In dm-cache, how do you make snapshots on a cached LV? I tried the usual way on a CentOS 6.7 installation and got the following results:# lvsLV         VG          Attr       LSize   Pool          Origin             Data%  Meta%  Move Log Cpy%Sync ConvertLogVol00   vg_server17 -wi-ao---- 117.19gLogVol01   vg_server17 -wi-ao----  78.12gkvm163_img vg_server17 Cwi-aoC---   1.05t [DataLVcache] [kvm163_img_corig] 10.14  12.29           0.00# lvcreate -s -n /dev/vg_server17/kvm163_img_snap -L 10G /dev/vg_server17/kvm163_img  Snapshots of cache type volume vg_server17/kvm163_img is not supported.Any advice?
