Member(s) with diskutil appleRAID remove. The newĭisk must be the same size or larger than the existing disks in the RAID set.Īfter running this command, you should manually remove the old (orphaned, failed) Mirror set whose exported disk device or set UUID is given as raidVolume. Repair a degraded mirror by adding a 'new' disk given as newDevice to the RAID Own-ership OwnershipĮrship of the affected disks is required.

For more information on specifying device arguments see the 'DEVICES' section below.ĪppleRAID is not a replacement for backing up your data. Messages in the system log will refer to RAID sets and their member disks by If RAID members have been physically disconnectedįrom the system or are no longer responding, you must use the member's UUID as the commandĪrgument. In many cases, using the UUID for the device argument is pre-ferred preferredįerred because disk device names may change over time when disks are added, disks are Existing RAID sets may also be specified by mount In addition to whole disk and partition device names, AppleRAID uses UUIDs to refer toĮxisting RAID sets and their members. GPT and APM partition formats cannot be mixed in the same RAID set. Tioning used is selected based on the platform type (PPC = APMFormat, Intel = GPTFormat).

This allows the software to reformat the entireĭisk using the most current partition layouts. When creating new RAID sets or adding disks, if possible, it is better to specify the entireĭisk instead of a partition on that disk. Concatenated Mirror - A concatenation of mirrored RAID sets.RAID 0+1 - A mirrored RAID set of striped RAID sets.RAID 10 - A striped RAID set of mirrored RAID sets.RAID 50 - A striped RAID set of hardware RAID 5 disks.The more common combinations of stacked RAID sets: Sets that make use of mirrored RAID sets are fault-tolerant. Tated volumes are, in fact, more vulnerable to faults than single disk volumes.įrom these basic types, 'stacked' or 'nested' RAID volumes can be created. Have more than two disks to further increase their fault-tolerance. Of these three basic types, only the 'mirror' type increases fault-tolerance. 'concat' - Concatenated Volume (Spanning).AppleRAID supports three basic types of RAID sets: AppleRAID verbs can be used to create, manipulate and destroy AppleRAID volumes (Software
