LVM test result with IDM lock manager

  • 8 cases are caused by cannot find drive path cannot achieve majority:
  activate-missing-segment.sh
  large-physical-sector-size.sh
  lvchange-partial-raid10.sh
  lvchange-partial.sh
  mirror-vgreduce-removemissing.sh
  profiles-thin.sh
  topology-support.sh
  vgchange-partial.sh
  • 4 cases are dependent on big disk.
  lvconvert-cache-chunks.sh
  lvcreate-large-raid.sh
  profiles-cache.sh
  thin-large.sh
  • Updated: new failure cases for upstreaming LVM2
  cache-single-split.sh
  lvcreate-thin-limits.sh
  metadata-full.sh

Comparision with sanlock lock manager

There have 8 cases in LVM which cannot pass with IDM lock manager, for more confidence, below is the checking for these 8 cases with sanlock lock manager, and all of them fail with sanlock as well. This can give us more confidence for the testing result.
