Hi all, I'm interested to know if it is possible to check the amount of free space _inside_ a LV. I know that usually a LV is fully "occupied" by a partition, but there is a (short) period when there is a gap between the size of the partition and the size of the LV it resides on. That happens _after_ doing a lvextend and _before_ doing the resize (expand) of the filesystem. First thing I thought of was lvdisplay. While I can see how many LEs the LV has, I cannot see how many of them are in use by the filesystem and how many are free (the way pvdisplay shows total/free/allocated PEs). It was suggested to me that I try some filesystem tools (resize2fs, dumpe2fs, tune2fs etc.) that might show me the free space. resize2fs does not have a 'dry-run' option that would have shown the new size (in blocks) of the filesystem and I didn't find anything useful in tune2fs' manual either. dumpe2fs shows various information such as block count, free blocks and block size, but I see no modifications when running this before and after the lvextend command. I also tried parted -l, but to no avail. _______________________________________________ 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/
