Best NAS for full-fledged Linux?

Now I know this thread's title might be a little ambiguous.
I'm trying to find the best network storage which will allow me to host multiple types of data, like movies, tv shows, etc. and stream it through my LAN, so that it can be accessed with any of my TVs with appropriate hardware (with access to LAN).
The thing is, I'd also like it to be able to download data from Bittorrent and Rapidshare, then unrar them.
That's why I think I need a NAS which will be able to run Linux with a lightweight GUI session to use many programs available on Linux, like JDownloader (will it handle Java?)
I don't even know if drives like these are available. I know about drives like WD My Book which could have such functionality (progams like pyLoad), but AFAIK, they only allow to login to them using ssh, and that's full CLI, as I understand it.
It doesn't need to be NAS, it can also be a router with an external hard drive, I'd just like it to have the functionality as listed above.
I have some basic Linux knowledge, and am not afraid of installing custom software, as long as it's not so hard.
PS: It would be also great to be able to log into it from the Internet, not only inside the LAN.
PPS: I don't know if hardware requirtements are that important, but they'd include:
*) Gigabit Ethrnet preferred, 100Mbits otherwise
*) At least 1 TB of storage
Thanks in advance!

GUI sessions... Excuse me?
A NAS should run SSH, maybe some services with web frontends. A GUI is a waste of RAM and CPU cycles.
I agree with you about the GUI for a NAS.... but the OP also wants to run JDownloader, which requires Java, and I believe, a GUI. I'm looking for the same sort of thing, and the Java and the GUI are where I get stuck.
I do have an NSLU2, but haven't set it up... I don't think it has the horsepower or RAM to do what I want, which means hacking the hardware -- yuck!
The OP may want to consider Marvell's PlugPC platform, which will do much of what he's looking for, minus the Java/JDownloader (I think). It's a nice compact, low-power solution, and there are companies that have taken the platform and added software and hardware to make it a more finished product. I believe the PogoPlug is an example of this, other ones can be found on Marvell's website, or by Googlizing "PlugPC"
An old PC and FreeNAS is another alternative that I've considered. That, or a lightweight version of Linux, would provide the GUI and Java features to run JDownloader for not much more money than a stand-alone NAS. Less, actually, if you have an old PC with Gigabit or 100 Megabit Ethernet available. The downside to this alternative is space and power. An Atom-based one might solve those issues (Asus makes a nice one about the size of an external USB HD for $200), but even that would not have the low low power consumption of a PlugPC or an NSLU2.
I've been playing around with my WD TV and Patriot Box Office Media Players... the WDTV can be hacked to host torrents (the Patriot does it natively) and they can sorta handle fileserving as well. No Java or JDownloader solution, unfortunately... but they are a reasonable stopgap measure for me right now.
The beauty of all these various solutions is that they've largely been enabled by Linux and the FOSS movement. It's truly remarkable what Torvalds started and the community has embraced and extended...
If I come across other solutions I'll report back...

Best practices for Full fledged CQ5 Development environment

Hi All,
I am working on CQ5.5. The following environemnt we areusing for development.
CRXDELite < - > Eclipse Java Content Repository Perspective < - > VLT Check-in/Check out <-> J2EE Perspective <-> SVN
CRXDELite, Eclipse Java Content Repository Perspective ----> component/template creation (mainly jsp coding)
J2EE Perspective ----> Java servlet coding (mainly java coding)
VLT Check-in/Check out ----> For moving the data from/to J2EE Perspsective from/to CRXDELite
SVN -----> Versioning from J2EE Perspective
is there any other possible way for a full fledged development environment using eclipse?
If you are using any other pluging/best prctices kindly let know.
It will be really helpful.
Regards,
Raja R

Hi,
we have a similar setup as the described but uses VLT mostly without CRXDE. Most of our developers uses other tools do develop, such as IDEA/IntelliJ for OSGi development and script development. We have also choosen to use the CQ Blueprint Maven Artifacts (http://www.cqblueprints.com/xwiki/bin/view/Blue+Prints/The+CQ+Project+Maven+Archetype) and separate our different parts of the sites in modules and use Maven to build and deliver packages.
If you are not forced by policies to use SVN, I would advice you to use Git instead.

