Hello Dell And others,

 

Good Day.

 

I know this is a low brainer but I appreciate any feedback.

This is about Raid Array having hot spares.

1. Raid 1 (Mirroring)

Does raid 1 need hot spare to perform fault tolerance?

 

2. Raid 10 (Stripe and Mirror)

For Example, I have 4 SAS Drives configured in Raid 10, Does This one also need a hot spare to perform HA?

 

3. Raid 5 (Striping)

I Have 3 HDD (600 GB Each) configured in Raid 5 with a logical volume capacity around 1.2 TB.

Do I need to have a hot spare for this one in order for the parity to perform HA?

 

I Hope you can help me with my confusions.

 

Thanks a lot!
