Hi guys, I have a bit of an issue with my partitions/disks. I have 3 disks:
sda - 120G
sdb - 800G
sdc - 1TB
and want to use sda for the EFI partition and root, sdb for /home and sdc for data to be symlinked to the various folders (Music & Videos) but I’m not sure of two things:
I am intending to use the auto partitioner in order to setup BTRFS snapshots but don’t know whether to mount /home or let calamares create the mountpoints and add sdb later in fstab as @home or /home
Does it matter if I mount my data drive (sdc) as /DATA or should I use /mnt/DATA or /run/media/username/home?
I have been using opensuse recently due to the BTRFS rollback feature but I prefer arch and have tried many diffrent distros and set ups, including Manjaro (until the recent scandal/issues), EndeavourOS (which I like but would like a more ‘out-of-the-box’ approach to snapshots.
120 GiB for EFI partition is too much, in my opinion. I use 100 MiB, and even that’s almost empty. I am not dual booting, though, and if I did, I’d have OSs on separate drives.
Because I want to use the 800G drive for home, I don’t know if I should mount it as /home or @home, actually I don’t know whether to use EXT4 or BTRFS for my home partition either.
Hi @librewish, thank you for your blazingly-fast reply. I wasn’t expecting such a quick response.
Isn’t there a bigger risk of losing data by doing this? also, what about steam games that I install on there, should I turn off COW on those directories (if it is possible)?
Finally, what should I mount my data drive (EXT4) as?
there isn’t any existing data on sdb (both sda and sdb are SSDs) so I could use it as described but if I download a steam game to the SSD/s, should I disable COW?
My data drive is a HDD which has my music and films on it, I normally mount it to /DATA and then use symlinks as you describe but I have often wondered if /DATA is ok or should it be /mnt/DATA or /run/media/username/DATA?
If you have some permission/ownership oddities on your data drive ( I use /mnt/data myself - if it matters) - don’t forget to ask here before ‘fixing’ it Depending on your exact setup, it can be easily fixed - but knowledge of your setup and intentions can help determine which easy fix is appropriate…
this is my first outing with btrfs, so, pardon my lack of knowledge here.
before i do the btrfs device command i should format the second disk. do i need to mount it or will btrfs just take care of that?
i added a btrfs partition on /dev/sda which is actually my second drive.
when i issue the btrfs device add /dev/sda /home/sda
it returns no such file or directory. i figure im just missing an obvious step here.
my setup is a 128 gig ssd with /boot/efi and / on sdb, and i want to make home the entirety of /dev/sda. there is nothing on the sda drive.
