Upgrade to WD30EFRX drives is failing
ReadyNAS Ultra 2 RAIDiator 4.2.30 (Latest) My old 3TB Seagates are failing so I am trying to replace them with WD WD30EFRX drives. The drives are supported according to the HCL (https://kb.netge...
Solutions to my original problem are spread out across multiple posts:
- Do a factory reset:
- I think using dd or hdparam is very useful:
- But I also feel the discovery I made was critical:
Thanks to all that helped out. Restore is complete and I have been running a couple of days now with the new drives. I even powered down to move the ReadyNAS into its permanent location.
Remember, the unit boots from the drives, not flash, unless the drives are empty. I suspect that the new unit booted into tech support mode because of something left over from the original installation in the old unit. When you complete the Data Lifeguard tests, delete all partitions from the drives before re-installing them (assuming they turn out OK).
The NAS boots off the flash for the early part of the boot process then switches onto the disks
Telnet can be active for a variety of reasons (only one of them is tech support mode but the other reasons put the NAS in a similar but slightly different state) including:
If you boot into tech support mode
If the NAS can't switch to booting off the disks for some reason (e.g. due to a bad disk, full 4GB root volume etc.) then it may start telnet and show an error in RAIDar about corrupt root or ERR: Used Disks Installed or something similar
When you do a factory reset during the 10 minute countdown (during which time you can abort the reset by powering down or proceed to wipe the disks by confirming you wish to do a factory reset) telnet is active, I think.
Most likely the RN212 detected a bad disk or couldn't switch to booting off the 4GB root volume. In any case we recommend moving disks from legacy x86 ReadyNAS to OS6 x86 ReadyNAS as if everything is fine with the disks and what's on them (it may not be) the OS6 x86 ReadyNAS can boot off the disks from the legacy x86 ReadyNAS. ARM OS6 ReadyNAS such as the RN212 cannot boot off disks taken from a legacy x86 ReadyNAS.
