RAID 6 Recovery from QNAP - TS809U

[jag17]

I have QNAP TS809U with 8 x 1TB Hard disks running on RAID 6

All disks are good and I managed the image them all.

Has anyone got the parameters for this QNAP model?

BLOCKSIZE:
PARITY:
ROTATION:
DELAY:
FIRSTDELAY:
OFFSET:

Thank you

Hi,

I don't have that information for that specific RAID, but you can start by finding what's the FS, and based on that you have offset.
Also, almost all of those I had where 64kb stripe size.

To be honest, for QNAP I think supports LVM so just use info from LVM to get config.

Thank you. Sorry I am new to RAID recovery. Can please provide bit more details about getting info from LVM?

From the spec the FS seems to be ext3. So if it ext3 what would be the offset?

If you're new to RAID, try to understand first how RAID works and then try to rebuild it, because no one can tell you directly what's the config of your RAID without looking at it.

If data is valuable, you should contact a pro to assist you.
