I've been having a problem where sometimes, creating a new partition (parted mkpart) using GPT disk label causes the block device for the previously created partition to disappear. Here is an example: http://pastebin.com/f3acd536 You can see on line 15 that after the previous parted command, /dev/sda3 which existed on line 12 is gone. There are no messages in dmesg and the partition itself is still on the disk.=20 I am working on an automated partitioning too, and so I have seen this happen with a variety of partition layouts, disks and servers (although in slightly different ways each time). I have tried putting space between partitions, time between partition commands and other methods to no avail. A few hints on where to even begin debugging this would be great!
