NFS overprovisioning of 0.5 ???
Hi.
wondering if it is possible to set overprovisioning factor to less than 1 ?
I have 1 NFS box, 2 x 10GB cards inside, don't want to do bonding, but
efectively present this single box as 2 boxes via 2 IP adresses - so in
this scenario I need to set overprovisioning factor to less than 1, to i.e.
0.5 - because of disk space etc...
This is for test purposes, but again...

Hi, my instinct says it won't work, but there shouldn't be any harm in
trying. IIRC some settings like this have to be >= 1. However, the
storage disable thresholds seem more appropriate for this scenario. You
can set it at various levels (global, zone, cluster) depending on your
exact needs.
Best regards,

true... ZFS pool under NFS...will consider...but I;'m just wondering, since
it is math of available space = overprovisioningFactor x realspace - I
guess this is technicaly possible...

I think your approaching this from the wrong side.
Why not just nfs export half of the space instead? (you could use lvm, thin-lvm etc)?
