Server :: Building A Storage And Vpn?
May 15, 2011
I am trying to figure out the best server configuration for the following:Low power (I want to plug the server in and forget about it)High redundancy of data (I don't want to loose my music and documents!)The ability to stream music + movies to laptop (maybe subsonic or Jinzora)VPN server with IPsec or OpenVPN NAS $800 budget 2TB with ability to add more drives :Unix Server with software RAID (maybe RAID6)
VPN setup on virtual OS via VirtualBox
NAS setup on virtual OS via VirtualBox
My Questions:What would be the best raid configuration if I wanted at least 2TB of data and the ability to add more disks when the space begins to add up?What would be the best OS to use for setting up a software RAID (is a FakeRAID a better solution)?Does it make more sense to separate the VPN and NAS with different OS's?My goal will be to access my data from any computer from anywhere but mostly just my Laptop from work.

I need some advice or tips or maybe your own experiences about building a home data storage or NAS.Here's some thoughts / requirements I think it should have:It should expandable. I'll stick a couple of 1TB HDDs and a little later I'll stick some moreIt should easily integrated to both Ubuntu and Windows 7. Ideally it'll be an integrated part of the filesystem.I'm thinking some sort of RAID as a backing up my data. RAID 1 seems like a such a waste but then again, these days, HDDs are cheap.And when I do add more HDDs, I'd like them to appear as one big storage unit instead of separate drives.Any suggestions and tips on how to go about this is welcome. Questions are plenty: should I go with server hardware or is bigger ATX case and standard hardware enough? I'll need some pointers so keep 'em coming

I'm building one of the backblaze storage pods:
blog.backblaze.com/2009/09/01/petabytes-on-a-budget-how-to-build-cheap-cloud-storage/
I have followed the specs they give exactly and i have almost completed it but I am stuck trying to mount the raids. There are 3 RAID6 and i recieve the same error for each one
Code:
mount /dev/md0 /mnt/raid0
mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
This is what i have done(ill just show one since they are identical except for which drives make the raid of course)
Code:
mdadm --detail /dev/md0
/dev/md0:
Version : 00.90
Creation Time : Thu Mar 4 14:50:11 2010

I am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...

I'm interested in buying a new hardware for my company. The old server (now 10 years old) should be replaced with a new one. Till now, I was looking on different hardware suppliers, boards and different other places. I found a Tyan board [URL]. The hardware spec is quite interesting and the board would fullfill our claims.
how both storage devices will be supported by Ubuntu or Debian??
- SATA-Controller: AMD SP5100
- SAS-Controller: LSI 1068E

Setup1: Two rack mounted servers with a common storage device serving as the home directories for users on the servers. The storage device is a gfs partition mounted on the servers as the home directory using SAS cables. These servers have RHEL 5.4 as the installed operating system.
Setup2: A standard tower server with Debian 6 as the operating system used for tape backups. This has a tape drive connected to it.
Question: How to mount the storage device of setup1 using NFS on the server in setup2.

I'm building an Ubuntu 9.10 home server to essentially backup all my PCs to, serve media, and store other large data (I record music and film). Here's what I have as far as storage goes:
4GB CompactFlash: for OS
2x 500GB WD drives: intended for RAID-1 for backup (which I will in turn back to external drive on a weekly basis)
3x TB Hitachi drives: intended for RAID-5 for media and storage
Both RAIDs will be software-driven. Now, a few questions:
From what I've read, I can benefit from using LVM on top of the RAID. Is this true, and besides the complexity and potential difficulties in recovery in case of disaster, is there a downside to LVM?
Would I benefit at all from using smaller logical volumes on the RAID-5, or should I just make one at the full size of the drive?
Also from what I've read, it seems that XFS may be the best filesystem to use, from a stability and performance standpoint. Should I go that route, then? I suppose that if it IS beneficial to have multiple smaller logical volumes, then there may come a point that I need to shrink and grow these logical volumes, and if that's the case, it appears XFS is out of the question. What's the runner-up; Reiser? I currently have /swap and /home partitions on the CF card. I'd at the very least like to remove the /swap partition and just create a swap file on the RAID-5. Should I move my /home partition to the RAID-5 as well?

