	All of the above procedures may take a considerable amount of time depending on the amount of data, so it might be advisable to execute them in a terminal multiplexer like <code>screen</code> or <code>tmux</code> or wrap them into small SLURM jobs with <code>sbatch --wrap="<command>"</code>.

			<b>Question</b>:</br> I totally lost overview, how do i find out where my files are located?

			<b>Answer</b>:</br>
			* Use <code>lfs find</code> to find files on a specific pool. Example:
			<pre>
			$> lfs find . --pool project # recursively find all files in the current directory whose file objects are on the "project" pool
			</pre>
			* Use <code>lfs getstripe</code> to query the striping pattern and the pool (also works recursively if called with a directory). Example:
			<pre>
			$> lfs getstripe parameter.h
			parameter.h
			lmm_stripe_count: 1
			lmm_stripe_size: 1048576
			lmm_pattern: raid0
			lmm_layout_gen: 1
			lmm_stripe_offset: 44
			lmm_pool: project
			obdidx objid objid group
			44 7991938 0x79f282 0xd80000400
			</pre>
			shows that the file is striped over OST 44 (obdidx) which belongs to pool project (lmm_pool).
