Re: [MooseFS-Users] Upgrade from 2.0.81 to 2.0.88 to 3.0.77

[web u. <web...@gm...>]

I had a old ppa in /etc/apt/source.list replaced it with
/etc/apt/source.list.d/moosefs.list with an explicit version number and
followed all the instructions

2.0.77 -> 2.089 [brought up servers] -> shutdown and backup again -> 3.0.77

Everything went very smoothly. Thanks for the awesome support and such a
rock solid product!
