Ubuntu Servers :: On Building Home Data Storage Server?
Jan 18, 2010
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 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'm looking at building a small NAS setup for my home to hold all my media (DVD's, pictures, music etc..). I'm not too concerned with backups of it at this point as I have all the data elsewhere as it is, but would like one central spot to access it.
A friend of mine turned me on to Ubuntu to do this with but he's never tried it, so I'm looking to see if anyone else has done this or if there issues with it. I've used linux off and on for several years, but this would be my first Ubuntu install.
I'm looking at either using some older hardware I have sitting around, or something cheap like a small dell server (T310 or something). I'd get 4 2TB drives and just use them in a software raid 5 array. It would be accessed with a few different samba shares I'm thinking.

i want to run a homeserver here for centralized data storage and more...features required:
client compatibility with most Linux distributions, MS Windows 2000, XP, Vista, 7, XBOX!
harddisk shutdown if not in use (got some real noisy ones)
easy administration?! (maybe web-based?)
security! no files or folders over the internet (yet)

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

I have an Acer Altos EasyStore SATA NAS box that hung, the only way to reboot was to crash the system (unplug it). Upon reboot it was not recognising the hard drives (it wanted to do a destructive reinitialize). Most of the importent data was backed up, however some was overlooked and we'd quite like to get it back. Removing the disks and placing them in a PC with enough SATA bays to cope, and booting with a live linux distribution (System Rescue CD) I can see the 4 drives are not suffering hardware error and that the original partions exist. Using mdadm I can assemble the Arrays without error (seems to be three but the only one I am concerned with is the RAID5 array of about 3TB). /dev/m1p2 mounts as a loopdevice once an offset is entered. In turn this mounts as an XFS parition. However despite df showing the partition almost to be full. ls -l or ls -a on the mount point shows it to be empty!
I got thusfar using a translation from a German language forum, unfortunately I only speak a little German, and the only other English language post on a simlilar matter I found within that site had no replies. The next step was to unmount loop, then run xfs_chack and xfs_repair on the file system. xfs_check returns that there is are a few dir size and offset errors along with link count mismatches. This I would presume normal for a file system that has become slightly corrupted. xfs_repair (version 3.0.3) gets as far as Phase 3 it finds and corrects zerolength entries, offsets on directories and bogus inode numbers. However the final two lines are:
Code:
realloc failed in blkent_append (2671166480 bytes)
zsh: segmentation fault xfs_repair /dev/loop1
A search on the error missing out data size just returns code to generate it, is anybody able to explain what it means? Also remounting hard drive, ls and varients of still do not return anything. Am I missing some thing (root I am logged in with now would have different credentials presumably to root on the NAS box, so how do I get around this)?

we have purchased the Dell PowerVault NF 500 NAS Storage Box with Window Storage server 2003 is Installed.we have LDAP server for authentication the user in network for accessing network resources.All ubuntu users on client side use ubuntu(LDAP server )for user authentication.when a user logon on client side machine his home directory is created on client machine .
but we want to use the NAS storage device to store the home directories of user.we want to implement that ,whenever a user logon his home directory is created on powerValut NF 500 storage device so that all user data is stored centrally for taking the backup .we want to mount NAS storage device so that user uses when they login and create user profile.

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:

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

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).

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.

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.

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 am going to install Oracle RAC on two Servers, With shared SAN storage (Servers and Storage is IBM) OS = RHEL 5u5 x64 bit
And we used multipathing mechanism and created multipathing devices. i.e. /dev/mapper/mpath1. Then I created raw device /dev/raw/raw1 of this /dev/mapper/mpath1 Block device as per pre-reqs for Oracle Cluster. Every thing looks good, But we faced the performance issue as under.
when we run command :
#dd if=/dev/zero of=/dev/mapper/mpath1 bs=1024 count=1000
the writing rate is approx. 34 MB/s
But If we run command
#dd if=/dev/zero of=/dev/raw/raw1 bs=1024 count=1000
the writing rate is very slow like 253 KB/s

I don't care so much the practicality and needlessness of actually setting up a computer for proxy server for personal usage, but none-the-less, i want to do it, and i'm just wondering about hardware.The proxy, i don't intend on having a desktop environment, so it'll be a terminal interface.But for a system that will handle traffic for 3 pc's and a ps3, how much hardware would one suggest i need, as far as RAM, HDD space, so on and so forth.
I was thinking it would be fun to do with with my old amd k6-2 processor and it's 32mb of ram, but in order for that pc to work, i'll need to replace a few hardware pieces, and before i dumb money into it and pull it out of the closet, i want to find out if it would even be worth my time to do it.

I'm now having to access a lot of data on a portable hard drive on a regular basis. The drive needs to be used with three different Windows systems, three Ubuntu machines and two slackware units. The data is backed up once per week.
I have been using Ext2IFS to access the data (stored on Ext3) from Windows but keep having problems. Obviously Ubuntu and Slack have no trouble reading or writing to the drive. Additionally, some sensitive data will be put onto the drive shortly and I would like to encrypt it.
What is the best solution here? Is NTFS reliable enough and is data access and writing reliable enough from Linux? Can I encrypt NTFS and still leave it accessible by Linux? What is the best software to encrypt the drive with (if I can) that is accessible by both Windows and Linux?

