[CentOS] Centos 5.6 Kernel Panics
Hello, Recently our dell sc1425 server has been locking up with kernel freezes and required a hard reboot on each occasion. I've looked on the centos forums with limited success - each problem seems slightly different (some failure on high load, some not). Our kernel is 2.6.18-274.17.1.el5 and /var/log/messages show the following errors: Apr 3 12:41:25 sp2 kernel: INFO: task mysqld:15345 blocked for more than 120 seconds.

A memory test first and foremost. Check for any corruption on the file system. Chances are rare, but the on disk kernel could be damaged by data corruption. Unfortunately, I don't know of a practical way of testing the buses and possibly even then CPU aside from swapping hardware out. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Hi, I've seen comments about the poor performance of these cards with raid 5 configs. I have an old card with 3 x 500G IDE drives connected in raid 5 and I'm getting around 10mb/s write performance. :-( I'm seeing high iowait figures at times and associated very high cpu load average figures, probably because, under load, everything is stacked up waiting for the disks to actually do something. A non-raid sata disk in the same machine manages 70mb/s Does anyone know what the performance is like if I used the 3ware just as an IDE controller? I could then switch to software raid5? Since you have IDE drives, you obviously have 3ware 7506 card, which is very old. I'm not sure when it was released but that might have been before Y2k. Anyway, at least 10 years ago. It's not fair to talk about 3ware card performance without specifying the card when you mean that old card. Their 9650/9750/9690 of today are more than one generation newer, there has been 8xxx and 9000/9500 series that also are obsolete now. If yoy use 3 drives and configure 7506 as a transparent controller for each of them, and set up a software raid, then all the drives are behind a single pci slot, which also could be a bottleneck if you don't have a 64-bit pci slot. That said, I seriously recommend jumping to something more up-to-date technology. But don't expect that newer 3ware cards were even close to that slow. -- TiN ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Centos 5.6 : Apache bug fix = PHP Exec no longer works
A few days ago I upgraded from the Centos 5 CR repository software including Apache. The Apache on my development server is: Apache/2.2.3 Aug 31 2011 20:18:21 httpd.x86_64 0:2.2.3-53.el5.centos.1 A previously working PHP Exec(...) command on a web page no longer works. After spending 7+ hours Googling, checking file and directory permissions, whether SELinux is on or off and doing numerous tests my once very nice routine will not work because the Shell processing by Apache seems to have altered. The consistent error message always includes: No such file or directory or command not found I have downgraded to httpd.x86_64 0:2.2.3-45.el5.centos.1 and restarted httpd but the problem persists. It appears to me, the PHP EXEC command is being executed in a 'black hole' with no access to the directory structure and that is why the weird error message occur. Helpful comments appreciated.

