I run a linux cluster with infiniband qdr as the cluster link connection. My lustre MDS server is reflecting as not health. It is reflecting an LBUG error.It is giving me an error on the mds server. the error is as follows - mds kernel: Lustre: 5147:0o2iblnd_cb.c:1785:kiblnd_close_conn_locked()) Closing conn to 172.16.193.193@o2ib: error -116
View 1 RepliesWhenever i do a cold startup (as opposed to a restart), i end up with a repeatable i/o error after roughly 5 minutes. This completely renders the system useless, and i'm talking to myself about raising elephants. I can _always_ restart right after the incident, and it _always_ starts up and i can use linux without incident for _days_.
What would do this? Is there a log i can peruse that might offer insight?
Also, this is a new sympton as of the last 2 kernel updates.
Actual solution:

I am implementing an automated backup scheme so I created a shell script which first creates SQL dumps for all MySQL databases, then retrieves all websites from the /var/www directory of a remote server. The latter is working as I am using rsync to get the remote files.However, the MySQL dumps being retrieved are the ones from the local server which is not what I want. I want to get the SQL dumps from the remote server as well.I have a tunnel between the local and remote server which I can connect to without using any password (I added the public key to the authorized_hosts), so I tried to add the following code to the script:
ssh user@192.168.x.xxx
I then attempted to retrieve the SQL dumps and exited from the remote server. However this does not work as I still have to enter exit manually in the terminal for the SQL dumps to be retrieved from the remote host. I don't know why this is happening. This is what the script is trying to do:
//connect to remote server
ssh user@192.168.x.xxx
//retrieve SQL dumps
[code]...
Is there a way to connect to the remote host AND run the script's code on THAT remote host?

I'll try to describe my question as clear as possible.
- I have purchased a domain name : *****.md
- In the panel of registrar I have only the following options to complete :
Primary NS Hostname
Primary NS Netaddress
Secondary NS Hostname
Secondary NS Netaddress
- At home I have :
a)a WiFi router that is getting an external IP from my ISP provider (internal address of router is 192.168.1.111); External IP from ISP is STATIC.
b)a computer which I use as server (ubuntu 10) with internal IP 192.168.1.100 (I get it by DHCP from Router but it can be set as static of course);
- On server are installed :
a) Apache + Mysql + PHP
b) Ftp serv
c) Webmin
d) SSH serv
e) Bind9 DNS serv
- On my WiFi router there is an option "Forwarding -> Virtual servers" where I setup the ports 53 + 80 to forward to my server and I can access from external my site by IP.
All I want is to have my site *****.md to run on my server and to be visible to external world.
I have searched Google for last 2-3 days for a solution but everything I try doesn't help.
I'm new in Linux ( 1 week probably). Everything except DNS server Bind I was able to setup and are working well.

I have a linux server that is running on Redhat 4 with several applications such as coldfusion, postgres, phppgadmin, samba and apache. I would like to update the server to Redhat 5, but I am afraid after the upgrade, some of the applications might not work correctly, so I want to test it in another server first.
I am thinking of create another server that just the same as the one I have now so that when I do the upgrade, if I run into any bug or drivers missing, I can fix it and prepare before hand for the real server. So can somebody please show me some direction on how I am going to create a mirror server of the current server I am having now. I don't know where should I start.
