More or less the same here. My patch is much more rudimentary: it consists simply in ignoring snap_used: - space_used = data_used + snap_used + space_used = data_used The concept of your patch is correct, and to my knowledge is a good candidate for the final one. For thin lv inside a thin pool the snap_percent column value should not have a role in free space calculation inside the pool. bye rob _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
