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.
