I'm noticing the following lines in dmesg when an XFS volume is being mounted
dm-1: Disabling barriers, trial barrier write failed
Anyone know what this means?
You should modify the mount options. Add
To mitigate the risk of data corruption during power loss, some storage devices use battery-backed write caches. Generally, high-end arrays and some hardware controllers use battery-backed write cached. However, because the cache's volatility is not visible to the kernel, Red Hat Enterprise Linux 6 enables write barriers by default on all supported journaling file systems.
