Adding an existing RAID 1 to a new Ubuntu Server?
location: ubuntuforums.com - date: May 4, 2009
Our small business has been using "SME Server 7" as our file server for several years now. We would like to change our server's OS to Ubuntu, but would need to do it without loosing the critical data on the array.
The current set-up has 3 hard drives:
The first holds the root partition, and the file system.
The other two drives are members of a RAID 1 array, and hold all of the shared files (for our employees).
The SME Server installer created the array automatically during the install, so I don't know which variety of array it created.
What is the best way to:
1. Determine if the existing RAID array is compatible with Ubuntu?
2. Proceed with the installation so the old RAID array will work with the new system, but not be overwritten in the process?
Uploaded files from PHP app are dissapearing on new ubuntu server
location: linuxquestions.com - date: March 28, 2009
Does any one know which log to look at on a ubuntu server of this type of problem. I edited the PHP.ini to allow files larger than 2M.
upload_max_filesize = 1024MB
upload_tmp_dir = no value
user_dir = no value
post_max_size = 1024MB
Before I made changes to php.ini I was getting a file not found errors. Now the PHP app seems to send the file but I cant find it any were on the server. I have set the /var/www/vault/vwdmo directory to 777
with chmod 777 vwdmo.
drwxrwxrwx 2 synchro synchro 4096 2009-03-27 14:30 vwdmo
I use PHPrunner4.2 to generate the code it work on Red Hat 4 but I need to get it to work on Ubuntu 5.2.6
Thanks for any help.
Problem configuring RAID 5 under Ubuntu Server 9.10
location: linuxquestions.com - date: January 16, 2010
I have a problem configuring a RAID server under Ubuntu 9.10 (kernel 184.108.40.206) with mdadm (v220.127.116.11). First I had some hardware issues that finally got solved by using another motherboard. Now I am dealing with the software part.
In order to ease things, I am trying to configure a RAID 5 with three partitions in one disk. I have two HD's, one IDE where the OS lies (recognized as sda), and another where I intend to build the RAID (recognized as sdb). In this second drive I have made three partitions (sdb1, sdb2 & sdb3) of the same size. For this I've used
sudo fdisk /dev/sdb
and made three partitions of the same size, then changed the type to "fd". Then format each one with
sudo mkfs.ext4 -m 0 /dev/sdb1
sudo mkfs.ext4 -m 0 /dev/sdb2
sudo mkfs.ext4 -m 0 /dev/sdb3
After that I've created the array with
sudo mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/sdb1 /dev/sdb2 /dev/sdb3
Finally formatted it with
sudo mkfs.ext4 -m 0 /dev/

Setting up a new Ubuntu Server 12.04 box
location: ubuntuforums.com - date: October 1, 2012
I'm in the process of setting up a new Ubuntu Server 12.04 box. I am somewhat of an Ubuntu noob, but I am learning.
I have the basic server installed, and I even got minidlna to talk to my TV over ethernet so I can watch movies.
But now I need expert guidance on a couple of issues.
First off, this Ubuntu server is replacing a Windows Server Hyper-V host, so I want to build some virtual machines on this box (both Ubuntu Desktop machines and a variety of Windows servers and desktops). The box has 16 gig RAM and tons of HDD so that's not an issue.
What I need advice for is a) is there a decent step-by-step howto build a VM in KVM that encompasses both Windows and Linux guests? I've looked a quite a number of howto's online and none of them seem complete or consistent (I've found several that say "Ubuntu Server" as the host, but they insist of using a GUI)
Also, this machine has three NIC cards. What's the best way to automatically assign them to virtual machin
Confusion re: new Ubuntu server built with several (full) hard drives
location: linuxquestions.com - date: January 9, 2014
I'm building an Ubuntu Server based media server. I did the install with a single empty drive installed. Once the initial install was complete, I connected 8 other hard drives (most of which were already full of music and/or video files).
