Hi Rafael

Everything was working ok until just before I had done the reboot - the 
seeming first problem was Windows clients having permission issues 
writing to the folders on ocfs2 filesystem, then the reboot led to the 
no free space messages.

DRBD has had no issues so far, and having brought the server down for a 
period of time I was still able to re-sync ok despite the ocfs2 
problems, although that sync didn't affect the file system on the remote 
server. I haven't tried to deploy any other file system types, so that's 
a test I will do today.

Here's the apt log for 8th September:

You can see that the newly installed kernel header/modules/image are 
5.4.0-47 and the ones I got rid of by autoremove were 5.4.0-42. However, 
there was an unattended upgrade on 3rd Sept in which 5.4.0-45 had been 
installed, so this is likely the previously used kernel version.

I'll report soon on the alternative file system as well as booting to 
the previous kernel version.
