Hello all, we have a new setup with xen on centos5.3 I run drbd from lvm volumes to mirror data between the two servers. both servers are 1U nec rack mounts with 8GB RAM, 2x mirrored 1TB seagate satas. The one is a dual core xeon, and the other a quad-core xeon. I have a gigabit crossover link between the two with an MTU of 9000 on each end. I currently have 6 drbds mirroring across that

Hello all fellow CentOS users! I have a working xen setup with 3 paravirt domUs and one Windblows 2003 fully virt domU. There are to virtual networks. As far as I can tell in the paravirt Linux DomUs I have gigabit networking, but not in the fully virt Windows 2003 domU.... Is there a setting for this, or is it not yet supported? I run xen-3.0.3-64.el5_2.3 Kind regards, Coert

Hello all, At our office a have a server running 3 Xen domains. Mail server, etc. I want to make this setup more redundant. There are a few howtos on the combination of Xen, DRBD, and heartbeat. That is probably the best way. Another option I am looking at is a piece of shared storage, a machine running CentOS with a large software RAID 5 array. What is the best means of sharing the storage?

Hello all, Windows......................... I have installed a Windows Server 2003 fully virt domU with the GPLPV drivers. The network settings reset on every restart of the domU. Weird STOP errors keep popping up.... Was I naive to think you can run a Windows server on Xen? Are any of you guys doing it successfully? Am I better of just installing windows server 2k3 on bare hardware? Just

Hello all, I am running drbd protocol A to a secondary machine to have 'backups' of my xen domUs. Is it necessary to change the xen domains configs to use /dev/drbd* instead of the LVM volume that drbd mirrors, and which the xen domU runs of? regards, Coert

Hello all, About a year ago I set up a mail server on CentOS using this howto: http://wanderingbarque.com/howtos/mailserver/mailserver.html I managed to add amavisd-new with clamav and spamassassin. It runs very well, but it runs on CentOS 5.2, and if I try to upgrade, amavisd-new and clamav break. we are now also at the point where a backup mx will need to be implemented. If necessary I am

Hello all, I have yesterday after some typos, sent my ext3 RAID5 array to the void... I want to recreate it now, but I read on http://wiki.centos.org/HowTos/Disk_Optimization that you can optimize the filesystem on top of the RAID. Will this wiki article be exactly the same for XFS? Is it worth the trouble to also create an LVM volume on the RAID array? Regards, Coert

Hello all, Firstly, I have checked on google, and there are indeed howtos on this subject. Have any of you done this or something similar on CentOS? If so, could you send me the configs maybe? How can I find out if the centos version of samba supports extended ACLs? I ran a modinfo xfs, and XFS supports it. I want to set up a samba server that authenticated to AD. I have that up and running,

I am trying to upgrade my system from 500GB drives to 1TB. I was able to partition and sync the raid devices, but I cannot get the new drive to boot. This is an old system with only IDE ports. There is an added Highpoint raid card which is used only for the two extra IDE ports. I have upgraded it with a 1TB SATA drive and an IDE-SATA adapter. I did not have any problems with the system