What is the best practice for full browser video to achieve the highest quality?

I'd like to get your thoughts on the best way to deliver full-browser (scale to the size of the browser window) video. I'm skilled in the creation of the content but learning to make the most out of Flash CS5 and would love to hear what you would suggest.
Most of the tutorials I can find on full browser/scalable video are for earlier versions of Flash; what is the best practice today? Best resolution/format for the video?
If there is an Adobe guide to this I'm happy to eat humble pie if someone can redirect me to it; I'm using CS5 Production Premium.
I like the full screen video effect they have on the "Sounds of pertussis" web-site; this is exactly what I'm trying to create but I'm not sure what is the best way to approach it - any hints/tips you can offer would be great?
Thanks in advance!

Use the little squares over your video to mask the quality. Sounds of Pertussis is not full screen video, but rather full stage. Which is easier to work with since all the controls and other assets stay on screen. You set up your html file to allow full screen. Then bring in your video (netstream or flvPlayback component) and scale that to the full size of your stage (since in this case it's basically the background) . I made a quickie demo here. (The video is from a cheapo SD consumer camera, so pretty poor quality to start.)
In AS3 is would look something like
import flash.display.Loader;
import flash.net.URLRequest;
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.ui.Mouse;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.display.StageDisplayState;
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
// determine current stage size
var sw:int = int(stage.stageWidth);
var sh:int = int(stage.stageHeight);
// load video
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
var vid:Video = new Video(656, 480); // size off video
this.addChildAt(vid, 0);
vid.attachNetStream(ns);
//path to your video_file
ns.play("content/GS.f4v");
var netClient:Object = new Object();
ns.client = netClient;
// add listener for resizing of the stage so we can scale our assets
stage.addEventListener(Event.RESIZE, resizeHandler);
stage.dispatchEvent(new Event(Event.RESIZE));
function resizeHandler(e:Event = null):void
// determine current stage size
    var sw:int = stage.stageWidth;
    var sh:int = stage.stageHeight;
// scale video size depending on stage size
    vid.width = sw;
    vid.height = sh;
// Don't scale video smaller than certain size
    if (vid.height < 480)
    vid.height = 480;
    if (vid.width < 656)
    vid.width = 656;
// choose the smaller scale property (x or y) and match the other to it so the size is proportional;
    (vid.scaleX > vid.scaleY) ? vid.scaleY = vid.scaleX : vid.scaleX = vid.scaleY;
// add event listener for full screen button
fullScreenStage_mc.buttonMode = true;
fullScreenStage_mc.mouseChildren = false;
fullScreenStage_mc.addEventListener(MouseEvent.CLICK, goFullStage, false, 0, true);
function goFullStage(event:MouseEvent):void
    //vid.fullScreenTakeOver = false; // keeps flvPlayer component from becoming full screen if you use it instead
    if (stage.displayState == StageDisplayState.NORMAL)
        stage.displayState=StageDisplayState.FULL_SCREEN;
    else
        stage.displayState=StageDisplayState.NORMAL;

Best Practice for full motion

I'm new to this whole publishing video to the web thing and
I'm quickly learning that full motion recording is a bit large to
deliver via the web. So I guess I'm asking for advice on how to
show/demonstrate a full motion action in the most efficient manner
possible. When I import the created SWF from Captivate into Flash
8, it becomes blocky (black pixel looking blocks) and does not
export in a usable fashion. I think it's from changing the frame
rate from 30 to 10.
It is possible to record at a lower frame rate for full
motion? If not, then is there a better compression scheme that I
can be using to better deliver the video?
Any help is greatly appreciated. Thank you!

