I tested a lustre client using SPECSFS. SPECSFS clients are 3. I mounted a lustre client with nfs. But I couldn't succeed that test. I got LusterError message in lustre client. May 6 16:31:14 node3 kernel: LustreError: 2148:(rw.c:115:ll_truncate()) truncate on inode 1319 with no objects . . . so many errors.. Do Lustre client mounted with nfs have some troubles for sometimes? Tell me about this, please.

A small test cluster could get by with fewer, but a larger cluster benefits from the parallelism of having more threads, and the defaults are set accordingly. Thanks-- -Phil

We expect to deliver a more robust and performant NFS re-export in Lustre 1.4.x. We have not tested SPECSFS against Lustre, so it''s certainly possible that it is doing operations that we have not tested. -Phil
Hi, I''ve installed Lustre file system 1.0.4 on a test cluster and find around 20-30 copies of the following processes. Are these created/required by the Lustre file system ?? 1 S 0 2134 1 0 75 0 - 0 - ? 00:00:00 ldlm_bl_00 1 S 0 2135 1 0 75 0 - 0 - ? 00:00:00 ldlm_bl_01 1 S 0 2166 1 0 84 0 - 0 - ? 00:00:00 ldlm_cn_00 1 S 0 2167 1 0 84 0 - 0 - ? 00:00:00 ldlm_cn_01 1 S 0 2198 1 0 75 0 - 0 - ? 00:00:00 ldlm_cb_00 1 S 0 2199 1 0 75 0 - 0 - ? 00:00:00 ldlm_cb_01 1 S 0 18448 1 0 75 0 - 0 - ? 00:00:00 ll_ost_00 1 S 0 18449 1 0 75 0 - 0 - ? 00:00:00 ll_ost_01 1 S 0 18732 1 0 75 0 - 0 - ? 00:00:00 ll_mdt_00 1 S 0 18733 1 0 75 0 - 0 - ? 00:00:00 ll_mdt_01 1 S 0 18763 1 0 85 0 - 0 - ? 00:00:00 ll_mdt_attr 1 S 0 18764 1 0 85 0 - 0 - ? 00:00:00 ll_mdt_attr 1 S 0 18794 1 0 75 0 - 0 - ? 00:00:00 ll_mdt_rdpg 1 S 0 18795 1 0 75 0 - 0 - ? 00:00:00 ll_mdt_rdpg Thanks, -Kums
