[lustre-discuss] Check clients connected?

[Hanley, Jesse A.]

I usually check the exports:

echo > /proc/fs/lustre/mdt/*MDT*/exports/clear

ls /proc/fs/lustre/mdt/*MDT*/exports/

And then the request history (lctl get_param mds.MDS.mdt.req_history) for anything current.

    Hi all,
    
    I've now hopefully completed my migration to our new lustre filestore. 
    Is there any way I can check to see if any clients still have the lustre 
    filesystems mounted from the old MDS/OSS I do have one test machine that 
    I know is, but want to make sure none of the others do before shutting 
    the old servers down.
    
    Cheers.
    
    Phill.
