Ubuntu Servers :: Media Storage Shared Between HTPC
Jan 14, 2010
I'm planning on setting up a home file server. I was wondering what platform would be recommended for something like this. The server would be used mainly for media storage which would be shared between an HTPC and a couple desktops and laptops. I was thinking of just getting whatever motherboard had the most SATA headers on it (which currently seems to be something P55-based) and setting up a RAID5 fakeraid with some 1.5 or 2TB drives and the OS in RAID1 with whatever drives I have laying around. It there anything flawed with this approach? P55 boards with 10 SATA headers are currently upwards of $200, which is kind of pricey. Is there a more economical route that I should consider? Also, are there any known problems with setting up a fakeraid like this using certain motherboard's SATA controllers?

So recently I've been trying out openSUSE, along with a few other distros, for use on my HTPC. Previously, I'd been using a hackintosh build, so my external media storage HDDs are all formated HFS+. It was actually surprisingly easy to get openSUSE to mount them for both reading and writing.
Only thing is, XBMC has been pretty unstable on all of the linux distros I've tried, and I'm wondering to what degree the HFS filesystem might be affecting things? It would take a fair bit of juggling -- or going out and buying a new multi-TB HDD -- to clear out the disks in turn so as to reformat them with an ext filesystem, but if that would help me get a more stable HTPC with opensuse -- the linux distro I've settled on -- it'd be worth it. I'll paste a link to the log from an xbmc crash, in case that would be helpful, but really, I'm just curious, since I don't really know all that much about how different filesystems work or anything, how much extra strain does the filesystem translating entail?

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'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 used to have three partitions: Win7, Fedora 12 and a NTFS-Storage-Partition.Now I had to reinstall Win7, it doesn't see any files on the storage partition;Windows shows the whole rest of the disk including the linux partition as one drive with 7gb of 80gb free, I can also open it but then there is nothing in it.Linux is still working and everything on the storage partition is still there and accessible in linux.any suggestions? do i have to tell windows the partitions or does it have to do a scan or something?

I have a server running CentOS 5.5 with KVM capabilities. I need to migrate all the VMs to another server with the exact same hardware specs. The problem is it is running on individual harddisks, not shared storage. What is the best way to migrate to minimise downtime?

Let's say a guy wanted to construct a time capsule. I'm referring to one of those boxes or containers that you drop in the ground, and decades later you (or someone else) digs it up to learn things from that time. And let's say you wanted to drop several Gigabytes worth of digital data in that capsule. What kind of storage media would you put it on? CD-ROM? DVD-ROM? USB stick? SATA drive? Magnetic Tape?

Ive been asked to investigate presenting the same SAN LUN to two or more RHEL5 hosts. The hosts are providing independent applications so theyre not clusters from an application perspective. The shared storage location would be used as a common area for imports/exports. Were hoping to reduce file transfer times between the hosts by eliminating the need to copy the files between two storage locations. Some of our hosts run Advanced Server and some are standard. Is there a file system that I can use that will allow multi-host access without running advanced server with clustering services on all hosts?

I need a cluster-safe filesystem for a SAN shared storage in Slackware. Red Hat's GFS is the best/only solution?Given GFS support in a custom kernel, what about tools (mkfs,mount...)?

I built a CentOS 5 Linux cluster with GFS storage using local RAID volume and share it with gnbd_export/import on two web-servers. Now I need to expand that storage to another servers local volume. I saw the picture in the manual, but I don`t know, how can I create that scheme.
I can use gnbd_export on the second server and gnbd_import on the first. In that case I will have two volumes on the first storage and I can expand volume group, logical volume, etc on it.

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 am working on the beginning of implementing a two-node cluster with shared storage (GFS) and IP address. Both machines are virtual on VMware ESX 3.5, that should not make a difference, but that is the background.current status is that I have a single node cluster built with only the IP address configured within the cluster. The issue that I am having is that I have configured a service to contain only the IP address resource, however, when I go into cluster management that "service" does not register. As such, I cannot bring it online, ping it, etc. below is my cluster.conf configuration:
<?xml version="1.0"?>
<cluster alias="tmbackup" config_version="10" name="tmbackup">
<quorumd device="/dev/sdb1" interval="1" min_score="3" tko="10" votes="3">
[code]....

