Resize block storage volume with less/no downtime?
After resizing a block storage volume, the guide recommends to reboot, unmount, fsck, resize the fs and re-mount. Is it possible/safe to resize without reboot, fsck and perhaps even unmount?

I believe you must unmount before the resize can happen…otherwise the volume will be "busy."

I'm used to live resizing of xfs, but it seems like ext4 also supports it: https://unix.stackexchange.com/questions/143675/extend-partition-size-without-unmounting-it
Guess there are reasons why Linode doesn't recommend it, but would be nice to know why.

My guess is that the block-storage volume is virtual…that there is some virtual structure that represents (and resembles) a physical storage volume to you.
