covertneko Posted April 22, 2020 Share Posted April 22, 2020 (edited) I just restarted my array and now all of my dockers are gone, as well as my appdata folders (well, most of them. Some were left behind in a broken state). I'm running Unraid 6.8.3 with the community applications plugin. I also installed the user scripts and unassigned devices plugins, but have not used them yet. I have a one parity drive, two data drives, and two cache drives. Leading up to this, my flash drive died on me after several months of unraid working flawlessly. Unfortunately I had no idea where I put my backup and have doubts that I even made one despite thinking so. No big deal, I took note of my array setup and installed unraid on a new drive, set everything up exactly as before (minus my second cache drive because no matter how many times I changed the array slot count or restarted unraid, I could never select more than 1 cache slot), ran a parity check overnight with 0 errors, and began reconfiguring my shares and plugins today. I was extremely happy to see that all of my dockers were intact and had even started automatically. I was able to log into my unifi controller and make some changes to my network that I had been unable to make while my server was dead. Then I noticed that I could finally select more than one cache drive in the Main tab, so I added my second unassigned cache drive and restarted my array. Then I noticed I could no longer access my unifi controller, and that my Docker tab was completely empty. I checked my appdata folders and at first glance they seemed fine, so I reinstalled the unifi controller and started it again. It didn't work and was unable to access its database. Same thing with nginx proxy manager. So now I'm panicking a bit. Reinstalling and running the dockers overwrote what little appdata still existed, and I have no idea why some half-broken appdata folders remained while others completely disappeared. At this point my array is stopped and I'm not starting it again until I know I'm not going to randomly lose even more important data than what was already lost. I feel like an idiot for not having more recent backups, and really hate the idea of losing my network configuration due to this. I share a network with some family members and have vlans set up which will be a nightmare to reconfigure, but not impossible. I was going to use this whole flash drive debacle as motivation to finally finish setting up proper scheduled backups so this really stings. Is there any remote possibility whatsoever that I can get my appdata folders back? Did adding the second cache drive do something weird? Why was everything working perfectly until I restarted my array? Any sort of insight would be hugely appreciated. Even if I can't get my data back I'd like to at least know if I can even trust this system at this point. I've attached a diagnostics zip from shortly after I stopped my array. I haven't rebooted since yesterday before the parity check. nas1.winkel.io-diagnostics-20200421-2114.zip Edited April 22, 2020 by covertneko add solved to title Quote Link to comment
JorgeB Posted April 22, 2020 Share Posted April 22, 2020 You formatted the cache pool, so any data there is gone, unless you have a backup. Quote Link to comment
covertneko Posted April 22, 2020 Author Share Posted April 22, 2020 Oh my god I'm an idiot. I completely forgot appdata was on the cache. Thank you. It's a relief to know I just screwed up something simple and didn't accidentally delete something irreplaceable. All the more reason to set up proper backups this time. Quote Link to comment
trurl Posted April 22, 2020 Share Posted April 22, 2020 Go to Apps and search for the CA Backup plugin Quote Link to comment
