First, sorry if the question has already been asked and correctly answered, I did not find anything that satisfies me.
I rent a dedicated machine in a datacenter, the machine run with a Debian 10 and has two drives in RAID 1, there are 3 partitions: one for the boot, one for the swap and one for the rest.
The third (/dev/md2) uses the ext4 file system and I would like to use XFS instead.
I am not used to changing the filesystem and this is the first time I have a machine with RAID so I do not know how to do it.
This is a new installation so there is no risk of losing data.
I tried a mkfs.xfs /dev/md2
but it didn't work:
root@Debian-105-buster-64-minimal ~ # mkfs.xfs /dev/md2
mkfs.xfs: /dev/md2 contains a mounted filesystem
And I don't know how it should be unmount/mount due to the RAID.
Thank you in advance for the help.
