bcachefs: Fix failure to return error in data_update_index_update()

2024-08-27T00:33:12Z

This fixes an assertion pop in io_write.c - if we don't return an error we're supposed to have completed all the btree updates. Signed-off-by: Kent Overstreet

bcachefs: Fix "trying to move an extent, but nr_replicas=0"

2024-08-22T06:07:22Z

data_update_init() does a bunch of complicated stuff to decide how many replicas to add, since we only want to increase an extent's durability on an explicit rereplicate, but extent pointers may be on devices with different durability settings. There was a corner case when evacuating a device that had been set to durability=0 after data had been written to it, and extents on that device had already been rereplicated - then evacuate only needs to drop pointers on that device, not move them. So the assert for !m->op.nr_replicas was spurious; this was a perfectly legitimate case that needed to be handled. Signed-off-by: Kent Overstreet

bcachefs: bch2_data_update_init() cleanup

2024-08-22T06:07:22Z

Factor out some helpers - this function has gotten much too big. Signed-off-by: Kent Overstreet

bcachefs: Extra debug for data move path

2024-08-20T01:42:08Z

We don't have sufficient information to debug: https://github.com/koverstreet/bcachefs/issues/726 - print out durability of extent ptrs, when non default - print the number of replicas we need in data_update_to_text() Signed-off-by: Kent Overstreet

bcachefs: Make bkey_fsck_err() a wrapper around fsck_err()

2024-08-14T03:00:50Z

bkey_fsck_err() was added as an interface that looks like fsck_err(), but previously all it did was ensure that the appropriate error counter was incremented in the superblock. This is a cleanup and bugfix patch that converts it to a wrapper around fsck_err(). This is needed to fix an issue with the upgrade path to disk_accounting_v3, where the "silent fix" error list now includes bkey_fsck errors; fsck_err() handles this in a unified way, and since we need to change printing of bkey fsck errors from the caller to the inner bkey_fsck_err() calls, this ends up being a pretty big change. Als,, rename .invalid() methods to .validate(), for clarity, while we're changing the function signature anyways (to drop the printbuf argument). Signed-off-by: Kent Overstreet

bcachefs: Warn on attempting a move with no replicas

2024-07-10T13:53:39Z

Instead of popping an assert in bch2_write(), WARN and print out some debugging info. Signed-off-by: Kent Overstreet

bcachefs: bch2_dev_have_ref()

2024-05-08T21:29:24Z

bch2_dev_bkey_exists() is going away; bch2_dev_have_ref() documents that we're looking up a device without checking if it's present because we have a reference to it already. Signed-off-by: Kent Overstreet

bcachefs: kill bch2_dev_bkey_exists() in data_update_init()
