* bcachefs: ob_dev()Kent Overstreet2024-05-081-0/+7
| | | | | | | Wrapper around bch2_dev_have_ref() for open_buckets; we do guarantee that the device an open_bucket points to exists. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: bch2_dev_iterate()Kent Overstreet2024-05-081-0/+8
| | | | | | New helper for getting refs to devices as we iterate. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: bch2_check_alloc_key() -> bch2_dev_tryget_noerror()Kent Overstreet2024-05-081-0/+25
| | | | | | More elimination of bch2_dev_bkey_exists() usage. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: bch2_dev_tryget()Kent Overstreet2024-05-081-0/+20
| | | | | | | | | | | Most uses of bch2_dev_bkey_exists() are going away, where we assume that because a key references a device the device most exist - instead, we'll be explicitly checking if the device exists and getting a reference to it. This adds the new helpers. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

| | | | | | | This will be used in the next patch for adding some new debug mode asserts. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

* bcachefs: Fix lifetime issue in device iterator helpersKent Overstreet2024-05-061-2/+2
| | | | | | | | | bch2_get_next_dev() and bch2_get_next_online_dev() iterate over devices, dropping and taking refs as they go; we can't access the previous device (for ca->dev_idx) after we've dropped our ref to it, unless we take rcu_read_lock() first.

* bcachefs: bch_member.btree_allocated_bitmapKent Overstreet2024-04-141-0/+21
| | | | | | | | | | | | | | | | | | | | | | | This adds a small (64 bit) per-device bitmap that tracks ranges that have btree nodes, for accelerating btree node scan if it is ever needed. - New helpers, bch2_dev_btree_bitmap_marked() and bch2_dev_bitmap_mark(), for checking and updating the bitmap - Interior btree update path updates the bitmaps when required - The check_allocations pass has a new fsck_err check, btree_bitmap_not_marked - New on disk format version, mi_btree_mitmap, which indicates the new bitmap is present - Upgrade table lists the required recovery pass and expected fsck error - Btree node scan uses the bitmap to skip ranges if we're on the new version Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

* bcachefs: bch_sb_field_errorsKent Overstreet2023-11-011-1/+1
| | | | | | | | | | | | Add a new superblock section to keep counts of errors seen since filesystem creation: we'll be addingcounters for every distinct fsck error. The new superblock section has entries of the for [ id, count, time_of_last_error ]; this is intended to let us see what errors are occuring - and getting fixed - via show-super output.

* bcachefs: Add IO error counts to bch_memberKent Overstreet2023-11-011-1/+41
| | | | | | | | | We now track IO errors per device since filesystem creation. IO error counts can be viewed in sysfs, or with the 'bcachefs show-super' command. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

* bcachefs: New superblock section members_v2Hunter Shaffer2023-10-221-0/+5
| | | | | | | | | | | members_v2 has dynamically resizable entries so that we can extend bch_member. The members can no longer be accessed with simple array indexing Instead members_v2_get is used to find a member's exact location within the array and returns a copy of that member. Alternatively member_v2_get_mut retrieves a mutable point to a member. Signed-off-by: Hunter Shaffer <huntershaffer182456@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

* bcachefs: sb-members.cKent Overstreet2023-10-221-0/+176
Split out a new file for bch_sb_field_members - we'll likely want to move more code here in the future. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