I currently have a 2TB qnap nas which will be relegated to mirroring important files from my new nas. I am building up a HP Microserver with 2*2TB and want to look at the best way to manage the data, disks and backups.
My wish list: Power down unused drives
I want all the disks to appear as one.
I want to be able to easily add an extra drive and add to the available space
I want to be able to replace a disk with a larger one and add to the available space (It's ok if I have to manually copy the data from the old drive to the new drive)
If a disk dies I want the remaining disks to still function with whatever data they have left on them.
Email me if a drive dies
If the server blows up then I can plug any drive from the server into another pc and copy the available data off the disk
Mhddfs - anyone use this much? What's the speed like? Do individual drives get spun down if not used? How is it decided which drive gets the data? No one talks about mhddfs much. It all seems to be about mdadm and raid and LVM which I don't think is suitable for my current purpose. I have a existing qnap nas with a total of 2tb that will rsync changed files from the server nightly. To restore missing files would I use rsync in reverse?

I and setting up a home web server using Ubuntu 10.04 server (local only). I am currently using Webmin 1.53 to access it remotely all is going great very easy to use. Webmin - Check, ftps-fileZilla - Check, Apache -It Works BUT I cant seam to set up Apache as a named server using Bind DSN. Tried most of the help in the fourms and ..... I think my problems is in the master server selection, do i have to use [URL]... or can i just use myservername. I have tryed both with no luck. First time with the server addition.

I would like to have my USB stoage devices to be mounted under my $HOME automatically when I insert them. Those devices have been partitioned, formated with XFS and also given a UUID for this purpose. I think I should use udev's rules and have also done some attempts like this one:
SUBSYSTEM=="usb", ENV{ID_FS_UUID}=="c195a25a-c03e-4cd8-9d86-9b9219acfeb4", OWNER="uqbar", GROUP="uqbar", RUN+="/bin/mount /dev/%k /home/uqbar/work"
Of course it doesn't work. I'm running Kubuntu 9.10 and Ubuntu 9.04 and would prefer a solution not tied to a specific desktop.

I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.
I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?

So I've decided to buy or build a server / NAS.
It's purposes are as follows:
- NAS
- Apache
- Webdavs
- Samba
- NFS
- Time Machine
- PXE-boot server
- DHCP server
- Nameserver
- Router
- Usenet
- Torrents
- Future home automation (with a Velleman USB card).
For hardware, my considerations are the following:
- 2 Gigabit LAN ports: obviously they have to work in Linux,
one is going to connect to the ADSL modem, the other to a Linksys WRT320N router and AP
- 4 harddisk bays (I'm starting with 3x2TB, but I'd like it to be future proof)
- Very low energy consumption
- Not unnecesarily expensive
So I can do two things: build my own system based on an Atom board (but I can't seem to find the right hardware), or buy a NAS that you can install linux on.I've been looking at something like the QNAP TS-410 Turbo NAS. But does anyone know whether you can install your own OS on it? Apparently it comes with a custom linux OS, so am I right to assume that all hardware should work in Ubuntu?

Currently I use FreeNAS, which is a FreeBSD-based NAS distribution for my home server. However, I would like to move to a Linux-based home server with the ability for new software packages to be installed, which is a problem with FreeNAS. I use Lucid beta on my Dell Mini 10v, and have two Windows 7 and one Windows XP desktop(s), with all of them connected via Gigabit ethernet and Wifi N.
The home server would act as a file server (SMB and whatever the best one is for my Ubuntu netbook), a media server (UPnP, MT-DAAPD/iTunes and DLNA for my PS3), as a webserver and as a VirtualBox server just to experiment with. The server itself has a 160GB PATA drive which will be for the OS, and a 1TB SATA drive to be for the data; Gigabit ethernet; an AMD Athlon 64 2.2GHz (with AMD-V) and 1GB RAM.Are there any things you would recommend for me to install? I think that having a window manager would be nice, even if just for initial setup since I am not very experienced with command-line Linux. I'm planning on installing Webmin and a VNC/SSH server so I can configure it remotely. I don't need any firewall or VPN services as these will be provided by a pfSense box separate from this.

I have a fairly large home partition,and several directories with content in, that currently reside in my home account.I now have two slackware installs and would like the content to be available to both installs.Is it OK/advisable to make a directory in /home that has the content in, that both user accounts are mapped to for the content (music and video mainly)? I was thinking of setting the folder as readable/writable by all. This bit makes me wonder if I might encounter problems.There is no spare partition or alternative drive that I could use for this purpose and there is too much data for me to duplicate it in both user accounts.

I've been running my Dell SC440 as a home server/workstation for about a year now and whilst it can cope with both roles, it is power hungry, loud and does get a little slow down sometimes. What I am looking to do is create a home server to take away the need of it to be on 24x7.My requirements in a home server would include:
- Media Server (using TwonkyMedia or uShare)
- NZB Downloader (hellaNZB or sabNZB)
- AFP + NFS file serving
- rsync/unison for Linux backups and N900 media sync and backup
- Email/Calendar/Contacts hosting and sync (zimbra or zarafa?)
I would like to achieve this with an Acer Revo and a couple of 1 or 1.5TB external hard disks, I'm unsure if the Atom processor would be strong enough for all of these services, although I could test it using my netbook, if that can cope, the Revo would be able to easily.

I am running a dual boot system with Win7 on /dev/sda and Ubuntu 10.10 on /dev/sdb
I also have a 250 GB disk I use for storing backup data, /dev/sdc
The two logical partitions on /dev/sdc (/dev/sdc2 and /dev/sdc5) each take up 2.86 GB and I would like to free up that space if possible.
Since the filesystem on /dev/sdc doesn't have an OS on it, does it still require that those two logical partitions exist?
