I've been using WHS for over a year now, having first built a WHS server for my parents, before building one for myself. The first benefit of WHS for me has been the automated backup of PCs joined to the server. Shortly after I built my server, the hard drive in my old Vista x64 box gave up the ghost completely. All it took to get it back was putting in a ...

You can run dd on the running disk. Doing so when there are heavy changes to the disk structure should be avoided. Also you should fschk the destination once you are done. The quieter the system is during the backup the better. Running a cold backup (file system unmounted) is the best option if you want to use `dd'. There are better options for backing ...

It is technically possible (as in "shooting-yourself-in-the-foot"), but highly unadvisable, especially if any of the disk's partitions are writable. Picture this scenario: dd starts reading the disk at the start, and merrily makes its way towards the end. When it's halfway there, the OS writes a file to the disk. The file is somewhat fragmented though - ...

I have been using WHS for over a year now and I really like this product. I use it as a media server to store all of my movies, music, and pictures. I have several Xbox 360s that I connect to my WHS to view and listen to all of my media content. The built-in backup feature of WHS is also quite handy as I've had to restore files on several computers. I ...

I managed to do it with diskpart. What I was missing is the command to create a new partition. So here is a run-down of all the commands I used, step by step. I assume you know how to get to the Run prompt since you have arrived at SU. But if not, just press and hold down the Windows key on your keyboard. While still holding the Windows key, press the R ...

I'm running WHS specifically for the automatic backup. I haven't seen another solution that is smart enough to back up files once that exist on multiple machines. I have a 1TB drive backing up six computers, which is pretty near capacity so I'm not able to do much in the way of shared files, but it's easier to remember that shared documents are on the server ...

OpenFiler is a great product, but I would highly not recommend it for the average home user. It isn't going to work how you expect, it will require much more configuration and it doesn't support "home" user features. It is made to be an enterprise level NAS -- that's all. FreeNAS is easier to configure than OpenFiler. If all you really want is NAS, I say go ...

Login to your FreeNas Machine and open the Terminal enter: mount -o rw / when done enter mount -o ro /

I have a server using md for a software RAID5, which I have grown multiple times in the past. It's a pretty simple process. First, we add our new device to the raid array. /dev/sdX is the device you want to add to the RAID group. sudo mdadm /dev/md0 --add /dev/sdX And now we resize the array. N should be the number of devices in the group (including the ...

For two disks, you want mirror mode. This will cause the drives to be exact images of each other. If ZFS tries to read a block of data from the drive and it fails verification, then ZFS will automatically try to repair it. If the repair fails, it'll read it from the other drive and mark the bad drive as failed. You should get a notification that a drive ...

As of yet, there isn't a way to convert zpool structures. Also, there isn't a way to expand a RAIDz. To my knowledge, RAIDz is something you have to setup from the start. That said, there is an exception. If you have three disks in a RAIDz configuration, basically one disk is used for redundancy. You can concatenate zpools so you can create a second ...

Perhaps this isn't an answer to your question directly, but my own experience has been that typical NAS hardware costs about the same as a regular PC. The only reason you might get NAS vs a PC is its lower physical profile. We evaluated the NAS vs PC question quite a bit and eventually ended up with PC, because it has significantly more flexibility for us. ...

An iSCSI target is presented to a host as a local disk. It is not suitable for sharing the same volume across multiple computers. You'll want SAMBA or NFS for this.

FreeBSD and OpenSolaris seem to be the best choices for hosting ZFS With OpenSolaris, ZFS is usually versions/features/bug-fixes ahead. OpenSolaris' hardware support is nowhere near as good as e.g. Ubuntu Hardware support is getting much better with recent OpenSolaris builds but as long as your hardware is supported that shouldn't really matter. ...

A decent workaround that I've been using is to change the disk cache in utorrent. Go to Preferences->Advanced->Disk Cache and check Override automatic cache size and specify the size manually (MB): Set the value according to how much ram you can spare/want to use. I've set mine to 300 and it's considerably lowered the disk overload issues I'm ...

