ReadyNAS Ultra6 Plus - no expansion with new drives
System updated to RAIDiator 4.2.22, encountered issue when attempting to set up using 2 WD10EALX drives (1TB), swapped to 2 WD10EARX-00N0YB0 (1TB). OS loaded and running, added 1 of the WD10EALX drives and expansion occurred normally. Attempted to add 2nd WD10EALX drive, recognized by system, status OK, visible in the Volumes --> Volume Settings page as an available disk, but expansion not triggered. Added another WD10EARX drive, same thing. Have SSH access loaded and looking at logs, however zero information appears in the GUI or logs that indicates why the XRAID2 will not expand.
What additional troubleshooting or commands can be done to trigger expansion or debug why the drives are not being added to the XRAID volume? Drives have been validated and are not showing errors in SMART diagnostics, and have been in use without issues as both VMFS datastores in ESX hosts and as iSCSI target LUNs under Windows 2008 R2 Server. I realize that the EALX drives are not on the HCL, but if they are being rejected for that reason, the GUI or logs should report an error. Failure to do so is bad GUI design.
Suggestions? So far performance on my 3-drive setup is very nice, and having RAID instead of single volumes in my lab environment is a warm fuzzy. Just want to understand why additional hardware is not being picked up.
You can try support, but they might not help since the ealx isn't on the HCL.
One standard answer (if all else fails) is to backup up your data and config and try a factory default with all disks in place.
Though there is an offline expansion procedure posted here: https://www.readynas.com/forum/viewtopi ... 12#p353102 If you are at the point of trying a factory a default anyway, there is no harm in trying it (since you have the backups already, and if it does damage you'd be doing the factory default anyway).
