Growing (really grow) a raid1 (mdadm --grow)
I need to increase a RAID1. I followed a post in another forum which told the following actions:
What is wrong in that?
I even did that under a rescue system, because the raid1 is where my real /usr is. From reading about growing a raid 1 I got the impression, that it should be doable even in a running system.
Thank you for your answers.
Best regards and a happy new year
I did similar steps (without disk repartitioning --- raid was using only part of the disk initially)
and it worked. Might be because raid/md module doesn't know the partition size changed.
* What's the error after step 8?
* Have you tried --size=NUMBER?
* Could you restart the raid before step 8?
