Bug#274988: New crash .....
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi guys,
Just a quick update .... the machine died again today
xfs_repair is running now, hopefully should be done by the end of today
It takes a few hours
A quick thought ... There is one rsync job that takes a very long time to
complete. It's copying a database to our DR site. Takes a couple of days :(
Maybe it's holding something open for too long?
I'll continue poking around the machine to see if any clear patterns emerge
Anyways .... Onto the dumps