Before you get to converting sync writes to async writes, you have a lot more problems to overcome: If this is a gaming system, how are you going to make sure that your VM doesn't crash in your intense gaming session? How are you going to make this VM visible on the network? Will your drive be able to take the abuse of a mongo 4TB virtual hard disk? (ZFS ...

You specifically mentioned FreeNAS and you have ZFS available to you. I'd use RAID-Z and you will get the advantages of ZFS. This is what I'm doing for a development test server with 3 x 3TB drives sliced up with iSCSI. You can look over an example with some nice screenshots at Building ZFS Based Network Attached Storage Using FreeNAS 8 which is a nice ...

Share the drive in Windows over your home network. Right-click -> Properties -> Sharing -> Advanced Sharing. Nothing could possibly be simpler.

Are those speeds typical? I feel like I should be getting like 100MB/s average. You didn't specify how many drives you have, other than 1TB (SATA3). You could theoretically get some more.. juice by doing RAID10 (4 drives; 2 pairs mirrored and then both pairs striped). That alone (no real configuration tweaks) might squeeze out a better reads for all ...

The sledgehammer solution to this sort of problem is to make the directory immutable. This should be done with extreme care, as it's not a very common operation, so if you do it it's a very good idea to leave a file behind in the directory, with a giant warning: # /some/directory/VAR_HAS_BEEN_MADE_IMMUTABLE.WARNING Once you've done that: # chflags schg ...

CPU should not be a bottleneck unless you have set SHA256 checksumming on your filesystems (or gzip compression). Start by running "top -SH" and "gstat". First one will show you where CPU spends time and gstat will show you what your disks are doing. This should let you narrow down what bottlenecks your performance -- CPU or disks. With RAIDZ your ...

Following @Roland Smith's suggestion, I created a portsjail on my FreeNAS. I gave the portsjail a static IP address, disabled VIMAGE and set the default gateway. I then went into the FreeNAS web-based shell and did the following: Type jls, note the number of the jail and then type jexec [number] sh. Once in the jail type pkg install cups hplip py27-cups. ...

According to the manual on asus.com the board has "wakeup on PCI" and "wakeup on PCIE". Enable these for WOL. You may also need to enable WOL in your OS. It might be disabled by default, but I don't know FreeNAS (nor FreeBSD) good enough to tell you how to. Update: The networking chip is connected to PCI or PCIe Bus, and can thus wake up the system ...

When I last looked (about a year ago), it only supported Time Machine via a lot of hard work - mainly on the side of the Mac in order to tell it to use the Freenas box as a target. Freenas supports AFP and if things have improved in OSX in this regard, it should work fine. For Windows, once you have set up Samba shares, it just works and works very well. ...

A possibile solution is unison: it could be used to syncornize stuff in different directions. It is able to detect conflict and will ask for manual fixes. It works on ssh connection, so it is secure, and you can mix operating systems too (I used form linux, macosx and windows) and saved my days. For more information see also my small blog review.

You should never create an image of a mounted partition. No matter if you booted from it or not. But you'll have a hard time trying to unmount the partition you booted from.

SheevaPlug is an ARM processor based product, whereas FreeNAS is only available for x86 and x64 processors. Having said that, freenas is ultimately a collection of software that allows file and disk volume sharing across a network. From your description, Samba (file sharing via CIFS - like a Windows share) and/or NFS (linux sharing) would suit your needs, ...

Can I assume that since the mainboard supports 48-bit LBA the BIOS will also allow drives over 2.2TB? Yes. Unless you need petabytes of space, you need not worry.

Sorry to have to pull the familiar "it depends", but in this case it really does. What hardware do you have, what will the NAS be used for, what features matter to you, etc. Having a virtual NAS can be both a very good idea and a very bad idea. That said, some thoughts: The traditional weakness of virtualisation is disk IO when running from virtual disks. ...

What is really important is any changes. If those values increase then you have problems. If they remain stable then, while not ideal, the situation is probably acceptable - assuming of course you have working backups.
