MFS CONNRESET (Connection reset by peer)

Hi!

With the below instructions you can increase timeout on chunkservers and

mfsmounts. Please give them a try and come back to us with the results.

1. csserv.c file in mfschunkserver:

// connection timeout in seconds

#define CSSERV_TIMEOUT 5

change 5 to eg. 10

2. cscomm.c file in mfsmount:

#define CSMSECTIMEOUT 5000

change 5000 to eg. 10000

Kind regards

Subject: [Moosefs-users] Question about ECONNRESET (Connection reset by

peer)

Hello

Could you please tell me in which cases there is an error:

Feb 15 18:09:25 mfsmount[2174]: readblock; tcpread error: ECONNRESET

(Connection reset by peer) Feb 15 18:09:25 mfsmount[2174]: file: 316275,

index: 0, chunk: 134391,

version: 1, cs: C0A8015D:9422 - readblock error (try counter: 3)

At rush hour, some of our servers are beginning to slow down and write to a

log of these messages.

What we need to check first? Could there be a problem with the network cards

or a problem on the switch?

We use the MFS for streaming video. All hard drives loaded with no more than

40%. On each Chunkserver idle ~ 50%.

Kind regards,
