[CentOS] 6.3 installer keeps cycling in a 10 second countdown to boot
Hi. I've been running CentOS 5 for ages. (Thanks!) I went to install 6.3 - I downloaded the 64-bit DVD 1 image, and put it on a USB drive. Booted into a screen that said boot will start in 10.. 9... 8.. 7.. 6.. 5.. 4.. 3.. 2.. 1.. 10.. and so on, infinite loop, the boot never starts. I tried booting in text mode, but it doesn't boot, just goes back to the menu. Is there some way to find out why the centos installer refuses to start? I used to have CentOS 5 on this system. I'd expect 6 to work. Thanks, Aleksey ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Installing yesterday's CentOS (or how to install the patch/package set from 3 weeks ago)
Hello, Let's say your operating policy is "no patch updates without testing first in the test environment". Let's say it takes you 3 weeks to test. Over the course of the 3 weeks, the repo changes (new packages added, old removed). Is there a way to "freeze" a set of packages so that when I run "yum update" on a Prod server it'll get the same package and patch set as the Test server did 3 weeks ago? It's been suggested to maintain a local mirror, and take rsync snapshots of it daily, so then you can point the end node to a particular repository. What other solutions are there?

[CentOS] How to set selinux policy "allow httpd_t unconfined_t:shm { unix_read unix_write }; " using an seboolean? (How to get a new seboolean?)
Hi. I'm trying to get OTRS running on CentOS 5.5 with SELinux enabled, and audit.log / audit2allow tell me I need to add the local policy: #= httpd_t == allow httpd_t unconfined_t:shm { unix_read unix_write }; which I think will allow the httpd access to read and write from shared memory? Is that right? What are the risks involved in opening this? I notice it is denied by the default policy.

[CentOS] pdflush kernel thread pops up every 10 seconds or so and video decoding grinds to a halt for 1/2 a second
Hi. A friend of mine was doing real-time video decoding on Fedora Core 13 and he had a performance glitch (1/2 a second freeze) every 5-10 seconds. "top" showed flush-253:0 process at the moment of the freeze. Major device number 253 corresponds to device-mapper. I advised my friend to re-install his FC13 without LVM, to see if the glitch is related to LVM. After re-installing FC13 without LVM, he is seeing the glitch every 10 seconds, and it shows flush-8:16 where before it said flush-253:0. 8 is scsi disk driver. So it's not an LVM thing... maybe a kernel thing? I suggested he try Fedora 14 beta, as it has a newer kernel. Maybe this kernel thing is fixed in the newer kernel. He also tried CentOS 5.5, and saw a "pdflush" process popping up with the same frequency, and resulting in a similar glitch. Any other suggestions?

Apache HTTP Server: httpd-2.2.3-43.el5.centos.3 mod_php: php-5.1.6-27.el5 PHP PostgreSQL interface is provided by: php-pgsql-5.1.6-27.el5, which uses postgresql-libs-8.1.21-1.el5_5.1 which provides /usr/lib64/libpq.so.4 which we've observed has a memory leak (and this memory leak is NOT present in libpq.so.5.2) I am trying to figure out how to get our httpd/mod_php/php-pgsql to use libpq.so.5.2 instead of libpq.so.4, and I thought I'd start by asking the php-pgsql maintainer, so this problem is fixed for everybody, not just for me.

Re: [CentOS] system "stuck" with 2.6.18-128 kernel. how to move to 2.6.18-194.17?
Thank you very much for your replies and suggestions! Turns out I have a broken RAID. I checked the failed out drive by mounting read-only the /boot partition, and it is configured to boot the older kernel version (the one the system actually boots). Like Phil said, the OS is seeing one thing, and GRUB another. Questions: 1. How do I fix the array? (How do I put the failed out drive back in? (I hope it is a small failure that the software RAID can recover from, like a few bad blocks or something. Otherwise I am willing to replace the drive.) # mdadm /dev/md0 --add /dev/sda1 mdadm: Cannot open /dev/sda1: Device or resource busy # Maybe it's busy because the system really booted off it? Maybe I can edit grub.conf to change hd(0,0) to hd (1,0) and reboot. Where do I do that, in /dev/sda1 or /dev/sdb1? I guess I could do it in both places. What do you think? Note: I was able to add /dev/sda3 to /dev/md1, and it is resync'ing the array now. # mdadm /dev/md1 --add /dev/sda3 mdadm: re-added /dev/sda3 # 2. Is there a different configuration I should adopt, so that OS and GRUB agree on what device to boot from? Or is this the price I pay for using software RAID rather than HW RAID? Data: The /etc/grub.conf sym link is set up correctly: lrwxrwxrwx 1 root root 22 Mar 17 2009 /etc/grub.conf -> ../boot/grub/grub.conf My /boot filesystem lives on a RAID 1 array: /dev/md0 on /boot type ext3 (rw) /proc/mdstat shows only /dev/sdb is still in the RAID 1 mirror: Personalities : [raid1] md0 : active raid1 sdb1[1] 104320 blocks [2/1] [_U] md1 : active raid1 sdb3[1] 275964480 blocks [2/1] [_U] unused devices: For some reason, it does not show "F" for disk failure.

