Thanks itimipi. It did exactly as you said. I now have two of the three 2TB XFS drives swapped and rebuilt with the 4TB drives - working on the third. The last step will be moving all the data (2.5TB) from the two ReiserFS drives to the three 4TB XFS drives. I plan on using the unBALANCE plugin unless there is a better way. Yay! I'll finally be rid of ReiserFS. Thanks to all who replied, Robin

One last question. I have precleared all three of my 4TB drives so I am ready to make the swaps. I am going to remove one 2TB XFS drive and replace it with a precleared 4TB drive and then rebuild the array. The question is, when the rebuild is done, will the 4TB drive have 4TB of storage or 2TB since the old one was that size? Does the rebuild replicate the capacity also? Thanks again, Robin

I can't install this. It reports "Requirements Not Met". What requirements? It does not say.

Thanks! I like the remove, replace and rebuild idea. Some of my current drives are still Reiser FS. I would like to change them to XFS during this swap. If the removed 2TB RFS drive is replaced with a 4TB drive and rebuilt, it would retain the file system, correct? Any way around this? Or will this be two independent processes? Now that I think about it, I only have two RFS drives. The other three are XFS so I guess I could swap the 2TB XFS drives for 4TB then move the data off the RFS drives to them. Is that doable? Sorry for all the questions and thanks for the help! -Robin

My NAS currently has five 2TB drives and I want to replace them with three 4TB drives. What is the easiest and most reliable way to do this? I already have a 4TB parity drive and the NAS is about 2/3 full. Thanks, Robin

I have a small SSD for a cache drive. Can I just swap it with a 1 TB replacement without any special steps, i.e. shut down, swap drive and start up?

Thanks! I used unbalance to off load the drive and removed it according to the shrink array instructions. Seems to have worked just fine. Now I have one drive that is 99% full with the rest about 3/4 full. Is there a way to redistribute the files so that all are evenly filled? I have five 2 TB drives. Thanks again.

Sorry for the delayed response. I kinda forgot about it for a while... Yes, there is data on that drive. How do I copy just the data on that drive to the others? Can it be done through a web interface? Thanks.

I added a drive to my array that it turns out cannot be stuffed into the case. I really don't need the extra space so I want to remove it. My skill level with Windows and Macs are pretty high, but I admit I am not an advanced Linux user. Following instructions is no problem for me even if they are complex.

Is there an easy way to remove a drive from my UnRaid array. I want to make sure all the data on it is moved to other drives and the sharing is preserved. What is the best way to do this? Thanks!

Thanks guys. I wasn't sure if they always were gray but you confirmed it. Would be nice if they could follow the main screen color scheme though.

Sheesh. Silly me. I did not see that setting. Thanks! Now what about the colors in the dashboard? 🙂

I don't know when it happened but somewhere along the upgrade line the colors in the bar graphs disappeared. Can I get them back?

Robj, I didn't CHANGE the file system, it became an XFS drive only after I formatted it. I popped the replacement drive in right from the new WD box it came in. I ran the preclear script and when it passed I tried to assign it and here is where it gets fuzzy. I seem to recall that it would not allow me to assign the drive without formatting it first. That's when I chose XFS. The format completed and I assigned the drive and started the rebuild. At no point did any message or warning come up saying that what I was doing might be destructive. That's the thing that disappoints me. I had no clue that I was deleting a whole drive full of data. I'm in the tech biz myself and the steps I did seemed rather logical: take out a drive, pop in a new one, test it, format it, and start a rebuild. I suppose the format part is how I screwed up but in my experience with every OS I've worked with, a drive has to be formatted to be of any use.

Squid, will you be doing that? I really think it's needed. I can't be the only who's ever done this.
