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	272a45ad63	Fix modprobe command in docs	2023-07-27 23:57:02 +03:00
Vitaliy Filippov	25a15d24cf	Fix incorrect EC space statistics in `vitastor-cli status`	2023-07-27 02:26:17 +00:00
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	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

Vitaliy Filippov	1c10430ae1	Release 0.9.4 ... - Improve QEMU driver performance by integrating io_uring in it (up to 1.5x total iops improvement) - Fix QEMU driver deadlocks which started to reproduce in qemu-img after iothread fixes - Fix `vitastor-cli status` reporting more etcds than actually exists (fix etcd address duplication in config on reload) - Fix `vitastor-cli ls` crashing on inodes in non-existing pools - Delete old garbage /pool/stats/ keys for non-existing (deleted) pools - Reduce memory usage of etcds initialized by make-etcd script - Fix OSDs almost always crashing on etcd restart due to "revisions were compacted" (support reloading state from etcd) - Fix a crash and a stall possible mostly in HDD setups with small journal and big (512k, 900k) random writes - Add notes about HDDs to documentation. You are officially allowed to use HDD-only Vitastor with HGST/Toshiba/EXOS :)	2023-07-19 02:50:30 +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	b7e4d0c9bf	Fix journal dirty_start position tracking and some debug prints ...

Vitaliy Filippov	2f999d8607	Reduce etcd memory usage ... With default --snapshot-count 100000 and GOGC=100 it easily reaches 6.6 GB even when we only store 1-2 MB of data in it	2023-07-06 00:46:26 +03:00

Vitaliy Filippov	a612cdca47	Release 0.9.3 ... - Add patch for libvirt 9.0 - Add support for Proxmox VE 8.0 - Fix compatibility of the QEMU driver with iothread (QEMU rebuilds are coming) - Fix vitastor-cli rm-data/rm/merge hanging when some OSDs are down. 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
