[Gluster-users] Getting glusterfs to expand volume size to brick size

[Artem Russakovskii]

Hi,

I have a 3-brick replicate volume, but for some reason I can't get it to
expand to the size of the bricks. The bricks are 25GB, but even after
multiple gluster restarts and remounts, the volume is only about 8GB.

I believed I could always extend the bricks (we're using Linode block
storage, which allows extending block devices after they're created), and
gluster would see the newly available space and extend to use it.

Multiple Google searches, and I'm still nowhere. Any ideas?
