I want to mirror root hard disk in SUSE LINUX 10.1.I have two 80G hard disks, I searched in google but I did not find any good link to describe this.
Code:
Server1:~ # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda6 16G 1.2G 14G 8% /
udev 1.3G 140K 1.3G 1% /dev

Is root mirroring is supported in RHEL /RHAS operating systems? If so, how to find out whether the root mirroring is enabled or not?

View 3 Replies View RelatedI'm setting up two media servers - one will be primary and the second will be the failover box if the first one dies. My original plan was to use Heartbeat and DRBD to replicate the first to the second, but it turns out DRBD has a limitation of 16TB per volume, and my RAID 6 is 30TB in size. I'm trying to figure out some options.
One is to split the partition into two, so it's under the 16TB limit of DRBD, share both partitions, and then use LVM to join them as a single volume at the OS level. I'm not sure what kind of performance hit that will make on read/write access since now it will need to go through LVM *and* DRBD.
Two is to use something like GlusterFS or XtreemFS. However, I am wary of both of those as the first is a FUSE-based system and isn't really tuned for performance, and XtreemFS is still kind of beta-ish.
Three is good old rsync, but that is a bit too asynchronous in my opinion. I'd like to be able to fail over virtually instantly and not lose any content.This is a production system and performance of the disk systems are paramount, followed by reliability.
I have two web servers. One is active and one is in reserve. I keep the user data (web pages) in sync by running rsync every 10 minutes or so. This copies any changes from the active machine to the reserve machine. But, it's slow, only gets changes every 10 minutes, bogs down the disk, does strange things to files that are changing during the rsync process etc...
I want something that will automatically copy any changes from the active server to the reserve server as they are made. IE I hit 'save' on the active server, it copies the file to the reserve server. Simple!
I've been looking around and I see GFS which is really vastly more complicated than I need. I'm happy with read-only access on the reserve host, so I don't need distributed lock management.
I could theoretically implement this by setting inotify watchers on every file and running an SCP or rsync command when a file gets saved. So, it can't be that hard.
I do not need a true networked file system, as in something I mount over the network. I just want something to keep my disks in sync.
Blue sky thinking at the moment:I have a number of file servers, each at different sites. I would like to be able to make these appear as one, so that files on any server can be accessed from any site, and the user doesn't even see there are multiple servers.Obviously, the internet is slow, especially the upload speeds. So when a file is written the write ought to go to the server on the client's LAN - even if it was previously on another of the servers.However, for robustness, some sort of background mirroring is also wanted. If all the servers were left on and connected, they eventually end up all in sync. But this mirroring needs to be mindful of bandwidth usage; if someone writes a big file to their local server, copying that to the other servers can't interfere with normal internet usage.I think UnionFS or similar might be able to handle the unioning side, but not the mirroring stuff.

Also once I created a New user in my SUSE LINUX SERVER using that A/c I am getting the GUI Desktop but in root i am not able to get it.
It looks like there is some service which is not getting started and my Root desktop get freezed.

View 1 Replies View RelatedI try to encrypt root file system on Opensuse 11.1 and I have found up to two possibilities.
1. [url]
2. [url]
In the first case, i have a Problem with entering password, for each partition on encrypted disk, i must enter my password.(For 3 partition 3 times)
And in the second version to get i nowhere.
Code:
Cannot login as root or any user.
Message "xsession login to root disable".
Short version:
Ex employee logged into to box and changed the root password, trued to start in single user mode, but not coming right
Long version:
Tried changing the directories to /usr/bin and /sbin but didn't work either.
I just installed a clean install of suse 11.2. I then installed acct, using yast2.
Finally I did:
sudo /sbin/chkconfig psacct on
sudo /etc/init.d/psacct start
So far so good. The problem is that if I know do:sudo /usr/sbin/sa I only see root processes. None of the user processes seem to show up. If I run it with -m flag, I just see a total and a root row, no users show up at all. But I do have user accounts on the machine, and I am working in one of them (only root when necessary).why, or what to do about it? Is there something else that has to be configured? As I understand it, sa -m should show a summary for all users, not just for root. I want to be able to see how much time different users are using.

