Don't think so, as I never heard about "Robin Hood" in the context of

The setup is pretty simple, devices were created with

mkfs.lustre --fsname=lustre --mgs --mdt --backfstype=ext4
--failnode= at tcp --verbose /dev/mapper/MGTMDT


mkfs.lustre --fsname=lustre --ost --backfstype=ext4
--failnode= at tcp --mgsnode= at tcp
--mgsnode= at tcp --verbose /dev/mapper/OST0000


The only "add-on" we have is quota support. Back in 2.1.5 that was
enabled with:

lfs quotacheck –ug /lustre
lfs quotaon /lustre

The file system is mounted on about 200 nodes and accessed by cluster

Best regards,
