Vitastor 2.0.0 released

No breaking features, it’s 2.0.0 just because it includes S3 and because there are already too many 1.x releases :).

Vitastor 1.11.0 released

New features

• Support containerized Vitastor installations: http://vitastor.io/en/docs/installation/docker.html
• Add new functions to the node.js binding: delete(), get_immediate_commit(), on_ready(), get_min_io_size(), get_max_atomic_write_size()
• S3 (Zenko Cloudserver with Vitastor support) is coming shortly and will be released separately

Vitastor 1.10.1 released

New features

• Add “deleted” image flag which is set when vitastor-cli rm starts to delete an image, but can’t delete it fully due to inactive PGs or stopped OSDs
• Support JSON output in vitastor-disk prepare and purge
• Show backfillfull pools in vitastor-cli status
• Make object listings consistent (used in vitastor-cli rm/rm-data/merge/etc). This means that there is now a guarantee that if a data block is present when you invoke rm, rm will attempt to delete it, even if rm is invoked when the PG switches state. Previously in such cases rm could skip and leave some objects behind as garbage, and merge probably could incorrectly move data between snapshots.
• Make deletions (rm/rm-data) consistent. This means that rm/rm-data will either complete successfully and delete all requested image data or complete with an error if some objects could not be deleted or if there is a possibility that some data is left on stopped OSDs. Previously, when some PGs or OSDs were inactive at the moment of deletion, rm-data was behaving incorrectly: it wasn’t retrying deletions failed due to dropped OSD connections, it could hang waiting for PGs to activate, and it could return with a successful error code while some garbage was still possibly left on some OSDs. Deletions are not fully atomic cluster-wide yet, which means that you still have to repeat the deletion request after you return stopped OSDs back, but now you always know for sure if you have to repeat it.

Vitastor 1.8.0 released

Bugfix release, would be 1.7.2, but etcd layout changes mandate it to be 1.8.0. :-)

• Change etcd layout: /config/pgs is now /pg/config, /pg/stats/* is now /pgstats/*. This is required to fix a rare PG history tracking issue caused by non-atomic delivery of etcd events sometimes resulting in incomplete objects in EC pools after mass OSD restarts. Upgrading can be performed freely, downgrade requires additional action: 1.8.0 to 1.7.1
• Fix a rare client hang on PG primary OSD switch
• Fix vitastor-nfs started using mount command sometimes not stopping automatically after unmount
• Fix vitastor-nfs mounts started using mount command sometimes hanging after daemonizing
• Fix merge/flatten into a pool with different object size (image migration between pools case)
• Do not print extra “PG disappeared after reload” verbose log messages for non-existing PGs
• Fix clustered Antietcd support and persistence filter
• Do not try to purge the same OSD multiple times if its multiple devices are passed to purge
• Various node.js binding fixes

Vitastor S3 prototype based on Zenko CloudServer

The prototype of S3 Vitastor backend for Zenko CloudServer is now running 😊

This is of course far from being a release, it lacks at least defragmentation. But you can already try to run it and write/read something to it via S3. It’s even usable with GeeseFS. 😊

So, here are the instructions!
