NAME
  sys_attrs_ufs - ufs subsystem attributes

DESCRIPTION
  This reference page lists and describes attributes for the UNIX File System
  (ufs) kernel subsystem. Refer to the sys_attrs(5) reference page for an
  introduction to the topic of kernel subsystem attributes.



  create-fastlinks (create_fastlinks)
      A value that enables (1) or disables (0) the creation of fast symbolic
      link files.

      Default value: 1 (enabled)



  inode-hash-size (inohsz)
      Size of (number of slots in) the inode hash chain table for the inode
      least recently used (LRU) cache.

      Default value: 2048 (slots)

      Minimum value: 64

      Maximum value:  16384

      Large inode hash chain tables spread the inode structures and may make
      chain lengths short.  This can reduce linear searches and improve
      lookup speeds.  In general, chains should contain only 2 or 3 elements.



  nmount (nmount)
      Obsolete.	 This attribute has been replaced by the vfs subsystem's
      max-ufs-mounts attribute, which is tunable at run time. See
      sys_attrs(5) for information about max-ufs-mounts.



  ufs-blkpref-lookbehind (ufs_blkpref_lookbehind)
      The range of blocks behind the current block location through which to
      search for a free block to allocate for an indirect block write
      operation (for all writes other than the first). A value greater than 1
      enables a look-behind search before writing each indirect block after
      the first block write operation.

      Default value: 16 (blocks)

      Minimum value: 1

      Maximum value: 64
