Information request

Greetings


I managed to delete a file that would require a lot of hours to replace.
(I would be entering all the information again.)

The file is located on a Raid 10 array set up using mdadm - v4.1 - 2018-10-01.
Am running Debian Bullseye (testing).

Looking for suggestions on how to recover the file.

Not sure what other data might be required for anyone assisting so if
more information is required - - please indicate.

TIA

This is really a filesystem question - files are not something that
RAID concerns itself with. So, what filesystem and what type of
file? You might get lucky running photorec (it's not just for
images) on the block device while it's unmounted.

Sorry for the noise folks!

Thanks for the tip Mr Andy - - - - had started that even before I
read your note. Help validate my findings!

Thanking you for your assistance (even if it weren't 100% raid
related - - - grin!).
