October 14, 20241 yr Hello Everyone, I have my Unraid server from 6years or so, and I would like to do a fresh install. Since I've around 40Tb data, I would like to know if it's possible (and how) to do a fresh install without loosing all my data. My array is an encrypted XFS. Thank you in advance for any hints and/or procedure.
October 14, 20241 yr das würde mich auch interessieren stehe vor dem selben Problem das mein Unraid 3 Lietzens Schlüssel am stick hat und viele Fehler ausgibt etc. Möchte auch von vorne beginnen ohne alle daten zu verlieren und ich hab auch einiges am server liegen skynet1-syslog-20241014-0330.zip

Hello Frank, Because over the years, I've "played" with a lot of things (ssh over certs, customizations, and so on... ) , and I would like to rebuilt it from scratch. For this reason, I would like to know if it's possible to "not" loose my array.
October 14, 20241 yr Community Expert The encryption may be a problem. Otherwise, you need to know what drives are assigned to what disk slots. (A screenshot/printout of the MAIN tab will contain all of this information.) If you want to preserve other settings--- like server name, you would need to make notes or more screenshots of those settings. Normally, you would just assign all the hard disks to the same Disk slot numbers using the HD's serial number. After starting the array, all of your data would be there. Of course, you will lose all plugins, Dockers and VM's. But presumably this is why you want to a 'fresh' install...

So - of course Dockers&co should be done by scratch (I'm backupping them since day one, so I could restore them without a problem theoretically). But then, only the "order" of the HDD shoudl matter? What problem could I encounter with the encryption? Of course, as a test, I could simply use another USB drive with unraid to test the "new" setup. But I'm really intrested in the "possible problems" with encrypted drives. Edited October 14, 20241 yr by TDA

I said: 1 hour ago, Frank1940 said: The encryption may be a problem. I have never used Hard Drive encryption before so I have no knowledge about any precautions that should be taken. I assume that recovering data from any encryption scheme is very, very difficult (if not impossible) if the things are not handled properly. I wanted you to realize this before you started and to investigate this potential problem. (It may well be that all you need is the 'key' and you can unlocked the data in your new array setup. But I am not sure if this is true...)

I wait for some other comments, but in any case, I think I could (if it's safe) to build another usb-key, and try to run the whole system to see if it boots with the data.

Thank you in advance for any hints and/or procedure. I would always take a backup before starting, and make sure your encryption keys are safe also... but there is a plugin to do just this.

Hello, I'll try it next month when I have finally vacation and have time. I want a fresh install because I played to much over the years and I want a hardened installation from scratch without loosing the 40/50Tb of data 🙂
