Configurando Raid iMac

Tengo una configuration de 4ta unidad lacie 2big thunderbolt como raid 1. Quiero agregar una lacie 2big thunderbolt 4ta unidad. ¿Cómo lo configuro para que toda la unidad 1 se reproduzca en la unidad 2 (Raid1)?

A partir de El Capitán, la aplicación Disk Utility ya no brinda funcionalidad RAID, pero permanece en el progtwig de línea de command diskutil . Para get instrucciones breves, escriba diskutil appleRAID o diskutil appleRAID create en la terminal. Para get información más detallada, escriba man diskutil .

Lista de commands RAID disponibles:

 askewchan ~> diskutil appleRAID Usage: diskutil [quiet] appleRAID|AR <raidverb> <options>, where <raidverb> is as follows: list (Display the current status of RAID sets) create (Create a RAID set on multiple disks) delete (Delete an existing RAID set) repairMirror (Repair a damaged RAID mirror set) add (Add a spare or member disk to an existing RAID) remove (Remove a spare or member disk from an existing RAID) enable (Convert a volume into a single disk RAID set) update (Update the settings of an existing RAID) diskutil appleRAID <raidverb> with no options will provide help on that verb 

El command de create :

 askewchan ~> diskutil appleRAID create Usage: diskutil appleRAID create mirror|stripe|concat setName filesystemType MemberDeviceNames|NestedRAIDSetUUIDs ... Create a RAID set.

 askewchan ~> man diskutil DISKUTIL(8) BSD System Manager's Manual DISKUTIL(8) NAME diskutil -- modify, verify and repair local disks SYNOPSIS diskutil [quiet] verb [options] DESCRIPTION diskutil manipulates the structure of local disks. It provides information about, and allows the administration of, the partitioning schemes, layouts, and formats of disks. This includes hard disks, solid state disks, optical discs, CoreStorage volumes, and AppleRAID sets. It generally manipulates whole vol- umes instead of individual files and directories. 

En RAID:

 appleRAID | ar raidVerb [...] AppleRAID verbs can be used to create, manipulate and destroy AppleRAID volumes (Software RAID). AppleRAID supports three basic types of RAID sets: o "stripe" - Striped Volume (RAID 0) o "mirror" - Mirronetworking Volume (RAID 1) o "concat" - Concatenated Volume (Spanning) Of these three basic types, only the "mirror" type increases fault- tolerance. Mirrors may have more than two disks to further increase their fault-tolerance. Striped and concatentated volumes are, in fact, more vulnerable to faults than single disk volumes. AppleRAID is not a replacement for backing up your data. Backups should be always be performed on a regular basis and before modify- ing any RAID set using these commands. 

Al crear un nuevo RAID:

  create mirror | stripe | concat setName format devices ... Create a new RAID set consisting of multiple disks and/or RAID sets. setName is used for both the name of the cre- ated RAID volume and the RAID set itself (as displayed in list). eg 'diskutil createRAID stripe MyArray JHFS+ disk1 disk2 disk3 disk4'. Ownership of the affected disks is requinetworking. diskutil createRAID is a deprecated synonym for diskutil appleRAID create. 

Fácil, el progtwig Disk Utility en OS X permite la creación de software RAID.

  • Open Disk Utility de Spotlight o / Aplicaciones / Utilidades
  • Escriba "Crear RAID" en el término de búsqueda del menu de ayuda
  • Vaya al artículo y siga los pasos para Crear un set RAID duplicado

Esto implica borrar todas las unidades, por lo que querrá asegurarse de que todo esté respaldado en otro lugar antes de comenzar. El 10.11 de El Capitán, esta function de la herramienta gráfica Disk Utility se eliminó, por lo que necesitaría llamar al command diskutil subyacente que todavía tiene los commands RAID.
