March 31, 200917 yr Currently I've got 2 raid5 arrays with 4 drives in each, and using lvm to make them 1 big volume. I'm looking to add a couple of empty drives, and start moving data over so I can convert this rig to unraid. Is there a simple way to accomplish this without having to move all my data to a non-raid disk and then move it back over to unraid?
March 31, 200917 yr Author Ok, would it be possible to do this: Stick a new blank drive in my machine Boot the machine up using unraid Make a new device using said new disk Restart back into old server Mount the device that unraid made and copy over data to it Essentially, can I mount an unraid created device consisting of 1 disk, no parity, in a normal ubuntu environment?

You can do this as long as you do not think that the disk will magically have parity protection once it is put back into the unRAID server. After you copy the data to the disk (mounted temporarily in the old ubuntu server) you can then un-mount the disk, then physically move it to the unRAID server and install it, and then power up. If you have not yet assigned a parity drive, you can then assign one and compute parity to have a protected array. If you had already assigned a parity drive, you MUST force a parity calculation (as it has no way of knowing you wrote to the disk behind its back). Expect lots of errors...as it corrects parity OR You can press the button labeled "restore" (which sets a new initial configuration, throws away any existing parity data, and then starts the process of calculating it new based on the currently assigned and working drives) The result is the same,a full parity calculation will occur, but it will not log the errors as it expects the parity disk to be invalid. Either way, you will not be protected by parity until you perform a full parity calculation. Once it is calculated, it again will immediately be invalidated by anything you write to any drive when the drive is mounted in another server. Joe L.
April 2, 200917 yr Author Well, I managed to get all of my existing data moved over to two large drives I borrowed from work. Currently my array is cleaning off my old drives. I have the two temp drives in the server (ext3 partitions) and obviously not assigned in any way. Once my array is 100% done, will I be able to log into the console and temp mount the ext3 drives and manually rsync my data over to the array? I'm hoping to do that, then just power down and remove the transition drives and be finally done.
