Hello all,
tomorrow I'll get an HP Microserver Gen8 wiht 4x1TB HDD to which I would like to migrate 1.99TB of data from a Synology with 2x3TB HDD (In SHR "RAID1")
My plan is:
Create ZFS Pool as follow
VDEV Mirror 1
> disk1 -1TB + disk2-1TB
VDEV Mirror 2
> disk3 - 1TB + disk 4-1TB
Migrate 1.99 TB of data (I can reduce migration by scarifying some data if necessary) to the ZFS POOL.
Then, the plan is to take 1 of the 3TB HDD from the Synology and replace one disk in the pool:
VDEV Mirror 1
> - disk1 -3TB + disk2-1TB
VDEV Mirror 2
> disk3 - 1TB + disk 4-1TB
Once resilvering is done I'll take the second 3 TB HDD and change the pool as follow:
VDEV Mirror 1
> - disk1 -3TB + disk2-3TB
VDEV Mirror 2
> - disk3 - 1TB + disk 4-1TB
After resilvering I will exand the pool and I should then end up with a total storage of about 4TB with the option to increase the Pool later one by replacing the disks in the VDEV Mirror 2
I'm choosing Mirroring vs RAIDZ1 as this will be used mainly as a streaming server so I'd like fast reads and as well to make it easier to increase storage in the future. Of this migration strategy I like the fact that in case things go wrong I will still have my data on one of the 3TB drive in the Synology so seems pretty safe to me... but I'd like to know from the experts :D
