/tmpfs is in RAM, so not to worry about that when it comes to partitioning.

And no, I wouldn't use RAID-0 on the root partition - on a production server, that's asking for trouble. Rather have 70-something GB available and have it safeguarded against failures, than 140-something GB and lose it all when one fails. But that's just my thought

Thanks Myatu!

I don't think you can save a lot of space by putting the system on raid 0 since the system itself doesn't take that much space.

Do you think I should change the tmpfs to the default OVH value after the re-install?

You want to use raid-1 on the root directory? You could change / to be raid-0 and have a lot more space if you wished. The tmpfs is just space used on the root, as /tmp is on /.

You can change the size of tmpfs in configuration files after installation if you wish.

You will not see the swap with df -h and tmpfs doesn't use the swap space. It's simply a virtual fs that's setup for the /tmp folder to provide some security.

Personally; I don't see why you would ever need any swap space on an MG considering how much RAM that mother has. I would re-install without swap at all, or at very least no more than 1GB swap per drive.

What do you think about this partitioning? I don't really use the /home directory so that's why I wanted to do a re-install.

Will tmpfs still be the same size as before?

I just got an MG SSD and I definitely want to reinstall setting my custom partitioning but just in case I mess up it would be nice to know.

I'm asking because fdisk -l and df-h it's not clear enough for me. It says it has 1 Gb of swap (top) but df -h indicates

Filesystem Size Used Avail Use% Mounted on
/dev/md1 5.0G 966M 3.8G 21% /
/dev/md2 69G 180M 65G 1% /home
tmpfs 7.9G 0 7.9G 0% /dev/shm

I used to think tmpfs was somewhat related to the swap space
