General :: Filesystem To Choose For NAS Box Based On OpenFiler
Feb 23, 2010
I'm a photographer and I have a requirement find a better method of storing my photos other than multiple USB2 drives via USB hubs. Currently I use a Macbook Pro and 6 external drives connected via USB2 or FW800. 3 are a copy of the first three, kept up to day manually by running an rsync backup. I'd like to run a FreeNAS or OpenFiler NAS box using 2TB drives mirrored via software RAID. But - I would like to have the flexibility of also plugging into the drive physically for the faster throughput when necessary. My question is, is there a file system that both *nix and Mac OSX will play nice with?
I have an application which uses 256k as blocksize. And I would like to have a filesystem which handles I/O blocksize as near as possible to this blocksize.
I can not use EXT3, because that will be to small blocks. I was getting into problem to use XFS; because that has some dependencies to the PAGESIZE in the kernel, it can not use bigger blocksizes than the PAGESIZE in the kernel.
What more opertunities do I have? Or how can I get XFS to work with bigger blocks.?
I downloaded the lastest x86 stable release of openfiler and installed it on VBOX durring the install I selected to manually do the partitions and added a
/boot swap (x2 ram) /
Partition scheme. I selected DHCP client on the network configuration. Now from what I understand once I have done that I should be able to point my browser to https:<IP>:446 and login as root and configure everything within the GUI. But when I log in there is nothing to configure. My host system is Ubuntu x86_64 4GB Ram amd dual core processor.
I was extraction some file through command line then I encounter on notification from winrar. This file exist what u want to do replace never quite I don't want that winrar will prompt me to choose action. Everytime whenever this situation occur it will overwrite / skip that file Syntax I am using for unrar rar e -pmypassword filename
what is the best way to go for setting up a NAS. It will be used for 2-3 weeks worth of HD Video storage and needs to have a redundant power supply, swappable SATA drives. I'm thinking of using either FreeNAS or OpenFiler as the OS.
We are limited to a small amount of available server hardware in South America. To buy an 8TB HP NAS server costs $11000, quite pricey for us. In Canada I'd just get a couple of Buffalo Terrastations, but that's not an option now.
So I'm thinking of going with an INTEL SR2400 ($550), maybe even two of those for more redundancy. Anyway, I was thinking of using 1TB or 1.5TB drives, but according to other web sources, that's a bad idea with RAID, as it's more prone to hardware errors.
I notice that on DistroWatch, the descriptions include "debian based", "arch based", etc. For the newbie, is there any practical difference between the different bases, or is it a Coke vs Pepsi type question?
Is a distro based on Debian say, easier for a newbie to learn or work with than say one that is FreeBSD based?
I've been tinkering with both recently to see what can suit my needs as a simple raid1 mirrored backup server. I used FreeNAS for all but minutes before I had a raid1 array running and shares set up through CIFS. Using Ubuntu on my laptop I was able to see them as well. I had some more figuring out to do, as I wanted each share to be blocked off from the other. aka - I didn't want "fred" to be able to access "bob's" share. So then I move on to Openfiler to check it out. I hear it's simpler. It's web interface, while no doubt much slower than FreeNAS, was easy to mingle around. At first glance, I thought I'd like it more.
I began to set up my raid1 array. After realizing the final release I was dealing with had a bug, I found some commands to run in a root shell to fix. Okay, so now we're moving along... raid1 array created. Then I had to create a volume group. Then a volume. Then shares. And I still don't have it running over cifs. I'm curious if FreeNAS by nature is truly simpler to set up raid array's with, or if maybe I'm just totally misunderstanding Openfiler and that be the reason why I'm thinking this.
So what i would like to do is possibly get an atom 330 board with a pci-e slot and a 12port raid card and 2 or more GB of ram.Wondering if this would be a better setup then what i have now.Now there are some fall outs to what is setup now which are that Openfiler can not detect if a drive has failed so it requires me to monitor this server on a regular basis. I considered doing a software raid 6 but wasn't too keen on that since i read it takes a fairly good machine to compute.
I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.
I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage *Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?
I am somewhat new to linux but I am good with computer and can learn fast so difficulty level doesn't really matter I just need an all around good fast nice looking linux distro.Any ideas? Please tell me why I should try that version of linux.
We are starting the development of a project in PHP+MySQL that will become a software-as-a-service.After starting and planning how we would deploy the project, the first thing that came into our mind was: the project will be hosted on our Debian stable server and will contain all of our clients databases and each client folders for the project (and of course, a separate server for backups) and all projects running "under" the same apache and mysql server. This was our preferred approach.
Another friend suggested us -as a second approach for the deployment- that instead of having all projects and all databases running under the same physical server and under the same apache and mysql, that we could build our own "cloud" using something like openQRM and have each one of the projects deployed in a separate "virtualized" server (one virtual server per client) and this way the resources are better balanced and is easier to recover a virtual server if crashed as the backups are made of the virtual servers images. He said that this is a very new concept that is taking the internet services market more and more.
