Actually I have one last idea. My nodes are installed from standard
Debian "stable" repos. That means they're version 3.8.8 !
I understand it's an ancient version.
What's the recommended upgrade path to a current version? Possibly
keeping the data safe: I have nowhere to move all those TBs to...
I am not aware of any data layout changes we did between current latest (7.7) and 3.8.8. But due to some issues, 'online' migration is not possible, even the clients needs to be updated, so you have to umount the volume once.

Amar
