Is it feasible (also known as secure) to resize a dividing while the system is running?

I'm speaking about resizing my origin dividing (/), while the system gets on (I recognize that is generally difficult, yet I'm simply wishing there is some means to do it). I need to know if there is some means I can boot the system up in read - just setting (without a real-time cd, simply in instance), and also resize/.

If it can not function, I recognize, as that is what I currently recognize to be the instance (yet you never ever recognize = P)

I concur with the earlier comment. I would certainly simply include in make great BACKUPS prior to trying anything similar to this. I additionally located that I can do this just if the dividing is unmounted, along with all dividings hereafter one on the hard drive. I saw this when trying to combine 2 dividings with each other, by first removing one, liberating room, and afterwards including the released room to an existing dividing.

I was informed that all dividings over the one to be raised have to be unmounted first. I did unmount it, and also combined the dividing. It achieved success.

BUT do back-ups back-ups back-ups back-ups did I claim BACKUP?

Some filesystems sustain "on - line" resizing, and also because instance I would certainly consider it sensibly secure unless the manpage/program advises it is not.

The majority of filesystems that sustain "on - line resize" just sustain making it bigger (as an example XFS, ext2/3/4, reiserfs).

Btrfs sustains on-line growing , yet certainly it is not as secure as a lengthy - existing filesystem like XFS or ext4 yet.
