Recover QNAP data LVM MDADM EXT4 Volume files.
Posted: Sun May 23, 2021 4:00 pm
Hi all, perhaps this question was already posted in the past, but could not find anything using the search option. If so, I apologize.
I have a QNAP where I have deleted the a folder by mistake, and used the option to permanently delete the files.
After I made the mistake, I tried running the linux version on my Qnap and used the Mac/PC version to connect to the Qnap by network and scan the disks.
I found the following:
i see a disk using /share/CachedevX ( also see it as DiskX )
I see the same disk with 5 partitions, one using an LVM volume with the correct name.
I see the same disk sys-mdadm-X
I already scanned the LVM volume for about 80% ( I cannot due a complete scan, because program hangs ).
After the scan, I do the "show files". I wait until the scan is finished, which only takes about 3 hours. it stopes at 1.7 TB mark, but the disk itself is 8 TB. the folder I'm searching for is not visible in the list. when using the hex editor further down on the hdd, I can see some of the files and folders saved there.
is there some network limitation or is there something going on with LVM volumes, that I cannot see the deleted folders?
is there a way to have the indexed data but also only the region of the hdd, the data is saved on?
If I only scan the region of the HDD where the data is saved, I can only recover RAW files, which I preferably do not want.
Does anyone have a suggestion what I could do?
Thank you in advance!
