Hi all, I would like to know if there is any means currently to know the complete geometry of a LVM volume. e.g, If a volume has 3 PV(targets). So, we should be able to extract some information like. Name of Volume. Name of Volume Group. Name, Range and size for each of the Physical devices involved. I execute the following steps. 1. pvcreate /dev/sda5 /dev/sda6 2. vgcreate vg /dev/sda5 /dev/sda6 3. lvcreate vg -L 5G So, I should see the information like. lvol0 vg target1 - /dev/sda5 ---- 0 -- 10000 ( BEGIN -- Length ) target2 - /dev/sda6 ---- 10001 -- 4000 We do maintain these informations inside the kernel, We should atleast have an ioctl or sysfs based interface to extract these information. Liblvm is under development, won't it be of a good use to provide such a functionality. Kindly suggest. -- Regards, Sandeep. “To learn is to change.
