Hi,

I'm not sure if they matter, but I got these warnings on
one of the machines I'm using as a Ceph OSD server:

[ 1806.549469] ------------[ cut here ]------------
[ 1806.554593] WARNING: at fs/btrfs/extent-tree.c:5790
use_block_rsv+0xa7/0x101 [btrfs]()

Please let me know if I can do anything to help sort these out.


I just posted a patch for this problem, it's titled

Btrfs: fix how we do space reservation for truncate

Please apply it and test it and see if it makes this problem go away.

This patch has been working very well for me, thanks.
I've had no sign of truncate trouble since I started using it.

Fantastic, thank you for testing.