What are the best dimensions to allow for iPad 3 Retina for full-page landscape images?

What are the best dimensions to allow for iPad 3 Retina for full-page landscape images?
I read an article and cannot find it that said something about trying to make it 2million pixels and JPG to keep it small, but what exactly should the dimensions be that I ultimately import? Is there some kind of a "density" setting I have to use, as well, when exporting from Photoshop, for example?

See Optimizing performance in your iBooks Author books
Density is discussed by Apple in this context as 'dpi'...

264 - new iPad
At the top of this forum there are popular links listed on the right, including image sizing etc. Be sure to study those existing/previous threads on this topic.
Good luck.

Best software for doing full backups to ext. hard disk to to be used to restore system

As a new PC owner I wanted to find out what the best software for doing full backups to external hard disk, to to be used to restore the system if primary primary disk crashes. Im aware that Windows, Acronis and Paragon all have software that doing varying degress of back and resore functions.

lasvideo,
My favorites are ShadowProtect to do an "image backup" of boot drive and Beyond Compare for backing up files for all other "data" arrays. ShadowProtect does not seem to have much market share compared with Ghost and Acronis, but I really love it.
What I like about ShadowProtect:
- Extremely fast (complete image backup for 61GB of files on my boot SSD RAID 0 array to a RAID data array takes less than 3 minutes)
- Can do image backups across a LAN; restores from boot CDROM and USB device
- Allows for backups from one controller and restore of OS on a different controller and/or RAID configuration (has HAL tools; Hardware ? Layer I think)
- Can "mount" an image backup as a drive letter and see (and copy) all directories, files, etc. that are contained in the archive
What I like about Beyond Compare:
- Can choose what to backup and what to ignore very easily (for example you can set it to ignore certain files or directory names to ignore and then save how you set things up as a "session")
- Only needs to copy over files that are new or have changed since your last backup
- Makes it very easy to selectively delete files from your backup

Best video format for converting DVD to NAS for widely sharing

Summary: The article shows you with an easy workaround for
copying DVD to NAS for streaming by ripping DVD to NAS friendly video
format on Mac and Windows
I recently purchased a NAS to store all my music/photos etc on. I
can stream stuff to my iPhone/iPad using the NAS software. What I want
to do is rip all my DVDs (over 400) to my NAS, but I’m not sure which
format to do it in, to play nice with my Apple TV2, Xbox 360, iPhone,
iPad etc. I wanna get some advice as to what format to rip in and what
software to use?
Learn some tips from online, I got know that to copy dozens of DVD movies to NAS,
you need to get the content off the DVD disc as a protection-free and
easily readable element for NAS. In this case, at the first place
powerful third-party software for backup DVD to NAS is what you need.
There are many, many DVD ripping tools on the market. I’ve tired a pile of them.
Brorsoft DVD Ripper
is the best one I’ve tried yet. It is capable of ripping DVD to MP4,
AVI, MKV for NAS streaming with no quality loss; it also enables you to
copy DVD main movies for backup onto NAS in .vob format. And what I’ve
learned is that MP4 would be one best target format for it is fully
compatible with nearly all media devices including iPad, iPhone, PS3,
Apple TV, etc. If you are running on Mac OS X, turn to DVD Ripper for Mac. If you haven’t got the software, download it now and let’s start the conversion.
Ripping and copying DVDs to NAS
1. Launch the DVD ripping program for NAS devices . Then
click "Load DVD" to import the DVD files you want to convert. To select
the subtitles you like, simply click Subtitle and select the one you
prefer. P.S. Before start the conversion, you can choose to backup DVD mian movies.
2. Click Format bar and choose your desired format. To store
hundreds of DVD's on NAS, you can rip DVD to .mp4, or .avi, .mkv, etc
compressed format. And click Settings bar, you can adjust the level of
compression to suit the quality you want.
Tip: If you like, you can click “Settings” to change the
video encoder, resolution, frame rate, etc. as you wish. Keep in mind
the file size and video quality is based more on bitrate than resolution
which means bitrate higher results in big file size, and lower visible
quality loss, and vice versa.
3. Press the "Convert" button to start ripping DVD for NAS streaming.
After the conversion, click Open button to find the output files.
Make sure the wireless network connection is accessible among the NAS
and Apple TV, PS3, HD TV or other media players. Then just enjoy the
high quality DVD movies anywhere anytime.

