Regarding power supplies, it is important to remember that the hotter they run, the less efficient they become. They also become less efficient over time. I just try to keep in mind if I'm running into really strange computer issues on older hardware (2+ years), memory tests all check out, and a CPU stress test doesn't indicate any problems, the PSU is likely at fault. Buying a cheap PSU for a computer is a really bad idea (no matter the computer in question). You're relying on it to power every part of the PC, if it goes bad, it may impact/damage every component in your build.

I put my swap on an SSD drive I auto mount with mount_drives. It also hosts virtualbox images. Works fine for me. I'm using the swap package available via unMENU.

I copied the mount.cifs from 4.7 to an unRAID 5.0b14 machine I'm managing, and was able to access/copy files from the share. I saved it in /boot and added the following line to my go script: cp /boot/mount.cifs /sbin This may break things as it's probably compiled under a different kernel, at least as far as I can tell. Here be dragons.

Avahi comes with unraid as far as I know.

On my motherboard I had to format the flash drive as FAT and not FAT32, as (for whatever reason) the system refused to boot from a FAT32 drive. I confirmed this with a couple other FAT32 USB drives I boot from for PC recovery that I know work. I believe the HP utility allows you to format the drive as FAT.

Thanks HAVOC, I wasn't aware of that page's existence. Good to know.

Install unMENU, and then go to Package Manager, and select, then install, then choose reinstall on reboot. Instructions for installing unMENU are here: http://lime-technology.com/forum/index.php?topic=2595.0. You won't need to remove your flash drive to do this. I'd plug the USB port into your unRAID box. You can always make backups of your Windows box to unRAID, but probably not the other way as I assume your unRAID box houses more information than your Windows can hold. As far as I know there isn't a way to share the USB connection from a UPS to signal shutdown on multiple machines.

I've purchased 2 of these for unRAID (one for me, and one for a friend). They are solid cases, but there were some quality issues, in my opinion: my case came with a dented side panel, but the box was damaged so this probably happened in shipping one of the drive caddys was bent in such a way it wouldn't click into the rails properly the fan contoller for both had to be bent to fit into the expansion slot the fan controller, when mounted into the non-motherboard expansion slot is difficult to access the bracket that mounts the 2 fans at the front is not as easy to remove, put back as it could be the manual is so sparse it's not very useful the fans are pretty anaemic - but as my drives are spun down most of the time this isn't a huge concern for me. I'd probably have to replace them if my unRAID box was doing more stuff I wish there were more spots (under the motherboard ideally) for zip tie, tie offs. I had to buy extension cables for the PSU, and would like to snake the cables back and forth to use up the excess slack All in all, I'm pretty happy with the case, just something new buyers should be aware of.

I don't think the LSI controllers are supported by 5.0b14, but are supported by 5.0b12. Just something you'll need to be aware of when installing.

Can you plug the usb drive into your PC and copy the file locally? Also have you tried re-downloading the key?

Attaching a syslog to this will help anyone who can assist diagnose the problem. You may want to try refreshing the web page manually.

What specific steps are you using to shutdown? I generally take my array offline before rebooting/shutting down. Do you have any apps running on a drive that needs to be unmounted (usenet stuff, transmission, virtual box)?

While I'm not sure of the exact process the new permissions script uses, the length of time it would take would likely have more to do with the number of files that need their permissions changed, rather than the size the occupy. It would take a lot longer to change permissions on 7.5 TB of pictures, than 7.5 TB of Blu-Ray ISO images. I do agree that all the drives probably should have been spun up. You could always change the permissions manually via terminal: chown -R nobody:users /mnt/user/sharename Where sharename is the name of one of your shares. You'd need to do this for each share.

Wouldn't it be 40000000?

Yeah - that's what it's reporting.

Once you've logged in via putty/telnet just paste them, all at once should be fine, and hit enter.

As long as when telnet terminates you can still see your terminal session (Windows will ususally drop you back at a command prompt without being able to see what happened), you should be fine. If you are using Windows, you can still use the telnet protocol, but use a client like Putty (it's free and available here): http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html Putty's default behaviour is to leave the window open if the connection is remotely closed.

Running the following from an ssh session works: flash=/dev/`ls -l /dev/disk/by-label| grep UNRAID | cut -d"/" -f3 | cut -c 1-3` # automatic id of flash drive while 1>2 do ((for d in $(ls /dev/[hs]d? | grep -v "$flash"); do hdparm -C $d | grep active ; done) | wc -l) sleep 60 done It'll run until you stop it or the server sleeps, checking the mount status of your drives every 60 seconds.

You could create a script that runs every minute with the following and output it to a file on your flash drive: for d in $(ls /dev/[hs]d? | grep -v "$flash"); do hdparm -C $d | grep active ; done) | wc -l I can't confirm this will work as I don't have access to my unRAID computer from work, but it's taken from your sleep script and appears to be the line checking to see if the drive is spun up or not. Then if it happens again, you'll know whether or not the drive was truly spun up. *EDIT* a better idea would probably to run the script from a ssh session (that doesn't automatically close its window if the connection is terminated).

Because of the way unRAID works it's always going to be slow at writing to disk (30MB/s is what I get). You can overcome this by using a cache drive and get faster write speeds (50-60MB/s), but a cache drive will eventually write to your array, and that will happen at 30MB/s. I suppose you could use all SSD drives, and that would be faster, but extremely expensive. I know at least on XBMC user was able to successfully stream 5 HD streams at once from unRAID. There are considerations in regards to your ability to do this. Ideally you would have a cache drive that moves files to your array drives when you wouldn't normally be streaming media (4am or whatever works for you). Also, unRAID is not a replacement for a proper backup. I don't consider backing up my commercial media as important as my personal media (family pictures, etc). The worst case scenario is I'd have to repurchase my media, I cannot recreate my personal media, so I have an offsite back up of things like that.

Is your computer connected directly to the router? If there's a switch in between try rebooting that as well.

I believe the last parity check being 15446 days ago is because you rebuilt the array. Even though it's the same disk, the array is considered new, and parity has never been checked. The same thing happens if you add another disk to the array, if I recall correctly.

Grab a flash drive, and copy the existing files from your flash drive to the new one, then run makebootable.bat on the new drive. You cannot backup your license (if you have one) as it's tied to the GUID of the flash drive. Hope that helps.

I use SSH keyfile based authentication to my router, and create a tunnel from there (also with SSH) to access my unRAID box. My router accepts SSH on a non-default port, and the keyfile I use is password protected. I feel pretty safe with this setup.

I had the same problem just this weekend. I'm at work right now so I can't provide the specifics of what I did, but here's an overview: I created a file in /boot/config called killoffenders - this stops my vm, and kills all the related services, and also kills Transmission, and makes sure a couple other things are no longer running (usenet/transmission/etc). The last thing it does is run umount -l /mnt/cache (forcing the cache drive to unmount lazily). All my usenet/vm/torrent services run from my cache drive and if something gets corrupt there I'm not too worried about it, I'd rather the machine shuts down safely when the power is out and deal with any cache issues later. I then opened the clean powerdown-1.02-noarch-unRAID.tgz file, added the line /boot/config/killoffenders to the file /sbin/powerdown after the line /etc/rc.d/rc.unRAID stop and saved the modified tgz. I'm still allowing the normal powerdown to be installed, and then I'm installing my modified one after, by adding a line to my /config/go file. I know I don't need to install both files. One caveat of this approach is that if you want to modify the configuration of the package you will need to modify the file you generated, or the modifications will be overwritten.
