I know this is not exactly a Linux question but i have just built a freenas
server with 8 gigs of ram and 2 x 3TB NAS HDDs however i have also filled
it and need to look at buying two more drives should i keep it mirror and
snapshots or should i use raidz 2
How is it set up now? I assume its a RAID1 cos ZFS requires three (?) disks
If you add drives to a RAID1 you just get spares, not more space.
So you'll create a second RAID1 and have a second mountpoint.
If you want to go ZFS then you'll need a temporary location to store any
existing files, while you recreate the storage.
What do you use it for?
Important files vs large misc files vs some backend storage for a VM
server ?
Also, you may need more memory for ZFS - again I recall the rule of
thumb is recommended 1GB ram per 1TB disk.