The first puzzling thing was when I tried to open one of these drives (which was automounted at boot up.) I was required to authenticate. "An application is attempting to perform an action that requires privileges." Why?! At first I had no idea what to use as the password. I hadn't password protected these drives. Then it occurred to me - use my Ubuntu password as though this was a sudo situation. (Was it? It worked.)
Next, I wanted to get rid of all the NTFS partitions and migrate everything over to ext4. sdb1 had nothing of value on it, so I deleted it in gparted, then created an ext4 partition which I would then use to copy over all the files from sde1. When finished, I would delete the ntfs partition on sde1, create an ext4 partit
Can't login from Windows 7 to new Ubuntu server box
location: ubuntuforums.com - date: March 7, 2015
Totally new to Ubuntu. My company unloaded a lot of old PC hardware and I nabbed a Dell Precision 3500 Xeon machine, which I am trying to set up as a personal web server.
I searched for tutorials on this and ended up following this one:
I easily made it to point where I can paste the ip of the new server in the address bar of IE on my Windows 7 (64-bit) machine and get the "Welcome to nginx on Debian!" message. So far, so good.
Now, just so this will be a "black box in a closet server", I am trying to login to the server from my Windows 7 machine and I am not having any success...Started out trying it with Putty and then Cygwin and then combo of the two, but I only end up with "Network Error: Connection refused" all the time
I've tried adding port 22 in my router to port forwarding, but no success with that.
Please help! I can't seem to find the magic tutorial for that one... (the arste
How can I set RAID 0 using Ubuntu Server 12.04
location: linuxexchange.com - date: January 1, 1970
I have a server which installed 2 HDD (500 GB each).
I would like to install Ubuntu Server 12.04 on it but when I partition my disks like :
"Configure software RAID" > YES > "Create MD device" > RAID0 > and check both "/dev/sda1" and "/dev/sdb1" > continue > Finish. Now I got
RAID0 device #0 - 1.0TB Software RAID device #1 1.0
512.0 B unusale SCSI1 (0,0,0) (sda) - 500.1 GB ATA MB0500EBNCR #1 primary 500.1 GB K raid SCSI1 (0,0,0)
(sdb) - 500.1 GB ATA MB0500EBZQA #1 primary 500.1 GB K raid
Then I select "Finish partitioning and write changes to disk".
After that, I got an error message
No root file system
No root file system is defined.
Please correct this from the partitioning menu
Could you please tell me, how can I solve this problem?
Thank you for every answer.
PS. This Machine will be used as File Server
How do I mount Raid 1 disks on an already existing Ubuntu server?
location: ubuntuforums.com - date: October 16, 2014
I've just got a (ubuntu) server up and running for the first time ever on my old ex-NAS computer which won't boot off a usb. Disk wise it has a 200GiB (SDA) for the server, on a 20GiB partition, I believe that there is a swap file in there as well, and two 500GiB (SDB+SDC) hard drives. At the time of installation I set up these two as Raid 1 (I think because I haven't seen them - softwarewise - since).
I need to set these up for my storage notions, which I suspect means that I need to mount them. I don't want to trash what I've done so far and I'm sure this has been asked a dozen times before but I've been googling for the last 16 hours and all the Raid references are about setting up the operating system on the Raid disks. That's not what I want and this old motherboard I'm using has been passed by by all but server installations.
I would be so grateful if someone can point me toward the solution. In an ideal world that would be on Youtube, because that's what I used to get
New here and new to Ubuntu Server
location: linuxquestions.com - date: December 21, 2008
Hi all! I just loaded Ubuntu Server on a machine that I hope to set up as a game server. It's my first linux box and I'm starting with no experience with the OS.
I tried to load Ubuntu desktop first, but after the install it wont reboot to the startup screen
It's a dell computer with a celeron chip, 1gb ram and 30gb of drive so it should have worked..... but I tried 3 times to load desktop and then switched to server.
I'm a total nOOb with linux and I'm sure I'll have more questions for you, but heres my first:
will loading a GUI make setting up a game server easyer? and if yes, how do I load and start a decent GUI?
