Hello list,
just wanted to report that my ENOSPC errors are gone. Thanks to wang for
his great patches.
but the space_info corruption still occours.
On every umount i see:
[93022.166222] BTRFS: space_info 4 has 208952672256 free, is not full
[93022.166224] BTRFS: space_info total=363998478336, used=155045216256,
pinned=0, reserved=0, may_use=524288, readonly=65536
I see. Could you provide your mount options and kernel version(git
repertory), then
I can look into the codes :)
Regards,
Xiaoguang Wang
Greets,

I cannot confirm that as i do not have anough space to test this without
compression ;-( But yes i've compression enabled.
I might not get you, my poor english :)
You mean that you only get ENOSPC error when compression is enabled?
And when compression is not enabled, you do not get ENOSPC error?
I can't tell you. I cannot test with compression not enabled. I do not
have anough free space on this disk.
I'm trying to fix it.
That sounds good but do you also get the
BTRFS: space_info 4 has 18446742286429913088 free, is not full
kernel messages on umount? if not you might have found another problem.
Yes, I seem similar messages, you can paste you whole dmesg info here.
