Hello,
I am getting low on space in my /(root) partition. I have 23GB free.
I have 350GB in my /home partition. I am the only user.
I was experimenting with virtualization and it causes the root partition to get very low. I would like to move /var from the root partition, to the same partition as /home, if that's safe to do.
Or, resize /home and add another partition for /var
I also don't want to screw the pooch doing it.
This is over my head. The more I read about it, the more confused I
get.
The way I've been doing it for quite some time is to make /var a separate partition, put the home directories on /var/home, and then bind-mount /var/home on /home. In /etc/fstab that's:
/var/home /home none bind 0 0To keep SELinux happy, you need to set up an equivalence of /var/home to /home:
semanage fcontext -a -e /home /var/homeIt's all completely transparent in the running system. The only time I have to remember that it's set up that way is when I'm looking in my backups and need to know that home directories are backed up as part of /var.
Alternatively create /home/VM and keep the virtualised disks in there.
This is the solution I would use. I use < 80 GB for / which makes it cheap
for /
to be an SSD (I use 120 GB SSD but every system, < 80GB is actually used, most < 60GB is actually used).
Databases and other stuff that take up space are in a /srv on its own
platter
disk rather than in /var - I would do a similar thing with VM images.
It's nice to be able to do a fresh completely wiping the old root
partition and
then be able to mount your other partitions and change a few config files
and
be back up and running. Keep a small physical disk like an SSD just for /
makes
that easy.

I was about to head off to Bestbuy and pickup a 1TB SATA drive but I think I'm going to hold off for now and use /home for the VMs.
Thanks!!
