but they seem temperamental to being rsync'd this happened when I converted back to my Ubuntu setup too, Thank god for backups. 1 Quote Link to comment
