I'm trying to be very specific in the global_filter of lvm.conf and ignore devices under /dev/mapper of the format '^/dev/mapper/[a-z0-9]{14}$', however the repetition count '{14}' does not seem to be honored? Currently I have to repeat '[a-z0-9]' fourteen times, which works but it's a bit ugly. Does the filter use some standarized regex format? -- Thanos Makatos _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
