Maybe an idea to add a cache volume to the LV?? Not 100% sure if this works but would be nice to try.

Hello,I played around with the new dm-integrity integration in lvm. Unfortunately, itis very slow, as the checksums has to be written and read on - which is theprice to pay obviously.I thought that it might be a good idea to move the metadata to a fast disk,i.e., a SSD, however that is not possible and I get an error message on pvmove:# pvmove -n r10_int_rimage_0_imeta /dev/sdd /dev/sda2Unable to pvmove device used for raid with integrity.I could not find a reason why this should not be done in theory, thus I guessthat this is simply not supported by LVM right now?Or is there another reason why you should keep the metadata always on the samedevice?Best,Sebastian_______________________________________________linux-lvm mailing listread the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
