Hi all
So I've been busy the last few days swapping out each of my x4 3TB drives for x4 6TB drives. All done by manually failing one drive at a time in the RAID and then adding its replacement.
I know I now need to grow the RAID before growing the file system, and it appears that needs to be done in CLI and not in the GUI. My query is what commands do I need to run in CLI to do this (and do I need to run anything beforehand to make sure I do this right?)
I've got the same number of drives before and after, so is it simply mdadm --grow /dev/md0 --raid-devices=4 or a variation of that?
Thanks
Adrian
