Building for older versions
by Michael Eager 23 Nov '15

23 Nov '15

Hi -- I'm trying to build an application on CentOS 7 which can run on older versions of CentOS. I'm running into problems with versioning of memcpy in Glibc. Executables built on CentOS 7 require memcpy from glibc-2.14, which causes the program not to load on systems with older versions of glibc. My online search suggests to add an asm() with a .symver option to select memcpy from glibc-2.2.5 in each of the source files which reference memcpy(). This isn't practical with a program with tens of thousands of source files. Does anyone have a reasonable solution? -- Michael Eager eager(a)eagercon.com 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077

After reboot of web-server accessing website shows "Forbidden", restarting httpd all is fine
by Jobst Schmalenbach 23 Nov '15

23 Nov '15

Hi. I am stuck with this one and I do not know where and how to search for this problem nor do I know how to fix it. When I reboot one of our servers (CentOS 6.7, selinux target, yum fully updated) the http server loads fine (no erros) but when accessing one of the server's websites it displays "Forbidden", restarting the httpd server (command line) will give full access and all is fine. What troubles me that a simple restart of the daemon fixes everything but it does not come up on reboot.

Putting selinux into permissive mode starts the server right from boot. Looking at all the logs I cannot see anything. Any ideas?

[Slightly OT] - Looking for shadow-utils 4.2 SIG or SCL
by Anthony K 22 Nov '15

22 Nov '15

Hi. I'm looking to run unprivileged containers on CentOS 7 and this apparently requires shadow-utils 4.2 or higher [*0*]. CentOS 7 currently has: # rpm -q shadow-utils shadow-utils-4.1.5.1-18.el7.x86_64 Is there a SIG or SCL that provides an updated package to facilitate my venture or am I left with the only choice of manually managing shadow-utils if I go the route of rpmbuild?

CPU Limit in Centos
by Edward Ned Harvey (centos) 21 Nov '15

21 Nov '15

A few years ago, I vaguely recall some issue with RHEL needing a special license or something like that, if you had more than a certain amount of CPU's or a certain amount of RAM. Does Centos work fine for 2 CPU's, 16 cores, 32 threads, and 256 G of ram? Centos6 specifically.

I have CentOS 6 box with 4 CPUs, 64 CPU cores and 512 GB of RAM... for about two years. Runs great.

EL7: Detecting FS errors on XFS while mounted
by Benjamin Smith 20 Nov '15

20 Nov '15

Is there a way of checking an XFS filesystem for clean/dirty status while mounted? One of the checks we've long performed is an FS-level error check. This is *not a full-on fsck*, this is "asking the file system if it noted any problems". This is done while the file system is mounted and "hot". For example, here's how we'd check an ext* partition: # debugfs -R "show_super_stats -h" /dev/md127 | grep -i "Filesystem state" We'd look for "Filesystem state: clean" (or something else if not clean). ZFS also allows for a "hot & mounted" check for dirty file system: # zpool status So far, I've been unsuccessful in finding an equivalent for XFS.
