2023-10-23bcachefs: Only allocate buckets_nouse when requestedKent Overstreet1-0/+5
It's only needed by the migrate tool - this patch adds an option to enable allocating it. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: bch2_journal_entry_to_text()Kent Overstreet1-0/+2
This adds a _to_text() pretty printer for journal entries - including every subtype - which will shortly be used by the 'bcachefs list_journal' subcommand. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: BCH_JSET_ENTRY_logKent Overstreet1-0/+5
Add a journal entry type for logging messages, and add an option to use it to log the transaction name - this makes for a very handy debugging tool, as with it we can use the 'bcachefs list_journal' command to see not only what updates were done, but what was doing them. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Kill non-lru cache replacement policiesKent Overstreet1-1/+0
Prep work for persistent LRUs and getting rid of the in memory bucket array. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Turn encoded_extent_max into a regular optionKent Overstreet1-0/+6
It'll now be handled at format time and in sysfs like other options - it still can only be set at format time, though. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Option improvementsKent Overstreet1-15/+25
This adds flags for options that must be a power of two (block size and btree node size), and options that are stored in the superblock as a power of two (encoded extent max). Also: options are now stored in memory in the same units they're displayed in (bytes): we now convert when getting and setting from the superblock. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Add more time_statsKent Overstreet1-3/+3
This adds more latency/event measurements and breaks some apart into more events. Journal writes are broken apart into flush writes and noflush writes, btree compactions are broken out from btree splits, btree mergers are added, as well as btree_interior_updates - foreground and total. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Specify filesystem optionsKent Overstreet1-53/+54
We've got three types of options now - filesystem, device and inode, and a given option may belong to more than one of those types. This patch changes the options to specify explicitly when they're a filesystem option - in the future we'll probably be adding more device options. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Convert journal sysfs params to regular optionsKent Overstreet1-1/+11
This converts journal_write_delay, journal_flush_disabled, and journal_reclaim_delay to normal filesystems options, and also adds them to the superblock. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Fix quota support for snapshotsKent Overstreet1-6/+6
Quota support was disabled when snapshots were released, because of some tricky interactions with snpashots. We're sidestepping that for now - we're simply disabling quota accounting on snapshot subvolumes. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: More enum stringsKent Overstreet1-1/+4
This patch converts more enums in the on disk format to our standard x-macro-with-strings deal - to enable better pretty-printing. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Improve transaction restart handling in fsck codeKent Overstreet1-0/+5
The fsck code has been handling transaction restarts locally, to avoid calling fsck_err() multiple times (and asking the user/logging the error multiple times) on transaction restart. However, with our improving assertions about iterator validity, this isn't working anymore - the code wasn't entirely correct, in ways that are fine for now but are going to matter once we start wanting online fsck. This code converts much of the fsck code to handle transaction restarts in a more rigorously correct way - moving restart handling up to the top level of check_dirent, check_xattr and others - at the cost of logging errors multiple times on transaction restart. Fixing the issues with logging errors multiple times is probably going to require memoizing calls to fsck_err() - we'll leave that for future improvements. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Disable quota supportKent Overstreet1-6/+6
Existing quota support breaks badly with snapshots. We're not deleting the code because some of it will be needed when we reimplement quotas along the lines of btrfs subvolume quotas. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Enabled shard_inode_numbers by defaultKent Overstreet1-1/+1
We'd like performance increasing options to be on by default. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Add an option for btree node mem ptr optimizationKent Overstreet1-0/+5
bch2_btree_node_ptr_v2 has a field for stashing a pointer to the in memory btree node; this is safe because we clear this field when reading in nodes from disk and we never free in memory btree nodes - but, we have bug reports that indicate something might be faulty with this optimization, so let's add an option for it. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Add an option for whether inodes use the key cacheKent Overstreet1-0/+5
We probably don't ever want to flip this off in production, but it may be useful for certain kinds of testing. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: bch2_d_types[]Kent Overstreet1-0/+1
Add readable names for d_type, and use it in dirent_to_text(). Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Add an option to control sharding new inode numbersKent Overstreet1-1/+6
We're seeing a bug where inode creates end up spinning in bch2_inode_create - disabling sharding will simplify what we're testing. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23bcachefs: Kill reflink optionKent Overstreet1-5/+0
An option was added to control whether reflink support was on or off because for a long time, reflink + inline data extent support was missing - but that's since been fixed, so we can drop the option now. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Use x-macros for more enumsKent Overstreet1-6/+5
This patch standardizes all the enums that have associated string tables (probably more enums should have string tables). Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Rename BTREE_ID enums for consistency with other enumsKent Overstreet1-0/+1
Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Use x-macros for compat feature bitsKent Overstreet1-0/+1
This is to generate strings for them, so that we can print them out. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Redo checks for sufficient devicesKent Overstreet1-0/+5
When the replicas mechanism was added, for tracking data by which drives it's replicated on, the check for whether we have sufficient devices was never updated to make use of it. This patch finally does that. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Add an option for metadata_targetKent Overstreet1-0/+5
Also, make journal writes obey foreground_target and metadata_target. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Indirect inline data extentsKent Overstreet1-1/+1
When inline data extents were added, reflink was forgotten about - we need indirect inline data extents for reflink + inline data to work correctly. This patch adds them, and a new feature bit that's flipped when they're used. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Fix for passing target= opts as mount optsKent Overstreet1-1/+1
Some options can't be parsed until the filesystem initialized; previously, passing these options to mount or remount would cause mount to fail. This changes the mount path so that we parse the options passed in twice, and just ignore any options that can't be parsed the first time. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Fix maximum btree node sizeKent Overstreet1-1/+1
Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Add an option for rebuilding the replicas sectionKent Overstreet1-0/+5
There is a bug where we cnan end up clearing the data_has field in the superblock members section, which causes us to skip reading the journal and thus journal replay fails. This option tells the recovery path to not trust those fields. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Add an internal option for reading entire journalKent Overstreet1-0/+5
To be used the debug tool that dumps the contents of the journal. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Add an option to disable reflink supportKent Overstreet1-0/+5
Reflink might be buggy, so we're adding an option so users can help bisect what's going on. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Add an option for keeping journal entries after startupKent Overstreet1-0/+5
This will be used by the userspace debug tools. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Convert some enums to x-macrosKent Overstreet1-8/+9
Helps for preventing things from getting out of sync. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Put inline data behind a mount option for nowKent Overstreet1-0/+5
Inline data extents + reflink is still broken Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-23bcachefs: Don't use sha256 for siphash str hash keyKent Overstreet1-1/+1
With the refactoring that's coming to add fuse support, we want bch2_hash_info_init() to be cheaper so we don't have to rely on anything cached besides the inode in the btree. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Kill deferred btree updatesKent Overstreet1-7/+1
Will be replaced by cached btree iterators Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Switch reconstruct_alloc to a mount optionKent Overstreet1-0/+5
Right now this is the only way of repairing bucket gens in the future Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-23bcachefs: Lots of option handling improvementsKent Overstreet1-139/+247
Add helptext to option definitions - so we can unify the option handling with the format command Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-23bcachefs: Make bkey types globally uniqueKent Overstreet1-0/+3
this lets us get rid of a lot of extra switch statements - in a lot of places we dispatch on the btree node type, and then the key type, so this is a nice cleanup across a lot of code. Also improve the on disk format versioning stuff. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