CentOS' 5.3 doesn't Provide: php and has some other issues the last time I looked. Thanks John. The IUS repository looks really good (or reliable). It seems that they have also used the same type of naming convention used by Redhat for php53 with the addition of i or whatever. This is pretty nice for adding and removing packages. Unfortunately, I'm thinking that this will cause the same dependency problem as things like php-common won't be found. Yes, I know I 'can' just go do an install of something like SquirrelMail, something we immediately would need, but that would potentially just be the beginning of issues on a shared hosting system. It sounds like I should just sit back and wait for 6 if I want to stay on upstream (and select repos) for package updates. That has been my hard headed decision for many years and in those many years, has proven to save a lot of future grief and eliminated in some cases some additional downtime during compiles. Looks like if my need for PHP53 is absolute, I'll just move that client to the one 'custom' system and they'll just have to understand that there might be a bit more downtime, then move them onto a 6 box once deployed. And yes, PHP has been the one thing that has repeatedly been the dawg with using Redhat. 6 was way late out from upstream and then the promised option in 5 appears to be at least a bit of a smoking gun. -- John Hinton 877-777-1407 ext 502 http://www.ew3d.com Comprehensive Online Solutions ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] CentOS 5.6 - Samba server + Windows error 233
Hi! I have upgraded my servers yesterday to CentOS 5.6 via yum update. Everything went smoothly except that i have client workstations not part of the domain that are not able to access the samba server anymore. The samba server is part of the domain. We recently added Windows 2008 R2 DC. Everything was working smoothly until the CentOS update. I had a Win7 Workstation that i had success connecting when using the net use command: net use g: \\sambaserver\share /user:domain\username The mapping worked right away and didn't even asked for the password. Normally, before the CentOS upgrade, i'd put \\sambaserver in the UNC line of the Windows Explorer and i'd get a box asking for credentials. Entering domain\username as user and giving the password in the password line was working. Not anymore. I have another XP workstation on another subnet (router wide open) and the mapping with the command line as specified above doesn't even work. For this subnet, i have to use the IP address because the workstations on it use a DNS which isn't aware or active directory (and cannot change this). samba-3.0.33-3.29.el5_6.2 samba-common-3.0.33-3.29.el5_6.2 Here is my smb.conf: === [global] workgroup = DOMAINNAME realm = DOMAINNAME.COM server string = Servername File Server socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 security = ADS encrypt passwords = yes passdb backend = tdbsam password server = * preferred master = No local master = No domain master = No cups options = raw hosts allow = 10.0.2., 10.0.3., 127., 10.0.4.40 pam password change = Yes passwd program = /usr/bin/passwd %u passwd chat = *New*Password* %n\n *Re-enter*new*password*%n\n *Password*changed* username map = /etc/samba/smbusers unix password sync = Yes log level = 1 syslog = 0 log file = /var/log/samba/%m max log size = 50 smb ports = 139 name resolve order = bcast hosts time server = Yes printcap name = CUPS show add printer wizard = No add user script = /usr/sbin/useradd -m '%u' delete user script = /usr/sbin/userdel -r '%u' add group script = /usr/sbin/groupadd '%g' delete group script = /usr/sbin/groupdel '%g' add user to group script = /usr/sbin/usermod -G '%g' '%u' add machine script = /usr/sbin/useradd -s /bin/false -d /tmp '%u' shutdown script = /var/lib/samba/scripts/shutdown.sh abort shutdown script = /sbin/shutdown -c # separate domain and username with '\', like DOMAIN\username winbind separator =+ # use uids from 1 to 2 for domain users idmap uid = 1-2 # use gids from 1 to 2 for domain groups idmap gid = 1-2 # allow enumeration of winbind users and groups winbind enum users = yes [homes] comment = Home Directories read only = No browseable = No writable = yes [Videotheque] comment = Fichiers MPEG2 path = /home/Samba/Videotheque read only = No available = Yes public = Yes writable = yes admin users = domainname+user1,domainname+user2,domainname+user3 TIA, Guy Boisvert ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] CentOS 5.6 x86_64 hosting unreachable Virtualbox 4.0.6 bridged guests
Hi, On a box running CentOS 5.6 x86_64 and Virtualbox 4.0.6, I have configured 2 guests (WinXP x86 + CentOS 5.6 x86_64) in bridged mode. The hosting box and the two guests are dhcp enabled. The hosting box get its address normally, but the 2 hosted systems fail to get theirs. The dhcp server log tells : DHCPDISCOVER from 08:00:xx:xx:xx:xx via em0: network xx.xx/16: no free leases.

Please note that: - Kernel and softwares on the hosting CentOS are up-to-date, the box has an Intel Corporation 82567LM-3 Gigabit Network Connection (rev 02) NIC, does not have an Intel VT compliant CPU (Pentium E5700), but VT/AMD-V enabled in bios. - The host is not configured in bridged mode (does not have a br interface configured), Oracle telling that bridged mode on the host is not required to run Virtualbox guests in bridged mode. - The 2 guests work perfectly in NAT mode, but this mode is not an option for me. - The same 2 guests work perfectly in bridged mode on another same hosting box running Fedora 14.

