March 13, 201610 yr I'm very new to playing with servers, command line, unRAID, etc but am having a awesome time learning and I must say I've spent many hours is these helpful, interesting pages. I've got my system setup and running and have been playing with dockers. Unfortunately I've stumbled through a few setups and ran into some problems. I wanted to start fresh so I deleted the docker image (using the webGUI) and started again. However having done this it left a whole bunch of legacy files/folders/settings. I moved on and setup a new docker image and installed my first package again. After it completed the docker page just displays an "orphan" docker which I can't delete. I tried a restart but the system hung on shutting down and I had to do a hard shutdown using a long press on the power button. I restarted, a parity check started and at this point I called it a night. (the parity check completed by the morning with 0 errors). I tried deleting the docker container again but no luck - wont let me - says something about a read only system file (I'm writing this from memory as I'm at work now). So I, probably stupidly , tried to delete the file using a telnet session. I also deleted the appdata folder I had created to store the config of my dockers. What I wan't to do is start again with a fresh install on my usb drive. Is this possible? Will I lose the data I have already put on my array? I assume the key licence will just work as the usb drive is the same GUID. The reason is that even if I find some way to make it all work happily again I worry that my poking around will come back to bite me later on with some obscure problem and always in the back of my mind I'll be thinking "you idiot, I bet this is because you played around with it back in the beginning". I guess you have to learn somehow but it'd be nice if there was a way out without losing my data.
March 13, 201610 yr If you start with a fresh install, then when you assign drives unRAID will recognise any that have been previously used by unRAID and will leave the data on them intact.
March 13, 201610 yr Author Awesome.... I'll try this out when I get home. If I understand correctly, even if I manage to get it wrong somehow the data on the data disk will remain intact all the same. I could still access it using something like the unassigned devices plugin or a system than can read xfs right?
March 13, 201610 yr You have to make sure that the parity drive is the same. If you put one of your data disk in parity slot, then you data on that disk will be gone.
