[MooseFS-Users] Connect attempts to offline chunk server

[Alexander A. <ba...@ya...>]

Hi guys!

I have a very strange situation (in my opinion).

I am building a new Moose cluster. By now I have just 2 chunk servers.

So when one of them is offline MFS client still tryes to connect to it!

I see it using tcpdump running on MFS client.

It is strange because MFS master knows  about  offline chunk server 
(shown as "Disconnected Chunk Servers" on Web-CGI page)

and it is surprise for my why master points client to the dead chunk server.

So because of such attempts I have a HUGE !!!!!!! performance 
degradation and it stops me from running MooseFS in production.

It there any workaround or fix? Many thanks!

My environment:

MFS version: 3.0.99

Master OS:

# uname -a
FreeBSD mfs-master-1 11.1-RELEASE-p4 FreeBSD 11.1-RELEASE-p4 #0: Tue Nov 
14 06:12:40 UTC 2017 
ro...@am...:/usr/obj/usr/src/sys/GENERIC amd64

Chunk server and client OS:

# uname -a
Linux proxmox-2 4.13.13-5-pve #1 SMP PVE 4.13.13-36 (Mon, 15 Jan 2018 
12:36:49 +0100) x86_64 GNU/Linux
# cat /etc/debian_version
