After sourcing a new backup store and backing up the live data, we've
updated the server and rebooted. On mount errors were reported with the
filesystem so e2fsck used. Some errors were found and fixed, remounted,
no errors. First attempted write to the volume (a simple save of new
text file)
Additional: a 3rd SAN/VM pairing, part of the same wave of installation and in
most respects an identical set up is not experiencing this issue - however this
one was completed earlier in cycle so has a different kernel:
# uname -a
Linux oandata1 4.4.0-45-generic #66-Ubuntu SMP Wed Oct 19
We're seeing errors very similar to this on 2 16.04 VMs, both attached
to different SANs. Sadly one is the live data and the other the backup,
so...

We picked this up in Vivid (15.04) via a rebase to 3.18.7 and as already

Sent to ML for 3.18 since this is high priority. Since we'll rebase on
3.19 for vivid, we'll pick it up there anyway.

Once it lands in Linus' tree, I'll backport it into appropriate Ubuntu
kernel version.
