The number of threads has nothing to do with the number of cores on the machine. It depends on the I/O, network speed, type of workload etc. We usually start with 32 threads and increase if necessary. You can check the statistics with: watch 'cat /proc/net/rpc/nfsd | grep th? Or you can check on the client nfsstat -rc Client rpc stats: calls retrans authrefrsh 1326777974 0

Hi Orion, no, I still have this problem. I delay working on it as I the latest updates have not been installed on the server and on the client. I'll work again on this problem as soon as possible. Thanks Charles for your detailed information on how to track this problem. I'll check all these metrics. I have several clients for this nfs server and the problem seems only to occur from the

Thanks Patrick. For Solaris, quota can be set when mounting from NFS client. There is a transition from Solaris to CentOS 6 this time. Therefore, quota setting is required for NFS mounting from CentOS 6 as with Solaris. Is it still impossible for CentOS 6? koji On Sun, 2 Apr 2017 14:44:59 +0200 Patrick B??gou <Patrick.Begou at legi.grenoble-inp.fr> wrote: > Quota are managed at the

Hi Barbara, Thanks for all these suggestions. Yes, jumbo frames are activated and I have only two 10Gb ethernet switch between the server and the client, connected with a monomode fiber. I saw yesterday that the client showing the problem had not the right MTU (1500 instead of 9000). I don't know why. I changed the MTU to 9000 yesterday and I'm looking at the logs now to see if the

Hi, I have a strange problem with a freshly installed Centos7 desktop (most8pc25). I can't ssh to 2 CentOS6 servers, even with firewall disabled on the client and on the server. But I can connect from the server to the client, all in the same VLAN. I can also ssh from this desktop to centos7 servers in the same VLAN or in another VLAN. No idea about this problem. On the server kareline

I'm very confused on the right step to use to setup a modified kernel in centOS6. As a simple user, I've downloaded the latests sources (I'm runing an old kernel version) : rpm -i http://vault.centos.org/6.7/updates/Source/SPackages/kernel-2.6.32-573.22.1.el6.src.rpm in the spec file ~/rpmbuild/SPECS/kernel.spec I've set: %define buildid .numa Now I want to set

Hello I have more and more troubles using firefox in professional environment with CentOS6. The latest version is 45.7.0 But I can't use it anymore to access some old server hardware (IDRAC7 of DELL C6100) because of "/SSL_ERROR_WEAK_SERVER_CERT_KEY/". I had to install an old Firefox32 version to administrate these servers. Today I upgrade the firmware of 2 DELL switch and now
