Enabling bit-rot
For reasons buried in the long forgotten past we have NAS units without bit-rot protection on almost every share/file. Most systems are using Raid1enabled.
If I understand this circumstance properly, once bit-rot is enabled I need to actually copy and read back the associated files to get the protection enabled. Is my understanding correct or is there some way to force a checksum event for the newly enabled bit-rot files/shares?
Would doing a scrub function do the same thing – establish checksums for existing files?
The short answer to my original question is that for bit-rot protection to be enabled it must be set on the file/share and then all data after that point that is moved/used/copied will have the associated protection. Stuff that just sits there is not protected.
I set up a temp share and copied major parts of my data to the temp share. Subsequently I copied back to the same location that had bit-rot protection enabled. Took some time but certainly not impossible.
