I'm installing a system based with install media based on 2.6.19 and mkfs.xfs 2.8.11 (its Gentoo 2007.0). That mkfs.xfs is old so i copied over a 2.9.4 binary and used that to mkfs the filesystem but its unmountable. Removing the lazy-count=1 option makes it mountable. Is this an expected incompatibility or is mix-n-matching xfsprogs a bad idea? Thanks!
