Hello. Tell me please, how can I get the maximum address used by a virtual disk (disk created with -V VirtualSize). I have several large virtual disks, but they use only a small part at the beginning of the disk. For example: # lvs LV VG Attr LSize Pool Origin Data% mylvm CVG Vwi-aot--- 100,00g fastheap 7,13 Please advise me how to determine from which address the virtual disk did not allocate real disk space? And all the data read from addresses greater than this address will be exactly zeros. Or maybe, how can I get map of the used chunks of disk? Thanks. ---- _______________________________________________ linux-lvm mailing list linux-lvm@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
