Right. The file system is 48T, with 17T available, so we're not quite
pushing it yet.
So far so good on the space_cache=v2 mount. I'm surprised this isn't on
the gotcha page in the wiki; it may end up making a world of difference
to the users here
Thanks again,
Matt

Thanks, I'll give space_cache=v2 a shot.
Yes, very much recommended.
My mount options are: rw,relatime,space_cache,autodefrag,subvolid=5,subvol=/
Turn autodefrag off and use noatime instead of relatime.
Your filesystem also seems very full,
We don't know. btrfs fi df only displays allocated space. And that being
full is good, it means not too much free space fragments everywhere.
that's bad with every filesystem but
*especially* with btrfs because the allocator has to work really hard to find
free space for COWing. Really consider deleting stuff or adding more space.
