[Pati, Abhilasha]

Hallo ..

Thank you so much for the response.

Indeed, now i after checking the logs on MDS...i see the following.

I see an error that says that mounting server target with '-t lustre' deprecated.

Please note i have installed lfs 2.17.0.

Could this be an issue.

Many thanks,

Abi

Hello,

The issue seems to be with the MDT, kindly check the logs of the MDS
and also check the jobs stats on the MDT.
just my thoughts,

thank you,
