Vitastor 0.6.9 released

2021-12-03

New features

  • Build Vitastor driver as part of QEMU
  • Implement renaming images in CLI (vitastor-cli modify --rename)
  • Add vitastor-cli alloc-osd and simple-offsets commands and use them in make-osd, thus removing the dependency on etcdctl
  • Make monitor remove stale deleted inode statistics from etcd automatically
  • Implement OSD address selection from a subnet, thus removing the need to specify OSD addresses in startup scripts explicitly

Bug fixes

  • Fix client failover in case of etcd shutdown or crash (make client survive etcd failures)
  • Stick to the last live etcd in OSD and mon to prevent random failures when one of etcds is down
  • Fix incorrect copying of data from journal to the data device which could lead to data corruption
  • Prefer local etcd IPs in OSD
  • Remove the total PG count restriction in optimize_change which was sometimes leading to inability to redistribute PGs over OSDs
  • Fix error response parsing on a failed pg state report
  • Fix slow linear writes with RDMA by changing default buffer settings
  • Fix bugs in vitastor-cli create, ls, rm, modify commands

Patch changes

  • Add a patch for libvirt 7.6
  • Add patches for QEMU 6.0 and 6.1
  • Fix config file path XML location parsing in libvirt patches
  • Replace _ with - in QEMU options
  • Fix possible ‘TypeError’ in OpenStack Nova when using Vitastor Cinder driver
  • Fix possible crashes of QEMU block driver in case of incorrect options
