I apologize in advance if my question has been answered in some form before, or is not located in the correct section.
The problem I am trying to solve is that, I have an old Supermicro chassis with AMD Opteron processor, and this CPU does not support SSSE3 instructions. That is a major problem for 3 or more parity drives, as SnapRaid uses it to accelerate calculation. At the moment my system with 20 Data drives and 4 parity HDDs takes 4 days to do scrubs etc...
There is one option for poor schmucks like me, that is to get down to 3 parity drives, and select "z-parity" for the 3rd drive. This "z-parity" option was added in SnapRaid for old CPUs to accelerate 3 parity drive calculation.
I have not seen this option available on the OMV SnapRaid plugin, maybe I missed it, but I am sure that would be a bit of a headache to implement only to support ancient hardware. Although I wouldn't complain if someone as this to the plug-in.
So my question is: how can I go about to modify snapraid.conf without making a mess with the plug-in database? And make sure my change won't be reverted by OMV behind my back?
