similar to: HowTo copy a Logical Volume to another LV

I have searched the list, and don't see this covered or didn't search for the right words. I'm running CentOS 4.8 and have some DVD's for 5.4. I have a lot of customized and additional software installed and would like to avoid starting over with a scratch install. After the upgrade from the DVD I would do a yum upgrade to 5.5. Is this a workable (and safe) thing to do? What

Hi, We are having a problem between Linux 2.6.9-prep #12 SMP Mon Dec 6 12:08:34 CST 2004 x86_64 x86_64 x86_64 GNU/Linux (Samba version 3.0.9-1.fc3) and MAC OS X 10.3.5 Samba version 3.0.0rc2 Basically the issue is that the Mac reports the Linux share as being full, and won't allow files to be copied. We are able to work around it using this method: Create a folder on the Linux

I have a machine with two swap partitions (sda2 and sda8). Both will have none as mount point. When I try to use puppet (using mount type) for managing fstab I get problems because "name" in both instances (i.e. mount path) will be "none". How should I fix this within puppet? Regards Halvard Moe

Hi, As someone new to puppet I''m trying to work out the best way to manage different filesystems and logical volumes on different servers. Specifically I would like to be able to define on a series of nodes different LVM logical volumes to create and mount. I''m trying to do this at the moment with a define of the following type: # Manage a partition and create if needed.

I have full virtualized CentOs with disks ike this ------------- /dev/vg00/lv_root / ext3 defaults 1 1 /dev/hda1 /boot ext3 defaults 1 2 --------------- I try change my it to paravirtualized, but after reboot I got kernel panic, because /dev/vg00/lv_root wansn''t found. ----------------- this is my grub

I created a 1TB RAID1. So far it is just for testing, no important data on there. After a reboot, I tried to mount it again # mount /dev/mapper/vg00-btrfsvol0_0 /mnt/btrfs0 mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg00-btrfsvol0_0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or

Hi to the ML. I''m new to VLAN configuration, and combining it to XEN is a bit difficult. I want to use VLAN because it''s possible to "arping" from a domU to an other, and VLAN looks like; the only solution to prevent that. May be I''m wrong if someone got a solution, I may be interrested. I''ve also tryed ebtables, but nothing to prevent arp

I read your version of the procedure and it looks like you want to skip the pvmove. That's fine, but it means more downtime (an unreliable estimate is one minuted per GB). In that case, you don't even need the snapshot. You won't need a point in time

First let me say that I'm not a sysadmin, but am simply wearing that hat this week so please excuse my ignorance. I need to temporarily move some virtual servers from a CentOS-KVM platform to a CentOS-XEN platform while I do some upgrades to the CentOS box. I've created a local LV, and used DD and SCP to transfer the block device from the VKM machine to the XEN machine. For quite a

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Is there some limit on the size of a file system which can be shared via samba? I'm trying to set up a file server with a 100GB shared partition and it doesn't want to work. I'm running Fedora Core 4, and Samba Version 3.0.14a-2.

I have a CentOS 4 server at home where we store all our data, I wanted to get some idea of the amount of traffic going into and out of the server by protocol so I installed IPtraf.. When I run it from an ssh session it looks fine but when I run it directly on the server console its doesn't look right at all.. It doesn't seem to layout correctly.. Is there something I need to do

I tried to start a linux hvm domain (just for testing some things compared to a pv domain), and it didn''t start up. I then did a ''xm shutdown'', which didn''t work, then a ''xm destroy'', and from then the ''xm list'' function just hung. I then restarted xend, and ''xm list'' works, but now when I try to start the

Hi, I was at the Puppet talk at Oscon and I would like to try using Puppet for PXE on RHEL machines and I was wondering if there are standard minimal Kickstart recipes from which Puppet can then take over. Thanks, Jason van Zyl jason at maven.org

I am trying to install CentOS from an ISO image file but the installer does not see a CD-ROM drive. The VNC viewer works but the CentOS installer indicates "Unable to find any devices of the type needed for this installation type." Then it prompts with "[Select driver] [Use a driver disk] [Back]". I have tried several variations of the "disk" paramater, all

I did something stupid when setting up a server which is now live. I think I'm stuck. I set up swap on Raid1 which is decidedly non-optimal. I'd prefer 2 independent swap partitions at the same priority. Here is the set up: /dev/sda1 + /dev/sdb1 -> md0 (raid1) md0 -> VolGroup00 VolGroup00 -> VG00LV00(/), VG00LV01(/home), VG00LV02(swap) I've gotten as far as : Turning

Hi, I recently installed centos for the first time and I like it! Also, I just started working with lvm. The following warnings are genertated whenever I run one of lvm commands on the external usb disk (MyBook by Western Digital). * What could be the source for those messages? * Should I worry about them (writing into the created LV's seems to work)? * If yes, how to fix them?

Came across a strange problem, I have a software raid1 with LV sitting on top.

hello, i am a newbie to this list and i don't know if this has been posted before (if so, plzz accept my apologies) i just noticed a nice mini-howto on ext2-ext3 conversion at http://www.symonds.net/~rajesh/howto/ext3/index.html i think that maybe a link can be added to this after the download section... cheers Sayamindu *********************************************************************

I have an smbd process that is using alot of cpu on HP-UX 11.11 using Samba 2.2.3a. It looks like the application on the client side is trying to open and close a ton of files, many of which do not exist. When I do a trace on the smbd process, I see repeated calls to lstat64 to what looks like all of the device files on my unix server. Here is a little bit of the trace. It goes through all of the
