Incompatible Block Sizes for raid on HPE DL 20 plus GEN10 server
Good morning, I have a problem with an HPE DL 20 PLUS GEN 10 server

I want to create a RAID 5 with four hard drives, using INTEL VROC and it tells me that it has Incompatible Block Sizes.

Any solution?

Hello,

Please refer to the general and specific user guides for Intel VROC at the Intel support page and see if they help.

Hi @casimiroleal11 ,
    Suprisingly, I didn't find the word 'Block size' in VROC documents, but I assume block size is called as Strip size in Intel VROC RAID controller.
    It must be 64KB for RAID 5.  Refer this HPE document. 

I hope, my post helps you, if yes, please give 'Kudos' and mark my post as 'Accepted solution'

Buenos dias, comparto fografias de mi caso. 

Cordial saludo desde Colombia

El servidor es un HPE DL20 GEN10 Plus con controladora Intel VROC RAID

Busco hacer un arreglo RAID 5 con un total de 4 discos duros. Dos de ellos son 512E y los otros dos son 4KN. Al intentarlo hacer el arreglo me dice: incompatible Block Sizes

Comparto fotografías de los discos y de cómo se ve al intentar hacer los arreglos.

Por favor ayuda!

The server is an HPE DL20 GEN10 Plus with Intel VROC RAID controller

I am looking to make a RAID 5 array with a total of 4 hard drives. Two of them are 512E and the other two are 4KN. When I try to make the array it says: incompatible Block Sizes

I am sharing photos of the drives and how it looks when I try to make the arrays.

Hi @casimiroleal11 ,

No he trabajado mucho en el controlador VROC. Probemos lo que entendí:
1) Seleccione solo los discos del puerto 4 y el puerto 5, mantenga el tamaño de la banda en 64 KB y cree RAID 0 o 1
2) Seleccione solo los discos del puerto 6 y el puerto 7, mantenga el tamaño de la banda en 64 KB y cree RAID 0 o 1
Resultado:
a) Si ambos niveles RAID se crean correctamente, concluimos que la creación de RAID con los 4 RAID no funcionará debido a que los discos son diferentes.
b) Si solo se crea un nivel RAID, entonces solo esos discos son compatibles para crear RAID en VROC.

Si alguno de los RAID funciona bien, entonces debe comprar el mismo disco, insertarlo y crear RAID 5.

English : 
Let's test as what I understood,
1) Select only port 4 and port 5 disks, keep strip size to 64KB and create RAID 0 or 1
2) Select only port 6 and port 7 disks, keep strip size to 64KB and create RAID 0 or 1
Result :
a) If both RAID levels are created successfully, then we conclude, creating RAID with all 4 RAIDs will not work due to Disks are different.
b) If only one RAID level is created, then only those disks are compatible to create RAID in VROC.

If any one of the RAID is working fine, then, you need to purchase the same disk, insert and create RAID 5.
