thanks for all the help guys, my server is now running on the 3 x 10tb drives and everything is looking healthy.

OK Thanks. Before I do this i was going to run a parity check again with the write errors unchecked, is there a faster way to do this or will this be another 20hr round before i can safely shutdown and swap the drive out?

Thank you! Last thing the on this topic based on your last post. Once my parity check is done and everything is ok in order to replace the last 4tb drive should I do the following shutdown the array unassign disk 1 (the 4tb drive that has my data) start array Stop the array assign the new 10tb drive to disk 1 start array

How do you do a parity rebuild for future reference?

Thank you so much for the info this is very helpful. I was mistaken in the directory I mentioned I did actually create the folder in mnt/disk2 not /mnt/user/disk2 as you mentioned. After the parity rebuilt drive2 I was trying to stop the array in order to do the new config but it looks like the array was just hanging in the stopping state. I hard rebooted the server and then canceled the parity check after the reboot. I then stopped the array and did a new config. In the drive assignments I set disk 3 to no device and set disk 2 to the new 10tb drive and checked the box that parity is valid and started the array. My current configuration is 10tb parity drive, 4tb disk1 and 10tb disk2. After all this it seems like all is fine but I decided to do a parity check with the write corrections checked before trying to swap out the last drive which actually has some data on it, disk1. Currently there is this parity check running and it seems to have found a ton of errors. I still can access my shares and all my data seems to be here. Based on what I have read about the errors it seems like this parity check with the write correction box checked should fix any parity issues so I can continue on to stopping the array and swapping disk1 out for the last 10tb I have. Does this sound ok? I didn’t see any responses yesterday so I just went ahead with what I mentioned above thus far so I can’t go back and undo how I did things up to now. I wasn’t so concerned if things blew up because although inconvenient I don't have to much on the array yet and have all that data on Dropbox as a backup but would rather not have to go that route. any suggestions based on my current state would be helpful, and thanks again for helping.

It looks like the parity sync / data rebuild completed. Is there a way for me to see if the clean disk is done so I can stop the array and do a new configuration?

Hi, The entire process i did so far was the following: 1. Stop array pull the 4tb parity drive and replace with 10tb drive, reassign in the main screen and start array. it did its rebuild/sync and after about 20hours completed. 2. Stop array pulled disk3 drive and replace wiith 10tb drive, reassign disk 3 in the main screen and start array. it did its rebuild/sync and after about 20hours completed. 3. I stopped the aray and then set disk2 to no device and then started the array thinking that since its empty and unused it would not be more complicated then that. It didn't remove the drive and then I did some research and found this clear an array drive method so I started the array back up and did step 4. 4. Installed user scripts plugin and downloaded clear_an_array_drive.zip and created a folder in the correct plugins directory "clear an array drive" and put the script and description file in there. Additionally added the clear-me folder in /mnt/users/disk2 which was totally empty and then started the plugin. Now after all these steps I am at the stage of having a running parity sync which I am not sure if its part of the clear an array process or because I set disk 2 to no device and started the array as well as a 10tb parity drive a 10tb disk 3, an empty 4tb disk 2 which i am trying to remove and a partially full disk 1 which I plan on swapping with my last 10tb drive once disk 2 is full removed. When you say "After you do a New Config, it will give you a parity valid checkbox when you go to Start the array." where will i see this checkbox, after i hit the button start array, or is it somewhere on the main page or is it on the new config page? Is the way I am doing this, thus far ok and how can I see the progress of the clean an array disk? PS This is not an old array with a lot of data, its pretty new I have just not realized all the features of unraid and now want to use the server for a gaming / nas box and having 3 drives allows me to remove a drive cage so i can fit a full length gpu with the added benefit of 20tb usable vs 12tb usable so the only drive that has data on it are the cache drives and disk1. PS Sorry if this is long winded but just trying to give all the background info. My end goal is to have just the 3x 10tb drives.

Hi all, I am attempting to shrink my array from 4 x 4tb drives to 3 x 10tb drives. I have replaced 2 of the 4tb drives with 2 10tb drives and each time did a parity sync and am now looking to remove/shrink the one 4tb drive that is totally empty before swapping the last 4tb drive for a 10tb. I have read the page on doing the shrink via the user scripts plugin and was able to start the script with no problems via the plugin. I would like to make sure I don’t screw anything up in the process and am looking for clarification. I left the user scripts page open displaying “closing out this window will cancel the script” but I was under the impression that I was supposed to be able to see a progress bar. How do I see that progress bar, do I have to type ! to see it? It looks like there is a parity sync running, how can I verify the script is running properly as well and roughly how long will it take in peoples experience. Once this script/parity sync is done and I go to tools and do a new config, set the disk I want to remove “disk2”to no device and start the array will that disk disappear? I do not see the checkbox mentioned in the instructions that says “parity is already valid” is this on the new config page or the main page where I do the drive assignments? Will this only show up after the current parity sync completes? thanks in advance for any input.
