Hello, I played around with the new dm-integrity integration in lvm. Unfortunately, it is very slow, as the checksums has to be written and read on - which is the price 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/sda2 Unable to pvmove device used for raid with integrity. I could not find a reason why this should not be done in theory, thus I guess that this is simply not supported by LVM right now? Or is there another reason why you should keep the metadata always on the same device?
