btrfs check, persistent "reset isize for dir" messages

btrfs check, persistent "reset isize for dir" messages

[Chris Murphy]

btrfs-progs 5.11.1

User is reporting many "reset isize for dir" messages with btrfs
check, even following use of --repair. What does this message mean, is
the file system OK, why aren't they actually being reset? Would a
btrfs-image help?

I'll ask them to retest with btrfs-progs 5.12.1 and include lowmem
output as well as regular mode.

There are numerous other errors still with the file system, following
--repair, using btrfs-progs 5.12.1. But it looks like the "reset size
for dir" messages are gone.
