RootFS created when sda3 was 897.76GB and sdb3 311.82GB.
I have now freed other space on sdb. So I deleted sdb3 and recreated
it occupying all available space.

/dev/sdb3 is the same.

How can I resize /dev/sdb3?

=C2=A0 I think the syntax you need is btrfs fi resize max /mnt/RootFS=

:2

It's wrong :(

=2E/btrfs fi resize max /mnt/RootFS:2
ERROR: can't access to '/mnt/RootFS:2'

=C2=A0 But I could be wrong. If it works, can you add it to the UseCa=

ses

page on the wiki, please?

Sure.
