It looks like your getting a 3TB stripe and a 1TB stripe which is expected to use all the space. I think this is your problem: [2012/03/29 21:38:06 2104] LINE 448: exec command: echo "DOING_F_RESIZE" > /.os_V_E_continue [2012/03/29 21:38:06 2104] LINE 4249: exec command: resize2fs -pf /dev/c/c resize2fs 1.42.1 (17-Feb-2012) resize2fs: New size too large to be expressed in 32 bits [2012/03/29 21:38:06 2104] Expand second phase error 10: resize2fs, err=0x100 [2012/03/29 21:38:06 2104] File system expand failed It's having trouble adding the last 3TB to the 3TB stripe. I thought the capacity you are trying to do was supported, but maybe it's coded to do some special layout that is not kicking in for the unsupported 4TB disks. I've got 4TB disks in mine too, but not at this high a capacity so I'd like to understand this too. steve

Some generic linux info about this here: http://blog.ronnyegner-consulting.de/20 ... ow-solved/

Seems that resize2fs doesn't support crossing the 16TB boundary. So you need the >16TB filesystem created from the start unless netgear has some other fix that became available recently, but resize2fs is giving the error so it appears not. I'm not sure why the NAS is doing this in two steps instead of one. Maybe a Jedi can explain. Is it possible you've tried two drives in slot 6 that might have issues?
