** Description changed: This is on a Hewlett-Packard ProLiant DL380 G7, with a Smart Array P410i RAID controller containing a RAID 1+0 array of four SATA hard drives. It's running Ubuntu 16.04 with the linux-image-generic-hwe-16.04-edge packages installed. The root partition consists of a simple ext4 filesystem on /dev/sda1, which is on the RAID array There is a more complex secondary mount involving mdraid and bcache intended to be mounted at /srv - but we're seeing problems before that comes into play.
