I upgraded a 12.04 LTS to 14.04LTS this weekend and then applied the wily 
kernel update as mentioned in your mail.
But I had it go read/only again this morning.


[cid:23B4D2DB-61D4-4F67-8185-1CD378F4D056@hv.local]

I have attached a screen print, if you need more, please let me know.

@f-bosch, @lauwersm, we appreciate your patience. We've looked into
storvsc and vss and have been trying to reproduce the problem, and while
we seem to have lowered the occurrence of the problem, have not
eliminated it.

However, since the last storvsc update, we have fixed a number of issues
in the 3.19 and 4.2 kernels. If not for a rushed CVE, those kernels
would be GA at this point, but they are going into -proposed for release
this weekend.

Since you are on 14.04, I recommend testing on the lts-wily kernels,
especially after the update goes out.

# apt-get install --install-recommends linux-virtual-lts-wily linux-
tools-virtual-lts-wily linux-cloud-tools-virtual-lts-wily

(and reboot)

This will move you to the 4.2 kernel, and after the latest update goes
out, you will be running Hyper-V components from the 4.3 upstream
kernel.

On the next point release of 14.04, the plan is to switch the
recommended kernel to lts-wily anyway, so you are just getting ahead of
the rush a little.

 Customers have reported running various versions of Ubuntu 14.04.2 LTS
 on Generation 2 Hyper-V Hosts.On a random Basis, the file system
 will be mounted Read-Only due to a "disk error" (which really isn't
 the case here).As a result, they must reboot the Ubuntu guest to
 get the file system to mount RW again.

 The Error seen are the following:

 This relates to the VSS "Windows Server Backup" process that kicks off at 
midnight on the host and finishes an hour and half later.
 Yes, we do have hv_vss_daemon and hv_kvp_daemon running for the correct kernel 
version we have.   We're currently running kernel version 3.13.0-49-generic #83 
on one system and 3.16.0-34-generic #37 on the other. -- We see the same errors 
on both.
 As a result, we've been hesitant to drop any more ubuntu guests on our 2012R2 
hyper-v system because of this.   We can stop the backup process and all is 
good, but we need nightly backups to image all of our VM's.   All the windows 
guests have no issues of course.   We also have some CentOS based guests 
running without issues from what we've seen.
