Thanks. Thats nice. So mounting via UUID ensures right
drive-mount-point mapping.

 Hello List,


 does one has to use the real device names in ring-building, like:
 swift-ring-builder account.builder add z5-10.0.6.204:6002/sda4 100
 Here it is sda4.

 Can one use the partition UUID value or the mount point?
 
 It's really a mount point, not a device name. You can use whatever thing
 you want, so long as /srv/node/$thing is where the filesystem is mounted.

[Openstack] ring building absolut drive names

What if a drive has a fialure and a reboot of the system is done with
this failing drive. The subsequente drives after the failing drive will
move up with there drive letters, right? Won't this get the relations
between ring and drives mixed up?


Thank you for hints, Axel
