Faire un RAID

[fxn]

Je vais devoir ré-assembler 4 HD en RAID (Vitesse)

il me semble que l'on ne peut plus faire le RAID par Utilitaire de Disque ( ou je me trompe ?)

Donc je suppose une solution autre ? un logiciel tiers ?

lequel ?

en vous remerciant

[ch21]

Cette possibilité a été supprimée il y a pas mal de temps il me semble, genre Yosemite.

Il reste toujours le Terminal pour faire ça.

C'est pas vraiment glop mais dans le Terminal, tu tape : "man diskutil"
et tu auras ça :

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" - Mirrored 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 fur-
                ther increase their fault-tolerance.  Striped and concaten-
                tated volumes are, in fact, more vulnerable to faults than
                single disk volumes.

                From these basic types, "stacked" or "nested" RAID volumes can
                be created.  Stacked RAID sets that make use of mirrored RAID
                sets are fault-tolerant.  For example, these are some of the
                more common combinations of stacked RAID sets:

                      o   RAID 50 - A striped RAID set of hardware RAID 5
                          disks.

                      o   RAID 10 - A striped RAID set of mirrored RAID sets.

                      o   RAID 0+1 - A mirrored RAID set of striped RAID sets.

                      o   Concatenated Mirror - A concatenation of mirrored
                          RAID sets.

                When creating new RAID sets or adding disks, if possible, it
                is better to specify the entire disk instead of a partition on
                that disk.  This allows the software to reformat the entire
                disk using the most current partition layouts.  When using
                whole disks, the type of partitioning used is selected based
                on the platform type (PPC = APMFormat, Intel = GPTFormat).
                GPT and APM partition formats cannot be mixed in the same RAID
                set.

                In addition to whole disk and partition device names,
                AppleRAID uses UUIDs to refer to existing RAID sets and their
                members.  Existing RAID sets may also be specified by mount
                point (e.g.  /Volume/raidset). In many cases, using the UUID
                for the device argument is preferred because disk device names
                may change over time when disks are added, disks are removed
                or when the system is rebooted.  If RAID members have been
                physically disconnected from the system or are no longer
                responding, you must use the member's UUID as the command
                argument.  Messages in the system log will refer to RAID sets
                and their member disks by UUID.  For more information on spec-
                ifying device arguments see the "DEVICES" section below.

                AppleRAID is not a replacement for backing up your data.
                Backups should be always be performed on a regular basis and
                before modifying any RAID set using these commands.

                The following is a list of appleRAID sub-verbs with their
                descriptions and individual arguments.

etc…

Puis après, des exemples.

Pour t'entrainer le mieux c'est de tester avec des clés USB.
enfin c'est ce que j'ai fait pour comprendre un peu mieux, n'étant pas très doué