I am running Virtualbox 3.1.2 in bridged mode with WinXP guest OS but use a fixed IP address as its in my home network, hardwired, and I want my DNS to be complete with forward and reverse lookups for my CentOS workstation host as well as my WinXP guest. I only use DHCP for my wireless clients (hard allocate IP and hostname based upon ethernet address) and true guests to my network. The bridged method works fine - no bridge on host just normal ethernet - bridged on Virtualbox. As it works I have not moved up to version 4 as yet - probably will when CentOS 6 gets released and I build a new workstation. There are just a few pesky apps that insist on using windows / IE and have no viable open source alternatives that keep me using a WinXP guest. attachment: rkampen.vcf___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

List, I was not able to resolve my issue with the time on this machine. I went ahead and rolled the update back to 5.5 and disabled the update to 5.6. What I would like to know is if CentOS 6 might be ok when it rolls out, or am I just going to have to keep with 5.5 till EOL? Thanks to all with there help. 1) I hope you are only talking about having rolled back to the last working for you kernel from 5.5, not the whole distribution. 2) If I was in your position and had time, my method would be[1] a) get the srpm for the last known working kernel (2.6.18-194.32 ???) b) get the srpm for the first known not working kernel (2.6.18-238 ???) c) expand each of the above srpms into their own rpm build tree i.e., rpmdev-setuptree;rpm -i kern1; mv rpmbuild rpmbuild.kern1; rpmdev-setuptree;rpm -i kern2; mv rpmbuild rpmbuild.kern2 d) start looking at the differences in the patches applied in kern1 vs. those in kern2, i.e., read/diff the kernel.spec files see if there were any new ones that seemed likely to be causing the problem... RTFS if necessary to make better guesses. Rebuild kernel 2 with patches taken out/modified based on my investigations and test them and see if I guessed right. If no luck, think about opening an TUV bug with lots of the info you have sent here, they may be interested even if you don't have a subscription.

The time goes downhill. Uphill actually To answer the previous question I do have the HW clock set to utc, Everything is stock from initial install of the package. Did you check dmesg which timer is being used (I think it can also be seen somewhere in /proc but I don't remember). If it's hpet, you could try to disable it. That was for i686: 'hpet=disable' and for x86_64: 'nohpet', don't know how it is with current kernels. Simon Forgive me if I've missed a later post but it looked like this thread was stagnant... You may have something here Simon. I was thinking about your suggestion that it could be a timer issue. I'm wondering if the default clocksource or some related timer kernel parameter has been changed between 2.6.18-194.17.4.el5 (5.5) and 2.6.18-238.5.1.el5 (5.6). Timer related issues could very well account for this large, inconsistent NTP drift as well as Florin Andrei's bizarre tar, scp, and NTP issues in the [CentOS] bizarre system slowness thread. System interrupts are based on the clocksource chosen by (or configured in) the kernel. Any service or facility that uses these interrupts could be experiencing problems. Can anyone on the list confirm whether or not timer related kernel parameters have changed in 5.6? I don't have source handy and I'm going out the door in minutes. Reading up on kernel timer options, I came across these articles. # Discusses mis-detected timer frequency 9.2.4.2.7. Kernel 2.6 Mis-Detecting CPU TSC Frequency http://support.ntp.org/bin/view/Support/KnownOsIssues#Section_9.2.4.2.7. # Describes ntpd instability from some time sources # Includes data and graphs from detailed study http://www.ep.ph.bham.ac.uk/general/support/adjtimex.html I checked clock sources on a few systems under my control to see what came up. None are experiencing this problem. The CentOS and FC12 machines are isolated from the Internet while the FC14 laptop connects. My sample CentOS 5.5 5.6 systems are different hardware platforms. The 5.6 box doesn't have the hpet timer available so it may just not be susceptible to this problem. I'll be updating the 5.5 sample to 5.6 tomorrow which does have hpet available so I should know something more then. # Used these to get available and current clocksource: cat /sys/devices/system/clocksource/clocksource0/available_clocksource cat /sys/devices/system/clocksource/clocksource0/current_clocksource # CentOS 5.5: Available: acpi_pm jiffies hpet tsc pit Current: tsc # CentOS 5.6: Available: acpi_pm jiffies tsc pit Current: tsc # Fedora 12: Available: tsc hpet acpi_pm Current: tsc # Fedora 14: Using hpet Available: hpet acpi_pm Current: hpet ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It also occured to me to ask if this was running in a VM, but it sounded
like it was running on actual hardware.I once had a vmware VM in
which I had similar misbehavior of the clock. Eventually I discovered
that the following simple program when run inside the VM would return
immediately instead of delaying for 10 seconds as it should.
#include stdio.h
/* #include sys/select.h */
#include sys/time.h
#include sys/types.h
#include unistd.h
int main() {
fd_set set;
struct timeval timeout;
int filedes = STDIN_FILENO;
FD_ZERO (set);
FD_SET (filedes, set);
timeout.tv_sec = 10;
timeout.tv_usec = 0;
select(FD_SETSIZE, set, NULL, NULL, timeout);
}
I then found out that the ISP had set the host OS for my VM to Ubuntu
when I was running CentOS 5 in the VM. The cause was that VMware
assumed a tickless kernel for Ubuntu, but not for CentOS 5 and there
were optimizations in the VM emulation that counted on VMware knowing
what timekeeping options where set in the kernel.

