Document Affected: "NFS Parameters for the nfs Module" in System Administration Guide, Volume 3 (4299091)

Several corrections apply to this section:

• For the nfs_32_time_ok symbol:

  • Change the symbol name to: nfs_allow_preepoch_time.

  • Change the description to: This symbol controls whether the NFS client or server allows file time stamps that precede 1970.

  • No change to the default description.

  • Delete the nfs_acl_cache symbol entry.

• Add an nfs_disable_rddir_cache symbol entry.

  • Description: Some servers do not properly update the attributes of the directory when changes are made. To allow interoperability with these broken servers, set this variable to disable the readdir cache.

  • Default: Set to off(0).

• For the nfs_lookup_neg_cache and nfs3_lookup_neg_cache symbols:

  • Change the default to 1. Ignore the comment about the directory name caching.

• For the nrnode symbol:

  • Change the default description to: set to ncsize. By setting the variable to 1 you are effectively disabling the cache, not because there is an explicit check to see whether or not it is 1 but because you are creating a very small cache.

• For the nfs_write_error_interval symbol:

  • Change the description: This symbol controls how often NFS ENOSPC and EDQUOT write error messages are logged. Its units are in seconds.

  • No change to the default description.
