Firstly, if you have the latest software, I suggest you switch to the smq cache policy which is generally out performing the old mq policy substantially. Secondly, I think you may need to reset your expectations a bit. dm-cache is a slow moving cache. It monitors IO, detectings hotspots on the disk and then 'promotes' those regions to the SSD. You may find that the reads that occur during a boot, occur only infrequently once the system is booted. - Joe _______________________________________________ linux-lvm mailing list [email protected] https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
