Dear list,

I'm with debian wheezy with lvm2 2.02.95-4.

whenever I try to execute lvcreate it fails. Here is the output of such
a command

``````````````````
#lvcreate -v -n root -L 80G mygroup

Setting logging type to disk
Finding volume group "mygroup"
Archiving volume group "mygroup" metadata (seqno 7).
Creating logical volume root
Creating volume group backup "/etc/lvm/backup/mygroup" (seqno 8).
Found volume group "mygroup"
activation/volume_list configuration setting not defined: Checking only host tags for mygroup/root

Resuming mygroup-root (254:1)
Clearing start of logical volume "root"

Aborting. Failed to wipe start of new LV.
Found volume group "mygroup"
Removing mygroup-root (254:1)
Creating volume group backup "/etc/lvm/backup/mygroup" (seqno 9).

Failed to set a proper state for notification semaphore identified by cookie value 223206764 (0xd4ddd6c) to initialize waiting for incoming notifications.
`````````````````````````

Am I missing anything ?

Thanks

-Z, --zero y/n
Controls zeroing of the first KB of data in the new logical volume.
Default is yes.


Warning: trying to mount an unzeroed logical volume can cause the
system to hang.
