From 5383ef3a929a1366e2ced45cd6d74be7aa2a2281 Mon Sep 17 00:00:00 2001 From: Joe Thornber Date: Wed, 4 Dec 2013 16:30:01 -0500 Subject: [PATCH] dm thin: re-establish read-only state when switching to fail mode If the thin-pool transitioned to fail mode and the thin-pool's table were reloaded for some reason: the new table's default pool mode would be read-write, though it will transition to fail mode during resume. When the pool mode transitions directly from PM_WRITE to PM_FAIL we need to re-establish the intermediate read-only state in both the metadata and persistent-data block manager (as is usually done with the normal pool mode transition sequence: PM_WRITE -> PM_READ_ONLY -> PM_FAIL).
