So I had an asymmetrical Raid1 as a basic file server. One drive was .5Tb and the other was 2Tb. I just replaced the .5 with another 2Tb, and I'm trying to resize the filesystem to match the new size.
My issue is functionally identical to the one in this thread, so I followed the same instructions, ie forcing mdadm to resync to the max capacity. However now that it's completed, the webclient still is showing the former size, and the thread essentially stops after running this command. What do I need to do to get it the right size? My guess was to ssh into the system and run parted, but I figured there's a better way to do this.
EDIT: After looking around on the forum, it looks like doing a Raid1 was a bad idea from the get-go (or at least should have been migrated at some point over the past couple of years). Since I have the old drive and no new data had been added, could I create a btrfs pool with the 2Tb drives, plug the old drive into my desktop, and copy everything over?
