Centos Gotcha: YUM Groupinstall
by david 18 Aug '11

18 Aug '11

Folks I have encountered a situation with YUM that isn't what I expected. Let's suppose I want to install a group, call it G. My first question would be -- is the group already installed. Realize all of this is scripted. So, I use yum groupinfo and I see the list of installed groups, and those not yet installed. If group G is in the list of installed groups, one would think that there's no point in issuing a "groupinstall". But, to my surprise, a group can be listed as "installed", only to find that a groupinstall will actually do a lot of installs. So, I had to adapt my script to perform a "groupinfo G", parse the modules, and individually test them to see if they need installation. I do not understand this behavior -- group G is shown as "installed", but it really isn't. David Kurn

SAS storage arrays, C6, and SES lights
by John R Pierce 18 Aug '11

18 Aug '11

So I'm curious how SAS JBOD arrays and linux MDraid as implemented in CentOS6, and SES (SCSI/SAS Enclosure Services) backplane controllers 'get along' and how much configuration is needed to get the warning lights to work properly. scenario: whitebox server with a SAS backplane or two, daisy chained on a SAS HBA (like an LSI Logic 2008), and disks organized as several raid5/6 using linux mdraid. Does this system have to be configured to ensure that the activity and failure lights match the drive bays, or does the SAS/SES spec all sort that out 'plug and play' ? does mdraid properly set those warning lights automatically on a failed raid element? -- john r pierce N 37, W 122 santa cruz ca mid-left coast

RAID5 suddenly broken
by Mathieu Baudier 18 Aug '11

18 Aug '11

Hello, I have a RAID5 array on my CentOS 5.6 x86_64 workstation which "suddenly" failed to work (actually after the system could not resume from a suspend). I had recently issues after moving the workstation to another office, where one of the disks got accidently unplugged. But the RAID was working and it had reconstructed (as far as I can tell) the data. After I replugged the disk, it was working normally over the last two days (enough to get back to a proper state I guess/hoped) This RAID is used as an LVM volume group for all my important data, among them the root of the operating system(s). It based on four partitions on four separate disks (the third partition of each disk, 3 active, one spare) When booting, I get an error message similar to: raid5 failed: No md superblock detected on /dev/md0. and the LVM volume group does not come up. I then booted using the CentOS 5.6 LiveCD and tried to run a few mdadm command (see just below). It seems that there are some data still lying around, but I'm not very experienced with RAID and I thought that I would ask for advice before trying commands which may impact the data such as assemble, etc. Thanks in advance for any help! Mathieu [root@livecd ~]# mdadm --misc -E /dev/md0 mdadm: No md superblock detected on /dev/md0.

OpenLDAP setup and bootstraping in CentOS 6
by Mitch Patenaude 18 Aug '11

18 Aug '11

I'm having trouble getting openldap through its initial setup. I created a /etc/openldap/slap.conf file with a default rootdn and rootpw, and they didn't seem to take effect. After much wailing and gnashing of teeth I found that if there is a config directory at /etc/openldap/slapd.d, it will ignore slapd.conf. I can't figure out how to translate slapd.conf into the (new?) standard of slapd.d because all the examples I can find still use slapd.conf. Am I better off just deleting (or renaming) slapd.d? Does anybody know the proper format for slapd.d entries? Thanks, -- Mitch Patenaude

5.1.6 php to 5.3, a few questions
by Bob Hoffman 17 Aug '11

17 Aug '11

Alright, looks like I have to do this (centos 5.x install). Some questions.. 1) I imagine I have to uninstall my current version of php...will yum remove want to take a ton of programs with it? Would I have to individually uninstall each package instead? 2) yum down the new version from some repo and then install it. I imagine nothing from the previous setup will be there and I would have to start going through the program and config files to make it work with my system, yes? 3) for those that have done it, how many things broke when you took out the old and added the new? honestly just thinking about getting a new comp, installing centos6, adding some virtuals, moving the sites over to the new one and being done with it. Not comfortable with a version of php that will not be backported like 5.1.6 is with centos team. any problems you encountered, would love to hear about them. thanks
