A HD in my WD PR4100 32TB server took a crap - need advice
3 Attachment(s)
Hey all, seeking any advice from the many fine minded IT mavens here at the Barn.
I just noticed a red light is on the status indicator of drive number one (of four) slot of my server and was wondering what you would do to best alleviate a data disaster. A quick search showed a similar matching HD may be on back order from Chy-na and not available for a while. The chinks are probably pissed off at the busting of their balloon. Should I just unplug the server and wait until I can install a replacement drive? I can live without it's availability short term. I run it on a $130 or so APC UPS and see no problems reported there, no power issues lately AFAIK. Here are some screen shots related to the issue, what do you think? |
If the spinner drive is bad, you should be able to recover data. It's all done using parity, so you should be able to get the data back without losing any or much at all being that you used RAID 5. Even if you do lose it, you'll still have bits of the data stored across the other drives.

I give zero ****s about trying to repair the bad drive and wish to replace it most rikki-tik. |

Depending on the RAID setup/rules, the drive is already mirrored on one of the other three. I know there's a process to go through to replace one, but if you had it set up that way, you shouldn't need to do any physical recovery.

If I recall correctly from my working years, any 3 of your RAID5 drives have all the info needed to rebuild a failed 4th drive. If your hardware is hot swappable, you just unplug the bad drive & plug in the replacement. If not, power it down, replace the drive, & turn it all back on. You might be prompted to recover the data onto the new drive. It takes a while, but the new drive will be rebuilt as a participating member of the array.
From your pics, it looks like a WD drive system. Might be good to look at their documentation for drive replacement procedures. |
Should only have to match the specs for a replacement drive. 8TB, 5400 RPM, 6 Gb/s, 256MB cache according to a quick search of wd80efax-68knbn0

I have the same PR4100 and mine is loaded with WD80EFAX-68LHPN0 drives.

Well, I ordered a replacement HD from Amazon and it should be here in a week to ten days. I believe/hope it will be hot swappable, I'll know more in a couple of days when I read up on the replacement process. Thanks for the advice guys!

Not only can you replace the drive and rebuild your RAID, you can even upgrade your storage space. Throw an 8TB WD Red in place of the bad one, wait for the RAID to rebuild itself, and then repeat the process for the other 3 drives.
Easy Peasey! |

I'm always needing more storage. I wish it was as simple as replacing hard drives with bigger ones in the arrays, but not all drives are supported, and then there are drive size limitations. If there wasn't, that R6 would be 132TB instead of 24. |

So I put it into hibernate, and it’s still in the process of doing its thing with a msg something like drive is currently shutting down displaying on the device itself. I assume once it’s entered hibernation I can simply unplug it from the power, but not 100% sure. Looks like I may have to call tech support, I know this hibernate mode appears to really irritate people. |

Is that all static storage, like dvd's and such? Or, are you doing something capturing dynamic data that requires such extensive size? |

I was just contemplating running Plex directly on the PR4100 last night. It has hardware transcoding, an intel processor and supposedly was designed for Plex. But there are so many complaints about how poorly it performs that I think I'll just keep it on one of the minis. |
