Vitaliy Filippov	a061246997	Do not attempt to initialize QEMU driver via vitastor_c_create_qemu_uring() ... It doesn't add any compatibility because vitastor_c_uring_register_eventfd() is added in the same VITASTOR_C_API_VERSION 2.	2023-10-26 17:46:19 +03:00

Vitaliy Filippov	6acf562e01	Release 1.0.0 ... New features: - Data and metadata checksums! - Metadata checksums are always used with new disk format - Data checksums can be turned on with --data_csum_type crc32c for new OSDs - Checksum block size can be configured - inmemory_metadata now also affects keeping checksums in memory - Linux page cache I/O caching support which can be enabled separately for data, metadata (including checksums) and journal (O_SYNC instead of O_DIRECT) - Details [here](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/config/layout-osd.en.md#data_csum_type) - Backwards compatibility is preserved, you can use new OSDs with old disks Release also includes bug fixes from [0.9.6](https://git.yourcmc.ru/vitalif/vitastor/releases/tag/v0.9.6). 0.9.6 is moved to "-oldstable" repositories and will be available for some additional time.	2023-07-29 18:57:19 +03:00

Vitaliy Filippov	4181add1f4	Remove creepy "metadata copying" during overwrite ... Instead of it, just do not verify checksums of currently mutated objects. When clean data modification during flush runs in parallel to a read request, that request may read a mix of old and new data. It may even read a mix of multiple flushed versions if it lasts too long... And attempts to verify it using temporary copies of metadata make the algorithm too complex and creepy.	2023-07-29 12:17:18 +03:00
Vitaliy Filippov	a8464c19af	Support keeping checksums on disk (not in memory) ... Definitely beneficial for SSD+HDD setups	2023-07-29 12:17:18 +03:00

Vitaliy Filippov	e651c93a90	Release 0.9.6 ... - Fix vitastor-disk partition zeroing (sometimes it was writing garbage instead of zeroes) - Fix incorrect EC space statistics in `vitastor-cli status` - Several bug fixes for NFS: - Add . and .. in NFS directory listings - Return FILE_SYNC from NFS writes if immediate_commit is enabled - Return the same "verifier" in NFS COMMIT as in NFS WRITE - Make parallel NFS extending writes work correctly, without conflicts - Handle parallel NFS extending writes without imposing extra load on etcd - Support UTF-8 in vitastor-cli table output - Also allow "0" and "no" as false for inmemory_metadata and inmemory_journal - Use HDD defaults for HDD-only in automatic `vitastor-disk prepare` mode	2023-07-29 10:54:00 +03:00
Vitaliy Filippov	988e90be69	Fix vitastor-disk partition zeroing (it was writing random garbage instead of zeroes :D)	2023-07-28 12:29:07 +03:00
Vitaliy Filippov	700e0e9bff	Handle parallel NFS extending writes without imposing extra load on etcd	2023-07-27 02:26:17 +00:00
Vitaliy Filippov	ab0ca7c00f	Return FILE_SYNC from NFS writes if immediate_commit is enabled	2023-07-26 02:09:47 +03:00
Vitaliy Filippov	f153bc950b	Return the same "verifier" in NFS COMMIT as in NFS WRITE ... This fixes buffered (not O_DIRECT) NFS writes in Linux - previously they were hanging in an infinite loop because COMMIT didn't return the same verifier as previous WRITEs, and NFS kernel client was infinitely retrying the same writes. Also this probably allows for correct NFS failover, at least for the same buffered writes, because NFS clients repeat all write requests until a COMMIT confirms them.	2023-07-26 02:09:47 +03:00
Vitaliy Filippov	425ff8818d	Add . and .. in NFS directory listings ... MC, for example, hangs with infinite listing retries without them	2023-07-26 02:09:47 +03:00
Vitaliy Filippov	9e287a7778	Handle extending writes correctly in NFS proxy ... Previously, multiple parallel writes extending file size through NFS were racing with each other and triggering deletions of part of the written data I.e. if you mounted vitastor-nfs and just copied a file into it in MC then you could end up with only a part of the file actually written	2023-07-26 02:09:43 +03:00
Vitaliy Filippov	f52f58b9e9	Support UTF-8 in vitastor-cli table output	2023-07-25 01:48:57 +00:00

