ReadyNAS 2120 - no volumes found
ReadyNAS 2120 v2 is showing "no volumes found" after replacing drive 1 and a successful resync. a few hrs later (3am) drive 4 failed. We arrived in the morning to see the red light on drive 4, then accessed the NAS via web browser... the red light turned off and a "no volumes found" message appeared.
rebooted, same.
shut down, reseated all drives, power on, same.
Bought support (1yr $150), contacted support, they didn't look at anything just said to buy a new NAS...
Looking for a direction to go now, these forums seem to have better support then the paid contract support - as you at least ask for the logs before saying "buy a new product from us..."

It doesn't sound like a chassis hardware problem to me. You say there was a "successful re-sync". How long after the drive we replaced was that? And have you ever vertically expanded the volume (put in larger drives)? Unfortunately, the ReadyNAS will sometimes confuse you into thinking the volume sync is complete, but it's either only reporting the OS partition is in sync (which only takes a few minutes) or that one of two RAID layers of an expanded volume is in sync. If the second failure occurred before the data volume was actually fully in sync, that's the cause of the issue.
I suggest you test the hardware using a spare drive containing no data you care about. Install just it in the NAS and create a volume (you may need to format it first if it's got data on it from a precious use). If that works, then power down and swap the drive to the next bay. Continue through all four.
Thanks for the ping, StephenB!
Hi BHITW,
I noticed that you still have an ongoing case with support.
Upon checking your logs, it seems that sdb (S/N: WD-WCC137HYEHXZ) and sdc (S/N: WD-WCC131TRTU9C) are having issues with binding themselves to md127 which is your data. I would also suggest checking the health of your drives with a diagnostic utility such as WD Dashboard.
Afterwards, you can try opting for a data recovery or clone the disks as suggested with support.