In our environment we are using EMC for storage. We are using Qlogic provided drivers and PowerPath and the OS is RHEL5.3. Currently we have 2 Luns connected in one of our server (emcpowera & emcpowerb) and storage team has allocated another 100Gb Lun to that system, my doubt is if I execute "ql-dynamic-tgt-lun-disc.sh" script that would be enough to detect the Lun and see the device under /dev/ as emcpowerc or I need to execute "powermt config" and "powermt save" commands also.

was originally looking to setup some kind of NAS in my house due to the fact that me and my wife both access the same music libraby, photo library etc. and was looking at one of the IcyBox enclosures.I realised that whilst this was a quick and possibly easy way to set something up, it wasn't in keeping with the true geek within so decided to look into setting up a full RAID5 file server. This would then allow me to install and setup various other services such as Web and FTP server, Mail server and DNS server should I ever want to.
I have an old machine (Duron 1GHz I think) with 1GB ram but the only problem is that is doesn't have an on board SATA controller so I was wondering what PCI SATA controller cards work with Fedora? Doesn't need to have RAID capabilities since i'll be using Software RAID anyway, just need a nice cheap Fedora friendly controller card that'll do the job.

I've been running my dedicated server on Ubuntu 10.04 for 300 days non-stop so far (touch wood). I'm planning to purchase a dedicated server to host many large sites. The specs are Sandybridge Xeon with 16 bay x 2TB storage using RAID5 (Adaptec RAID 51645).I don't have experience with RAID, but I read that ext4 can only support filesystem up to 16TB, my plan for the system is to have 32TB of storage. How can I make Ubuntu run this configuration?
Also, can Ubuntu 10.04 recognize the Adaptec card? Going through Adaptec website there is no mention of drivers for Ubuntu (although many other distros are available).

my workplace is switching from Oracle app server to Tomcat. I've never been a sysad, and never administered an app server. So that part is going to be completely new to me.ortunately, I don't have to be the primary on this - but my manager is encouraging me to learn the setup and how to do the job.So, my situation is that my test "server" is a P2 with 256MB of RAM. I know I'm not going to get screaming performance out of it, but all I really need it to do is run my web server and file server to support my Tomcat install on a separate box (P3, 2.8GHz, dual-core with a gig of RAM).
I'm not really a n00b to Linux, so building the system isn't a stumbling block. Which distro, and which version of that distro, is a stumbling block. I know ubuntu is easy to set up, and very popular. If I went that way, should I get the desktop version? Or the server version? I *want* the GUI, but don't require it. And I'm not real certain what they're referring to (hw or sw) when they call it "desktop" or "server".I'm not looking for a challenge to broaden my horizons in terms of my Linux knowledge - I just want something I can set up quickly so I can get on with learning what I need to about the server installation, configuration and administration.

I have builded my kernel through wiki manual, BUT, the kernel-headers rpm-package has not been builded. Now i have only two packages: kernel and kernel-devel. Is that ok? (i think, that it is not ok, because when i build the same version of kernel on x86_64 platform, after rpmbuild command i have kernel, kernel-devel and kernel-headers packages) My CentOS version is 5.2; platform i686; kernel, kernel-headers, kernel-devel packages 2.6.18-92.el5.

I hope this post is in the right area of the forum.I am searching for the right operating system and application(s) to build a cloud data storage server business like Backblaze.Backblaze uses Debian but uses their own custom application to manage the data, uploads, accounts, encryption, etc... So my real question here is: does anyone have any recommendations for existing application(s) I could use on top of Debian to handle this stuff?

