Dear Community,
i need your help :)
I just FreeNAS for more than 6 month and everything went fine.
No I did 2 changes and ran into a bigger problem:
1. Change: I removed my SSD cache (because it didnt really increase the speed) and added it as ZFS Volume
2. Change: I added another external storage (identical to the one i already used) in order to increase the storage.
System Setup:
FreeNAS-9.2.1.8-RELEASE-x64 (e625626)
i3-4010U CPU @ 1.70GHz
8 GB RAM
30GB SSD (ada0)
8TB external RAID Station (now two of them) via USB3.0 (da1, da2)
I had to set hw.usb.no_shutdown_wait to 1, due to the trouble of external storage but that shouldnt effect us here.
So, now after a reboot I retrieve the following error, if I want to attach the first encrypted volume, i justed the last 6 month:
In parallel I get a new option within the storage tab "view multipaths" with (da0)
My Question: what happened after I plugged in the additional storage ?
How can I handle this problem?
Maybe freenas detected those two external storage as multipath falsely . Is there a way to "remove" this multipath and let freenas interprets both connections individual?
Thank you and best regards

FreeNAS® uses gmultipath(8) to provide multipath I/O support on systems containing hardware that is capable of multipath. An example would be a dual SAS expander backplane in the chassis or an external JBOD.
Multipath hardware adds fault tolerance to a NAS as the data is still available even if one disk I/O path has a failure.
FreeNAS® automatically detects active/active and active/passive multipath-capable hardware. Any multipath-capable devices that are detected will be placed in multipath units with the parent devices hidden. The configuration will be displayed in Storage ‣ Volumes ‣ View Multipaths. Note that this option will not be displayed in the Storage ‣ Volumes tree on systems that do not contain multipath-capable hardware.
Thank you and best regards