I've always found encoding with Handbrake and choosing the Apple TV2 preset is an excellent place to start and video encoded using that preset will work on my iPhone 4, 4S and iPad 2.
If the files encoded using that preset are too big for one's taste they can always encoded at a lower average bit rate rather than using the default 'Constant Quality' of 20.
Later on I'm sure the Handbrake group will have an AppleTV '3' preset supporting the 1080p format supported by the ATV3 and iPad '3' but using such a preset would not create a file usable on the iPad 2 or the iPhones.

Best method for networking with ubuntu linux

Hi,
I'm setting up an ubuntu linux fileserver, and I was wondering what the best method for filesharing with my mac is. I'm currently running osx 10.4.11, though I may be upgrading to 10.5 soon. I'll be running SMB networking for a couple of other computers, but I'd prefer something a bit more robust that can handle file permissions etc.

Mac OS X supports NSF out of the box. Configuration isn't documented.
I recall Apple got rid of net info manager in Leopard, so the configuration will be different. Perhaps more unix like.
Mac OS X support the Unix Network File System (NFS). However, it leaves out
the GUI.
This page show you how to use NetInfo Manager:
http://mactechnotes.blogspot.com/2005/09/mac-os-x-as-nfs-server.html#c1168221713 40271068
NFS Manager can both setup NFS shares and connect to NFS shares.
http://www.bresink.com/osx/NFSManager.html
Once you figure out how NFS Manager configures the NFS shares, you can
use Applications > Utilities > NetInfo Manager to create more shares.
You will either have to coordinate Unix Userid number and Unix Group Id number or use the mapall option on the share.
To find out your Mac OS X userid and group id do:
applications > utilities > terminal
ls -ln
ls -l
# lists the NFS share on your mac
showmount -e localhost
#list NFS shares on a remote host
showmount -e remote-ip-address
Once you see what NFS Manager does, you will be able to use NetInfo Manager to manage a connection. In Mac OS 10.4 you can configure the /etc/exports control file. See man exports for the details. Before that you had to have the data in NetInfo manager. When Mac OS X came out, many common Unix control files were not present. Instead the data had to be in NetInfo manager. Over time Apple has added more and more standard Unix control files.
======
You do know about the need to match userids & groupids.
# display uid and gid
ls -ln
sudo find / -user short-user-name -exec ls '-l' {} \;
# on Mac OS X
you will need to go into NetInfo Manager and select user and find your short-user-name. Change uid and guid.
#on Linux look in
/etc/passwd
/etc/group
# with care...
# change 1000:20 to your values for uid:gid
sudo find / -user short-user-name -exec chown 1000:20 {} \;
The manual for Tenon MachTen UNIX (which Apple checked when doing Mac OS
X) says that one should crate the file /etc/exports, which will cause
portmap, mountd and nsfd to launch at startup via the /etc/rc file. The
file must not contain any blank lines or comments, and each line has the
syntax
directory -option[, option] hostlist
where 'directory is the pathname of the directory that can be exported,
and 'hostlist' is a space separated list of hostnames that can access the
directory. For example
/usr -ro foo bar
/etc
/Applications
/User/gladys gladys
The client the uses a command like
/sbin/mount -t type [-rw] -o [options] server:directory mount_point
where 'type' is 'nfs', 'server' the name of the server, 'directory' the
server directory mounted, and 'mount_point' the client mount point. See
'man mount' for details.
I haven't tried the above, but it would be nice to know if it works on Mac OS X.
Hans Aberg
This will give you some hints on NFS. Post back your questions.

