Could we recover Mongo records from the data files only without namespace files? I am missing a namespace file from the Mongo db path. I only have data files with number extensions (e.g. report.4,report.5). Is there any way to recover the mongodb dump from the data files?
Hmm.. You have MMAPv1 engine in use... If your mongodb version is BEFORE 3.0, you can use mongodump and --dbpath parameter to read data directly from data files.
