When zfs_replay_write() replays TX_WRITE records from ZIL it calls zpl_write_common() to perform the actual write. zpl_write_common() returns the number of bytes written (similar to write() system call) or an (negative) error. However, the code expects the positive return value to be a residual counter. Thus when zpl_write_common() successfully completes it is mistakenly considered to be a partial write and the error code delivered further. At this point the ZIL processing is aborted with famous "ZFS replay transaction error 5" error message given to the message buffer. The fix is to compare the zpl_write_commmon() return value with the buffer size and flag error only when they disagree.

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
