Recommended Approach for upgrading drive
I have to replace a drive with some early smartctl errors, looking for advice on how to best proceed. I am going to be upgrading the size and also moving volumes round between a couple of drives tha...

You cannot have two volumes of the same name nor is it easy to change a volume name (see Changing-the-volume-name-on-an-os6-based-nas if you really want to do it). To get what you want, you'll need to use your backup to restore volume contents after you DESTROY and then replace each or an intermediary drive/volume. Since using an intermediary drive entails two copy operations, NAS-to-NAS copy from the backup may not be a lot slower.
To use an intermediary drive:
Add Volume3 in the empty slot.
Copy contents of Volume2 to Volume 3.
DESTROY Volume2.
Add new Volume2.
Copy contents from Volume3 to Volume2.
Delete contents of Volume 3.
Copy contents of Volume` to Volume 3.
DESTROY Volume`.
Add new Volume1.
Copy contents from Volume3 to Volume1.
You could use an external drive as intermediary instead, but it will take more time. Restore from backup is probably at least as fast.
If the drive in slot 1 isn't the primary volume (contains home folders and apps), then there is more to do. See How-to-save-your-apps-when-destroying-your-main-volume-OS6. If that volume was the first drive you put in, it should be primary. Otherwise, one of the others is. This extra step is needed if you use home folders or have apps installed, regardless of the method used to copy the volume contents.
FYI, the SSD with the OS is probably doing less than you think. The OS is in RAID1 on all drives, so having one with the OS only doesn't speed up OS access. It will speed up home folder access and app access if it's the primary drive.

also for clarity, I am not using X-Raid, using flex-raid... All volumes were created as JBOD.
I have already DESTROYED the other two volumes in preparation to restore to new devices.
However now getting a weird error, I have rebooted it several times to flush everything out, but now when I try to use front view it is prompting me dozens of times and forever for admin login and password, its not remembering it for any length of time, I have tried several different web browsers same result. Any idea what might be suddenly causing that?
I'm wondering if something in the OS was using some space on one of the other volumes I have DESTROY'd. Not sure why it would be, but that's the only thing I changed, destroyed both volumes, there is only one drive in the readynas now, the OS drive...and it SHOULD be functioning fine...but its becoming unwieldy to have to re-enter the admin login and password over and over again.
Also when I tried to then insert one of the new drives and add a flex-raid JBOD volume, its coming back with an error about can't find device or something like that.
So... somehow destroying the two non-OS JBOD volumes seems to have broken my OS functionality.

If the password hasn't changed, then this must be a browser issue.
