I have encountered a problem that I think is related to changes made by patches in this email thread.

The problem occurs when partition and file system changes are made to a partition lower (e.g., sda1) than a mounted partition (e.g., sda2). When this occurs parted does not recognize the file system on the lower partition.

My testing used the patched version of parted-2.2 along with gparted-0.5.2 on the recently released ubuntu-10.04-beta2-desktop-i386.iso image. I was also using an msdos label.

When I create two partitions and format these, I experience no problems with parted recognizing the file system. I can also delete the first partition, then recreate the first partition and format it, and again parted is able to recognize the file systems.

However if I mount the second partition and proceed to delete the first partition, then when I recreate the first partition and format it, parted is unable to recognize the file system on the first partition.

It should be noted that the blkid command does correctly report the file system on the first partition.

The fact that the problem only appears when changes are made to a lower partition when a higher partition is mounted leads me to believe that this problem is related to the patches discussed in this email thread.

Please feel free to ask if you need more help or information to isolate this bug.

Regards,
Curtis Gedak
