Instead of rsyncing on the local machine, I ran the rsync from another cluster member who also mounts the same partition I was trying to move things too. So instead of rsync -a /path/to/files/ /mnt/http/ I used rsync -a root@xxxxxxxxxx::/path/to/files/ /mnt/http/ and I didn't have a crash at all. Why would this not cause a problem when the first one did? Is this more of an rsync problem maybe? I do have 2 NFS exports, could those have been causing the problem? Thanks.
I am now seeing other crashes. Here's one from this weekend. It's huge and I'm not even sure how to see where things might have gone wrong. At the time of the crash the system was doing a backup to the gnbd server (if that helps). I'd also appreciate it if maybe someone could explain how to read this as far as where the problem actually started. Thanks again.
