January 22, 20233 yr Hey all, So my server gave up the ghost and will no longer boot. Will need to do some testing at a later stage, but for now I'm building up a new server. I have taken my usb key (although I have a new one that I want to use and do a clean unRAID install) So the only real thing I need is my drive layout, especially which drives were my parity. Is this info somewhere on the USB key that I can get all the drives as I'll be keeping the data drives intact in a new server. Also... my drives are encrypted, so if I set the same encryption key will this negate this issue on the new server?

The OS is unpacked fresh from archives on flash, into RAM, at each boot, and the OS runs completely in RAM. Think of it as firmware. So, every boot is a "clean install", except: The flash drive also stores configuration information (all settings from your webUI), in the config folder on flash so they can be reapplied at boot. Your drive assignments are in config/super.dat and config/pools. You can keep as much of your configuration as you want with your new server. As long as no RAID controllers are involved, either on the old or new server. Otherwise there may be some issues to work through. And, of course, if you have any hardware passthru to VMs that will have to be worked out on the new system.

I will have new SAS controller as I'm going from backplane to just straight up SAS to SATA Was also thinking it would be nice to start fresh... So just gotta go through it. But on the new server I just wanted to add which drives were Data and which were Parity from old Server...

Not too hard to see which webUI settings correspond to which entries in which files there. Took a look at config/super.dat as you suggested. Issue is it seems to just be a list of all the drives with a bunch if ? and other almost corrupt looking characters around But it doesnt show me which drive was parity and which were like data 1 through 16 Is there a way to find that? Or a way to open that .dat on Mac?
January 23, 20233 yr Community Expert IF you have Notifications setup, look at the e-mails from that by that process. Some of them do contain the drive assignments. (Remember, you probably have two copies of each message--- one in the outgoing mail and one in the inbox.)
January 23, 20233 yr Why not just boot with the USB? The drives will be shown in unraid UI - either as existing or missing.

But that is the file Unraid will read to get your disk assignments. Edit config/disk.cfg to disable autostart, then 1 hour ago, apandey said: Why not just boot with the USB?

Also, this post from a few months ago has your diagnostics, and plenty of ways to see disk assignments in those. Of course you may have changed them since then.
