I am the system administrator. I have a system that was built with a default install which resulted in everything in a single file system except for /boot wrote some scripts to split out: /home, /usr, /var, /opt, and /tmp to separate file systems/logical volumes it looks like it ought to work, There's plenty of space in all the filesystems and I can log via ssh and have write access in my home directory. Logging in via ssh did result in a new .Xauthority file being automatically created, but that did not help. Googleing around I saw a thread where the user was actually out of disk space, but before that was established somebody asked if /home was on a different filesystem from /, but what to do in that case never came up.

[CentOS] Live CD problems
Hi, I'm trying to repair a remote system using the Live CD. I have VPN access to the subnet where it lives. An onsite person is booting from cd, and running a small script I provided to tweak the default firewall rule set to allow incoming ssh, and set a password for the centos user and start sshd so far so good I can remotely access the system. the problem is the live cd environment is very fragile. I need to rebuild the contents of a couple filesystems, so I need to umount them and remount them rw. If I make a mistake in a mount command instead of giving an error message and letting me try again. The system freezes and any other ssh session freezes, ahnd will not accept any more incoming ssh connections. the only way I have found to recover is have the onsite person reboot from cd and rerun the script allowing incoming ssh again.

[CentOS] Using CentOS Live CD to recover trashed RHEL system
Hi, There's a RHEL5 system somewhere across the internet with a trashed root file system. I have VPN access to the subnet where it lives. But the system is not talking to the network. The current plan is having an onsite person boot from a CentOS Live CD, copy a small script to configure networking, set a password for the centos user, start sshd, and tweak the default firewall to allow incoming ssh connections, once I have remote access to the live cd environment I'll create a new lvm logical volume, create a file system, and restore from a level 0 dump taken from a lvm snapshot just before things broke. I'm pretty confident I have all of the above under control. The part I'm not certain about is the grub voodoo to get the system to boot to the lvm with the restored root file system. I'm not certain of the vintage of the restored root file system it was built from an old RHEL5 installation cd and last updated a year or so ago. I have a CentOS 5.5 live cd .iso image staged for the onsite person to burn. Are there differences in the boot process for CentOS/RHEL 5.x versions that I have to worry about. Would it be better to try to get a closer match between the root file system and the live cd vintages. At the moment I'm googling for info on the grub incantations for changing the root file system logical volume. Any comments suggestions would be appreciated.

Just make sure fstab reflects whats actually in place. The seems to be something here that I don't get! I have booted from a cd and am running CentOS, I'm assuming my active root file system is some sort of read/write ram disk overlaid on top of the read only file system from the cd. At the moment the right terminology to express this escapes me. I have the original system disk that is corrupted. It needs at least two partitions since the boot loader does not yet understand lvm. There is a tiny ext2/3 file system that contains /boot which contains the boot loader/grub stuff. I assuming we are talking about legacy grub not grub2. And there is a second partition containing an lvm PV and within that is a LV containing the root file system. I do have a level 0 dump of /boot in addition to the level 0 dump of / I can restore the contents of /boot and / but things will proabably not end up in the same physical sectors. Running grub the right way should update parameter for the boot loader to first tranfer control to the right place in /boot which then accesses the right filesytem in the right PV/LV You seem to be saying that all I need to to do is tweak /etc/fstab in the root file system in the new pvn/lvm. Actually as I try to explain my current understanding things are getting clearer. It seems to me that at least one more step is required. getting a proper chroot jail environment set up so I can run a grub command to update the boot sectors on the RHEL5 system disk to transfer control to the right place in /boot and update /boot so that it can mount the right filesystem on / I'm still hoping to find complete documentation with an example of how to do this. -- Drew Einhorn You can see a lot by just looking. -- Yogi Berra ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Rather than trying to figure out what you have and how to fix it, it may be easier to start over an build a new system from scratch. This isn't Windows. True. But figuring out which packages came from which repo, can be difficult. There was a hotly debated repotag battle that could have mitigated the problem. The epel folks were strongly opposed. The problem becomes really nasty, when package xyz from repo A, is incompatible with package xyz from repo B. You can probably get the 3rd party repos to play nicer with one another by using yum-priorities. This is related to the problem at hand how? The OP was using packages from the standard repos, epel, and a couple other repos I never heard of for a reason that he did not share with us. yum-priorities can be used to control which packages are installed from which libraries. Count the mumber of packages on your system. Do a: rpm -qa | wc If you have subtle problem with compatability between repos. Do you want to go through all those package determine which repo each package can from and determine whether there are compatibility issues with packages from other repos? Or do you want to start over installing only packages from the centos repos that have been tested by the centos developers. Then add third party repos with yum-priorities preventing centos packages from being replaced by non centos packages, but adding needed packages and their prerequisites from 3rd party repos. There are techniques for finer grained management of compatiblity issues among repositories, that I have never needed to learn about. Someday this is going to sneak up and bite me. Yes, probably, but still not related to the problem at hand. epel is careful not to replace package from the standard repos. I have no idea whether the repos other repos (I never heard of them) are as careful. epel is not concerned about their compatability with other 3rd party repos. And there is a lot of lingering animosity. Just mentioning epel in some places is enough to evoke a bitter response. I did not want to get into those issues. Sometimes the problem does get all the way down to very nasty, tangled compatibily issues among repos, and there is a solution, but it's not easy.