View 7 Replies View RelatedWhat is the best way to install software in a linux machine if you dont have root permissions. I know that we can use few variables like PKG_CONFIG_PATH and switches like --prefix with configure to get a software installed in a local directory, but sometimes when there are recursive dependencies it is becoming tough for me to install all the packages manually. Is there a better automated way? What I meant by recursive dependencies is: to install package A, I should install package B, which in turn requires package C to be installed.
View 2 Replies View RelatedOpenSuSE 11.1 is by far the best SuSE version in a long time. It's generally up to competition or ahead of it. It's admirable, how thoughtful this system is set up, and how clean and fast it is compared to its predecessors. It ssems, that SuSE is fighting its way back to where they came from before the Novell "merger."
Having said that, it is even harder to understand, IMHO, why the installer doesn't support encrypted root partitions. Of course, there is a manual solution:
http://en.opensuse.org/Encrypted_Roo...ith_SUSE_HOWTO
However, this HOW-TO doesn't explain how to combine LUKS encryption with LVM on a RAID-1 system, as described for Slackware 12.2 here:

Is there a similar guide anywhere available for OpenSuSE 11.1?
If not: Would it be possible to do all the low-level setup work, like partitioning, setting up the logical volumes and encrypting everything, with Slackware, following the document above, and then install OpenSuSE 11.1 on that system? Would that work?
I am a layman to suse Linux. I have installed suse linux 10.2, I forgot the root user name n password. I went through some of the existing threads regarding this issue but in no avail.I dono wat boot-loader I'm using there is no sign of any boot-loader (either grub nor llo).I tried ma hand in fail-safe mode also, it is also asking for login id. Is there any way to reset the same. As I have some imp file inside.
View 6 Replies View RelatedI bought SuSE 8.0 professional a long time ago, while living in Germany. I have an old German laptop that currently has Win2K installed, and I would now like to replace Windows with Linux on it. The computer boots the initial CD fine and gives me a number of installation choices. If I do not add a "root=/dev/hda1" to the parameters it stops the installation with a "Kernel panic: VFS: Unable to mount root fs on 08:01" and if that line is there the error message changes to 03:01.
Is this because the hard drive is already formatted to NTFS? Is there a way to delete the partition and create a new one from the Linux installation disks?
Accidently ran rm -rf while the pwd was /home/user-name
Now I'm unable to run any command whatsoever as root, ls,vi,cnf whatever, they don't work.
However the commands work as normal user.
I can guess that the files with root ownership in the home folder were deleted but I would like to revert everything back to normal and would like to know how to solve this problem.
I just installed opensuse 11.1 with only the standard user account, not root account. Therefore, my question is regarding this ... is safe running linux with no root account? Should I create a root account for adminstrative purposes? If so, how can I do that?
View 3 Replies View RelatedAfter something happened in SUSE Studio, in any appliances I build the owner of /home/tux/Desktop is root which makes impossible to create desktop icons. This happens even in those appliances which previously were build normally with normal ownership (i.e. tux as owner of /home/tux/Desktop). Something changed abruptly and in all these appliances the ownership of this folder changed.

Yesterday evening I attempted to reset the root password by booting from the install CD and using VI to clear the root password in the passwd and shadow files. I then rebooted, and the system has halted with an 'FSCK failed. Please repair manually and reboot' error, with a prompt to 'Enter root password' below. But of course the root password isn't known (I had expected it to blank after editing the passwd and shadow files, but it doesn't work), so I have no way of logging on.
View 6 Replies View RelatedI recently tried a frugal/poor mans install of knoppix that I placed in a folder in the root partition of /home (hda7) in opensuse 11.3. I decided to delete the folder and contents. The hard drive was busy for several minutes and after it was finished, I checked the disk usage and found that / was at 97% capacity, up from what was 10gig of free space. I could not find any traces of the deleted folder or its contents, so I used puppy linux and ran e2fsck on the / partition. Puppy linux reported 1.9gig free space and opensuse reported .5gig free space. My concern is if the deleted folder is taking up space in the root partition that I can not locate and why the difference in reported disk space usage in hda7. Also, if more packages are installed, where are they placed (/ or /home)?
