Readynas Pro 6 - Err Used disks Check RAIDar

Hi everyone, Yet again for the second time I find myself in unknown waters and issues with my unit. I am running 6.4.2 (have been afraid of uprading) on legacy ReadyNAS Pro 6. I was running 6x1TB ...

ReadyNAS OS 6

ReadyNAS Ultra or Pro or NVX

OK, so did you check RAIDar? What did it say? How many active drives are shown?

Unfortunately, it sounds like you may have lost a second drive, and with it your entire volume. The message is basically telling you it wants to create a new volume, but there is already something on the drives and you need to confirm it is OK to erase them.

I checked with RAIDar now and it does not show any disks.

Said something about dirty disk and that I needed to Format a newly added disk.

Really hope I do not lose my data volume :(

Wohaa I tried removing the one drive I knew was "bad", I had not taken it out before, was still in the slot during this time it had failed.

Tried reboot with slot empty and only 5 drives and now it worked!

Tomorrow it is time for a visit at the local PC store to buy new drives and also a backup wd passport drive :)

  Good. Yes, rarely one bad drive can take down the entire SATA subsystem. When you do replce the bad drive, do so with the power on. That gives you more knowlege of what is going on because the GUI is already booted.

  It's best to use a USB drive that is not powered from the USB port (that is, has it's own power brick).
