Memory does not serve me well (there are 28 disks, not 26!), but bash
history does :)
# gluster volume remove-brick BigVol replica 2
str957-biostq:/srv/arbiters/{00..27}/BigVol force
# gluster peer detach str957-biostq
# gluster peer probe str957-biostq
# gluster volume add-brick BigVol replica 3 arbiter 1

You obviously have to wait for remove-brick to complete before detaching

Give all the CPU and RAM you can. Less than 8GB RAM is asking for
troubles (in my case).
