Unraid newbie: issues with my USB drive

[Timski]

Hi all .. first post, day 3 into my first Unraid server (Version: 6.12.3) so please go easy on me

 

I'm having a small (but atm catastrophic) hiccup with my USB drive. Having run on Trial license for 3 days (on an 8TB flash drive), I've upgraded my license to Pro and moved the license to a 32GB flash. All was fine until this morning when my USB reports as being (a) read-only and (b) only 8GB in size. Everything else is running perfectly (dockers seem fine, array seems fine, etc).

 

Following instructions at https://forums.unraid.net/topic/3118-how-to-fsck-my-usb-flash-drive/ but getting stuck with the USB still reporting the drive as busy, as follows:

Clearly I need to umount something else first, just no idea what. Any thoughts would be gratefully received 🙏

Just to confirm .. 32GB USB showing as 8GB

That looks like a flash drive, may be best to just replace it.

Brand new, bought yesterday  .. and the 3 others I bought yesterday all report as incompatible by the Unraid USB Flash Creator 😢

Still needs to be replaced, avoid generic flash drives, at least that one looks generic based on the device name.

Ordered some new USB drives.

 

While waiting, I did the following:

1. Backed up the USB drive

2. Removed USB from server, re-formatted it on Windoze 10

3. Manually copied backup zip contents to USB

4. Ran makeboot.bat as administrator

5. Returned USB to server, restarted --> ran into an exceptionally long mcelog daemon operation (probably was still running but I rebooted after about 20mins in frustration)

6. Unraid booted perfectly, USB disk showing up as 32GB

 

 

Not sure if the USB drive is suspect .. I may just swap it out when my new ones arrive (assuming Unraid USB Flash Creator will actually see any of the new USB's) but for now, Unraid is up and I can get busy migrating my 47TB Xigmanas server over to Unraid 😅

 

Thanks @JorgeB for your advice .. I will still be following your advice just to be safe 🙏

This tool seems to not work very well on some systems where the manual method works fine.
