Howto debug the boot sequence and udev because bcache is not working after a reboot in Debian 12



Hi,

I am trying to speed up a data device using bcache.  It worked in the
past with Debian 9.  I am now trying again with current Debian 12.

I created two bcache devices in the server but wrote data in only one.
When I reboot I am not getting back the two bcache devices, only the
pristine one.  I am trying to find the cause of the problem with
bcache, I see no explainable errors in dmesg ou "jounalctl -b" and
when I try to reattach the missing bcache I see no errors and works.
No data is lost.

I see too that the links /dev/bcache/by-uuid are missing, so some
problem is possible with udev or bcache rules for it.

How do I debug the boot sequence and the udev rules to understand what
is wrong with my bcache in Debian 12?


Kind regards
Jose M Calhariz
