The lustre zpios-test simulates a reasonable lustre workload. It will create 128 threads, the same as a Lustre OSS, and then 4096 individual objects. Each objects is 16MiB in size and will be written/read in 1MiB from a random thread. This is fundamentally how we expect Lustre to behave for large IO intensive workloads.
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
