Fried(?) ReadyNAS NV+ #19179228

1) See http://www.readynas.com/kb/faq/hardware/how_do_i_replace_the_stock_power_supply_on_the_readynas_nv. That will tell you how to remove the PSU. When did you purchase your NV+ and what region (e.g. US) are you in? Is your serial number in this range?: http://www.readynas.com/forum/viewtopic.php?f=1&t=10259 (depending what region you are in you may be able to get a replacement PSU if your serial number is in that range)
2) Hopefully they'll be fine. Usually they probably would be in a case like this. If not, I hope you have a good backup.
3) With another v1 yes. I would suggest using a spare disk (must not be from your array) to ensure the firmware in the replacement chassis isn't older than the firmware on your disks.
4) No. The RAID format of the v2 is different.

Thank you. This was purchased in August 2007 in the U.S. and the serial number does fall within that range. I assume I
should contact Netgear support to ascertain on what terms I can obtain a replacement power supply.

Very much appreciated.

Hey. . .don't know where you are physically located, but I just updated from my old NV+ units to Pro. If you still just want the units (with no hard drives), let me know! I've got two.

One of them looks pristine (still in the original box). The other looks awful, but is still working great (humidity here in Hawaii takes its toll on external enclosures).

I might well be interested. I've contacted Netgear support to see what my options are. Please feel free to contact me directly at sims@bu.edu (located in Boston).

Thanks.

Netgear support was nearly impossible to reach this week (possibly due in part to flooding the the Phillipines) but when I did reach them via (and after a long wait on) the "Prosafe Hotline" (1-855-PROSAFE in the U.S.) they agreed to send a replacement power supply without further ado. MDGM: Should I, to be on the safe side, remove the existing array and install a bare drive before restarting after the power supply change? I would have thought it unnecessary, unless the firmware state is vulnerable to having been altered by the power supply failure.

Thanks for any insight you might have to offer. And thanks more generally for the help.

I think you should be O.K. But it does depend if the failed power supply did any damage. Usually the failed power supply can simply be replaced following the instructions in the FAQ that I linked to above.

Do be careful when handling the disks and if you do remove them be sure to label the order so you can put them back in the right order (be sure to power down the NAS, remove the spare disk - not from your array - and put all the disks from your array back in before powering the NAS on).

Thanks very much. Sounds like a plan.

I received a replacement P/S which installed without problem. I booted the device with a single bare drive, which proceeded without incident, except that while Raidar identified the device on the first boot, it took a second time around before I could access it via frontview. After powering it down (authorizing a volume scan on restart) and reinstalling the preexisting array (3x500, in the proper order), the following occurred.

(1) It booted, started a volume scan, which took quite some time, and then proceeded with a quota check (which had not explicitly been authorized), and which seemed to hang at 0.1% for hours, so I tried forcing a shutdown with the power button. The device seemed not responsive, so I left it, and when I came back later the quota check seemed suspended and I could power it down. During this episode the device was visible on Raidar.

(2) On reboot, after some time during part of which it reported Resynching volume 2, the device then reported "Found bad volume." It did respond to an attempt to shut it down.

(3) On third restart it first reported that it was Resyncing Volume 2, after which it again proceeded with a quota check, which after 18 hours has gotten to 4.3 percent, at which pace it will take three weeks or so to complete. During this time the device has been visible on Raidar, and has consistently displayed the same information, even on repeated rescans. It reports that it is engaged in a quota check but no progress information is visible. Drive 1 (a Seagate ST3500320AS) reports temperature, nominal capacity and "6 ATA Errors"; drive 2 (ST3500630NS) reports nominal capacity and temperature; drive 3 (630NS) reports capacity, temperature, and "1 ATA Error". (Prior to the P/S failure, Smart data on the 630NS's had reported no errors; the 320AS had reported a small but stable number of ATA errors, possibly the 6 it is currently reporting, and a slowly growing number of "LPStat events," the significance of which I had never been able to figure out.) The array LED reports usage and capacity, but not at any time progress of resynching or quota check. All lit LED's are green, except for the blue LED at the left side of the Raidar display.

Does anyone have any advice to offer? Do I just walk away and check back with it in a week or two?

Contact support for advice and post your case number

My first attempt at that took four tries via three mediums over five days and 40 minutes in a telephone holding queue. Do you have any suggestions about how to go about doing that in a manner that is more expeditious and reasonably calculated to put one in touch with someone in a position to be of help? My first two efforts, via email, fetched delayed acknowledgements and ultimately nothing more.
