It recurs constantly. In the last 4 years, it has never had more than 168 days uptime and just yesterday after 68 days, it crashed again.

Just got this last night:

GFS2: fsid=: Trying to join cluster "lock_dlm", "gamma:gfs1"
dlm: Using TCP for communications
dlm: connecting to 1
GFS2: fsid=gamma:gfs1.1: Joined cluster. Now mounting FS...
GFS2: fsid=gamma:gfs1.1: jid=1, already locked for use
GFS2: fsid=gamma:gfs1.1: jid=1: Looking at journal...
GFS2: fsid=gamma:gfs1.1: jid=1: Done
GFS2: fsid=gamma:gfs1.1: fatal: invalid metadata block
GFS2: fsid=gamma:gfs1.1: bh = 58964991 (magic number)
GFS2: fsid=gamma:gfs1.1: function = gfs2_meta_indirect_buffer, file = fs/gfs2/meta_io.c, line = 401
GFS2: fsid=gamma:gfs1.1: about to withdraw this file system
GFS2: fsid=gamma:gfs1.1: telling LM to unmount
GFS2: fsid=gamma:gfs1.1: withdrawn

So, this weekend we’re going to figure a staging method to move to OCFS2.

There were a few where I knew the themes or certain plugins would break so I knew what to look for. I will probably adjust it to look for a few signatures. For the most part, 99% of them upgraded without any issues, two had problems (reported this morning), both were simple upgrade the plugin causing the problem. One was a tag plugin I had never heard of. Luckily, the older sites used very generic themes and very few plugins. They were set up, had 10-20 posts and then were probably forgotten - projects that someone would come back and handle later on. I debated upgrading anyone on 3.x, but, in the end, looked at the changes in 3.x -> 3.3.1 and determined that there would be less breakage there than from 2.0 -> 3.3. Of the older 2.x sites, pre 2.6 were checked a bit more since there were a number of changes. I did a spot check on most of them to make sure things did look right.

Where do you draw the line between appeasing clients and server security? How do you deal with clients if the upgrade has broken the site (e.g. depreciated functions or themes)?
