[Lustre-discuss] High CPU load, only on 1 OSS

[Ronald K Long]

We recently setup a lustre config.  1 MDS 4 OSS's.  Everything is running 
fine except on the first OSS we are experiencing very high cpu load.  The 
first OSS is running a CPU load in the high 50's.  The other 3 OSS's are 
steady at around 8.  Everything is the same between all of the OSS's.

The stripe is setup 

stripe_count:   1 stripe_offset:  -1

Red Hat 5 64bit

kernel-2.6.18-194.3.1.el5_lustre.1.8.4
kernel-devel-2.6.18-194.3.1.el5_lustre.1.8.4
lustre-ldiskfs-3.1.3-2.6.18_194.3.1.el5_lustre.1.8.4
lustre-1.8.4-2.6.18_194.3.1.el5_lustre.1.8.4
lustre-modules-1.8.4-2.6.18_194.3.1.el5_lustre.1.8.4


Any thing I can check on the problem OSS to rectify this issue.

Thank you in advance
