From 28e0fa894cd5996d3007ce82f07226f79beb7286 Mon Sep 17 00:00:00 2001 From: Dave Kleikamp Date: Mon, 20 Jun 2011 10:32:46 -0500 Subject: jfs: Update agstart when resizing volume A comment indicates that the IAG's agstart does not need to be updated since it will always point to a block in the same aggregate group, but jfs_fsck isn't so forgiving and reports it as an error. I'm fixing this in jfsutils as well, so either a new kernel or new utilities will be sufficient to fix the problem.
