CentOS 5 :: CentOS5 With Clustered Lvm2 : Not Booting Anymore (VolGroup00 Not Activated)?
Sep 13, 2010
I "inherited" a cluster of 2 systems with XenCluster, based on CentOS 5.5. About five weeks ago I ran the (long overdue) yum update, which crashed in the middle of updating on both nodes, so I had to reinstall all those packages by hand and had to re-enable their startup. So both systems are already in the not-ideal state.
One system rebooted itself during my absence and now won't boot anymore. It seems to boil down to clustered lvm not being activated in the initrd and therefore no VolGroup00 available, which contains the root. The other volume group has good reasons to be clustered but the root does not need to be. But I can't fix it from a rescue CD, every time the error comes up that the volume group is clustered.The exact error display at boot is at
http://people.cs.uu.nl/koos/screen-20100913140414.png
what do I do to either fix the startup to ignore VolGroup00 being clustered OR change the status of VolGroup00 to non-clustered?I notice the other system has this too so my best guess is that I'll have the same problem in a bigger way when this system reboots too. Hoping for no power failures...Relevant versions of stuff:
centos 5.5
kernel 2.6.18-194.11.1.el5xen
mkinitrd-5.1.19.6-61.el5_5.2
lvm2-2.02.56-8.el5_5.6
lvm2-cluster-2.02.56-7.el5_5.4
(from the still running system)

I am using LVM2 Clustering to mirror logical volumes between 2 different storage arrays ( iscsi target hosts). Everything is up and running fine, but I would like to be able to monitor the status of the mirror(s), and "re-sync" them if necessary.
I have attempted the locate the information from Google. From what I have read, lvdisplay -v should tell me whether the mirrors are in sync, but it either is not, or I am simply miss reading it. I have come also across information stating lvchange -m [ 0 | # ] should be used to add or remove mirror copies. Is the is correct / only way to "resync" a mirror, in the event that I can determine the mirror is actually out sync?
For those who are familiar with Symantec's VERITAS volume manager, I am looking get the equivalent information related to plexes from vxprint, the equivalent function from /etc/vx/bin/vxreattach -br, and the progress information from vxtask list. I hope the information is currently "search challenged", or I am simply not fully comprehending what I have found.

What I am trying to to is set up a cluster as follows:
- There are four nodes
- Nodes three and four have large amounts of storage that will be used for storing user data.
- Nodes one and two will be running a couple of network services.
I'd like have nodes one and two to have a clustered filesystem just between them to store data for the services run only by them.is it possible to share one filesystem between two nodes and another filesystem between two other nodes? The cluster seems to try to make the storage changes across all nodes. They will not be able to spend the extra money to get the same storage in all four nodes. Here is what I have done. I am using CentOS 5.5. After installing CentOS, I did this:
On all nodes:
Code:
[root@node1 ~]# yum groupinstall "Clustering"
[root@node1 ~]# yum groupinstall "Cluster Storage"
[root@node1 ~]# chkconfig ricci on
[code].....
...which I think makes sense because the cluster was supposed to create the PV and the volume group, but did not. I don't even think it tries. The first time it tries to do anything to another node is when I create a logical volume.

Haven't been able to boot here lately. Installed Lucid Lynx via Wubi. Tried reinstalling grub, with no avail. Tried using Lilo and now it says I have no activated partitions. I can only boot if I use a LiveCD or Super Grub Disk to find my Windows XP Loader. Here is my results.txt from the boot info script:

This is my development virtual machine, I had Centos 5.3 on it and a lot of stuff I really can't afford to lose.
First off I'd like to say if there is any method anyone knows of recovering information off a VMWare disk, I'd love to trash it. I've already tried the drive mapping in VMWare workstation but only the boot partition comes up and I need /home and /etc.
I was screwing around with the LVM size of the disk and totally screwed it up. I can see the two partitions on /dev/sda, /dev/sda1 as the small partition and /dev/sda2 as my large data partition (the one I need access to).
If anyone could guide me into getting my data off or rebuilding my LVM to get it booted again that'd be amazing.

I'm trying just a generic yum update to bring the machine up to date, I'm running into problems with two packages and their dependencies, kpartx and lvm2
I've removed any additional repositories, and performed a yum clean all
I think my problem comes down to device-mapper, it's asking for 1.02.32-1 to install lvm2 however if I run a yum list device-mapper it only shows 1.02.24-1.el5 as installed, and it is not marked for update. I've tried downloading the rpm directly, If i try to install the rpm with yum I'm told that there is nothing to do, if I try to install directly I run into problems with conflicts with the already installed package.
The kpartx seems dependent on device-mapper-multipath
I'm getting this problem on 2 machines.

My computer had been running just fine a couple of days in a row. I had a problem and decided to reboot. But all of a sudden Ubuntu does not boot anymore!
The error shown is:
Target filesystem doesn't have /sbin/init. No init found Try passing init=bootarg
Under it it shows
Busybox v13.3
(initramfs) [etc])
[then a couple of rows mentioning removable disks which is my card reader. And finally just a blinking _ sign.

I recently installed Fedora as dual boot with XP on my netbook, but then decided to uninstall it again. I probably did it in the wrong way because everything is messed up. I installed Fedora in a separate partition, so I just deleted that partition. Now when I rebooted my netbook, it starts GRUB.
I get some sort of command prompt like cmd.
grub> {here I can type commands}
I tried several stuff to get everything normal again. First I made a bootable USB which starts the XP Recovery console. Then I used these commands :
Code:
fixboot
fixmbr
I reboot, and there it is again ... the GRUB. How can I get Windows XP working again? I didn't touch the C: boot partition, so the XP installation should still be intact.

