Re: Getting glusterfs to expand volume size to brick size

[Nithya Balachandran <nbalacha@xxxxxxxxxx>]

What version of Gluster are you running? Were the bricks smaller earlier?

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?
