Subject: kernel bug at fs/ext4/resize.c:409
Date: Mon, 3 Feb 2014 13:26:34 -0500 [thread overview]
Message-ID: <20140203182634.GA28811@shaniqua> (raw)
Hello all,
A coworker is seeing the following bug when attempting to resize a root
volume (during init by calling resizefs) from 1GB to the size of the
underlying partition size of 20GB.
If the partition size is changed (to i.e. 10GB), the bug seems to not
trigger. I have access to this machine, if there are any experiments
that would provide more useful information - please let me know.
