Is it expected to leave the counters in a state where are discardable extents but not process after a long period of time? I found discard_bitmap_bytes:316833792 discard_bytes_saved:59390722048 discard_extent_bytes:26122764288 discardable_bytes:44863488 discardable_extents:883 iops_limit:10 kbps_limit:0 max_discard_size:67108864 there was activity when the number of extents wen from about 2000 to that value (833), so this could bea nother instance of the -1 accounting bug.
