[Gluster-users] Thin Arbiter (was Gluster 7 or 8?)

[wkmail]

well, that is why I was asking.

Yes, we are extremely satisfied with the existing arbiter. It makes a 
measurable difference vs true Replica 3.

I was curious as to if Thin Arbiter was an *improvement* over regular 
Arbiter or even considered the new 'Arbiter' going forward.

The documentation indicates that Thin Arbiter is faster because we 
aren't waiting for the arbiter write to complete during full quorum ops.

However the doc's dont indicate if there is a safety cost over 
traditional arbiter, nor does it really say how much faster TA would be 
vs a traditional arbiter with an SSD/NVME sitting right next to the 
cluster on the same gluster network.

The docs do imply it was primarily designed for the out of band case you 
mentioned.

I was just curious if anyone had any real world experience and if it was 
considered stable and seems to work as advertised. I would so some 
testing on it.