I am looking for the best/cheapest way to build a ubuntu server with 8tb of storage hanging off of it.
I don't feel it needs to be hardware raid, so more software raiding swap in and out failed disk drives.
The server itself normal duo core CPU with 2Gb of memory and i would like to have the internal drive of the O/S only.

i have a spare computer and 4 hds and was planning to make this computer a storage server with a media place aswell... i do have some linux knowledge but never used it for this and am not sure how good it will be initially the media files are in an HD with ntfs format which i want to keep as is... but i was wondering what options i had to make a media folder over network where i could browse and watch from any computer in my network ? is it samba my only options or is there a more media like solution for this ? There will aswell other features i was planning to use on it which made me think of linux, for example, svn server, websever with mysql to testing my applications, connection manager, all these i am sure on how to make and setup... but i am not very familiar with samba hence i am not sure if it is the best options for file sharing aswell as media sharing and/or my only option.i also heard that ntfs might be trouble some for linux in some cases

The /var directory is 97% full on my dedicated server:
I would like to know if it is safe to clear it and how to clear it (assuming it will not disrupt/kill server services to do so).
I have Matrix control panel so i can view the storage etc but it does not have an way of clearing the /Var directory.
I have Putty Access to root but do not know which command to use.
I found a few threads but the information is not clear to me as there seems to be an assumption of basic knowledge I don't yet have.
My linux/ubuntu support that usually does this kind of thing for me is away and not contactable and my server is grinding to a halt and unable to store/send email.
I have only a very basic understanding of command line but really need to get this sorted ASAP.

What I am trying to to is set up a cluster as follows:
- There are four nodes
- Nodes three and four have large amounts of storage that will be used for storing user data.
- Nodes one and two will be running a couple of network services.
I'd like have nodes one and two to have a clustered filesystem just between them to store data for the services run only by them.is it possible to share one filesystem between two nodes and another filesystem between two other nodes? The cluster seems to try to make the storage changes across all nodes. They will not be able to spend the extra money to get the same storage in all four nodes. Here is what I have done. I am using CentOS 5.5. After installing CentOS, I did this:
On all nodes:
Code:
[root@node1 ~]# yum groupinstall "Clustering"
[root@node1 ~]# yum groupinstall "Cluster Storage"
[root@node1 ~]# chkconfig ricci on
[code].....
...which I think makes sense because the cluster was supposed to create the PV and the volume group, but did not. I don't even think it tries. The first time it tries to do anything to another node is when I create a logical volume.

I'm trying to find a program that will allow me to run my own server for secure storage. Ideally, this server will allow me to set up separate users. I've heard of solutions that will automatically email the user when a file is placed in their folder, and the email will contain a link with a session ID that expires after a preset time.
Security is a big deal here as well. Something above and beyond SSL would be ideal, like GPG or PGP, so nothing is ever transmitted in plain text.
This would be a server that is accessible from the internet, and would probably be running on a CentOS system.
A vague description, I know. I'm going off of what others have told me they've seen/used in the past. Now I have a boss that wants to use something similar, but trying to find anything that sounds like this has proven quite difficult. I'm hoping someone here knows of something that might work.

We new have server with VmWare ESXi4.1 and we created virtual machine with CentOS5.6.This CentOS5.6 virtual machine will be used as webserver. We need to backup all files and have access to these files. We are going to keep all websites, databases, backups on data storage (NetApp FAS2000 series).
We have two options to how to use this storage:
1: We can mount storage volume directly to CentOS5.6 by NFS.
2: We can add storage via NFS to VmWare and then add new virtual disks to CentOS5.6 by VmWare vSphere client.
What option would you recommend to use? Which option is better, faster and more secure? My thoughts:If we mount storage volume directly to CentOS5.6 so we can access .snapshot directory there is all snapshots. So it's easy to access all backed up files. NetApp has snapshot system and we can schedule to make snapshots automatically, so we don't need to setup any additional backup utilities in CentOS5.6. But we don't have any NetApp snapshot restoring software license so copy/paste from .snapshot directory is only option.
If we add storage to VmWare firstly (by NFS) and then add new virtual hard disks to CentOS5.6 by VmWare vSphere client so we have to setup rsnapshot(or any similar utility) to make backups in CentOS5.6. But NetApp will also make backups of .vmdk files. So it's like double backups, lol :) If storage crashes so we screwed in both ways, I think.

