...posed of 8 nodes, connected via fibre channel, to a raid enclosure where we have 6 pair of 1-tb drives in mirror, so 6 1tb physical volumes. First of all, our services that are run from the cluster are running inside of directories. For exemple, a webserver for a given application is run from /CyberCat/WebServer/(...) That directory contains all executable (apache, php for exemple) and the related data, except for the databases. /CyberCat being a single GFS partition containing several other services. This filesystem and another one like this containing services for some other clients occupy...

5.6 is out. That is good news. I did a yum update on one of my non-critical server, and the server stoped responding to ping after the reboot, and never answered back.

I have a server where /home is on a nfs. I installed an apache (my compile) server. By default, it runs as daemon. That user can't acces files in /home/*/public_html, while the nobody user can. So if I change my apache config, it now can. /home is : drwxr-xr-x /home/user is : drwxr-xr-x /home/user/public_html is : drwxr-xr-x selinux is disabled. In the error log of apache I get :

Hi list ! We have a very busy webserver hosted in a clustered environment where the document root and data is on a GFS2 partition off a fiber-attached disk array. Now on busy moments, I can see in htop, nmon that there is a fair percentage of cpu that is waiting for I/O. In nmon, I can spot that the most busy block device correspond to our gfs2 partition where many times, it shows that

On a ldap enabled CentOS 6.3 x64 system, I try to make it so home directories are auto-created. I added this : session required pam_mkhomedir.so skel=/etc/skel/ umask=0077 to my /etc/pam.d/system-auth And it does nothing.

Hi ! We are curently deploying an 8 nodes cluster where we have a RHEL 6 license at great costs (~14 k$/y). It will be our new production environment for mission-critical services.
