Create a kstat file which contains useful statistics about the last N txgs processed. This can be helpful when analyzing pool performance. The new KSTAT_TYPE_TXG type was added for this purpose and it tracks the following statistics per-txg. txg - Unique txg number state - State (O)pen/(Q)uiescing/(S)yncing/(C)ommitted birth; - Creation time nread - Bytes read nwritten; - Bytes written reads - IOPs read writes - IOPs write open_time; - Length in nanoseconds the txg was open quiesce_time - Length in nanoseconds the txg was quiescing sync_time; - Length in nanoseconds the txg was syncing 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
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
