It is a relatively new file system. It was probably created within the last six months. It has only ever been used with Centos 7. It has been mounted with the kernel-3.10.0-229 and kernel-3.10.0-327.22.2.el7 kernels. There was a hardware issue with the power supply to a few of the physical disks that make up one of the software raid devices. A couple disks would lose power and go offline. While resolving that issue, there most likely were some hard reboots. What steps do I need to take to get you the metadata dump? Thank you for your help.
