Hi!

I'm new to NexentaStor and need some help. Hope someone can help me as I can find any help on these issues eventhough I have been Googling a lot.

My setup:

Adaptec Controller with 10 x SATA 2 Tb disks and 2 x SSD 128 Gb disks.
LSI adapter with 4 x 146 Gb 10k SAS disks.
Xeon processor and 32 Gb RAM. 4 x 1 Gbit/s Network adapters

Right now I'm booting on a USB stick. But that is kind of slow. I want to do the following, is it possible ? and how do I do it ?

Mirror the 2 SSD disks. Install Nexenta on a X Gb partition.
Since I want ZIL log for both the 10 x SATA 2 Tb RAID-Z2 volume and the 4 x SAS 146 Gb RAID-Z1 volume, can I further partition (splice ?) the mirrored 2 x SSD disks ?

If yes, how can I do it ? Or should I do it some way else ?

Any help would be appreciated....

My goal is to use the 10 x SATA disks storage for video editing and the 4 x SAS disks for a VMFS datastore for my virtual machines (LAB)
 
I've never done this specific situation before but would re-install the OS on to the SSD using the installation tools to slice up the disk how you would like it.

Then after you have a working system you slice up your other SSD exactly the same, and then add them together with the zpool attach command.
 
Hi Staticlag,

Do you think it's possible ? How do I slice up the SSD disks during installation ?
I don't recall to have seen any options during install ?

Can you help ?
 
Whilst it is possible is a bad hack and very not recommended. Two small spinning disks mirrored for the OS are the best idea.
 
A few things
1. CE only supports 18TB raw disk if I'm not mistaken
2. Using SSD for boot is a waste
3. When you partition SSD, make sure you align it properly

Not sure about Nextenta, but others do allow you to use partition instead whole disk during installation. One way to deal with it is to use some live CD to boot and manually partition the SSD then install Nexenta on it.
