    Description

      From time to time, KIT are seeing ldlm_cli_enqueue and ll_inode_revalidate_fini LustreError messages. They mainly appear on login nodes of our clusters.

      Here is an example of the error messages:
      Dec 17 10:24:28 ic2n988 kernel: [512992.139174] LustreError: 11865:0 (mdc_locks.c:840:mdc_enqueue()) ldlm_cli_enqueue: -13
      Dec 17 10:24:28 ic2n988 kernel: [512992.139183] LustreError: 11865:0:(mdc_locks.c:840:mdc_enqueue()) Skipped 2 previous similar messages
      Dec 17 10:24:28 ic2n988 kernel: [512992.139202] LustreError: 11865:0:(file.c:2716:ll_inode_revalidate_fini()) pfs2wor1: revalidate FID [0x1d080001:0x86b7421d:0x0] error: rc = -13
      Dec 17 10:24:28 ic2n988 kernel: [512992.139208] LustreError: 11865:0:(file.c:2716:ll_inode_revalidate_fini()) Skipped 2 previous similar messages
      Dec 17 10:24:29 ic2n988 kernel: [512993.347645] LustreError: 13000:0:(file.c:2716:ll_inode_revalidate_fini()) pfs2wor1: revalidate FID [0x1d080001:0x86b7421d:0x0] error: rc = -13

      The Lustre client in this case is at version 2.4.1 plus patch for LU-3645. The servers are also at version 2.4.1.

      What do the messages mean, and how can we get rid of these error messages?
