Ultra 2 Plus won't boot - support case #18604734
I've been running a ReadyNAS Ultra 2 Plus for about four months now without any problems. A few days ago I upgraded it to the new 4.2.20 firmware, during which I think the system rebooted successfully...
Yep, seems like a run of bad luck lately.
The Ultra 2 is quite dead. With one disk in it, upon pressing Power the fan speeds up, the blue light comes on, the ACT green ligth flickers twice, the fans slow down - and then nothing. RAIDar can't find any units. It does not show up on my net. When you press Power again, it instantly shuts down (no OS lag, so none is alive).
I have tried booting with:
- 0 disks
- first disk with working image (initially) only
- new disk only
Always the same outcome. I have tried cold boots (power cable removed for 30+ minutes). The manual boot override also does not work. I can get to the boot menu and select what I want (I have tried Factory Reset and OS reinstall), but when I push Reset to select it (and go) nothing happens.
I am also concerned with how slow it was when it did run (one Hitachi 7200 rpm 2TB 64MB cache 6Gbps disk). On a test copying 16GB as thousands of small files, it was a a paltry 8-15 MB/s. On a few very large files (Acronis images, 15-23GB each), it reached 51 MB/s. On my QNAT 219P+, with 2 drives in RAID-1, on this same test (run immedialetly afterwards from the same host) I get 46 and 92 MB/s. The QNAP is $80 less ($300 at Newegg) than the Ultra 2 Plus ($380 here at Frys). I wanted to try a different unit (I am a computer engineer who is a senior performance and architecture staff member for a large storage vendor on internal lab testing - I like to play with new things!). And the QNAP has a size limitation problem of 2 x 1.5TB disks (and it is full now with a minimum depth of backups from my home office - my larger sets of enterprise array lab test data are about 16GB compressed, with 1000's of small files mixed with dozens of very big ones, what the Ultra 2 could only manage <15MB/s on). I will likely try a Synology 212+ next.
