I just switched my wife's home computer to Ubuntu 18.04 from Windows 10, and she's liking the transition so far. It's an Ubuntu-only machine (no dual boot, only one OS distro, may need to set up a VM for certain Windows-specific applications).
One last thing to figure out and set up is how to handle the two drives (480GBb SSD, 1TB HDD). Tried installing with LVM enabled, but ran into the
lvmetad issue and had to go with standard
ext4 partitions (i.e., just
/ on the SSD, single unmounted
ext4 partition on the HDD that has the archive of her user data). She has almost 500gb of archaeological research data (many confidential/proprietary photos, .pdf's, and other data files) that would obviously overwhelm the SSD.
I'm trying to figure out how to set up so that
/home stays on the ssd (for speed, etc), with the bulk of the archival on the HDD. I'm not sure I want to just mount the HDD (e.g., as
/archive) with links to
/home, though, since I want whatever is pushed off to the HDD to also be exclusively part of her user space (i.e., not just generic storage accessible/visible to any other user account). Ideally, what I want is to create a subspace of
~/home on the HDD and have it usable and understandable to someone that has no interest in filesystem management and needs it to "just work" so that she can get to her data.
So far, all the two+ drive solutions I've seen just mount the HDD as bulk storage symlinked under
/home, sets up
/home as an LVM pseudo-RAID across the two (opinions vary whether that is a good idea, and
lvmetad prevents it for now anyway), or sets up an actual RAID (which I don't want to get into).
Unfortunately, all of this a hair beyond my understanding of Linux filesytems and it is very possible that I'm just not understanding this all correctly.
- Allow setup of multi-user system, with
\homeon the SSD and individual user access to large-file storage on the HDD
- user files and directories on HDD accessible only to that user, and linked under the user's
/home/[user]/[extra storage]on the SSD linked to
[hdd mount point]/[user]visible/accessible only to [user] as
- quotas not necessary but possible storage for space on the HDD
Basically, separate and secure individual user shares on the bulk storage device -- extending the user's home directory -- without pushing all of
/home to that second device.
Is there a way to set up what I'm describing, or can someone please point out where my thinking about the user filesystem structure is off-base?
