This is not an aswer for at least 5 reasons:

1) it's a test cluster
2) our metadata server is using 2.1GB
3) I have 4GB free on disk.
4) free disks is the same in each other server, only one is crashed
5) i'm expecting that, on a multimaster cluster, a bad metadata dump
doesn't kill the instances: for 2 reasons:
a) it's multimaster, metadata dump could be on another server
c) a server failure (for whatever reason) could move the current
leader on a different node, even without free space (metadata are kept
in ram)

So, why, with tons of free RAM available and a multi-master cluster,
out-of-space during dump will kill the master process on a follower?
I don't see any advantage in doing this.
