Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Today I tried this on my machine with OpenSUSE 12.3 (kernel 3.7):

# resize2fs /dev/mapper/system-srv 2G
resize2fs 1.42.6 (21-Sep-2012)
Filesystem at /dev/mapper/system-srv is mounted on /srv; on-line resizing required
resize2fs: On-line shrinking not supported

/dev/mapper/system-srv is an EXT4 volume.

Is it really unsupported or I am missing something?

As the message said, you can only grow a filesystem on-line. If you want to shrink it, you will need to unmount it first.

According to the ext4 filesystem maintainer, Ted Ts'o:

Sorry, on-line shrinking is not supported.
