As you might suspect, the correct answer is 'lnet.debug' # sysctl lnet.debug lnet.debug = ioctl neterror warning error emerg ha config console > > cat /proc/sys/lnet/debug > gives output: > ioctl neterror warning error emerg ha config console > > cat /proc/sys/lnet/subsystem_debug > undefined mdc mds osc ost class log llite rpc lnet lnd pinger filter > echo ldlm lov lmv sec gss mgc mgs fid fld > > manual says that in order to set reasonable production debug level one > need to put numeric value into debug files like below: > echo 0x3f0400 > /proc/sys/lnet/debug > Will this work under lustre 1.6.3 or maybe it is old reference from 1.4 > release and there is new way of changing lustre debug level in new > releases? The hex bitmasks will work with 1.6.3, however we have added nice human-readable strings. '-1' will still set all values 'on' and is a simple way to see the entire list.. # echo -1 > /proc/sys/lnet/debug # cat /proc/sys/lnet/debug trace inode super ext2 malloc cache info ioctl neterror net warning buffs other dentry nettrace page dlmtrace error emerg ha rpctrace vfstrace reada mmap config console quota sec # echo "ioctl neterror warning error emerg ha config console" > /proc/sys/lnet/debug # cat /proc/sys/lnet/debug ioctl neterror warning error emerg ha config console cliffw > > Thanks, > > Wojciech Turek > > > > ------------------------------------------------------------------------ > > _______________________________________________ > Lustre-discuss mailing list > [email protected] > https://mail.clusterfs.com/mailman/listinfo/lustre-discuss _______________________________________________ Lustre-discuss mailing list [email protected] https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