So, we started to research about the "cloud computing" concept in order to have a better idea of this second suggestion our friend gave to us.In terms of performance, it seems to me that the "cloud" approach could consume a lot of moreresources than the first approach ?? and is a lot harder to maintain and extend ??I would really appreciate your opinions and recomendations on which option is really worth for what we are going to offer to our clients.
I'm still to install Linux (waiting for a replacement of a bad DIMM) on my new box. It will probably be CentOS, following 'Rubberman's recommendation in forum/coffee-lounge/166195-distro-recommendation-development-use.html .
I assume (as I haven't installed Linux before) there could be a choice of file systems. Is there any recommendation on what I should/could use ?
The solution should be capable to use intranet only (no communication should traverse the inernet). It would be of an advantage if it would support conferencing. And if it's possible it'd be fine if it'd be free.
One solution which comes to my mind is jabber, but I do not have any experience with it... what's your oppinion on that? What other solutions are there?
I have a list of files that I am copying around for various purposes. What my current command looks similar to this:cat list_of_files | xargs -I {} /bin/cp -f {} /destination/dirI am using the full path to cp so that the default alias of cp -i does not take effect. However, when I find a duplicate file, it is overwriting any that have already been copied. What I would like to do is to force cp to not overwrite and not prompt.
I have a small script that uses the find command to look for a log file named: backup_log.txt. And then uses the first value in the log file as a variable in the script later on. However, say there are two or more of these log files located in different directories, how would I let the user choose which log file will be the one to use, and then make that (fullpathtofile) the value of the variable that will be used.
I got an 8 GB USB Memory stick wich I want to use, I dont want to install Linux on my harddrive, I want it portable and on an USB stick.
What I need is a distribution thats big with lots of programs and the Ability to Save files and configurations Directly on the USB Memory stick, and it should be able to run apache, mysql,php and java.
I want the USB memory stick to act like a harddrive so to speak.
Also, I already downloaded and tried Knoppix Live CD, but I cant get knoppix 6.4.4 to work, but an older version worked. But its so small, not so many programs. Is there a way to install lets say a DVD version of a distro to USB and make it work like the live version?
i have purchased a Lenovo y410 and want to install LINNUX on it configuation intel core 2 duo p7300,ram 2GB hdd 250 .i haave found that download link at ubuntu giving us i386.iso and openSUSE has given a link to i586.iso under 32bit processors .For my hardware confifuration which will b suitable.Is there be any thing related as far as i know p4 has 786 architecture then why they are not providing that in download links kindly help me to which one should i go for
I create a script and when I execute it, a dialog show for me choose one option: Run in Terminal, Display, Cancel and Run. I want run it automatically without choose option.
I've got some source code that loads and plays WAV files through the OSS drivers (and USB audio). The code works even under 2.6.34. Is there any benefit to rewriting the code using the ALSA system?
I'm working with an embedded Linux (Montavista 5.0). I want to allow users of my program to choose filenames with Unicode chars like the German All Unicode chars are visible inside the program (dialogs, buttons,...) and I can write Unicode chars into files and read them. But it is not possible for me to create a file with an Unicode filename! I can't write such Unicode chars in the shell! I set my locals to "de_DE.utf8". locale charmap says UTF-8! But when I try
Every Unicode char is writte to the shell in this way with a leading The same happens when I write such chars from my program to the shell with printf!
I am working on a set up, and I like to be able to toggle compiz on and off, or toggle dualscreen on and off. The thing is, I also have conky on my desktop as well as a terminal window embedded in my desktop (that requires compiz). So, when I turn comiz off, or resize my desktop, I want to be able to reposition conky/embedded-terminal and the terminals position is relative to my conky position and the size of my virtual desktop.
I can do this all fine, except that to reposition the terminal I need to kill it then reopen it. But if I kill gnome-terminal it kills ALL gnome-terminals instead of just my embedded one. How can I specifically close my embedded one and leave any others untouched? Lets say that the title of my embedded terminal is "trans777"Also, the trans777 titled gnome-terminal will be killed when compiz is not running.
i've got UBUNTU 10.10 installed on my laptop.After i turn my laptop on and the comp prepares 2 boot the OS,a screen asking me to choose which OS version i'd like 2 select.Now ideally i'd like jst 2 names on dat list namely-Ubuntu and win xp..But I've a host of other options as well like memory testblahblah'safemode'....wotevr....Is this ok 2 have so many OS startup options.Is there a way to get rid of unwanted stuff like changin the BOOT.ini file or in any other way???
When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.
This is my third SLackware install. I installed 10,12, now 13. the Xorgsetup has changed I think, it does not display the screen to choose Horizontal and Vertical settings for the monitor. In addition, how can I set the Refresh rate?
I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.
