A bug has been detected in GNU Parted. Refer to the web site of parted
http://www.gnu.org/software/parted/parted.html for more information of what
could be useful for bug submitting! Please email a bug report to
[email protected] containing at least the version (3.4) and the following
message: Assertion (!disk->update_mode) at disk.c:481 in function
ped_disk_commit_to_dev() failed.
Aborted
I would thought expected if a disk cannot be used after a clobber that either
the ped_disk_commit_to_dev call would return 0.
Also, should the documentation for ped_disk_clobber state that no use of
pre-existing disks should be made after clobber has been called, and that there
is no need to commit the change as it as they appear to be committed to disk by
the call to clobber.
