Another example, same machine, thin pool a thin volume inside: # lvs --units m -o lv_name,vg_name,pool_lv,size,data_percent,snap_percent LV VG Pool LSize Data% Snap% thinlv vgtest thinpool 1024,00m 9,77 9,77 thinpool vgtest 8192,00m 1,22 1,22 > bye, > rob _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
