I’m going to add a RAID 1 of two M.2 NVME drives to my second NAS. It is currently set up with 6 drives in RAID 5.
How can I make the M.2 drives the first storage group? Shut down the NAS, add the M.2 drives, remove the hard drives, boot NAS. Create new storage group with the M.2 drives. Shut down NAS. Reinsert hard drives. Start NAS.
Will that do it?
Yeh as long as you dont care about data on the 6 raid 5 drives.
So this will destory the RAID i currently have now? How then can you add the SSDs as the first storage group without a complete rebuild? Or cant you?
OS and NAS setup is already on the raid5 portion on each drive. If you put a set of the NVMe drives in and then set those up it would be a complete new setup with no knowledge of the existing setup so it would see the other 6 drives as new drives.
I might be wrong so hopefully someone else can maybe chime in but I am pretty sure this is basically how it worked when I did something like this in the past. I didnt try to recover my RAID group though.
So you are trying to make the NVMe’s your system volunm/pool? (No OS was mentioned)
As your HDDs currently contain the system volume/pool, that need to be removed first.
Yes. OS is Hero.
So basically i need to rebuild everything in order to do this. Or i could just install the drives as another storage group and move all my applications there.
You need to remove the current system pool though (otherwise you cannot create a new one)
Since creating a new system pool requires starting over from scratch, it is too much work. Instead i was saying then that i can just create a new storage pool with the SSDs and move my app installs there.
You can put apps in any storage group.
What advantage really does having the system pool being SSD give you since the OS is spread everywhere and apps can be installed anywhere.
Some apps cannot be moved and can only be installed on the system pool, it depends on the app
OK. Well, I am not too worried about it. The main reason for adding these is for virtual machines. If I can’t move certain apps to that storage group then oh well. If the would reside only on the SSD drives, then that would be a different story. But it doesn’t and is limited anyhow by the speed of the slowest drive.
Well, shoot! Virtualization Station is one of the apps that can’t be migrated off the system volume. While I can store the VMs on the flash drives, I’m trying to maximize speed here. Maybe it is worth restarting from scratch…
