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

Re: [CentOS] Problem getting eth0 up
by Lisandro Grullon 17 Aug '11

17 Aug '11

Is you network card even loaded when you type "ifconfig -a" in the $hell? Give us more details as to what you are doing to get the DHCP address. >>> Alfred von Campe 08/16/11 4:57 PM >>> I'm just starting to test CentOS 6 in our environment, and as a first step did a basic install from DVD (Desktop target, all defaults). Next I will try to automate the installations as I did for CentOS 5 using the anakonda-ks.cfg file generated by the manual install. However, I can't wrap my brain around the new NetworkManager to get it to configure the eth0 interface to obtain an IP address from our DHCP server. I've seen the FAQ on the wiki and the interface is up, but it doesn't get an IP address. I've done the installation from DVD multiple times now, each time with the same result. What am i missing?

OT?
by Dave Stevens 16 Aug '11

16 Aug '11

I have a CentOS server with postfix running. A pop user's account was compromised and a lot of spam started being sent. My upstream ISP's mail program started refusing to talk to me because of the very high rate of mail, error 451. I disabled the compromised account. I then changed the postfix settings to deliver mail directly and flushed the mail queue. This resulted in spam being sent out. There were about 20K mails in the queue. I don't know how I might have handled this better, I would have preferred to not send the spam, but the volume was large and the labour of sorting out spam from legit email was prohibitive. Advice? A better list for this issue perhaps? Dave -- "It is no measure of health to be well adjusted to a profoundly sick society." Krishnamurti
