* bcachefs: bch_member.btree_allocated_bitmapKent Overstreet2024-04-141-0/+53
| | | | | | | | | | | | | | | | | | | | | | | 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: helpers for printing data typesKent Overstreet2024-01-211-2/+2
| | | | | | We need bounds checking since new versions may introduce new data types. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Fix printing of device durabilityKent Overstreet2024-01-051-1/+1
| | | | | | | BCH_MEMBER_DURABILITY() was not present initially; a value of 0 means use the default, nonzero means use v - 1. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: bch_member->seqKent Overstreet2024-01-051-0/+5
| | | | | | | | | | | | | Add new fields for split brain detection: - bch_member->seq, which tracks the sequence number of the last superblock write that happened to each member device - bch_sb->write_time, which tracks the time of the last superblock write, to allow detection of when two members have diverged but had the same number of superblock writes.

| | | | | | Improved, better named version of pr_time(). Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Skip deleted members in member_to_text()Kent Overstreet2023-11-011-8/+7
| | | | | | | This fixes show-super output - we shouldn't be printing members that have been deleted. 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 Overstreet2023-11-011-17/+104
| | | | | | | | | 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: Fix kasan splat in members_v1_get()Kent Overstreet2023-11-011-3/+3
| | | | | | | This fixes an incorrect memcpy() in the recent members_v2 code - a members_v1 member is BCH_MEMBER_V1_BYTES, not sizeof(struct bch_member). Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: bch2_sb_field_get() refactoringKent Overstreet2023-10-221-12/+12
| | | | | | | Instead of using token pasting to generate methods for each superblock section, just make the type a parameter to bch2_sb_field_get(). Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

* bcachefs: New superblock section members_v2Hunter Shaffer2023-10-221-131/+272
| | | | | | | | | | | 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: Add new helper to retrieve bch_member from sbHunter Shaffer2023-10-221-0/+17
| | | | | | | | Prep work for introducing bch_sb_field_members_v2 - introduce new helpers that will check for members_v2 if it exists, otherwise using v1 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/+173
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>
