Hi all,
I am currently using unraid for about a year, and now going to add some disks (now having 1 8TB parity + 1 8TB array) to it, and since now unraid supports zfs, so now i wish to have zfs format.
Now here my situation:
1. I am going to add 4 x 8TB disk.
2. I am going to setup it as a zfs pool with raidz.
So my question is:
1. Since raidz provides a similar function as parity, do I still need parity drive?
2. If yes, based on my research, parity must be the largest or equal space disk, so if i setup a disk pool (in this case it will be 8tbx3 = 24tb), does this make sense?
3. My previous 8TB drive, most of resources are jellyfin media, would it be nice if i reformat all to zfs, and create a raidz, without the parity?
4. Currently i having an issue with write speed, if with parity drive, my write speed from other computer to unraid will be limited to 70mb/s +- (1gbps lan network), but previously there is no speed limit before i added parity drive. Is this caused by parity?
Sorry for my poor knowledge, i really cant decide what to do now. I wonder if there is some mistake, i have to take a long time to do data migration. Hope that some pros could give me a good solution.
Thanks in advance.
