I am stuck with the following issue on a client attached to a lustre system. we are running lustre 1.8.5 somehow connectivity to the OST failed at some point and the mount hung. after unmounting and re-mounting the client attempts to reconnect. lctl ping shows the client to be connected and normal ping to the OSS/MGS servers shows connectivity.
remounting the filesystem results in only some files being visible. the kernel messages are as follows: --------- Lustre: setting import lustre-OST0003_UUID INACTIVE by administrator request Lustre: lustre-OST0003-osc-ffff8110238c7400.osc: set parameter active=0 Lustre: Skipped 3 previous similar messages LustreError: 14114:0:(lov_obd.c:315:lov_connect_obd()) not connecting OSC ^\; administratively disabled Lustre: Client lustre-client has started LustreError: 14207:0:(file.c:995:ll_glimpse_size()) obd_enqueue returned rc -5, returning -EIO LustreError: 14207:0:(file.c:995:ll_glimpse_size()) Skipped 1 previous similar message LustreError: 14207:0:(file.c:995:ll_glimpse_size()) obd_enqueue returned rc -5, returning -EIO LustreError: 14686:0:(file.c:995:ll_glimpse_size()) obd_enqueue returned rc -5, returning -EIO Lustre: 22218:0:(client.c:1476:ptlrpc_expire_one_request()) @@@ Request x1363662012007464 sent from lustre-OST0000-osc-ffff8110238c7400 to NID 10.9.89.21@tcp 16s ago has timed out (16s prior to deadline). req@ffff810459ce4c00 x1363662012007464/t0 o8->[email protected]@tcp:28/4 lens 368/584 e 0 to 1 dl 1300678232 ref 1 fl Rpc:N/0/0 rc 0/0 Lustre: 22218:0:(client.c:1476:ptlrpc_expire_one_request()) Skipped 182 previous similar messages Lustre: 22219:0:(import.c:517:import_select_connection()) lustre-OST0000-osc-ffff8110238c7400: tried all connections, increasing latency to 18s Lustre: 22219:0:(import.c:517:import_select_connection()) Skipped 203 previous similar messages ------------ an LS of the filesytem shows drwxr-xr-x 4 amcpherson users 4096 Mar 19 10:38 amcpherson ?--------- ? ? ? ? ? compute-2-0-testwrite ?--------- ? ? ? ? ? hello ---------- other clients on the system are able to mount and see the files perfectly well. can anyone help with what the errors above imply. a simple network connectivity issue does not seem to be the case here, yet the client attempts to re-connect to the OST, fail.