Outgrowing storage - best NAS/SAN options for OS X Server environment?

Hi All,
We use an Xserve (2x3 GHz Dual-Core Intel Xeon) for our production/graphic design team. I have a 1TB ADM dedicated to "live" jobs and another 1TB ADM for "archived" jobs. (A third, smaller ADM houses OS X Server only...)
Both 1TB drives have a dedicated 1TB external drive for nightly backups and another for weekly backups (we use SuperDuper). This very basic system has worked well for us, but our storage needs are increasing. I'd like to double our current scheme -- just bump the "live" and "archived" environments up to 2TB.
I see a lot of NAS and SAN options. Main concerns for me are:
1) compatibilty with our current Mac OS X Server environment;
2) cost; and
3) ideally, preservation of our clean and simple backup scheme
Wanted to get input from other Xserve/OS X Server users as far as the best options for this transition...
Thanks!

I am a huge fan of the Netgear (formerly ReadyNAS) NAS devices. I've owned 2 of them now, and am now standardized on the little 4-bay NVX Pro. It supports AFP perfectly as well as Time Machine, SMB/CIFS for any windows needs, iSCSI, NFS, RSYNC, etc. etc. iSCSI is a great option not to be under-estimated, though NFS is the more traditional backup model for Network storage. I backup several Apple machines to the single NAS, which is now running 4x3TB drives in the XRAID2 format (essentially RAID5). I can pull a drive in live production and swap it out and the RAID re-syncs without interrupting file transfers, etc. It's also got some nice plugin's of some open source tools like Subsonic server, Wordpress, etc. etc. They make a myriad of devices with the same basic software, just different amount of drive bays, enterprise vs. SMB market, etc. etc. Again, I chose the NVX Pro, but there are other options up and down the line-up. And no, I have no officialiation with Netgear, in fact on a certain level, my company competes with them :-) Lastly, remember, there is value in off-site backups as well, in case of fire, theft, etc. If you're really paranoid, like me, you could additionally mirror your NAS to an off-site NAS or other cloud-based solution. Of course, there's a cost for everything. Good luck with it.

Oracle White Paper- Storage Option for RAC. on Linux

hi..
This in reference with White Paper.. Stotage Option for RAC on LINUX. Author- Umadevi Byrappa.
Which states on page 10: To Use NAS for RAC database file storage select the file system storage option in OUI. or the Clustered file system storage option in DBCA.
With which i disagree. File storage option of oracle 10g RAC only shows.
1. Clustered File system.
2. ASM
3. Raw Devices.
When i try to select Cfs and select the shared directory on NFS it says. < Directory_Name> is not a clustered file system or Shared on Both <Server_1> < Server_2>. and at this point of time i m stuck.
1. I dont want to use OCFS as its not supporting NAS.
2. Selecting CFS doesnt recognise mounted shared volume as valid storage device option can only store OCRfile and CSS file.
3. So, I have to use ASM.. with zero padded files..which i dont want to because no other option. ( PART NO. B10766-02 PAGE C-6)
Also, I would like oracle to provide Back up Recovery Option or Document which tells me how could i Recover Database when i use Zero Padded Files.
What would be the best Option in the above scenario ?
I hope by applying patch or with workaround somehow it shows Filesystem ONLY.I'll be the happiest man in this Case.
Any suggestions and corrections are most welcome. I wish i m wrong.
Nadeem ( [email protected] )

NFS isn't a clustered file system at all - by RFC it is an exported file system with access controls
If your vendor offers an NFS solution over and beyond that - more power to them. However that isn't "NFS"..
http://www.faqs.org/rfcs/rfc3010.html
You can use NFS in a clustered server environment (to mount apps, read only data and for synchronous access to files), however it doesn't support the concurrency out of the box for RDBMS transactions - if a vendor is supporting this promise then that is for you to decide.
However i stand by my statement that NFS is a file system exported across your network and not a full clustered file system.

