Hi again,
I am pretty sure this is it though. I remember having to deal with it
while working on lustre.

And are you _sure_ lustre 2.10 was installed on the node you
compiled/built robinhood's rpms?

Unfortunately the behavior is still the same.
Thanks,

Hi Lorand,
I seem to remember this is caused by an update of lustre's changelog API.
Did compile robinhood against the right version of liblustreapi? (there is no
need for ioctl in Lustre 2.10's API)

Hi Thomas,
I actually did that already but forgot to add the strace lines to the initial
email. But it is still unclear to me why open function is called with the
O_RDONLY flag.
[pid 2348817] open("/cluster", O_RDONLY|O_NONBLOCK|O_DIRECTORY) = 12
[pid 2348817] ioctl(12, _IOC(_IOC_WRITE, 0x66, 0x94, 0x08), 0x7ffef3f20240) =

Hello,
If you run "strace -f robinhood --readlog" you should see the ioctl that
causes this error, and its arguments.

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.
