December 24, 20241 yr Hi, I recently acquired an icy box usb jbod. I have a microserver and while i'm aware rebuilding it in a new case with sata card and such would be a better option, at the moment i cannot justify the price. It would mean a brand new server for me. So i'm using it for now and honestly i dont have much complaint with it. Speed is fine for media and downloads. It holds no irreplaceable data. The issue is i didnt know unraid handles is weirdly when i set it up. So right now it has a single drive. My server was running, i have stopped the array, plugged in the usb, added the new disk to the array and was happy. Until i had to restart the server and I noticed that the drive is not mounted, it said missing. Unplug, replug usb and I was able to select the drive and start the array. But the issue is my server is now unable to start automatically I have to babysit it. What I noticed is when I start unraid os with the usb jbod plugged in it gets a very normal looking HDD serial number, however when you hot plug it in while the os is running it gets a very generic 00000003 serial. Obviously i should have done the first option then i would have no trouble but here I am. So..: Now I need to know how I can replace a disk while content is 100% the same but different serial. I know it might be a weird edge case but it happens as you see. I dont have parity drive, its a media server.
December 24, 20241 yr Community Expert USB can have issues with IDs, but only after hot plug is strange, grab diags after a fresh boot and after a hot plug, and post both.
December 24, 20241 yr Author Here you go. The IDs are same as my first screenshot in the post, IDs are not changing. tevenas-diagnostics-hotplug.zip tevenas-diagnostics-normal-boot.zip
December 24, 20241 yr Community Expert 1 hour ago, daninet said: IDs are not changing. They are changing for disk3, I had understood that it got the correct ID after a normal boot, but it's the other way around, since there's no parity, you can do a new config after a normal boot, then just don't hot plug the device and it will be fine.
December 24, 20241 yr Author Circling back to my original question from the first post, can i somehow replace the IDs so i dont have to copy all my data somewhere to redo the array? I dont have that much free space. Edited December 24, 20241 yr by daninet
December 24, 20241 yr Community Expert You have no control over the disk identifiers. Just New Config as suggested, no need to copy any data anywhere. https://docs.unraid.net/unraid-os/manual/tools/#new-config
