Could a parameter be added to allow bcachefs to delay writes to background target until a certain % of foreground cache is filled? this is mainly for power-saving reasons: if...

A few days ago, I gave up on hardware raid (due to having MANY issues with different controllers) and am preparing to go for linux software raid instead. An idea...

I have a bcachefs device which was formatted with a 512 byte block size: ``` External UUID: 297427bf-7336-4e74-ab85-6bb076f446d0 Internal UUID: 47da8004-3826-413c-a6a2-173d533cfa94 Device index: 9 Label: securestorage Version: fragmentation_lru Oldest version...

The cause of it may very well be something else, but I have no clue, so maybe ... maybe someone has an idea what to verify. I have a backup...

(particularly important with cross-compiling & experimenting with build-test-kernel in ktests): when running "make clean", the rust binaries are not removed. As such, when cleaning because build-test-kernel is running on another...

I noticed the following 2 (very similar) lines: ``` bch2_bpos_to_text(&PBUF(buf3), b->data->min_key); bch2_bpos_to_text(&PBUF(buf3), b->data->max_key); ``` is it possible the latter one needs to point to buf4? this one was allocated, a...

bcachefs format --discard scope

The--discard parameter scope does not start at the begin of a new group: ``` linuxserver /home/janpieter # bcachefs format -g SSD --discard /dev/disk/by-partuuid/f8d16ed7-eddc-4ef1-84b7-bc3b74e8b3ca -g HDD /dev/sdd --foreground_target=SSD --promote_target=SSD --background_target=HDD External...

bcachefs fsck never completes, it hangs after `flushing journal and stopping allocators complete` I investigated it with gdb: ``` (gdb) info threads Id Target Id Frame * 1 Thread 0x7fb07c46db80...

I saw an issue when I performed a "show-super" on the HDD device (bcachefs show-super /dev/sdb1): `External UUID: 9cac6a05-1bd9-422a-9b93-2a2c53dc6e51 Internal UUID: 0781f15e-09b0-4ef2-967a-fb499dd0f9ac Label: Version: 11 Created: Wed May 20 08:01:51...
