The .zfs control directory implementation currently relies on the fact that there is a direct 1:1 mapping from an object id to its inode number. This works well as long as the system uses a 64-bit value to store the inode number. Unfortunately, the Linux kernel defines the inode number as an 'unsigned long' type. This means that for 32-bit systems will only have 32-bit inode numbers but we still have 64-bit object ids. This problem is particularly acute for the .zfs directories which leverage those upper 32-bits. This is done to avoid conflicting with object ids which are allocated monotonically starting from 0. This is likely to also be a problem for datasets on 32-bit systems with more than ~2 billion files. The right long term fix must remove the simple 1:1 mapping. Until that's done the only safe thing to do is to disable the .zfs directory on 32-bit systems. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> |

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./configure
$ make pkg
