Disk space suddenly lost. Error disk ADA3

[j.vocke]

We are running NAS4Free on a Proliant N36L with 4 pcs Seagte Barracuda 2 TB
ST2000DM001. We had an error on disk ADA3 and now all of our disk space is gone.
Disk is configurerd as SoftRaid. What steps need i to do to get my setup working
again?

it seems that ada3 has died.

its not in the logs

ada0 is reporting some dma read errors in the smart log.

your raid5 arrays MAIN seems to be there in a degraded state. (if one more drive fails all your data will be lost)
however it is not mounted.

so you will need to try and mount it.

and replace the failed disk.

Thank you for your help.
Is it save to try to mount the disk before replacing?

I already ordered a replacement disk and follow the instructions in faq:0058.

you should still be able to access the drives in the degraded state.

however since your first drive is showing problems in the smart report i would be very careful to put much load on the drives

I tried to mount with the ADA3 drive removed, but that did not work.

what was the error message?

did you try mounting it from the console?
