fatal error -- 117 - couldn't iget disconnected inode

30GB metadump image, 6.1GB compressed of ~7TB real partition

You need ~8-12GB of memory for xfs_repair on this.

I can also provide ssh access to the system with this image and all needed 
stuff, so you don't need to download it or waste own resources.

In meantime I'll probably make ugly hack by making "couldn't iget disconnected 
inode" non fatal, so repair will be able to finish.
