Maybe it will be implemented later? But it seems to me a little strange when there is no way to clear the cache from a garbage. Maybe I do not understand? Can you please explain this behavior. For example: I have the full cached partition, with full cache: [root@localhost ~]# df -h /data Filesystem Size Used Avail Use% Mounted on /dev/mapper/test-data 12G 12G 0 100% /data [root@localhost ~]# lvs -a LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert data test Cwi-aoC--- 12.00g [fast] [data_corig] 99.72 2.93 0.00 [data_corig] test owi-aoC--- 12.00g [fast] test Cwi---C--- 1.00g 99.72 2.93 0.00 [fast_cdata] test Cwi-ao---- 1.00g [fast_cmeta] test ewi-ao---- 8.00m [lvol0_pmspare] test ewi------- 8.00m I clear the partition and do fstrim: [root@localhost ~]# rm -rf /data/* [root@localhost ~]# fstrim -v /data [root@localhost ~]# df -h /data Filesystem Size Used Avail Use% Mounted on /dev/mapper/test-data 12G 41M 12G 1% /data But the cache remained full: [root@localhost ~]# lvs -a LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert data test Cwi-aoC--- 12.00g [fast] [data_corig] 99.72 2.93 0.00 [data_corig] test owi-aoC--- 12.00g [fast] test Cwi---C--- 1.00g 99.72 2.93 0.00 [fast_cdata] test Cwi-ao---- 1.00g [fast_cmeta] test ewi-ao---- 8.00m [lvol0_pmspare] test ewi------- 8.00m Thank you.
