Re: [HPDD-discuss] Lustre-2.4 VMs (EL6.4)

Ofcourse I've checked it, eth0 is present and it is up (used as internal network between the VMs). The other interface eth1 (Host Only adapter in VirtualBox) used to connect from Host to Guest(VM). The log messages were taken during boot. After logging in, "modprobe -v lnet" does not show anything(already loaded). But "modprobe -v lustre" shows insmod /lib/modules/2.6.32-358.6.2.el6_lustre.g230b174.x86_64/updates/kernel/fs/lustre/mdc.ko insmod /lib/modules/2.6.32-358.6.2.el6_lustre.g230b174.x86_64/updates/kernel/fs/lustre/osc.ko insmod /lib/modules/2.6.32-358.6.2.el6_lustre.g230b174.x86_64/updates/kernel/fs/lustre/lov.ko insmod /lib/modules/2.6.32-358.6.2.el6_lustre.g230b174.x86_64/updates/kernel/fs/lustre/lustre.ko The service status is: # service lnet status running # service lustre status partial # service lustre stop # service lustre status partial # service lnet stop Removing module lustre ERROR: Module osc has non-zero reference count. # service lnet status running So the reloading of lnet/lustre is not working here.
