Description Jeff Applewhite 2016-05-19 07:26:12 UTC 
Description of problem:
There is a risk of a node having multiple disks and losing a disk then another disk will take it's device name. 

Ex. 

/dev/sda
/dev/sdb
/dev/sdc
/dev/sdd

Now /dev/sdc fails. The host reboots. What will happen is that /dev/sdd will now have the identifier /dev/sdc which will cause problems in our handling of the disks.

Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:
1. Fail a disk. 
2. Roboot the host 
3. watch that the disks will be re-ordered


Actual results:


Expected results:
We should refer to disks by their unique id that can be found at /dev/disk/by-uuid/<uuid> because this does not change on reboot.
