Error initializing module 'btrfs'

Dear all,
I use Alma 9.5 and for a while I get an error log in Cockpit under Storage log:

Error initializing module 'btrfs': /usr/lib64/udisks2/modules/libudisks2_btrfs.so: cannot open shared object file: No such file or directory

This message appears once a day at random time. I do not use any partition with Btrfs filesystem.
I would like to know if I’m alone to get this message and if anybody can help me to solve this annoying error log message?

Best regards,

Hi,
I figured out that this error happens when I log in into the cockpit.
So it seems that cockpit needs this module to be present and it throws out this error in the logs when I log in.
Strange?!

Best regards,

This happens because Cokpit asks UDisks to enable btrfs unconditionally. You don’t really need to worry about this error.

Dear pastalian,
thank you for the explanation. :+1:
I agree with you, but it is such a disturbing message, that I really do not like it. Hopefully somebody will fix this.