Hi. Our CentOS 5.4 server just rebooted sponteneously while doing heavy I/O.

Re: [CentOS] How can binaries be different when package versions are identical? (mkfs.ext3 on CentOS 5.4)
I read up on "prelink" as suggested; and used "ldd /sbin/mkfs.ext3" to see what the dependencies (libraries) are. There are 13 dependencies; file size is the same between servers but md5sum's are different! Most of these libraries have other libraries they call; I finally drilled down to ld-2.5.so which is statically built. Same thing: same file size, same datestamp, same package version; but the binary is actually different; yet rpm -V does not complain. Why? (Both systems are running CentOS 5.4; one was deployed in December 2009, the other in April 2010.)

[CentOS] How can binaries be different when package versions are identical? (mkfs.ext3 on CentOS 5.4)
Situation: two similar servers, both with CentOS 5.4 64-bit. Making an ext3 filesystem on one takes seconds, on the other minutes. Partition SizeServer 1 Server 2 1 GB 0.7 sec 0.3 sec 4 GB 2.5 sec 1.2 sec 40 GB15 sec13 min WTF e2fsprogs RPM is e2fsprogs-1.39-23.el5 on both systems mkfs --version reports "util-linux 2.13-pre7" on both systems mkfs -V reports the same on both systems (mke2fs 1.3 (29-May-2006) Using EXT2FS Library version 1.39) file size on mkfs and mkfs.ext3 binaries is identical However, checksum on these binaries differs across servers, and "cmp" reports files are different I took "mkfs" and "mkfs.ext3" from server 1, put them on server 2, and got an improvement: 40 GB15 sec3 min Just out of curiousity, I ran "rpm -V e2fsprogs" to see if rpm would pick up the difference and sure enough, it complained mkfs.ext3 changed. Both of these servers have CentOS 5.4; Server 1 was installed in Dec 2009, Server 2 in April 2010. I'd like to: (a) account for the difference in the binaries, and (b) see if something else is different that I can make the same to get the mkfs.ext3 time down to 15 sec on both systems.

Re: [CentOS] Pause time
2010/4/19 cahit Eyigünlü : > i want to pause my cent os time and date in a spesific date :D is it > possible ? You can set your clock back a minute every minute from cron using the "date" command. Try: date -s "now - 1 minute" If that's not good enough, you can write a loop that resets your clock back a second every second, again using the "date" command. while true do date -s "now - 1 second" sleep 1 done That should make time appear to stand still at the HH:MM:SS level. Another possible method is to pause time itself. However your computer won't work any more, and will remain frozen without any changes.

I don't know SE Linux and right now my objective is to get BackupPC up and running. I've turned SE Linux off for now, but that's temporary until I get a more targeted fix.

Re: [CentOS] how to install BackupPC on CentOS 5.2 -- use Testing repository
What's a protect base? I added the Test repository to my yum.conf and then I was able to just yum it in. I bet you already had the Test repository in your yum config, dnk. Thanks for your reply! Aleksey Here is what I added to /etc/yum.conf: [c5-testing] name=CentOS-5 Testing baseurl=http://dev.centos.org/centos/5/testing/x86_64 enabled=1 On 7/31/08, dnk <[EMAIL PROTECTED]> wrote: > Do you have any sort of protect base installed? > > Priorities, etc? > > I could just yum it in when i did it. > > d > > > > > > On 31-Jul-08, at 3:40 PM, Aleksey Tsalolikhin wrote: > > > > > Hi.

[CentOS] Re: how to install BackupPC on CentOS 5.2 -- how do I use Test repository?
Ok, downloading the BackupPC RPM directly did not work to myriad dependencies and sub-dependencies. How do I add the Test repository to my yum config, please?

[CentOS] how to install BackupPC on CentOS 5.2 -- use Testing repository
Hi. I just installed CentOS for the first time, to make a BackupPC server. However, when I try to install BackupPC using yum, I get the error: No package backuppc available. I searched the Testing, Extras and CentOS Plus repositories, and found a BackupPC package only in Testing, at http://dev.centos.org/centos/5/testing/x86_64/RPMS/backuppc-3.1.0-1.el5.centos.x86_64.rpm which I downloaded directly. Just posting this in case somebody else has a similar issue. Best, Aleksey ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
