similar to: Boot fails with lvm snapshot

Hi Gordon, my dracut package is the latest available for Centos7 (this occur just after my "yum update" and reboot). It is dracut-033-568.el7.x86_64 in CentOS Linux release 7.8.2003 (Core) I'm going to rebuild my initrd as suggested with the snapshot setup. Thanks for the links.

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

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

Hello. I am "koji". I have a question. Can I mount a NFS with quota? (Not Server side) I understand quota is set NFS server. But I must client side. (Is rquota only report?) Does anyone know a good solution? Best regard. koji

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

Hi, I need some help with NFSv4 setup/tuning. I have a dedicated nfs server (2 x E5-2620? 8cores/16 threads each, 64GB RAM, 1x10Gb ethernet and 16x 8TB HDD) used by two servers and a small cluster (400 cores). All the servers are running CentOS 7, the cluster is running CentOS6. Time to time on the server I get: ?kernel: NFSD: client xxx.xxx.xxx.xxx testing state ID with incorrect

So I have two CentOS 7 machines running. if I am on my server and I do "curl http://192.168.1.8" I get data. If I do "host devgeis.LayeredSolutionsInc.com" I get the correct address 192.168.1.8 if I goto another machine with CentOS 7. I do "curl http://192.168.1.8" I get data. I do "host devgeis.LayeredSolutionsInc.com" I get the correct address

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 have just installed (with kikstart) centOS6.4 on a PC which was previously running OpenSUSE (11.x). This PC has an apple keyboard and I'm unable to setup this keyboard. In .xsession-errors I get this messages : Error: No Symbols named "latin9" in the include file "macintosh_vndr/fr" Exiting Abandoning symbols file

I'm working with some people using apple laptops. When we share text files (latex files), I reach in an encoding problem on our CentOS laptops and desktops. In my favorite editor, "?" is "<8e>", "?" is "<88>" etc... Of course, I can change the encoding with iconv: iconv -f MACINTOSH -t ISO8859-15 file.bib.mac >file.bib iconv -f
