The interface for the ddt_zap_count() function assumes it can never fail. However, internally ddt_zap_count() is implemented with zap_count() which can potentially fail. Now because there was no way to return the error to the caller a VERIFY was used to ensure this case never happens. Unfortunately, it has been observed that pools can be damaged in such a way that zap_count() fails. The result is that the pool can not be imported without hitting the VERIFY and crashing the system. This patch reworks ddt_object_count() so the error can be safely caught and returned to the caller. This allows a pool which has be damaged in this way to be safely rewound for import.

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
