Disk space shortage

[Don Johnston]

I installed Linux Mint 13 LTS on my EeePC 901. "/" is on the 4 Gb SSD
and /home is on the 16 Gb SSD. The 4 Gb SSD ran out of space when I
tried to install some software.

I would like to continue to use the 4 Gb SSD for "/". I want to allow at
least 8 Gb for the /home partition if possible.

Suggestions would be appreciated.

Make a separate partition for /usr on the 16gb drive, and assign 8gb to /usr and 8gb to /home

 

Or perhaps more realistically, about 6gb for /usr and 10 for /home. Depends how much you expect to use.

hi Don,

Assuming you'll always have both SSDs connected at the same time, you
should create:

- A 200MB /boot partition on the primary SSD.
- An LVM physical volume across the rest of the primary SSD.
- An LVM physical volume across the entire secondary SSD.


You then define a single LVM volume group that includes both physical
volumes, which will give you a pool of storage of around 20GB.

You can then create LVM logical volumes of any size you like within that
20GB - if you want 6GB of / and 8GB for /home, you can do so. :-)


Note:

* This is assuming that both SSDs have comparable performance - this
setup isn't so good with drives of differing performance as it can slow
the faster drive down.

* Assuming both SSDs are always connected, you won't be able to remove
either SSD without breaking the filesystems. (without going to the
effort of LVM downsizing anyway)

* LVM is amazing, once done you can add, delete, shrink and grow
partitions at will, without any of the normal annoying partition table
issues.


regards,
jethro

Sounds good except that the 4 Gb drive is substantially faster than the
16 Gb drive. For that reason, I will probably use Kennedy's suggestion
of putting /usr on the 16 Gb drive. This will involve shrinking of /home
which contains data.