While building my new server I grinded ta hold shortly after inserting the FDR10 DVD.
Hardware:
Chenbro es34069
Albatron KI690-AM2
AMD Athlon X2 64 4850E
IDE 2.5" HD (master)
IDE Slimline DVD (slave)
4x SATA II swap (still empty)
It stops at the message "net: Registered protocol family 2" but in one of my desperate attempts I changed almost every setting in my BIOS (updated to 1.07) and all of a sudden it passed on. Stupid enough I figured it would be a small effort to find the setting and figure out the problem, so I changed them one at a time after loading the defaults....

I have 50 identical workstations that are being dropped shipped from the vendor directly to the remote locations. I need to install a identical configuration, including installed packages, scripts and customize configuration onto each of this workstations. I cannot set up a kickstart server to install from remotely because of my organizations security policies. Not to mention that it would be painfully slow. I thought about DD-ing my "Master" build and sending it to the remote sites, but some of the admins are not very Linux savvy. I would really like to build a bootable DVD that would install the cloned Master build from my server to theirs. I was looking for something that would look like Anaconda to the person installing the image. If I could get them through this base install I think it would be easy to document how to change the workstation unique parameters or value. How to accomplished this? BTW, this will be a RHEL 5.3 server install.

My Goal: I'm migrating data from the OpenSUSE server to the 2008 Storage Server. The idea is that all the data will reside on the 2008 Storage Server in an NFS share which will be mounted to the OpenSUSE server in the same location in which the data sat in initially.
I'd like this to be completely transparent to everyday use -- all programs designed to interact from a few other servers / computers will still work without modification, and, more importantly, all file permissions can remain the same. As far as I've seen the SMB mounting doesn't full preserve the *nix file permissions. I'm hoping the NFS mount will, but please tell me if I'm wrong. SMB is so much more straight-forward and already working. I should also note speed is a giant plus for NFS.
The Players:
Windows Server 2003 - The Active Directory server
Windows Storage Server 2008 - The new file server
OpenSUSE 10.3 - The workhorse server
I have no control over the operating system choice. I have no control over the AD server. I have limited, intermittent access to the person who does have full control of the AD server. I have full control over the file server and the workhorse server.
What I've done: The Storage Server is running Services for Network File System (NFS). It has a 6.5ish TB RAID partition configured for NFS and Samba/CIFS sharing which is used for the data storage. The Samba/CIFS share is mountable and accessible, but I haven't found a way to maintain proper user permissions on the files. When I connect the owner and group for every file is root:root, which led me to NFS in hopes this would fix the problem.
The AD server admin has installed Services for Unix, and we imported the OpenSUSE passwd and group file. Either this didn't work, or it take a bit more configuration. Tomorrow morning we're going to take a deeper look into the SFU configuration with the AD.
Right now I can mount the NFS share on the OpenSUSE under the root account:
Command results truncated to what I think is relevant info. Ask if you need more.
Code:
My Problems:
I'm hoping the "Permission denied" error is solely because the UID and GID mappings are incorrect. I have, however, tried to create an NFS share with full permissions to "Everyone" and anonymous access, and I get the same results.
Also I've run into another roadblock. Why do non-root accounts fail to execute the mount /mnt/datadir command?
Code:
AFAIK 1048 is not a restricted port, so regular users should have access to bind to the port. I also have a Gentoo machine where regular users are allowed to execute the command. The 'mount' command shows that the NFS share was mounted with the username executing the command too.
Server NFS Config:
Code:
The following are the settings on localhost
The above was written yesterday and not posted in hopes I could solve the problem this morning. I failed.
Update: The domain admin installed an NIS server on the AD server. I installed an NIS server on a Gentoo Linux box. They weren't able to communicate. The Linux box thought the Windows NIS service wasn't running and Windows couldn't find the Linux machine. NIS led to a dead-end right about there. I also tried to manually link the user accounts to UNIX UIDs via the AD user properties window to no avail.
