We have local server machine in our small company. Its running with Debian 8 on two 120GB SSDs merged in RAID1 with this tutorial. https://blogging.dragon.org.uk/installing-ubuntu-14-04-on-raid-1-and-lvm/
Now we want to add 2 more 1TB disks, merge them in RAID1 as another RAID volume and redirect GIT repos and some mysql backup dumps there.
Our setup looks like this
md2 : active (auto-read-only) raid1 sda3 sdb3 2960384 blocks super 1.2 [2/2] [UU] md1 : active raid1 sda2 sdb2 113215488 blocks super 1.2 [2/2] [UU] bitmap: 1/1 pages [4KB], 65536KB chunk md0 : active raid1 sda1 sdb1 975296 blocks super 1.2 [2/2] [UU] unused devices: <none>
Ive read some tutorial https://www.howtoforge.com/software-raid1-grub-boot-debian-etch
And now want to do this:
- Create partitions on disks - sdc1 and sdd1
- Set Linux raid autodetect type for them
Merge them in one volume
mdadm --create --verbose /dev/md3 --level=mirror --raid-devices=2 /dev/sdc1 /dev/sdd1
Update mdadm.conf configuration
cp /etc/mdadm/mdadm.conf /etc/mdadm/mdadm.conf_orig mdadm --examine --scan >> /etc/mdadm/mdadm.conf
Do the rest of work - set filesystem, add fstab line etc ...
Is this a good approach or is not as easy as im thinking? For example will there any troubles with GRUB?
