How many drives do I need for RAID 1?
two drives
A minimum of two drives is required for RAID 1: one drive for the user data, and one drive for the mirrored data. If you select four or more drives, RAID 10 is automatically configured across the volume group: two drives for user data, and two drives for the mirrored data.
How many disks can be used for RAID 1?
two disks
RAID 1 can be implemented through either software or hardware. A minimum of two disks is required for RAID 1 hardware implementations. With software RAID 1, instead of two physical disks, data can be mirrored between volumes on a single disk.
What happens when a RAID 0 drive fails?
When a RAID 0 volume fails or is disconnected, the data on the hard drive is no longer accessible. If a hard drive is disconnected, you may be able to recover the volume. If a hard drive fails, you cannot recover the data.
Can a standard controller read a RAID 1 disk?
Thanks for your feedback! Usually with RAID1 you can connect a single disk to a standard controller and read it normally. I know it works for RAID1 arrays created by Intel, LSI, and Dell controllers at least.
Can You Mount / Dev / Md0 in RAID 1?
Then you can mount /dev/md0 (or, if it is actually LVM, etc., continue down the chain). You can, in the case of RAID1, also do this using loopback devices & an offset, but that’s much more of a pain, and really is only worth attempting if the mdadm metadata has been destroyed.
What are the names of the raid partitions?
In the case above, sp:0 and sp:1 I believe are what I named the RAID partitions at the time of creation. From a new system that had never had an array before with the two drives attached externally via USB drive dock:
