I’ve been running an EX4100 with 2x 1TB HD’s in RAID 1 with no problems.
Couple of days ago I added a further 2x 4TB HD’s. Also set these up in RAID 1 as Volume 2 but after the setup was complete the capacity was showing 0.
Tried again with RAID 0,1,5 & 10 - all with the same result. Smartware depicts the unit with “no writable partition found”.
If I setup the unit as JBOD then I get full 10TB capacity but really want to be operating in RAID 1 for to protect the data.
