January 6, 201511 yr So, before I do something I shouldn't I thought I'd make sure I'm doing the right thing. Backstory: last week I replaced my old 4TB parity with a new 6TB drive, everything went fine. Today I wanted to do a little maint. and stopped my array. I removed an old 2TB drive and placed in it's place a new, pre-cleared, 6TB drive. At the same time I added another drive to be pre-cleared (the old 4TB parity) onto an open SATA slot on the MB. Good so far. I restarted the server and everything looked good. The unassigned drive slot I reassigned the new 6TB drive. Now the GUI says "Stopped - upgrade disk" and the start array button indicates that the array will start and the data be rebuilt. Press the button and GUI becomes non-responsive, went on for about a 1/2 hour without signs of life. I was able to telnet in and reboot the server. Now: on the disk status page all disk assignments are fine (including the new 6TB). The New disk has a yellow ball. The Array stays says "Stopped. Configuration valid". And the text near the array start button says "Start will bring the array on-line and start Data-Rebuild." Everything looks OK. What I'm worried about is the aborted array start doing something bad. The "configuration valid" seems odd, shouldn't that still be "upgrade disk" I'm probably being way overcautious, but I've been burned before. Thanks for any help.

Start the data rebuild and after it is done do a non correcting parity check to ensure the new data disk was rebuilt okay. Keep your old data disk for now until it has finished the rebuild and you have done a Non Correcting parity check, i.e. untick the box. Any problems you still have the old data disk.
January 7, 201511 yr Author I decided that since I had the data disk I would just go ahead. Looks like it's working fine. One other issue, that I don't know if it is related: I can't get to unmenu anymore. Tower:8080 doesn't respond.

Unmenu isn't picky like emhttp, you can start/restart it no problem. Just type /boot/unmenu/uu in a telnet prompt and you should be back in business as far as unmenu goes.

I'm going to not tempt fate and let the rebuild complete before I do anything. Then i'll play with unmenu.