I made the bootable stick with the liveusb creator at https://fedorahosted.org/liveusb-creator/ using an iso image of f10 live cd, a flash drive with 2 Gb capacity and a paersistent storage setting of 200 Mb
I changed root=XXXXXXXXXXXXXXi-do-not-remember-XXXXXXXXXXXX to
On the flash drive to make it bootable
I installed gparted on live operating system and when i rebooted gparted was not installed.

What is the current state of NFS failover (i.e. setting up two server with shared storage, with automatic failover if one fails?) I've seen a cookbook, but no details that would let me assess how well it works. There are lots of complex issues with data consistency, but the detailed information on that is years old. Our needs are fairly simple: 2 servers, a shared array, and I'm reasonably sure that we don't use locking. However we'd like failover to work reliably without loss of data.

I try to set up a 5 nodes cluster and a shared Coraid Storage with conga but it fails with "Shared Storage Support" checked.The message is:'A problem occurred when installing packages: Packages of set "Clustered Storage" are not present in available repository' and it is shown under every node on the next sceen after I submit.The pc where conga runs is on the same subnet (192.168.xxx.xxx) and it has the same /etc/hosts of the other nodes.In that pc runs a proxy too and the nodes go out through it (that pc has 2 NICs)Every node (2.6.18-128.1.14.el5-xen-x86_64) is patched whith the last yum update (this morning) the same is for the pc (2.6.18-128.1.14.el5).Every node has 4 NICs , 2 NICc towards the storage the others in bonding towards the WAN.Every node is exactly alike, they have been installed with the ks.cfg generated from the first node and they all have the support for Clustering, Virtualization, and Clustered Storage.

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.

My 11.04 installation is running beautifully in VM on ESXi. I'm trying to add storage so I added the disks, assigned them in vmware to the vm, then tried to mount them when I received the error code...
my setup:
HP Microserver, booting vmware from USB drive. Hardware RAID card (Adaptec RAID 2405), 2 x 250GB HDD in RAID1 (datastore1) with VM's, 2 x 2TB HDD in RAID1 (datastore2) - the storage I'm trying to add.
A search of the above errors yielded many results, all of them were different scenarios to mine.

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 have collected a number of computers over the years, and now I would like to put them to good use. I considered UEC, but many do not support hardware virtualization and all I really need is storage. Over all the machines, I estimate that I have 4-5 terabytes of storage, all going to waste because each one has relatively low storage space. Is there any way I could setup a redundant storage solution that utilities these machines in a networked system?

I run Debian on my old computer to use it as a server. Everything is configured properly so that it functions as a web server. Now that summer comes closer I will not be home most of the time and I was thinking to use part of my server to upload/download files. Is there some nice package that provides an easy interface for such a task? I am reffering to something like the wikimedia package but for just downloading/uploading files.

I'm trying to delete directories (long story, Mac temp files there, Windows not cooperating) on a sever connected to a HP 20 Modular Smart Array set up as RAID5. System currently running Windows. I've booted from a 9.10 LiveCD but can't see the external drives. Is it correct that I need to install mdadm to "see" those drives from LiveCD? From a different machine (linux) I can mount the drive using samba like so:
sudo smbmount //IP address/hostname RAID5 Root Share /mnt/ntserver -o username=smith,password=abcde123
I have admin privileges on the Windows OS. In linux (or Windows beforehand), is it possible to take ownership of the directories so that I can do a rm -f -r <dir> ?

Can ANYONE point me in the right direction on how to use storage on multiple servers as a single cluster?I thought storage cluster was for that but, after much googling, and even more help from here, I don't think that achieves my goal. My goal is to have multiple servers share a file system, to act as somewhat of a network raid, so if node-A goes down the files are available on other nodes, and hopefully so when the capacity of the nodes are reached I can add nodes to expand the "cluster".