Networking "best practice" for setting up a farm

Hi all.
We would like to set an OracleVM farm, and I have a question about "best practice" for
configuring the network. Some background:
- The hardware I have is comprised of machines with 4 gig-eth NICs each.
- The storage will be coming primarily from a backend NAS appliance (Netapp, FWIW).
- We have already allocated a separate VLAN for management.
- We would like to have HA capable VMs using OCFS2 (on top of NFS.)
I'm trying to decide between 2 possible configurations. The first would keep physical separation
between the mgt/storage networks and the DomU networks. The second would just trunk
everything together across all 4 NICs, something like:
Config 1:
- eth0 - management/cluster-interconnect
- eth1 - storage
- eth2/eth3 => bond0 - 8021q trunked, bonded interfaces for DomUs
Config 2:
- eth0/1/2/3 => bond0
Do people have experience or recommendation about the best configuration?
I'm attracted to the first option (perhaps naively) because CI/storage would benefit
from dedicated bandwidth and this configuration might also be more secure.
Regards,
Robert.

Option #4 (802.3ad) looks promising, but I don't know if this can be made to work across
separate switches.It can, if your switches support cross-switch trunking. Essentially, 802.3ad (also known as LACP or EtherChannel on Cisco devices) requires your switch to be properly configured to allow trunking across the interfaces used for the bond. I know that the high-end Cisco and Juniper switches do support LACP across multiple switches. In the Cisco world, this is called MEC (Multichassis EtherChannel).
If you're using low-end commodity-grade gear, you'll probably need to use active/passive bonds if you want to span switches. Alternatively, you could use one of the balance algorithms for some bandwitch increase. You'd have to run your own testing to determine which algorithm is best suited for your workload.
The Linux Foundation's Net:Bonding article has some great information on bonding in general, particularly on the various bonding methods for high availability:

What are the best approaches for mapping re-start in OWB?

What are the best approaches for mapping re-start in OWB?
We are using OWB repository 10.2.0.1.0 and OWB client 10.2.0.1.31. The Oracle version is 10 G (10.2.0.3.0). OWB is installed on Linux.
We have number of mappings. We built process flows for mappings as well.
I like to know, what are the best approches to incorportate re-start options in our process. ie a failure of mapping in process flow.
How do we re-cycle failed rows?
Are there any builtin features/best approaches in OWB to implement the above?
Does runtime audit tables help us to build re-start process?
If not, do we need to maintain our own tables (custom) to maintain such data?
How did our forum members handled above situations?
Any idea ?
Thanks in advance.

Hi RI,
How many mappings (range) do you have in a process flows?Several hundreds (100-300 mappings).
If we have three mappings (eg m1, m2, m3) in process flow. What will happen if m2 fails?Suppose mappings connected sequentially (m1 -> m2 -> m3). When m2 fails then processflow is suspended (transition to m3 will not be performed). You should obviate cause of error (modify mapping and redeploy, correct data, etc) and then repeat m2 mapping execution from Workflow monitor - open diagram with processflow, select mapping m2 and click button Expedite, choose option Repeat.
In re-start, will it run m1 again and m2 son on, or will it re-start at row1 of m2?You can specify restart point. "at row1 of m2" - I don't understand what you mean (all mappings run in Set based mode, so in case of error all table updates will rollback,
but there are several exception - for example multiple target tables in mapping without corelated commit, or error in post-mapping - you must carefully analyze results of error).
What will happen if m3 fails?Process is suspended and you can restart execution from m3.
By having without failover and with max.number of errors=0, you achieve re-cycle failed rows to zero (0).This settings guarantee existence only two return result of mapping - SUCCSES or ERROR.
What is the impact, if we have large volume of data?In my opinion for large volume Set based mode is the prefered processing mode of data processing.
With this mode you have full range enterprise features of Oracle database - parallel query, parallel DML, nologging, etc.
