If I start with a pool like this: lvs --all --segments -o +chunksize,discards LV VG Attr #Str Type SSize Chunk Discards pool1 vg1 twi-a-tz- 1 thin-pool 100.00m 64.00k passdown [pool1_tdata] vg1 Twi-aot-- 1 linear 50.00m 0 [pool1_tdata] vg1 Twi-aot-- 1 linear 50.00m 0 [pool1_tmeta] vg1 ewi-aot-- 1 linear 2.00m 0 My first question is if I look at "pool1" with liblvm2pp will there ever be more than one segment? I know "pool1_tdata" can have more but it looks like "pool1" is just one. My second question is if discards and chunksize are segment properties, can a pool have more than one setting of either? Thank you. Thank you. _______________________________________________ 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/