Vitaliy Filippov	10a5fd6abb	Release 0.9.5 ... A hotfix to 0.9.4 containing only one bugfix: 100% CPU usage in the new QEMU driver caused by the lack of eventfd reset on io_uring event handling :)	2023-07-21 00:04:41 +03:00

You are officially allowed to use HDD-only Vitastor with HGST/Toshiba/EXOS :)	2023-07-19 02:50:30 +03:00
Vitaliy Filippov	d0e257ee81	Fix non-existing pool handling in `vitastor-cli ls`	2023-07-18 23:52:02 +03:00
Vitaliy Filippov	9815d70ffc	It is impossible to use io_uring with older vitastor-client because it does not have vitastor_c_uring_has_work()	2023-07-18 23:37:53 +03:00
Vitaliy Filippov	4a4627dcab	Do not use bool in C library	2023-07-18 23:37:53 +03:00
Vitaliy Filippov	ba7427020e	Fix deadlocks possible in qemu-img after fixing iothread ... Deadlock was caused by switching QEMU coroutines directly inside vitastor_co_read_bitmap_cb() callback. The correct way is to schedule a BH /BH is a QEMU term for setImmediate() :)/, same as in read and write callbacks.	2023-07-18 23:32:16 +03:00
Vitaliy Filippov	ac7b834af3	Disable journal_no_same_sector_overwrites by default for HDD-only	2023-07-10 00:34:35 +03:00
Vitaliy Filippov	57ad4c3636	Add a note about HDD, enable throttling only for hybrid OSDs	2023-07-09 12:45:11 +03:00
Vitaliy Filippov	b7e4d0c9bf	Fix journal dirty_start position tracking and some debug prints ... Fixes two bugs found during HDD testing :-) 1) OSD crashed with "BUG: Attempt to overwrite used offset of the journal" during `fio -bs=900k -iodepth=128` test with 16 MB journal 2) OSD stalled during `fio -bs=512k -iodepth=128` test with 64 MB journal	2023-07-09 01:17:55 +03:00
Vitaliy Filippov	161a23c966	Support reloading state when etcd says "revisions were compacted" ... Before this change, OSDs almost always died when one of the etcds was restarted, even though the rest of them was still in quorum and the lease was still active	2023-07-07 01:33:48 +03:00
Vitaliy Filippov	45c0694853	Clear etcd_local addresses on reload and also skip duplicates	2023-07-06 00:39:39 +03:00

Allow deletions in unclean cluster at the cost of some data possibly "reappearing" when those OSDs start back. In that case you can just repeat the deletion request using rm-data. - A bunch of bug fixes for snapshots: - Fix snapshot reads often not working at all with snapshot chain size > 2 - Fix optimized snapshot data merge (children to parent) - Fix updating of image name index key during optimized merge - Fix auto-selection preventing the use of optimized merge with only 1 snapshot - Fix incorrect CAS retries during snapshot merge - Fix snapshot merge progress reporting - Fix primary_read bitmap buffers use-after-free which could lead to incorrect allocation map reads - Remove /usr/local/bin path from make-etcd - Some documentation fixes	2023-07-01 00:25:58 +03:00

Vitaliy Filippov	926be372fd	Release 0.9.2 ... - Measure and report scrub I/O statistics in vitastor-cli status - Make aggregated statistics in vitastor-cli status much smoother (first derive, then sum instead of first summing and then deriving) - Fix an old rare bug leading to journal corruption (try to use scrub if you think you're affected...) - Do not start EC PGs without at least <data chunks> OSDs in each old set (prevents spurious read errors with EC during reconnections/restarts) - Fix failed assert(!scrub_list_op) on OSD restart with pending scrubs - Fix future planned scrubs not starting because of incorrect time comparison - Build packages for Debian 12 (Bookworm)	2023-06-18 19:44:33 +03:00

