Please clarify.. > When you say a file system as consistent, It means that you would be able to mount the filesystem. The superblock would be in the consistent state. The point is that even if you loose the data for a couple of files, still your file system will be up and you would be able to access the data for other files. If you loose the consistency of a file system( e.g superblock) then would loose everything. There are other tools that can be used to recover the data of a file or revert back the file to a consistent state but if you loose superblock then you land NOWHERE. > > Thanks > Shyam. > -- Regards, Sandeep.
