I had a server running Centos 5.5, which i have Webmin installed.. The other day i saw that there were updates available so i installed them, and now i have Centos 5.6 installed. I just had to reboot my server to move it, and now it wont boot. It is freezing at "Starting xend:"
View 5 Replies View RelatedI just finished installing CentOS 5.2 x86_64 on a Dell Dimension 3100 (Pentium 4 with 64-bit support). On the first boot, after completing the final config steps (firewall, SELinux, time server, etc), the boot hangs on "Starting xend:". I have completed a successful installation on another Dell machine (different processor), with the same installation options (I recorded all of the steps and followed them for the second installation).
My boot commands in grub are:
root (hd0,0)
kernel /xen.gz-2.6.18-128.el5
module /vmlinuz-2.6.18-128.el5xen ro root=LABEL=/1 rhgb quiet
module /initrd-2.6.18-128.el5xen.img
when I reboot the server with centos 5.5 the SMB deamon doesn't start?

Well I want to know if that module is compatible with my centos 5 because it appear that run in kernel 2.6.X. is compatible ?

View 16 Replies View RelatedWe have a Centos 5.6 server mounting two iSCSI volumes from an HP P2000 storage array. Multipathd is also running, and this has been working well for the few months we have been using it. The two volumes presented to the server were created in LVM, and worked without problem.We had a requirement to reboot the server, and now the iSCSI volumes will no longer mount. From what I can tell, the iSCSI connection is working ok, as I can see the correct sessions, and if I run 'fdisk -l' I can see the iSCSI block devices, but the O/S isn't seeing the filesystems. Any LVM command does not show the volumes at all, and 'vgchange -a y' only lists the local boot volume, not the iSCSI volumes. My concern is that, the output of 'fdisk -l' says 'Disk /dev/xxx doesn't contain a valid partition table' for all the iSCSI devices. Research shows that performing the vgchange -a y command should automatically mount any VG's that aren't showing, but it doesn't work.
There's a lot of data on these iSCSI volumes, and I'm no LVM expert. I've read that some have had problems where LVM starts before iSCSI and things get a bit messed up, but I don't know if this is the case here (I can't tell), but if there's a way of switching this round that might help, I'm prepared to give it a go.There was absolutely no indication there were any problems with these volumes, so corruption is highly unlikely.
Centos 5.3 includes Ext4 and improved support for encrypted file systems but it appears to be aimed at laptop/desktop systems, in that a password must be entered at boot time.
Is it possible to have a server with an encrypted root file system boot up without entering a password?
Mandos will do it...
http://wiki.fukt.bsnet.se/wiki/Mandos
...by serving up the password from another server...
http://packages.debian.org/squeeze/mandos
...to a client loaded into the initial RAM disk environment...
http://packages.debian.org/squeeze/mandos-client
...but it's not available on CentOS, and is only in Debian unstable.
Is there a similar (or any) solution for CentOS?
In particular, I'm envisaging encrypted virtual machines being served passwords from their virtual host.
Alternatively, the data that *really* needs to be protected could be encrypted while the system core remains unencrypted. But then the keys to decrypt the file system must be stored in the unencrypted portion, so this is not an effective method.
I have Centos 5.3 on our server When I log-in in webmin I have a message "Warning - Your system is actually running CentOS Linux version 5.3."

If I do, is it going to change any configuration on our server?

View 5 Replies View RelatedI have a CentOS 5.5 system that I am able to run fully virtualized 32-bit VM's on just fine, but I have need to run some 64-bit VM's on it. It has a "paravirtualized" option that might possibly work, but it wants a network install path, and I am not sure if this is the actual solution. When I go to create the VM I only have i686 and xen for options on the virtualized method, is there a way to add (I am presuming) amd64 in here somehow? The CPU is definitely 64-bit. My google-fu hasn't found results for me yet.

Using the EPEL Repository, I went in and installed Cobbler to my DHCP/Gateway box.Everything went smoothly on the installation front. I went ahead and modified the cobbler settings file (/etc/cobbler/settings) to point to my server IP (same box), and then got tftp running properly. Now here's the problem.Normally, you need to run `cobbler check` to find issues and correct them. I run that, and all I get is blank. Nothing. It just hangs at the prompt until I kill it using CTRL+C.When I CTRL+C from the hanging, it states "cobblerd does not appear to be running/accessible"...
Code:

I'm attempting to get freetds and sybase up and running on my centos server, mainly for nagios - MSSQL checks. I've installed freetds freetds-devel ok but am having issues getting SYBASE installed. I've had a go via cpan but get a failure on the sybase environment variable. I've set it to /etc where the conf file is located as well as trying /urr/lib64 for the tds libs, but no joy. Has anyone had much luck with this on centos?

I am setting up a CentOS server that has no screen connected, and only has 2 Tesla cards. I have created a minimal xorg.conf and xinitrc file that doesn't load mouse or keyboard, and only creates two screens, one for each card at 320x200x24 bit. This is so I don't waste VRAM on a framebuffer I can't see.
I modified the xinitrc to just load tdm and nothing else as GNOME is a RAM hog. I am then using this setup to render stuff offscreen using OpenGL into FBOs which I read back to CPU and process. Currently for development I just run startx& when I login. I now want to know how to set x server to start automatically at boot. The CentOS docs say that it will try to load the GNOME login manager. The thing is that I don't want a login manager as it is useless as I login remotely via SSH.So:
1 - how to enable automatic x server in CentOS (im used to Ubuntu so not sure how to do this on Red Hat variants)
2 - leave x server running without starting login manager
What would be the best way to determine memory consumed by each application running on the server?

We've been experiencing sudden host server crashes minutes after starting a fourth virtual machine. Our setup looks like:
Dell Poweredge T300
1 x Intel Xeon X3323 Quad Core 2.5 ghz
16 GB Ram
CentOS 5.3 (64 bit)
Server is running a stripped down version of CentOS 5.3 (64-bit), running only the built-in Xen Virtualization Environment. There is no other services running on the server (not samba, httpd, sendmail, cups... nothing except Xen) We've created several virtual machines, and as long as we don't start a fourth virtual machine everything runs smoothly (impresive hardware).
Each virtual server is configured as:
PARAVIRTUALIZED
1 Virtual CPU
1 GB RAM
However, 5 minutes or so after starting a fourth virtual machine, the entire host server crashes and restarts itself. Are we limited by the number of cores on the host machine CPU (4 cores)? 1 for the host and 3 for virtual machines? We've read in forums about other Xen setups running up to 11 virtual machines on less powerful hardware? (a dual core server). Should we be using FULLY VIRTUALIZED virtual machines instead? Is the number of XEN virtual machines in fact limited by the number of cores? If so, how can someone run several virtual machines on a single core host?
By the way, we were replacing a previous Dell Server (Poweredge 2600 with 512 MB Ram and a single Xeon single core processor running Open Virtuozzo). We were able to run up to 16 virtual machines at the same time. Of course none of the machines endured hard work (testing environments, etc). But hey, my point is that we expected to get a much higher number of virtual machines on this new hardware.
