SOLVED how to check what RAID is used?

[dirkme]

I know it sounds silly, I might have already the answer, but need to have some knowledgeable person telling me to confirm ;-)

Thanks a lot for all your help ;-)

What's an rtaid?

finders keepers, it is yours, now you can miss spell raid for the rest of your life.

First, some terminology: What you're looking for is the pool's layout.

That is easily obtained by looking at the relevant section of the GUI or by running zpool status.

zpool status (in terminal), didn't let me know what raid is used like z1 or z5, I found a z1 on the FreeNAS interface at volumes.

There it says: raidz1-0 (0 is most-likely the first disk)

You should have seen raidz1-0 listed when you issued the zpool status command.

the "-0" designation is for your first vdev. A pool can be composed of one or more vdev's. The second one would have a "-1" and so on.

Please post your results from zpool status in code tags.

Oh, now I see it (embarrassing)

Does that mean it is 4 drives mirrored instead of raid 5 (3 drives for space and 1 for redundancy)

 

[CraigD]

Not mirrored, you have a single drive failure tolerance

Have Fun

Thanks a lot, I was afraid I had them mirrored.

How come it says z1, shouldn't it say z5?

 

[CraigD]

The number after the z is the number of drive that can fail without data loss

 

[dirkme]

Wow, thanks a lot, I didn't know this.

Thanks a lot :)

...and there is no such thing as RAIDZ5. You're thinking of RAID5, which is kind of similar, but fundamentally different.

Not yet but I'm sure it will in the next 3 years

The new parity de-clustered ZFS RAID is really weird. It's being called DRAID in some of the preliminary documentation. Don't know what it will be called when it's finally released.
