Hello,

 

I had to make an unclean shutdown because unraich was unreachable.

I clicked on check parity, and he found like 912 errors, and went to disable the parity drive.

 

So, I went to the store to buy a diskand I launched a data rebuild.

Every disk went green status.

then, I launched a parity check, and he found 912 errors on drive 6, and went disable.

I put a new drive, and start data rebuild.

Every disk went green status.

then, I launched a parity check, and he found 514 errors on parity drive, and went disable.

 

It's a loop.

it happened twice allready, and I've loss data.

 

How to go back to a clean situation?

 

Thanks

Looks like the typical SAS2LP problem, disks that had the issues are probably fine, try disabling vt-d if you don't need it, check for bios update, use the controller in a different slot if available, if issue persists consider getting a different controller, one LSI based.

 try disabling vt-d if you don't need it

 

how do you do that?

I'm sorry, but motherbios bios ? or SAS2LP ? what is VT ?

Motherboard BIOS. VT-d is Intel's name for IOMMU. Google is your friend but you don't really need to know, you just need to disable it. Unless you intend to pass hardware to a VM. How VT-d appears in your BIOS depends on your motherboard, which I don't have the manual for.

Actually, I use VM.. should I buy a LSI based?

 

thanks

You can use VMs without VT-D, but it is needed for PCI pass-through, but yeah, if you can get an LSI based controller, like the M1015 or H310, get one it will probably save you a lot of aggravation.

Many thanks guys !!
