HDD Config

[glenb83]

Hi Guys,

Just wanted to check my hdd config is right before I switch from Freenas to Amahi.

I currently have 4x 2TB hdd's in a ZFS array and Freenas running on a USB stick. My plan is to backup all the data to an external hard drive, then format the 4x 2TB hard drives ready for the Amahi install.

I then want to install Ubuntu + Amahi to one of those drives and use the rest of that drive plus the other 3 as a greyhole storage pool. Am I best to create a 'system' partition on 1 of the drives with enough space for Ubuntu/Amahi and plugins with room for any additional system files etc (recommended total size?) then create another partition with the remaining drive space of that disk and add that to a storage pool with the 3x other drives? I basically just want as much storage as possible with redundancy for all my data.

If there is a better way I am open to suggestion.

Thanks!

Having your system drive store data is up to you, but I would suggest against it.

For system drive, you need roughly...

16GB for /
300MB for /boot
4GB for swap
8GB for /home (or however much you would think to need.

then for landing zone, you need
1 to 2 TB for /var/hda/files

and then if you're using greyhole for storage pooling and per-folder redundancy, then you can just calculate the total storage you need for your data with single duplication eg:
1.5TB x 2 = 3TB of total drive space needed to store your files and duplicate once.
that would leave your drives to be each at...
/var/hda/files/drives/drive0
/var/hda/files/drives/drive1
/var/hda/files/drives/drive2

I think you can work from there.... get the picture?

Sorry to seem ignorant, but just to be sure....

With 4x 2TB hard drives, the configuration should be something like:
Drive 0 - System drive (e.g. /, /boot, swap, /home) & Landing Zone. (Should it be 2x partitions to separate the landing zone from 'system' or is that not necessary?)
Drive 1, 2, 3 - storage pool with redundancy

Not necessary to separate the landing zone from the OS, but that's personal preference. Your hard drive setup pretty much matches mine. I have been using it this way for years.