I have always used ntp to sync this machine and then the rest of the machines in the network would sync from it. Since the update I cannot keep the right time on the machine. This is with / without ntp. I have attempted various scenario's with no luck. I am now trying the old kernel now as I type this out. If anyone else has any links or ideas that I should check out It would be greatly appreciated. Just a quick note about my setup. I do not use any gui. As mentioned I have not had any issues with this machine and it's time until I upgrade. AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ 3gb of ram. TIA. Brian. Just to follow up, I had switched to the old kernel before the 5.6 upgrade, and at this time my clock is working flawlessly. kernel v. 2.6.18-194.32.1.el5 Works as it should... kernel v. 2.6.18-238.5.1.el5 I cannot get my clock accurate. If there is anything I can do to help solve this IE: information or test. please let me know.At this point I will just make the old kernel default boot until there is a kernel update where which I will try again.

Johnny, Yes, As long as I run the older 5.5 kernel my time is perfect. All clients can get from this machine with no issues. As soon as I run new kernel, or Plus kernel for that matter.

Did you check dmesg which timer is being used (I think it can also be seen somewhere in /proc but I don't remember). If it's hpet, you could try to disable it. That was for i686: 'hpet=disable' and for x86_64: 'nohpet', don't know how it is with current kernels. Simon ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] CentOS 5.6 and php53 packages
Hello fellow CentOS users, until now I was using CentOS 5.5 with php 5.3 through this file: # grep -v ^# /etc/yum.repos.d/CentOS-Testing.repo [c5-testing] name=CentOS-5 Testing baseurl=http://dev.centos.org/centos/$releasever/testing/$basearch/ enabled=1 gpgcheck=1 gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing includepkgs=php* Today I have updated to CentOS 5.6 by running yum update and only after that (mea culpa!) I've noticed at http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.6 - 6.2. New packages in 5.6 that were not present in 5.5 bind97 hplip3 php53 Do you think it is safe to remove /etc/yum.repos.d/CentOS-Testing.repo and run yum update again or will my Drupal 7 site burn and die?

You should be fine. the php53 is now in the main distro. The testing packages were put into the Testing repo so that people could do just that - test and see how their apps get along, before 5.6 gets released. - KB ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Unless you have an exclude=php* or exclude=php53 in your CentOS-Base.repo, you likely have already upgraded. The php53 rpms in the updates directory are php53-5.3.3-1.el5_6.1.src.rpm wich is newer than the version that is in testing (php53-5.3.3-1.el5.src.rpm) If you do this, you can see which version is installed: rpm -qa php53\* You will likely see packages with el5_6.1 in the name. signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
