Любопытно, а как там обстоят дела с кластерной файловой системой?Что вы имеете в виду?
Removing the .lck file (NFS only)
The files on the virtual machine may be locked via NFS storage. You can identify this by files denoted with .lck-#### (where #### is the value of the fileid field returned from a GETATTR request for the file being locked) at the end of the file name. This is an NFS file lock and is only listed when using the ls -la command because it is hidden file (in versions of ESX/ESXi prior to 5.x). For more information, see Powering on a virtual machine on NFS or trying to remove an NFS Datastore fails with errors «Unable to access a file since it is locked» or «Resource is in use» (1012685).
For more information on NFS file locking, see the VMware NFS Best Practices Whitepaper.
Caution: These can be removed safely only if the virtual machine is not running.
Note: VMFS volumes do not have .lck files. The locking mechanism for VMFS volumes is handled within VMFS metadata on the volume.
