Is this with `v0.10` or `master`? See #296. Things have improved a lot recently, particularly for handling snapshots and reducing fragmentation.
It's the first line of output: ``` # bees bees version v0.10-33617-gab288ff84 ``` It also appears in `beesstats.txt`: ``` Now: 2024-12-11-02-29-22 Uptime: 93379 seconds Version: v0.10-33617-gab288ff84 ```
There is a utility in the [`python3-btrfs`](https://github.com/Knorrie/python-btrfs) package called `btrfs-balance-least-used` which will target the lowest-usage block groups first, until the limit specified by `-u` is reached: `btrfs-balance-least-used -u 80` You...
The loss of performance is concerning. Dedupe will leave behind a lot of small free space holes and btrfs isn't great at filling small free space holes. Balance won't fix...

btrfs send does not attempt to make reflinks to any extent with more than 64 references: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/fs/btrfs/send.c#n1553 ``` /* * Backreference walking (iterate_extent_inodes() below) is currently * too expensive when...
There are multiple agents here. The documentation could be clearer. The _scrub_ is read-only, i.e. errors found in blocks that are read and verified _by the scrub ioctl_ are not...
