The "--raw" argument is only meaningful for directories, and has no meaning for regular files (which is the case of your original report).</p> <p>The default striping set on a directory allows "passthrough" to the filesystem-wide striping (i.e. any values which are not specified are the default). The "--raw" argument means "tell me the actual layout specified for the directory, not what it would be if a new file is created in the directory". For example (on current master):</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre># mkdir /mnt/testfs/foo # lfs getstripe /mnt/testfs/foo /mnt/testfs/foo stripe_count: 1 stripe_size: 1048576 stripe_offset: -1 # lfs getstripe --raw /mnt/testfs/foo /mnt/testfs/foo stripe_count: 0 stripe_size: 0 stripe_offset: -1 </pre> </div></div> <p>This shows that there is no default striping specified on the directory at all.</p> <p>If the stripe count is explicitly set to 3 (without changing anything else), the normal getstripe output will still show the "combined" striping, but the --raw output shows only the layout that was actually set on the directory:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>lfs setstripe -c 3 /mnt/testfs/foo # lfs getstripe /mnt/testfs/foo /mnt/testfs/foo stripe_count: 3 stripe_size: 1048576 stripe_offset: -1 # lfs getstripe --raw /mnt/testfs/foo /mnt/testfs/foo stripe_count: 3 stripe_size: 0 stripe_offset: -1 </pre> </div></div> Related LU-3898 Development Rank 1|hzw0tb: Rank (Obsolete) 10212 Severity
