  45. .Sh DESCRIPTION
  46. Splits devices off
  47. .Ar pool
  48. creating
  49. .Ar newpool .
  50. All vdevs in
  51. .Ar pool
  52. must be mirrors and the pool must not be in the process of resilvering.
  53. At the time of the split,
  54. .Ar newpool
  55. will be a replica of
  56. .Ar pool .
  57. By default, the
  58. last device in each mirror is split from
  59. .Ar pool
  60. to create
  61. .Ar newpool .
  62. .Pp
  63. The optional device specification causes the specified device(s) to be
  64. included in the new
  65. .Ar pool
  66. and, should any devices remain unspecified,
  67. the last device in each mirror is used as would be by default.
  68. .Bl -tag -width Ds
  69. .It Fl g
  70. Display vdev GUIDs instead of the normal device names.
  71. These GUIDs can be used in place of device names for the zpool
  72. detach/offline/remove/replace commands.
  73. .It Fl L
  74. Display real paths for vdevs resolving all symbolic links.
  75. This can be used to look up the current block device name regardless of the
  76. .Pa /dev/disk/
  77. path used to open it.
  78. .It Fl l
  79. Indicates that this command will request encryption keys for all encrypted
  80. datasets it attempts to mount as it is bringing the new pool online.
  81. Note that if any datasets have
  82. .Sy keylocation Ns = Ns Sy prompt ,
  83. this command will block waiting for the keys to be entered.
  84. Without this flag, encrypted datasets will be left unavailable until the keys
  85. are loaded.
  86. .It Fl n
  87. Do a dry-run
  88. .Pq Qq No-op
  89. split: do not actually perform it.
  90. Print out the expected configuration of
  91. .Ar newpool .
  92. .It Fl P
  93. Display full paths for vdevs instead of only the last component of
  94. the path.
  95. This can be used in conjunction with the
  96. .Fl L
  97. flag.
  98. .It Fl o Ar property Ns = Ns Ar value
  99. Sets the specified property for
  100. .Ar newpool .
  101. See the
  102. .Xr zpoolprops 7
  103. manual page for more information on the available pool properties.
  104. .It Fl R Ar root
  105. Set
  106. .Sy altroot
  107. for
  108. .Ar newpool
  109. to
  110. .Ar root
  111. and automatically import it.
