Marshalleq Posted June 22, 2019 Share Posted June 22, 2019 Has anyone done this? I'm thinking about setting one up. I'm not sure yet how I'd make it persistent, but assuming I can it would be great for VM's and docker I think. Quote Link to comment

Not sure what you mean by mirror, but for VM's and docker you can use a cache drive, or install unassigned devices plugin and mount a drive for VM's and docker. Quote Link to comment
Marshalleq Posted June 22, 2019 Author Share Posted June 22, 2019 Yes, I'm aware - I posted about this elsewhere but no reply cause I gave too much detail I don't want to use my existing cache drive (BTRFS Raid-1), the SSD endurance won't handle the VM's and dockers I have which are constant IO. I had one in unassigned devices (enterprise grade 1TB Samsung), but it died. So I thought how can I get redundant SSD's without having to sell / throw away my current cache drives which are perfectly good? So I figure an additional standard Raid-1 Mirror, which somehow I have to mount in Unraid, since unraid doesn't as far as I know provide this capability through the GUI. Quote Link to comment

Are you talking about getting another SSD to implement this mirror? If so there are forum posts about how to create a BTRFS RAID1 style mirror from the command line and then mounting this under Unassigned Devices. I have not done this myself but as I understand it, it is only the creation stage that needs to be done from the command line and once created Unassigned Devices can handle the mounting/unmounting.

Marshalleq Posted June 23, 2019 Author Share Posted June 23, 2019 Oh fantastic! That's exactly what I was looking for, thanks for the tip! Quote Link to comment
bonienl Posted June 23, 2019 Share Posted June 23, 2019 It is also possible to set up a cache pool as BTRFS RAID1. This is supported from the GUI. I have 4 SSDs in the cache pool set up as RAID10 (to have redundancy and performance boost) Quote Link to comment
Marshalleq Posted June 23, 2019 Author Share Posted June 23, 2019 Thanks, I have BTRFS Raid1 Cache already, this is additional. Quote Link to comment
