Hi,

i've just solved the problem :-P
up2date has changed my lvm.conf ....
I'm new to Centos, and i didnt know that it saves a copy of the replaced
file ....
im my case it was the lvm.conf.

The new file (called "bad" :-)  ) uses type 2 of locking_type ....

below is a short version (cutting the comments and line numbers) of a
diff between both files ....

(root at backupsrv) lvm # diff -ru lvm.conf  lvm.conf.bad

+    library_dir = "/usr/lib"
+    locking_library = "liblvm2clusterlock.so"

-    locking_type = 1
+    locking_type = 2


Thanks anyway,

Nick