WT Direct DisDskCache. Not sure understand the performance benefit/risk trade offs well enough to choose intelligently for the primary. Especially when the application may be making lots of assumptions about what is happening on the lower levels. And may have much more memory available to do its own caching and optimization. Does the controller really know enough about what's going on in the drive to make effective use of the drives cache to speed things up?

[CentOS] LSI Logic MegaRAID 8480 Storage controller
I have LSI Logic MegaRAID 8480 Storage controller I am having trouble reconfigure one of the hardware raid devices It is configured with 4 hardware raid logical volumes on /dev/sda /dev/sdb /dev/sdc /dev/sdd. I am in the middle of rebuilding the system, and at this point I am only using one of the volumes, /dev/sda /dev/sda, /dev/sdb, and /dev/sdd are all 2 drive raid1 mirrors I will be using the hardware raid logical volumes /dev/sdb and /dev/sdd with their current configurations I doubt that the hardware raid device on /dev/hda is causing any problems /dev/sda has two partitiions /dev/sda1 is a 100 MB ext3 partition mounted on /boot /dev/sda2 is a 20 GB lvm logical volume in a 67 GB volume group with an ext3 partition mounted on / the rest of the volume group is empty. I don't like the /dev/sdc is configued. It's configured as a 4 drive raid6. It will be used for database journal, nearly all sequential writes. I would rather use raid10 There are 3 ways to configure the hardware raid. The is something called WebBIOS which is sort of like a web browser that you access from the BIOS. This is ruled out since we will need to maintain the raid configuration with shutting down the operating system, or applications. There is a MegaCLI command line interface that runs under the operating system. Normally I prefer command line tools. But this software is big, and complex. All I have been able to find is a reference manual, that has lots of typos and is not very well organized for me to learn what I need to know. I have not been able to find a tutorial for this software. It will take more time than I have at the moment to figure out this tool. Finally there is the MegaRAID Storage Manager a GUI tool that runs under the OS. I'm running v2.77-00 So the first thing I need to do is delete the unwanted raid6 logical volume. When I try to delete it, it refuses and says: This is an OS drive. The virtual drive cannot be deleted. Any ideas on how to get past this problem with the MegaRAID Storage Manager, or pointers the better documentation, and maybe even a tutorial for the MegaCLI interface. -- Drew Einhorn ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Hi, If I ssh to a CentOS5 box using just the hostname, not the full name, resulting from appending domain name from the search record in resolv.conf it says the ip maps to the correct full name it gets from reverse dns, and claims the full name does not map back to the ip, but it does as verified by both nslookup and dig If I ssh to the full name instead of the short name, the I don't get these complaints.

