I wondering a TW update will do the root fs conversion at some point or if there is a reason they are holding back?
The only way to convert the FS is to do it offline, and there wouldn't be any plans to "upgrade" existing installs. I don't know any other distro that would do this either except for extreme circumstances. Messing with the filesystem metadata of live systems is just asking for trouble.
Starting with bftrfs-progs 5.15 space_cache=v2 is the default, so even if it's not been set explicitly, new installs should be using it as far as I'm aware.
What are you using to backup your rootfs and all the subvolumes that the installation creates and then putting it all back?
Nothing special, just tar.
I get that new installs would use space_cache=v2, but there are lots of existing installations so I was wondering if TW would auto migrate existing installations OR if there is a reason that they have purposely not migrated existing installations. In case anyone else is interested, I just tested out in a vm and was able to easily switch between v1 and v2 of space_cache ( and back ) Just add ',clear_cache,space_cache=v2' to the options for the '/' mount in /etc/fstab and reboot. To switch back just change it to v1 and reboot again. Once you have rebooted and have it set to your desired space_cache version, you can remove from /etc/fstab and future reboots will use the last value. -- Regards, Joe
