RAID0 is a bad idea, is this server for production use?

For video streaming actually ... i need a lot of storage that's why thinking about RAID-0 ...

go to rescue mode and type installimage and you can choose the OS you want...then it will open a configuration file there you can set the sw raid level and sw raid activation it's easy

Should i choose RAID-1 or RAID-5 instead of RAID-0 ?

Production use as in you care about the data, a single drive die out of the 4 and you loose the OS and all data on the 4 drives, at worst if you need the storage look at Raid 5 which would give you 12TB.

• RAID5 = 1 drive fault tolerance.
• RAID1 = you can't do with 4 drives.
• RAID0 = if 1 drive fails you lose all data.
• RAID10 = up to 2 drives can fail but depends, 1 drive minimum fault tolerance.

Thanks @Ishaq i'm gonna go with RAID-5 .... more storage , performance and security ...

When i am selecting RAID-5 i should have 66% of total storage but i am not getting 66% ... i think it's because of this

anyone have any idea about this ? do i need to change grub to anything else ?

StevenGeorge

anyone ?

Due to their installer not using GPT each partition can only be 2TB.

In the text file that launches you will need to create multiple partitions of 2TB, or use LVM (documented in the file)

Or you can mark the drives as GPT and then boot from a VNC CentOS installer from the robot interface and install as Raid5 with all disk space.

In the rescue interface do this for each drive (a,b,c,d) inplace of x

1/ parted /dev/sdx
2/ mklabel gpt (select y)
3/ q

Once this is done in the robot interface select the VNC Install for CentOS, this will provide you with an IP:PORT and password to connect to complete the install, during the CentOS select the do a manual drive setup and create your 4 Raid Partitions and then the Raid 5 devices as required.

Are you running a website on it? Video streaming sounds very interesting. What software solution are you using? I am just being curious . Let us know your website once you have it up and running
