+== Stripe Pattern Details ==
+
+It is possible to query this information from the deep login node, for instance:
+
+{{{

+Path: /manzano
+Mount: /work
+EntryID: 1D-53BA4FF8-3BD3
+Metadata node: deep-fs02 [ID: 15315]
+Stripe pattern details:
++ Type: RAID0
++ Chunksize: 512K
++ Number of storage targets: desired: 4
+
+manzano@deep $ beegfs-ctl --getentryinfo /sdv-work/manzano
+Path: /manzano
+Mount: /sdv-work
+EntryID: 0-565C499C-1
+Metadata node: deeper-fs01 [ID: 1]
+Stripe pattern details:
++ Type: RAID0
