 Description   

Each time i unmount/remount a client, i see the following message on my combo MDT/OST server:

Lustre: 15619:0:(ldlm_lib.c:871:target_handle_connect()) MGS: connection from 1ab2d9ae-7ad1-f922-daaf-3ba6549f94db@10.10.4.12@tcp t0 exp (null) cur 1326111941 last 0
Lustre: 15619:0:(ldlm_lib.c:871:target_handle_connect()) Skipped 3 previous similar messages

int target_handle_connect(struct ptlrpc_request *req)
{
[...]
        CWARN("%s: connection from %s@%s %st"LPU64" exp %p cur %ld last %ld\n",
               target->obd_name, cluuid.uuid, libcfs_nid2str(req->rq_peer.nid),
              target->obd_recovering ? "recovering/" : "", data->ocd_transno,
              export, (long)cfs_time_current_sec(),
              export ? (long)export->exp_last_request_time : 0);

I think such messages should be prohibited and just moved to D_INFO or D_HA, since it will flood the server logs on large cluster.

Hi Johann,

HA is enable by default in debug. Should we use "info"?

Comment by Johann Lombardi (Inactive) [ 10/Jan/12 ]

HA is fine since it is not printed to the console.
