Re: [MooseFS-users] A thorny moosefs problem by version 1.6.25

[Piotr R. K. <pio...@mo...>]

Dear Chenr,
I would like to mention, that in MooseFS 2.0.x problems with "closed by peer" connections  of course have been solved.

Please remember to backup your metadata, changelogs and configuration before doing an upgrade.

We very recommend upgrading MooseFS to 2.0.48 CE.

Dear Chenr,
We are very happy that you're using MooseFS :)

1.6.25 is a very old and not supported version of MooseFS.

You should *immediately* upgrade your whole instance to the *MooseFS 2.0.48 CE*,
because in 2.0.x branch a lot of improvements and bug fixes has been made.

Please keep in mind, that supported way to upgrade your instance is:
Your version -> *1.6.27-5* -> 2.0.x CE,

so you firstly need to upgrade to 1.6.27-5 and then to 2.0.48 CE.

The whole upgrade process is described in MooseFS Upgrade Guide[2], so please refer to this document.
I also very recommend reading MooseFS 2.0 Step-by-Step Installation Guide[3].


Also, at http://get.moosefs.com[4] you can find useful information about installing MooseFS from packages,
so now you don't need to compile MooseFS yourself (but you still can if you want, because sources of MooseFS 2.0.x CE are available).


In case of any questions, please don't hesitate to contact our Technical Support Department at dw...@mo...[5].

           I meet a thorny problem : 
all servers attached to  the same switch  ,
the network  connection between the server properly ,the  network in stable condition, but all mfschunkservers ,mfsclients  and mfsmetalogger servers  disconnected the mfsmaster on the same time,
the mfsmasterserver's log is as follows figure:
 
I can not find the cause of the problem , so restart the mfsmaster , then everything back to normal .This happens several times, after  restart mfsmaster ,all services back to normal.
