feature request - tool for offline expansion
I have a readynas ultra plus with four 3 TB drives, configured as X-RAID2. I cannot further expand the volume because I will hit the 8 TB lifetime expansion limit. This is because when I first con...
Yes, that is what I want.
I have previously seen this guide, but I was put off by Chirpa's comment that expanding using this trick was destined to ultimately fail because the tools were not 64bit clean. I don't understand the implications of Chirpa's comment. Chirpa seemed to be talking about the 16 TB limit, which isn't my issue; I don't know if his warning applies to using the method to expand beyond 8 TB over the initial filesystem size, which is my issue.
I realize that expansion is always a bit dangerous, so backups are essential for critical data. But I don't want to waste time doing something that is certain to fail.
Bottom line: netgear's documentation recommended adding disks one at a time, and didn't mention the 8 TB expansion issue. Big mistake, to myself and others on this forum. I would like to see the company set things right by testing the method in the post you cite, and letting us know if works, albeit with risks. If it does, I think they should provide a user friendly add-on to facilitate the process (though I myself could probably handle the command line approach).
