Destroyed Raid at disk replacement
Dear Helpers :) Morning did not start good for me. Sleepy, and less of conscious I have started replacing disk. I have took off first drive from raid, put new one, and instead of destroy and fo...
Can you give us some more details on what you were running before (how many disks, what RAID mode)?
Also, do you have a backup of the data?
raid mode was flex-raid,
3x3TB+1x4TB - new one
i have started last drive replacing from 3TB>4TB few days ago and finished today morning, then started replacing first first drive,
no config backups or data,
so theorethicaly I have got old 1st disk out of NAS still keeping old configuration and part data,
1st new disk still in raid (not touched yet)
3xold raid drives in raid with data with destroyed volume/raid
what confused me to click the wrong set?
first time - main raid was at first place and spare on bottom
second time - spare drive was displayed as first and rest of raid in the bottom
regards,
Carlos
I don't know of any way to undo the mistake.
One option is to contact paid Netgear support, and get a data recovery contract. https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
You could also try RAID recovery software (getting a package that supports BTRFS). ReclaiMe is one that several folks here have used with success. You'd need a way to connect the disks to a PC - either SATA or through USB adapter/docks (possibly a USB enclosure).
Well, I still have disk 1 and 4 before i have started upgrading them, would it help?
