I just upgraded my lustre version from 1.8.1.1 to 1.8.4 and I can't reboot my lustre clients cleanly anymore. I am using the latest RHEL kernel and the openibd that comes part of that RHEL kernel + patchless lustre client installed from the tar ball.
The lustre client gets unmounted cleanly but the system deadlocks once the openibd driver is removed. I had to modify the openibd stop script to include "umount lustre" and "lustre_rmmod" as a work around. The following is the error message that I get when I try to reboot the lustre client: Scientific Linux SLF release 5.3 (Lederman) Kernel 2.6.18-194.11.1.el5 on an x86_64 INIT:Shutting down smartd: [ OK ] Stopping atd: [ OK ] Shutting down process accounting: [ OK ] Stopping xinetd: [ OK ] Stopping autofs: Stopping automount: [ OK ] [ OK ] Stopping acpi daemon: [ OK ] Shutting down ntpd: [ OK ] Unmounting network block filesystems: LustreError: 3697:0:(ldlm_request.c:1025:ldlm_cli_cancel_req()) Got rc -108 from cancel RPC: canceling anyway LustreError: 3697:0:(ldlm_request.c:1587:ldlm_cli_cancel_list()) ldlm_cli_cancel_list: -108 Lustre: client ffff81020f145400 umount complete [ OK ] Unmounting NFS filesystems: [ OK ] Stopping system message bus: [ OK ] Stopping RPC idmapd: [ OK ] Stopping NFS locking: [ OK ] Stopping NFS statd: [ OK ] Stopping portmap: [ OK ] Stopping PC/SC smart card daemon (pcscd): [ OK ] Shutting down kernel logger: [ OK ] Shutting down system logger: [ OK ] Unloading OpenIB kernel modules:NET: Unregistered protocol family 27 Failed to unload rdma_cm Failed to unload ib_cm Failed to unload iw_cm LustreError: 131-3: Received notification of device removal Please shutdown LNET to allow this to proceed INFO: task rmmod:4151 blocked for more than 120 seconds.
