Package: logcheck Version: 1.2.20a Severity: important Since logcheck changed to run as user logcheck, the error mails of the cron daemon end up in /var/mail/logcheck where nobody reads them. Mails for logcheck should be aliased to root like all the other mails of system accounts. I was searching for a long time what was wrong with my logcheck not delivering any mails. The lock directory was

How can I prevent Samba clients from changing the group ownership of files? With the security mask parameter I can prevent Samba clients from changing some permission bits, but I can't find a parameter to prevent changing the group ownership

Hi, I'm needing to expand a LUN on my EMC CX4-120 SAN. (Well I already had done it). On this LUN I had a PV of a cLVM VG. Know I need to run pvresize on it. Has anybody done this on a cLVM PV ? I'm trying to rescan the devices, but I can't "see" the new size. And, googling on it I can only find RHEL5.2 responses. Thanks in advance,

Hi@all System: 2 Server nodes connected to a SAN storage (shared LUNs). Shared storage holds a Volume group (lvm2) with all my hvm guests. Live migration works nice. But snapshots from logical volumes only usable, when i first deactivate logical volume on the second node - otherwise errors in metadata came up and snapshot is broken/inconsistent. both xen 3.3 are installed on ubuntu 8.04. can

Hello all We are looking into ovirt for several weeks now and i have to say that it looks very promising. Our current environment is based on a lot off shell scripts and xen. We would like to move to ovirt but there are some things we would like to have working before moving. 1. using FC, san and clvm for storage 2. The ability to migrate virtual machines when we have to do maintenance on a

Guys, I have setup my hard disc with 3 partitions: 1- 256MB on /boot; 2- 2GB on / for my dom0 (Debian 5.0) (eth0 default bridge for guests LAN); 3- 498GB exported with vblade-persist to my network (eth1 for the AoE protocol).

I'm desparately looking for more ideas on how to debug what's going on with our CLVM cluster. Background: 4 node "cluster"-- machines are Dell blades with Dell M6220/M6348 switches. Sole purpose of Cluster Suite tools is to use CLVM against an iSCSI storage array. Machines are running CentOS 5.8 with the Xen kernels. These blades host various VMs for a project. The iSCSI

Hi there, I am desperately trying to build a suitable wine.conf, but somehow I just don't manage to. I have been reading through different wine documentation and help pages. I used winecheck to try to figure out what is wrong. However, winecheck tells me constantly that I have to configure the paths of my drives in a special way: /my/mount/point. I tried to apply that (of course not

Hi. I''m using Xen on RHEL cluster, and I have strange problems. I gave raw volumes from storage to Xen virtual machines. With windows, I have a problem that nodes don''t see the volume as same one.... for example: clusternode1# clusvcadm -d vm:winxp clusternode1# dd if=/dev/mapper/winxp of=/node1winxp clusternode2# dd if=/dev/mapper/winxp of=/node2winxp clusternode3# dd

Hello everybody, I am in the process of setting up a really cool xen serverfarm. Backend storage will be an LVMed AoE-device on top of DRBD. The goal is to have the backend storage completely redundant. Picture: |RAID| |RAID| |DRBD1| <----> |DRBD2| \ / |VMAC| | AoE | |global LVM VG| / | \ |Dom0a| |Dom0b| |Dom0c| | |

Hi, I''m curious about how you guys deal with big virtualization installations. To this date we only dealt with a small number of VM''s (~10)on not too big hardware (2xquad xeons+16GB ram). As I''m the "storage guy" I find it quite convenient to present to the dom0s one LUN per VM that makes live migration possible but without the cluster file system or cLVM

I have a system with a large LVM VG partition. I was wondering if there is a way i could share the partition using nbd and have the nbd-client have access the LVM as if it was local. SYSTEM A: /dev/sda3 is a LVM partition and is assigned to VG volgroup1. I want to share /dev/sda3 via nbd-server SYSTEM B: receives A''s /dev/sda3 as /dev/nbd0. I want to access it as VG volgroup1. I am

Please tell me if I am wrong : Xen needs LVM to perform domU snapshots and snapshots must be performed by dom0. By the way, a LVM volume group should not be used by more that one kernel at the same time. So if we use a SAN storage, one volume group should be activated on only one server and deactivated on the others. But if we do that, it should not be possible to perform live migration of

Hi Everyone, I am going to get a storage server which will be connected to my Xen hosts via iSCSI/Ethernet. I wish to use LVM for the DomU disks. The storage server will have a RAID10 array, and 2 Xen hosts will connect to this (Each will have a 50% share of the RAID10 array, space wise). What is the best way to go about this? Should I: a) Split the RAID10 array into 2 partition on the

Hi all, We are running CentOS 5.2 64bit as our file server. Currently, we used GFS (with CLVM underneath it) as our filesystem (for our multiple 2TB SAN volume exports) since we plan to add more file servers (serving the same contents) later on. The issue we are facing at the moment is we found out that command such as 'ls' gives a very slow response.(e.g 3-4minutes for the outputs of ls

Hello all. I would like to canvas some opinions on options for shared storage in a Xen cluster. So far I've experimented with using iSCSI and clvm which mixed success. The primary concern I have with both of these options is that there seems to be no obvious way to ensure exclusive access to the LUN/device to the VM I want to run. On a couple of occasions during my playing I've
