Hi guys,
Would appreciate some help. We currently have a FreeNAS server serving a RAID10 pool via NFS to 2 ESXi servers.
The pool consist of 4 WD Reds (2 vdevs). I've bought 4 more disks and would like to extend my pool.
Now I can see I'm able to do that via the volume manager, I can choose my additional 4 disks to extend my current setup, but I can see that I can choose either stripe or mirror.
If we are talking about virtualization storage, what would be the recommendation? if I choose to go for stripe this means I would have 4 mirrored vdevs right but would have the risk that if any of the vdevs die, it would destroy the pool?
The second question is regarding SLOG. We currently have sync writes disabled with all the risks involved. I've got 2x DC3700 SSDs that I would like to use as our SLOG device so I can enable sync writes and not worry about data loss in case of issues. If I've extended my pool, I understand from reading the forums that it would create another pool and just connect it to the volume. This means I would need to add an SLOG for each pool? If not, would it be a good idea to stripe/mirror them?
Thanks.
