Re: [linux-lvm] Hide volume group during startup

[Erik Schwalbe <erik.schwalbe@canoo.com>]

Hi,

filter was:

filter = [ "r|/dev/data/kvm_disk0|" ]

path:
/dev/data/kvm_disk0 -> ../mapper/data-kvm_disk0

The device name is stable, but what other way of control activation are possible??

Regards,
Erik

Please post the filter you are using as well as the full path name of
the disk you are attempting to filter (a complete recursive listing of
/dev as generated by lvmdump or run by hand would be useful. You can use
a service like pastebin for this - please don't send large attachments
to the list).

There are other ways to control activation if for some reason filtering
will not work (e.g. the device name is not stable).

Bryn.
