View 1 Replies View RelatedI'm gonna set up a HA-cluster with the help of DRBD. I have installed DRBD and it's working on the Primary node, I synced them and formated it to ext3 and mounted it successfully on the Primary.
When I'm gonna mount it on the Secondary node it just tells me that I need to specify a filesystem.. so it looks like is hasn't been synced properly or something but both nodes are up to date.
This is my drbd.conf:
Code:
global {
usage-count no;
}
resource dbcluster {
[Code].....
and could mount it without any problems on dbcluster1, but it doesn't work on dbcluster2.. according to the documentation and various howtos I'm suppose to be able to use it, mount it on both nodes etc. unless I've missed something.
Does anyone know if there is something else I need to do to get it running properly on the Secondary?

Where is this setting, so I can change it?
I have a secondary slave dns server setup, it has transferred all the records from the primary master.But when I run a few checks from outside using tools on the net it says:Tried to fetch SOA record for domain, but DNS server ns2.domain.com returned error code Refused.I disabled iptables, and tried again, same result. So I think it is something in the named.conf file? I appreciate any extra set of eyes on it. Just feel like I'm so close!

I'm pensioning off my 10-years-old home server and replacing it with an Ubuntu 10.04 box. The two storage devices are a Western Digital Caviar Green 2.0TB HD and an Intel X25-M 34nm Gen 2 80GB SATA II 2.5inch SSD (the box has 8GB RAM and an i5 750, if it matters).
I don't care much about boot times (since I don't plan to reboot all that often;-); the main frequent, performance-demanding task will be (re)building large open source C or C++ software packages from sources (as an open source contributor, I do that often).
So, I thought I'd keep the SSD as the secondary drive and the HD as the primary one, using the SSD mostly for the files that can otherwise demand a lot of seeking (esp. in a parallel make).
However, the friendly vendor (perhaps more experienced in Windows systems than in Linux ones) thinks the "normal" way to configure the machine would be with the SSD as the primary drive. I'm pretty rusty on configuring and tuning systems, so, I thought I'd better double check on SuperUser.
I just installed primary dns server now want to install new slave server so that in case if primary fails secondary can take requests.
View 3 Replies View RelatedI have a CentOS 5 server with a 250gb hard drive running close to the maximum space on one of the partitions. 87% of 200gb (/home), roughly. I have a second 250gb hard drive which is completely unused. I just recently did some searching through the forums here and found out about LVM and wanted to implement it. Although the downside is I believe it has to wipe a drive/partition before it can add it as a logical volume.
The process I'm considering following is:
1. add this empty 250gb (SDB) secondary hard drive as a logical volume on LVM and copy everything over from the currently filling up partition on my main hard drive.
2. have LVM add in the old partition on the primary hard drive (SDA)
3. extend my logical volume out to include the old partition. Extending my total hard drive space out to 450gb.
I am trying to set up an X2go server, that lets clients log in on a remote server. the idea is that a school uses old computers as thin clients, and a small server loads an image onto the clients, and then lets them log into a big server in germany using X2go. Does anyone know where i can find a guide or some documentation that would show me how to do

View 2 Replies View RelatedOur primary mail server is Exchange 2003 Standard on Windows Server 2003 Standard - don't shout at me; I inherited it already set up this way.I have a couple of hardware identical redundant servers (HP ML350 boxes), all with very fast 2 or 4 disk arrays, multiple core CPUs and plenty of memory, and I am looking at two potential new additions to the infrastructure.
A secondary mail server is high on my list of priories. I've been well and truly bitten by Exchange in the past and given that this particular box has been running four years straight and that it's mail store is dangerously large, having a secondary mail server in place suddenly makes a lot of sense.
A new Exchange 2010 box is currently being set up, but the secondary mail server will remain in place even when the new Exchange server is brought online, so this won't be a wasted exercise.... I also want a gateway box in place to filter and relay mail to the primary server, or to the secondary server if the primary is unavailable. Currently our outer perimeter is:
ISP supplied CISCO router
Draytek VigorPro 5510 UTM
Untangle running in bridged mode (primarily used for SPAM filtering, URL blacklisting, and very little else) Exchange 2003 sits behind the Untangle box. This is how I want to end up:
CISCO >> Draytek >> Ubuntu gateway >> Exchange/secondary mail server
I know I could replace/remove the Draytek but I want it to remain for several reasons, including lots of VPN dial-in users already configured and that it offers us an additional layer of email antivirus scanning before things hit the Exchange box. No point switching all of our remote workers over to new tunnels unnecessarily...
I have done some research and have started testing a pilot secondary mail server using Ubuntu/postfix DNS is properly set up and MX records and reverse PTR records are all present and correct, and things are looking encouraging so far. Before I go out over deep waters and start to flounder, has anyone who has done something like this got any obvious howlers I should be looking to avoid ?
