Hi,
I have been doing some benchmarking on my Dell R720. I can clearly see the massive difference a ZIL drive makes when using NFS shares vs iSCSI.
I have 2 pools that I would ideally include a zil in. But I have no space to add two separate SSDs in the server. So I have 1 SSD that I could use as a ZIL.
The question is: is it even ok to do that? what are the pitfalls? If it's 'OK' to do it, then how to do it?
I added the zil by:
As I mentioned above, I added one SSD to my stripped mirror 2 x 2 pool running SAS hard drives. I would love to partition it and add the other half of this SSD to the second 2 x 2 pool so that I could use sync=always (because the second pool is hosting proxmox VMs and the first pool is running Postgres DB)
Many thanks
