According to the docs of Swift, devices in a ring are identified by disk name like "/dev/sdb1" :
devicestringThe on disk name of the device on the server. For example: sdb1 http://swift.openstack.org/overview_ring.html But such disk name would change: When one of the disks fails, all names of disk after failed disk changes. If sdb fails, sdc becomes sdb, and sdd becomes sdc.... The same when new device is added. Isn't this a problem? Or is there some internal mechanism to prevent this to happen or something like a workaround? -- 要了几天饱饭就不记得西北风啥味了
