Backup of large filesystems >500GB
by Mike Watson 28 May '13

28 May '13

I've a small system that I use to support a number of churches. I provide web and email for them. My current server is running CentOS 6.3 with paired 1TB drives in a RAID1 configuration. It works well. One filesystem is very large, >500GB, and contains numerous large files: SQL, docs, church libraries in ebook and digital form, plus stored videos of church services. My problem is that I've found no means of backing up that file system. Dump and tar both error out as exceeding the maximum size. Neither will backup just the video directory (the largest) even with compression. Backup will be to an external (USB) removable HD. Can any suggest a prog or a method to back up this filesystem? mw -- -- "Lose not thy airspeed, lest the ground rises up and smites thee." -- William Kershner http://crucis-court.com http://www.crucis.net/1632search

Run multiple instance of apache
by HAJJ CHEHADE, Ahmad 28 May '13

28 May '13

Hello everybody, I am trying to run 2 instances of apache on centos since 2 weeks with no lucks :S, exactly on the same IP address but different port. I've set up two configuration as follow: /etc/httpd and /etc/httpd2, and I duplicated the httpd service, so now I have 2 httpd service each one run an httpd conf. Now when I am trying to restart the first httpd service, it give the following httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName but the status is OK. And when I try to restart the httpd2 service, it give the same error with a failed status. Some internet research told that I have to put a serverName in httpd.conf (server name was commented) so I change it with the hostname of my VM. Now when I try to restart httpd2 the error message disappear, but his status is always failed. N.B. My first httpd.conf don't have a serverName. My /etc/hosts contain only: 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 Any help will be appreciated.

Dell R320 server
by Jerry Geis 26 May '13

26 May '13

Is there a way on Dell R320 (two power supplies and hardware RAID-1) on centos to get a message that a power supply is failing or that one of the hardware RAID disks is failing? Sure there is the front panel - but no-one is there ... Is that reported to linux/centos some way? This is my first R320. Thanks, Jerry

Centos 6.4: Possible bug in system-config-network-cmd
by Glenn Eychaner 25 May '13

25 May '13

I'm having a puzzling problem with system-config-network-cmd in CentOS 6.4. I have a workstation with a number of different grub boot configurations (a spare for a set of workstations, basically), each of which has a parameter MYHOST=<hostname>, and I am using system-config-network-cmd to set the boot configuration during the network process (using a small custom system service that runs just before network startup, reads the configuration name from /proc/cmdline and calls "system-config-network-cmd -p <configname>"). I have properly disabled NetworkManager, and have /etc/sysconfig/networking/devices and .../profiles set up correctly AFAIK (it was all copied from a CentOS 5 machine, and the hand links were maintained properly as needed; such a PITA that they got rid of the very nice GUI for this). This all works great, EXCEPT that if the machine is booted a fixed-IP profile, the the DHCP ifcfg file also winds up in /etc/sysconfig/network-scripts. So, if I have in profiles/dhcp/ifcfg-eth0_dhcp (with a hardlink in devices/, of course): TYPE=Ethernet DEVICE=eth0 HWADDR=<MAC redacted> BOOTPROTO=dhcp ONBOOT=yes USERCTL=no IPV6INIT=no PEERDNS=yes and in profiles/fixed/ifcfg-eth0_fixed GATEWAY=x.y.z.1 TYPE=Ethernet DEVICE=eth0 HWADDR=<MAC redacted> BOOTPROTO=none NETMASK=255.255.255.0 IPADDR=x.y.z.n ONBOOT=yes USERCTL=no IPV6INIT=no PEERDNS=yes If I boot into fixed, I find that ifcfg-eth0_dhcp is also in network-scripts, and it tries to activate this interface, even though this interface is NOT in profiles/fixed in any way! This worked great in CentOS 5, so I think I know what I'm doing here? For now, I am "fixing" the issue by running a find on network-scripts to remove inappropriate files after running systme-config-network-cmd, but that is complete cheese, of course. Is there something missing from ifcfg-eth0_dhcp that is confusing the system-config-network-cmd script? Is there any documentation on this that's helpful? And is there simply a better way to do this that I've missed? Thanks, -G. -- Glenn Eychaner (geychaner(a)lco.cl) Telescope Systems Programmer, Las Campanas Observatory

Libcurl.so.3: wherefore art thou?
by Gilbert Sebenste 25 May '13

25 May '13

I am utterly stumped. I need libcurl.so.3 for CentOS 6.4. I have Googled everything and I have been going all over the Internet looking for a solution. I give up; I need help. The error message I get when I try to run a program is: error while loading shared libraries: libcurl.so.3: cannot open shared object file: No such file or directory I have: Package libcurl-7.19.7-36.el6_4.i686 already installed and latest version Package python-pycurl-7.19.0-8.el6.i686 already installed and latest version Package curl-7.19.7-36.el6_4.i686 already installed and latest version Package libcurl-devel-7.19.7-36.el6_4.i686 already installed and latest version I also have git installed (yes, I know about the EPEL conflict giving me a 5.9 version) and I do have the CentOS 6 version installed)...no dice. Can anyone help me?

CentOS 6 and PHP
by Glenn Eychaner 24 May '13

24 May '13

Still upgrading CentOS 5 to CentOS 6, and have run into the next issue: When I install httpd and php, everything works great, and the default-test "<?php phpinfo(); ?>" works great. The problem is that I have a bunch of old HTML that seems to use "<?" alone (or worse, "<!--?"), which worked in CentOS 5 but fails in CentOS 6. I can change all the HTML, but is there an easier way? Summary of previous issues: system-config-network-cmd leaving behind "ifcfg" files in network-scripts that it shouldn't: I still don't have an answer for this one; I work around it by naming all the scripts "ifcfg-ethX_<profile>" and cleaning any that don't match <profile> after running system-config-network-cmd. I suspect it has to do with either the contents of /etc/udev/rules.d/70-persistant-net.rules or the format of my ifcfg-ethX_* files, but haven't been able to resolve it. Probably will leave it as "workaround works". UUIDs and boot drives: Didn't solve this one either, but again didn't try very hard because the recovery from a failed attempt is a royal pain. I decided that the actual UUIDs weren't important enough to me to matter, since I seldom boot with more than one workstation's drive connected at a time. I will probably go back to labels, since I can change those (apparently) without rendering the system unbootable.
