Subject: Drive Replacement
Date: Sat, 22 Oct 2016 09:03:16 +1100	[thread overview]
Message-ID: <CA+WRLO-XY2aai7z8436yna14cjbRsPrWgHwxbcf5Kq_-7RENCQ@mail.gmail.com> (raw)

I've got a BTRFS array that is of mixed size disks:
2x750G
3x1.5T
3x3T
And it's getting fuller than I'd like. The problem is that adding
disks is harder than one would like as the computer only has 8 sata
ports. Is it viable to do the following to upgrade one of the disks?

A) Take array offline
B) DD the contents of one of the 750G drives to a new 3T drive
C) Remove the 750G from the system
D) btrfs scan
E) Mount array
F) Run a balance

I know that not physically removing the old copy of the drive will
cause massive issues, but if I do that everything should be fine
right?
