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: [r...@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. On Tue, Jun 16, 2009 at 11:36 AM, Kevin Van Maren <[email protected]>wrote: > I think lconf and lmc went away with Lustre 1.6.
