3.8 Upgrade to 3.10

[Lindsay Mathieson <lindsay.mathieson@xxxxxxxxx>]

Currently running 3.8.12, planning to rolling upgrade it to 3.8.15 this weekend.

• debian 8
  
• 3 nodes
  
• Replica 3
• Sharded
• VM Hosting only

The release notes strongly recommend upgrading to 3.10

• Is there any downside to staying on 3.8.15 for a while longer?
• I didn't see anything I had to have in 3.10, but ongoing updates are always good :(

This mildly concerned me:

• Expanding a gluster volume that is sharded may cause file corruption

But I have no plans to expand or change the volume, so shouldn't be a issue?

Upgrading

• Can I go straight from 3.8 to 3.10?
• Do I need to offline the volume first?

Thanks
