[ovirt-devel] Re: Status update on "Hyperconverged Gluster oVirt support"

Hi, Gobinda, great work! One thing though - the device names (sda, sdb etc..) On many servers, it's hard to know which disk is which. Lets say I have 10 spinning disk + 2 SSD's. Which is sda? what about NVME? worse - sometimes replacing disks replaces the sda to something else. We used to have the same problem with NICs and now this has been resolved on CentOS/RHEL 7.X Could the HCI part - the disk selection part specifically - give more details? maybe Disk ID or WWN, or anything that can identify a disk?

Also - SSD caching, most of the time it is recommended to use 2 drives if possible for good performance. Can a user select X number of drives?
