RD5200 raid5 spare drive does not

Hello world

I have no real support of supported Netgear customer (except say update the firmware that they won't help you if you do not have remote access).

I hope that the community will be placed to help me.

My RD5200 is configured with a volume raid5 on 5 discs + a spare (replacement part is online, all the disks are identical)

Failure of one of the raid drives.

-first problem: the hot spare was no need relay.

second problem: the web management console, one there is no way to get the hot spare in raid5. (at least I did not find).

-problem: we received the replacement drive and traded with the defective (same Bay), the record is seen by the system but still once, do not join the raid volume.

Fourth problem: still no way to reach the spare to the Raid volume.

We tried to restart the RD5200. Several times with installed disks. Also stop it, remove the disc, restart and rear Cap. Nothing to get the disks.

We have also updated to 1.4.4 and did the same tests. nothing.

So we have now a Raid5 that is safer and 2 discs which are not usable with the existing Raid5 volume.

Someone at - it a solution? Thank you for your support.

.. .also I'd be very cautious about the interpretation of n-tier RAID (with disc m) when you are really dealing with ZFS (that Netgear could hide particularly well - only 7 instances of the word "ZFS" on a long ReadyDATA OS Manual of 250 pages - the real storage subsystem each ReadyDATA unit is running with...).

In ZFS (or Open-ZFS, see here) RAID 5 or RAID 6 does not exist in ZFS jargon.

Why? because ZFS, a part of the very traditional single vdev and redundant vdev (mirroring of disks n) - the two generally used on the root Pool - its own RAID-Z1, levels RAID-Z2 and Z3-RAID which provide, respectively, for simple parity, double and triple (while you work with single, double and triple parity vdev).

If your installation (the zpool status-v will tell you that) is - in fact - not a RAID5 but a RAID-Z1 vdev created with 5 disks (more the hot spare that has not been activated automatically on the storage pool), then you * just * (just like a RAID5) gradient RAID-Z1 chicken with remaining 4 drives good and 1 bad disc (once again the Hot Spare disk sat down with idle)... so yes He has degraded... something the next time, with a total of 6 drives available on the chassis, to deploy a single parity double RAID-Z2 storage pool (such mass can support 2 simultaneous drive failures, any disk in the pool) which is preferable to a RAID-Z1 with 5 disks plus one slowed Hot Spare.

A good starting point to understand ZFS can be this page but, out there, there are a lot of good documentation on ZFS, levels of RAID-Z and the ways to properly manage a based ZFS storage pool.

  • External CD drive does not recognize the CD burned on El Capitan.

    Using El Capitan 10.11.5 and an external hard drive, I have burned successfully mp3 files iTunes CD - I can play on the computer itself - but an external CD drive does not recognize, even if the Player recognizes the discs once engraved on Snow Leopard and previous models.  What's wrong?

  • Satellite P200 accidents + message: graphic card driver does not work properly

    Hello

    hope that this issue has not been covered before, but I've owned a Satellite P200 for 3 years now, and this week, it crashes all the time.

    When it started going down he gave me a few messages in the sense of "your graphics card/driver does not work properly and windows will be arrested to avoid damage.

    It has progressed to the point where now when I turn it on, I have vertical lines running down the screen and the screen flashes on and outside. Within 20 seconds, it restores the BSOD - 'there was a problem and windows will be arrested. Error Page_Fault_In_Non_Paged_Area"then stops.

    I ran a system restore but the problem remains.

    I have a feeling that my graphics card is toast. Is this good? Are there any other options to try? Thanks in advance for any answers.

    Matt

    Hello

    Sounds like the GPU problem.
    But try the graphics card driver update.
    Use the most recent driver for your graphics card.

    In addition, clean the fans of portable computers.
    Dust and debris could prevent the cooling fans to turn with the best speed and this could lead to a higher temperature which would lead to overheating.
    Use a jet of compressed air. I also use it and it helps to get rid of dust and debris.

    If this is not enough, then a problem of graphics chip would be possible.

  • External Combo CD-RW/DVD-ROM drive does not work with USB 1.1

    Hello world

    I have a problem with the PA3352E - 2 CD 2 CD-RW/DVD COMBO USB 2.0. A colleague is owner of this car and use it on a NB DellC610 with Windows XP on it. The problem is that the drive does not work with this type of nb (with a NB from Fujitsu-Siemens newest there no problems); There is always an error message about "surge." I think it has to do with the USB 1.1 because the player seems to be built for USB2.0. Is it possible to use this drive correctly with usb1.1 (ok, the flow is low, but more important is it works in general)? Unfortunately his nb will not work with USB 2.0...

    Thank you very much in advance.

    Kind regards

  • Satellite 2430: CD/DVD drive does not work - i/o error

    Hello all Toshiba people.i have recently bought a Toshiba Satellite 2430 for a very good price. One thing the carpet * a DVD - ram Uj - 810 drive does not work when I put in any type of cd or dvd, I get this error
    F:\ is not accessible.
    The request could not be performed because of an i/o error.

    I talked to my local computer Wizz and does everything that he suggested to the letter and still the same problem. He suggested updating the bios drivers and the only way to do that is on a disk drive that she cannot take the an or a CD or dvd drive is not working. Can you please help me!

    Begging you a lot
    Michael Borger

    In my view BIOS update will not change.
    I assume that the reader has worked in the past with the same BIOS version
    It is a drive hardware problem or some registry keys are corrupt.

    I think that it s a hardware malfunction may be a matter of lenses.
    But try this;
    Remove the drive from Device Manager and shut the laptop computer. After restarting again the operating system should recognize the drive again. Then you can check the functionality.

    Otherwise, you can remove the disk from the laptop, and then start the laptop without the drive. Then stop the laptop, put the drive in the notebook and start over.
    The firmware should again loads.

    But if these procedures help t, I don t see it differently as for replace the drive

  • DVD/CD-RW drive does not-Tecra A4

    Hi, I have a problem with my Tecra A4.
    My DVD CD - RW drive does not work properly (power is there, but it does not appear on the system), I have temporary installed a drive of DVD - RW from my HP laptop which works very well.
    I tried to run my restore disk (never used), but nothing happens (press and hold C to start). This will only work with the good drive installed or I do something wrong?

    p.s. I bought this second hand, but it's new. He had a damaged screen I have replaced

    Julian

    If the old drive will not read media if it s damage.
    You know that not every disc is compatible with the device because of the csel/slave/master settings.

    You said that the button C doesn't allow you to boot from the disc.
    In this case, I would recommend to get into the BIOS, and there you can change the boot order.
    However, this trick is everything works only if the new drive is compatible and supported

  • Canvio Plus 2.5 "1 TB external HARD drive does not work with USB 3.0

    I've had this drive for about a month.

    I am on Windows 7

    I can only operate by connecting to USB 2.0 ports. It is then visible in 'My Computer'.

    If I connect to USB 3.0, it turns on the case but does not appear in 'My Computer'.

    I tried it on all my USB ports 3.0 - up on one and two in the back of my case.

    I checked my BIOS and USB 3.0 is enabled.

    I tried to follow the suggestions in the user manual, but the drive does not appear in the management of so connected devices on USB 3.0, but it does when connected in USB 2.0.

    Any ideas?

    Hello

    As much as I know the Windows 7 system requires installation of additional USB 3.0 driver.

    Many laptops and computers use USB 3.0 driver that was released by Intel... it is because of Intel chipset...

    I guess that USB 3.0 is already installed, but probably you need to update the driver at least to the newest version...
