From e4c78e210daea17f82f12037005df225e22189b9 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Wed, 15 Jul 2015 11:40:24 -0400 Subject: dm thin: display 'needs_check' in status if it is set There is currently no way to see that the needs_check flag has been set in the metadata. Display 'needs_check' in the thin-pool status if it is set in the thinp metadata. Also, update thinp documentation.
