Stuck at "verifying bzroot checksum ..." but no errors on console

Recommended Posts

I shutdown my unRAID machine to remove two unneeded disks and reroute cables. That went smoothly and the SAS controllers showed the right drives on the right interface.


While booting it spit out the following:


Checking /dev/sda1

fsck.fat 4.2 (2021-01-31)

There are differences between boot sector and its backup

This is mostly harmless. Differences: (offset:original/backup)


Not automatically fixing this

Dirty bit is set. Fs was not properly unmounted and some data may be lost

Automatically removing dirty bit.

/dev/sda1: 616 files, 92166/1874991 clusters

mount: /dev/sda1 mounted on /boot.

Verifying bzimage checksum ...

Verifying bzroot checksum ...


And there it sits. Pushing 30 minutes now.


Any ideas what may be going on? Do I interrupt it or let it run.


I am using unRAID v6.11.5.

I'll give it a shot. I thought the license was tied to some unique id on the USB stick though,


So I downloaded the USB creator, created a new flash drive with the correct version (6.11.5) and copied the old /config folder onto the USB /config.


Unfortunately it seems to have gotten worse. There are now dozens of listings after this text:

instead of just the one prior. And there it sits.


It's wondering what is going on that annoys me. Sigh

Just to make sure:

- Copy the /config directory off the flash drive

- Use the unRAID USB creator to rewrite the 6.11.5 version back on the stick

- Copy the /config directory back


Sorry for being dense but before I do destructive operations I want to make sure I understand the process. :)

Finally got time and puled the LSI SAS controller with no change. I them pulled the SAS Expander card (HP 468405-002) and disconnected it from the MB. Now I get a new error:



LZMA data is corrupt

-- System halted


That's after I redid the original USB with the latest unRAID writer (See above).


Gotta admit....This is a new error for me.
