Hi,
We've recently upgraded to Lustre 2.10.5 and to Robinhood to 3.1.4.
Processing changelogs fails now with "ERROR -25 opening changelog for MDT
'scratch-MDT0000': Inappropriate ioctl for device".
Could you please advice on how to solve this? Note that currently MGS and MDS
are running on two separate servers.

MDT {
mdt_name = "MDT0000";
reader_id = "cl4"; # yes, it is cl4
}
force_polling = ON ;
polling_interval = 60s ;
}