What is the best way of specifying the names of ethernet devices in CentOS5.5 or later? There seems to be at least two ways of doing this: Would the 60_net.rule file override a 010_netinterfaces.rules file because it gets executed later, or would the 010_ net interfaces. rule file set up the info in /sys which would then be used by 60_net.rule?

I have Linux Mint and Windows 7 installed on my laptop, and recently tried tinkering with EasyBCD, to use the Windows multi-boot loader instead of grub. Well, that didn't work out too well, because I ended up with the Windows boot loader with two options, Windows 7 and Linux Mint, however the Linux Mint entry just redirected me to grub, which wasn't what I intended.
I tried to put things the way they were, with grub as the only boot loader, and figured I'd do so by setting EasyBCD to skip the multi boot screen and going straight to the Linux Mint entry, which corresponds to grub.Well, now when I boot, I get the grub screen, but if I select the Windows 7 entry, it just redirects me back to grub, so I can't access Windows 7 right now. What can I do to fix this? Can I edit the Windows boot loader from within Linux?

I am trying to see if a can get a centos 5.5 server setup as an smtp store and forward spamfilter by following the Centos Wiki and the freespamfilter.org guide by Mr88Talent at [url], which relates to another linux distro.
The spamfilter is essentially working! however, i have one issue with DCC.
test problem:
I'm not sure if anyone else would be interested in a Centos version of Mr88Talent's tutorial, but a very rough and completely untested first effort is available at the following url: [url]
Any opinions on this setup or just a total slating of everything i have done wrong would be welcome as i don't want to waste time trying to use a setup that is just not going to be practical or reliable to maintain / keep operational.
I have read that yum update can break this type of system - which concerns me.
The intended use of the spamfilter is for a small business (only about twenty e-mail accounts). However, they still need to reliably receive e-mails (hopefully with less spam though).

I made a mistake with lvm2 on centos 5.2.
I used parted to create a partition inside the logical volume, and then merrily used that partition, which appeared as /dev/pv-whatever/lv-whateverp1
Of course I created the FS as ext3.
So, after a reboot, I can't access anything in that logical volume with standard tools, as /dev/pv-whatever now only has the lv-whatever special file inside.
I can look inside the LV with parted fine, but parted can't copy ext3 filesystems.
Is there any way to get the data out of a partition created INSIDE a logical volume if that filesystem is ext3?

Trying to do a yum update to get everything to latest, towards the end it says this:
[Code]...
how to get around this? I tried yum clean all, then yum update, again but it did the same. I had other deps missing on other servers but yum clean all fixed them -- can't find anyone else who's had this specific issue either, nor an rpm called 'device-mapper-event' or the other things that are missing - am kinda stuck!

I have read that when using xfs with lvm2, prior to kernel 2.6.29 write barriers are by deffault disabled.As i want to migrate /home to xfs (and create a external partition to hold some data in xfs too) i was thinking in compile a custom kernel 2.6.30 or higher from [URL].I have read the wiki, all the warnings , and that for compile a kernel.org kernel you should use the Linux Kernel in a Nutshel guide/book. But i don't really know if would worth do that only to have write barrier support , more when in one month i will buy a ups to be sure i can shutdown the pc well if the power goes out.Should i enable write barriers on xfs with lvm2 ,although going to have a ups ?

I have a new system using an Intel DG451D main board. I have been trying to get a RAID 1 mirror set working as the main drive in this system and for some reason, my SATA drives - three of them all new have had their SMART data changed to show the drives as failing and in need of replacement. Eventually the drive reports failure to the degree that the BIOS no longer recognises it. When loading the Centos os I was getting differing results because of this issue. I am not sure if this is a hardware issue even - I know that the drives were all very much OK and brand new - no good now! Just putting a feeler out to see if anyone has had a similar issue or to see if anyone knows of any possible known causes for this?
Failing any explanation, can anyone suggest a good desktop style Main Board that supports RAID well for Centos 5.4? I plan to sue this as a small server system so graphics etc are not important here.

I'm looking for a way to have two hosts talk to the same volume without the need for backend host communication ie. clustered file systems? Does anyone know of a clustered file system that will allow this? The basic idea I have in my head would be turn off caching and utilize stubs or pointers to let each host know when to reread new data? The hosts will not be writing to the same files or directories at the same time. They will also be targetting certain information in certain locations on the volume.
I'm trying to join two enclaves to pass data without networking. One host will drop a file and write a stub saying the file is there. The second host will then pick up the file analyze it and then drop a report so that the first host can then pick the report up.

I Made a fresh Installation of Fedora 13. It shows VolGroup00 and File System in the Computer on desktop.
The size of the hardisk is 160gb. The file system shows some 4gb. I'm not able to open the Volgroup00. On double clicking it it shoes the error "Unable to mount location"
on entering fdisk -l,
It says the partiton one /dev/sda1 did not end on cylinder boundary.
The partition /dev/sda1 ends on Cylinder 63 and the emaing LVM partition also starts on Cylinder 63.
I tried reinstallling after dropping both the partiotions 4 times, but this is always the case.
