[Parted-maintainers] Bug#399046: parted: Assertion failed (block < EXT2_SUPER_BLOCKS_COUNT(fs->sb))

[Peder Chr. Norgaard]

Package: parted
Version: 1.7.1-2.1
Severity: normal

This is data about the device:

When issuing this command

(parted) resize 1 63 42999900

I encountered the following situation:

Assertion (block < EXT2_SUPER_BLOCKS_COUNT(fs->sb)) at
../../../../libparted/fs/ext2/ext2.h: 226 in function
ext2_is_data_block() failed

The operation was conducted from the Debian etch beta 3 installation
disk, used as rescue disk.  I can add that the partition had been
fsck'ed immediately before the operation, so it is probably not a bug in
the file system.  The file system survived the operation, but the
partition was not extended as planned.

The error message urge me to file the bug directly at gnu.org; for a
Debian user I suppose it is acceptable to report to debian and expect the
maintainer to forward the message to upstream?  I did check the web page
for parted, and this particular assertion was not mentioned anywhere.
