I am running out of space with >1.1GB available. I have almost 44G free on my home. I want to change the mountpoint on my fstab but I am still a bit nervous if it will work.

Currently there is 7GB between /usr and /lib, I want to create an ISO file, and mouth it and change the mount points to that partition.

Another more traditional way is to resize my home and create new partitions for folders like /var/ or /usr/

Please help me decide which course of action to take.

Try gparted-live-cd/usb to resize partitions

I need to be non-destructive resizing.

gparted has that ability to non-destructive resize, however there is no guarantee that everything goes well so backup recommended (it is recommended anyway). When I get into free space on / problem due underestimation of partition size, I have created on my /home folders for /usr, /opt, /srv etc. and symlinked them to /. This is temporary solution, but there is nothing wrong with this (besides someone can have for example noexec on home, probably bind mount can help, but I did not tested it).

Running out of space on what, the / partition. If you have free space in the separate /home partition, you should be able to use GParted from a Live CD/flash drive to shrink it. Don't do it from GParted installed on your system.

Change the mount point of what to what? You say you have 7GB between /usr and /lib meaning each is on a separate partition. If that is the case, just create a mount point somewhere (/mnt directory) and then use to create a partition there and mount the filesystem. You could also shrink your home partition and do the same. I'm not sure exactly what you are trying to do, what your end goal is. If you want to create an iso and mount it you can do that in your /home partition. You might post more details on your final goal.

Changing partitions is not something trivial so if you have any important data, you need to back up before doing anything. For new users, it is generally a lot simpler to have a / and swap partitions then create different partitons for all these directories.

Well is exactly cuz I dont have the means to backup a 100GB partition atm that I want to do it the less intrussive possible. someone suggested to do a binary ball.

Like mkisofs -T -O <somefile>.iso /var; then edit the fstab as in mount -o loop <somefile>.iso /var

That way I dont really mess up with the partition table and can always make quick fixes if problems arrise in the future, like extending the filesize or generating other iso files.


Can anyone share any possible risk on going this route?

Can you post output of &Also use code or Quote tags around commands.

As I known iso filesystem is not writable. It also include additional garbage data (headers, etc.). Why just not make copy of /var into directory on free space and mount it with "mount --bind /partition_with_free_space/var /var".