Wish I could remember where I saw that tutorial. Want to embellish the example and stripe each side of the mirror. Understanding a mirrored pair of stripes, seems easier than understanding a striped pair of mirrors. But this seems like a place where counterintuitive results are not a big surprise. I can do mirroring and striping in lvm, mdadm, or a hardware raid controller. There are lots of configurations to ponder. What about recovery after a hardware raid controller? What are the chances of being able to replace the controller and start up successfully from drives? I know that assuming the failed controller did write bad stuff to the drives while it was crashing and burning. I would not be surprised if the controller firmware revisions had to match.

Let me add that an effort to make sure EPEL is compatible with RPMforge failed as EPEL wants to become the only repository for RHEL and there is no interest to consider current RPMforge users. EPEL refused the repotag, so one cannot easily identify where a package comes from and mixing repositories becomes harder. Since compatibility is a 2 way interaction and EPEL shows no interest, it is certain that mixing EPEL with other repositories may break something. Also EPEL's Fedora legacy makes EPEL closer to Fedora's Extras packages than they are with RPMforge's packages, which can lead to problems with eg. nagios-plugins or clamav packages. I already foresee a lot of frustration caused by bug-reports that make it not clear that packages come from EPEL (much like in the Fedora era where Fedora Extras packages caused problems with RPMforge that were hard to identify or fix). Also, EPEL packages only exist for RHEL4 and RHEL5, resp 340 and 600 projects while RPMforge builds for RHEL2, RHEL3, RHEL4 and RHEL5, about 3400 projects. We however do not provide any PPC packages.

Re: [CentOS] Thank you: Wiki data for adding 3rd party repository, ProtectBase and Priorities
epel exists, but not ready for prime time? I'm assuming that when it is ready it will go here. EPEL isn't a CentOS repo ... as all the other ones you have listed above are. It is your box though, so you can put it where you want. I would have it in the other 3rd party repos section though One thing to remember is you can have 99 priorities ... so you can have one for each repo if there is overlap of packages ... that will keep you always getting packageA from the higher priority repo (say dag over kbs-CentOS-Extras as an example). You can also skip 5 or 10 between repos instead of one, which makes it easy to throw something in the middle between 2 packagesif you need to. I think epel probably goes between 3 and 4, so I think we need the wider for it.

Re: [CentOS] Thank you: Wiki data for adding 3rd party repository, ProtectBase and Priorities
Great minds think alike. I just sent a message suggesting the same thing. Also, I think I've found that if you really want to use the plus repo it needs to be the same priority as base and updates. That could be a problem. Thanks. Well ... actually, having plus lower is a good thing. BUT, it requires you to exclude the packages that exist in Base/Updates if you use the Plus repo. This is A GOOD THING though. You can install anything in plus that is not a duplicate package in base/updates without a problem ... but you can't accidentally install a package that is also in base/updates without specifically excluding it. Hmm. I'm not sure I understand the easiest way to see the correct solution, to these kinds of problemd. It would be nice if there were a way to see what packages are available, but blocked by packages in higher priority repos, or missing dependencies. This reminds me of another related question but forgot to ask. Don't remember exactly which distribution I was running at the time. But I had problems with yum being unable to install certain packages, because issues with complex dependencies were too difficult for it. Someone suggested switching to the smart package manager, which was smart enough to downgrade certain packages to resolve dependency issues. Have not seen signs of similar problems so far with yum on CentOS. Has yum caught up with smart, or are there still some issues here. -- Drew Einhorn ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Great minds think alike. I just sent a message suggesting the same thing. Also, I think I've found that if you really want to use the plus repo it needs to be the same priority as base and updates. That could be a problem.

Information about the epel repository should be added http://fedoraproject.org/wiki/EPEL But since it is an immutable page someone with more privileges than I will have to do it.

Re: [CentOS] Thank you: Wiki data for adding 3rd party repository, ProtectBase and Priorities
Great idea, But to take it one step further, think I'll use 10, 20, 30, ... That way I'll have room to insert new levels where ever I need them.
