Cause

After hardware node's reboot some ploop containers were started prior to pfcache startup. Ploop container holds reference to pfcache mountpoint and directory. Later pfcache creates new mount over existing one (that hides old directory) and userspace starts to use new directory for pfcache. But already started ploop containers are not aware and still try to search files in the old directory, fail and generate a lot of warning messages.

Issue is recognized as a product bug with internal ID #PSBM-33858.

Resolution

The fix is included in Virtuozzo (formerly Parallels Cloud Server) 6.0 Update 9 Hotfix 9 (6.0.9-2834)
