The assumption in zio_ddt_free() is that ddt_phys_select() must always find a match. However, if that fails due to a damaged DDT or some other reason the code will NULL dereference in ddt_phys_decref(). While this should never happen it has been observed on various platforms. The result is that unless your willing to patch the ZFS code the pool is inaccessible. Therefore, we're choosing to more gracefully handle this case rather than leave it fatal. http://mail.opensolaris.org/pipermail/zfs-discuss/2012-February/050972.html Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #1308
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
To copy the kernel code inside your kernel source tree for builtin compilation:
$ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
$ ./copy-builtin /usr/src/linux-...
Full documentation for building, configuring, and using ZFS can be found at: http://zfsonlinux.org
