Recently backing up Qubes has been failing with a message:
Whoops. A critical error has occurred. This is most likely a bug in Qubes Global Setting application. StoragePoolException: file pool cannot export dirty volumes at line 102 of file base.py
I am running Qubes 4.0, regularly updated. I haven’t been able to find anything that looks relevant in the logs. I can’t find anything that looks wrong in the global settings database, either from the CLI or GUI. I have tried rebooting numerous times, starting the backup immediately after a boot or just before shutdown. I saw a different “StoragePoolException” once, though I didn’t write it down and haven’t reproduced it yet.
Any suggestions on how to track this down and fix it?
