April 21, 201214 yr Is there any way I can replace the motherboard, CPU, memory, then hookup my current five drives (three data, one cache, one parity), and have the array leave off where it was? Or do I have to start over? Thank you.

Or do I have to start over? Thank you. absolutely.. that is one of the best features of unRAID. V4.7 is a little bit of work. you need to know what drive was in what slot. you should get a screen print of your array/drive assignment page. then reassign each drive to the correct slot. V5x is pretty much automated. move the drives and flash to a new system and power it on. DO NOT START THE ARRAY if any drive thinks it is unformatted (the parity drive will be unformatted by default). I would of course recommend a non-repair parity check before and after migration to make sure everything is good. if the system is shot. you are sort of stuck on the pre-move check.
April 21, 201214 yr Author Thank you. The system semi-works. I get about 20 minutes or so out of it, then something fails. So, I can take a screenshot at least. I do have 4.7. Speaking of this, should I "upgrade" to a newer version? I just chose 4.7 since it wasn't beta. But there are quite a lot of betas.

Or do I have to start over? Thank you. The cool thing of unraid is that all the primary stuff needed to support your array is on the USB drive, so YES (!) replace motherboard, re-enter USB stick and all should work. Remember though that this is kind of an on-the-edge move, so do the action, reboot and see what happens, if disks end up showing as unformatted or unrecognised then get back on the forum for specific advice. All your drives have their info, if you can hook them up to a linux station they will be fully readable. At this point the worst thing you can do is do something "stupid" to your disks (like accidentely formatting them). 1) replace motherboard (set bios to auto-boot from usb stick) 2) reboot 3) see what happens, if array starts and only your parity drive is gone you need to rebuild parity, in all other cases, check back with the wizzards online over here.

Make the screenprint, then replace motherboard. In a situation like this you do not want to change more..
April 28, 201214 yr Author Well, I replaced my motherboard, memory, and processor, for $150. I then restarted everything. I have 4.7, and the configuration wasn't remembered. I just used my printout of the configuration, reset everything correctly, and it appears to be working. The parity check is currently at 40%.
April 30, 201214 yr So I had a question regarding accessing a drive that I pulled from an unraid box and reading it. If I do not have a current linux box, would some of the apps listed at this web page work as well? Or has anyone used any of these apps? http://www.howtoforge.com/access-linux-partitions-from-windows
April 30, 201214 yr That seems to apply to ext2 or ext3 filesystems which unRAID does not use. There are reiserfs utilities. A google search should turn up something. One way is to simply use a spare computer. Unhook the current HDD's, connect the unRAID drives you want to read, boot from an unRAID USB (even the free version works) and then assign the drives as data drives and read them over the network. No need to set parity and you can read 2 drives at once with the free version by doing this.
April 30, 201214 yr Thanks lionelhutz. I appreciate it. I was also thinking of a live linux install on cd like knoppix. I would think that this would also work.
April 30, 201214 yr Boy do i need to search before I post my dumb questions... Heres a topic already dedicated to this: http://lime-technology.com/forum/index.php?topic=2057.msg14950#msg14950
