[Lustre-discuss] Lustre installation and configuration problems

[Carlos Santana]

Thanks Kevin..

I am referring to 1.8 manual, but I was also referring to HowTo page on wiki
which seems to be for 1.6. The HowTo page
http://wiki.lustre.org/index.php/Lustre_Howto#Using_Supplied_Configuration_Toolsmentions
abt lmc, lconf, and lctl.

The modules are installed in the right place. The '$ lustre_rmmod' resulted
in following o/p:
[root at localhost 2.6.18-92.1.17.el5_lustre.1.8.0smp]# lustre_rmmod
ERROR: Module obdfilter is in use
ERROR: Module ost is in use
ERROR: Module mds is in use
ERROR: Module fsfilt_ldiskfs is in use
ERROR: Module mgs is in use
ERROR: Module mgc is in use by mgs
ERROR: Module ldiskfs is in use by fsfilt_ldiskfs
ERROR: Module lov is in use
ERROR: Module lquota is in use by obdfilter,mds
ERROR: Module osc is in use
ERROR: Module ksocklnd is in use
ERROR: Module ptlrpc is in use by obdfilter,ost,mds,mgs,mgc,lov,lquota,osc
ERROR: Module obdclass is in use by
obdfilter,ost,mds,fsfilt_ldiskfs,mgs,mgc,lov,lquota,osc,ptlrpc
ERROR: Module lnet is in use by ksocklnd,ptlrpc,obdclass
ERROR: Module lvfs is in use by
obdfilter,ost,mds,fsfilt_ldiskfs,mgs,mgc,lov,lquota,osc,ptlrpc,obdclass
ERROR: Module libcfs is in use by
obdfilter,ost,mds,fsfilt_ldiskfs,mgs,mgc,lov,lquota,osc,ksocklnd,ptlrpc,obdclass,lnet,lvfs

Do I need to shutdown these services? How can I do that?

Thanks,
CS.
