Re: [MooseFS-Users] Upgrade Cluster

[Aleksander W. <ale...@mo...>]

Hi.

There will be no problems.
If you like you can stop whole cluster and than execute update.
You can find instruction how to stop MooseFS cluster in our
documentation, but basically this are the steps that you have to do to
stop whole cluster.

1. Umount all clients
2. Stop master
3. Stop metaloggers
4. Stop all chunkservers
