Just to update in case any one else has this issue… The chkdsk took over 3 days to run:
It left 1.2TB of files (approximately 10% loss) in the found.000 folder in the root of the drive. The files were still in folders…
As the filenames within folders are still correct I am manually restoring the folders to the blobs directory. I copy the name of a file…
Search the storagenode.log for the original PUT request…
Find the satellite ID, crossmatch it with the blobs folder (link), rename the dirxxxx.chk folder to the first two letters of the Piece ID (z6 in this case) then move the folder back to the correct location…
400 folders to go and then I’ll start the node again to see if it survives