Vitaliy Filippov	4fdc49bdc7	Add another assert-type check (it does not fire, just as a safety measure for the future)	2023-06-17 00:07:22 +03:00
Vitaliy Filippov	86b4682975	Put get_trim_pos into the "critical section". Fixes rare journal corruption issue ... The consequence of this issue was that in some very rare cases (only reproduced under load in CI when running 4+ tests in parallel) small write data written to journal could overwrite journal entries. Also add an assert-type safety check to be able to catch this issue in the future again in case of a regression.	2023-06-17 00:06:42 +03:00

Vitaliy Filippov	81fc8bb94c	Release 0.8.4 ... New features: - Implement QCOW2 image/snapshot export via qemu-img (bdrv_co_block_status in the driver) - Remove OSDs from PG history during `vitastor-cli rm-osd` to prevent `left_on_dead` PG states after deletion - Add a new recovery_pg_switch setting to mix all PGs during recovery, to almost fully reduce the probability of ENOSPC during rebalance - Introduce partial ENOSPC ("OSD is full") handling - now ENOSPC doesn't turn into cascades of crashes - Add migration support to Proxmox VE Vitastor driver - Track last_clean_pgs on a per-pool basis thus reducing data movement in a cluster with pools remaining unclean/degraded for a long time Bug fixes: - Fix a bug where monitor could generate degraded PGs if one of the hosts had no OSDs - Fix a bug where monitor could skip PG redistribution with a lot of OSDs in cluster - Report PG history synchronously on the first write, which improves PG consistency and availability at the same time, because history now gets reported correctly and doesn't get reported without the need for it - Fix possible write and recovery stalls which could happen in a cluster with both EC and replicated pools - Make OSD and monitors sanitize & deduplicate PG history items in etcd - Fix non-working OSD peer config safety check - Fix a rare journal flush stall where flushing wasn't activated with full journal, but with empty flush queue - Fix builds without ISA-L (jerasure-only) crashing with EC N+K, K>=2 due to the lack of 16-byte buffer alignment - Fix a possible crash for EC N+K, K>=2 when calculating a parity chunk with previous parity chunk missing - Fix a bug where vitastor-disk purge with suppressed warnings didn't work	2023-01-13 23:59:54 +03:00

Vitaliy Filippov	e950c024d3	Do not sync peer OSDs before listing ... Sync before listing was added to wait for all PG writes possibly left in queue from the previous master to finish before listing it But in fact it may block the cluster when EC is used and some unstable writes are left in the queue - they block journal flushing, rollback/stabilize is required to unblock them, but rollback/stabilize may only happen after PG is peered. But peering needs listings, listings are requested only after sync, and sync itself waits for currently blocked writes waiting in the queue	2023-01-03 00:05:45 +03:00

Vitaliy Filippov	a4dfa519af	Report PG history synchronously during write ...

Vitaliy Filippov	1d80bcc8d0	Fix blockstore returning garbage for unstable reads if there is an in-flight version ... "In-flight" versions are added into dirty_db when writes are enqueued. And they weren't ignored by subsequent reads even though they didn't have data location yet. This bug was leading to test_heal.sh not passing sometimes with replicated setups.	2022-12-21 02:48:24 +03:00

Vitaliy Filippov	5464821fa5	Final fix for the lack of zeroing out of old metadata entries ... If a crash occurs during flushing a redirect-write it may happen so that the disk contains both old and new metadata entries. This is OK, but prior to 0.8.0 after this situation OSDs started without problem, but then they crashed after some more overwrites with a "tried to overwrite non-zero metadata entry" error. 0.8.0 introduced a change that was intended to fix this situation, but rather than fixing it it prevented OSDs from starting, now because of a "big_write journal_entry was allocated over another object" error... :-) This change finally fixes the original issue.
