The error 5 message repeats continuously.
I am running Centos 7. The filesystem is on a logical volume which
resides on a volume group made up of 3 software raid devices.
Any help would be greatly appreciated. Thanks.

The by count/block number btrees disagree.
These kinds of problems are difficult since the problem does not
manifest itself until the extent is removed.
Is this a new or old filesystem?
What other versions of Linux did you run on this filesystem.
Has there been storage errors?
Has it had a forced shutdown before?
Ever a problem that required log replay?
I would like to look at the metadata dump if you are willing. It should
give a better why it failed but the how may still be elusive.
(After the metadata dump,) you will need to run "xfs_repair -L" to fix.
