But my goal is to build a backup script to automaticaly create a snapshot of an LV mounted somewhere. So either the volume group name or the logical volume name is unknown In my process I do a 'reverse' research to find it out. Something like that :
#mount | awk some-args #and return something like this : [...many mounted devices...] /dev/mapper/VGNAME-LVNAME /mount/point #the line i want to find ! #lvdisplay /dev/mapper/VGNAME-LVNAME | grep "VG Name" => the previous command should return the value of the VG name of my LV but... Not because it fails :) -- Guillaume -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
