Instability with 2.2.2 and znapzend operations (resolved)

[xenophon]

Hi, and thanks for a great project.

I've implemented a znapzend setup between two OS X computers, for daily backup. The setup is detailed here: https://github.com/xenophon61/Znapzend-recipes-for-mixed-MacOS-Linux-environment

To make a long story short, there has been HUGE instability on the receiving machine (both running OpenZFSonOSX 2.2.2) during

Code: Select all

zfs recv -F

operations (which is the way znapzend transfers data betweeen source and target).

Downgrading to 2.2.0 resolved all issues! Note that one has to use the "trigger-panic-medic" procedure for downgrade.

The hangs, GUI freezing and "watchdog" kernel panics disappeared! Very happy with the result, but I guess it may be helpful to research this issue, in view of the upcoming 2.2.3 release. If interested, please take the time to go through the wiki from the link above.

Take care, and thanks for all the work put in this amazing project. With greetings from Athens,

Xen
