Error description
cplv command is failing while trying to copy from a 512 block disk to 4k block disk. /usr/sbin/cplv -v vg4k -y fslv02 fslv01 copyrawlv: Invalid argument 0516-743 cplv: Error occurred during data copy.
Local fix
Problem summary
cplv may fail if copying an LV without an lvcb on disk but with a filesystem from a VG with 512b block size to one with 4k block size. Typically this would be using SVG type VGs.
Problem conclusion
Correct cplv code wrt to how much it skips during cplv so that we ensure we only write in 4k chunks to the destination LV, as writing less than that is unacceptable in a 4k bs VG.
Temporary fix
