File System Check Program
SMM:3-11
SUPER-BLOCK TO SUPPLY NEEDED INFORMATION SEE fsck(8).
The super block has been corrupted. An alternative super block must be selected from among those listed by newfs (8) when the file system was created. For file systems with a blocksize less than K, specifying
−b 32 is a good first choice.
INTERNAL INCONSISTENCY M
Fsck’s has had an internal panic, whose message is specified as M. This should never happen. See a guru.
CAN NOT SEEK BLK B (CONTINUE)
Fsck’s request for moving to a specified block number B in the file system failed. This should never happen. See a guru.
Possible responses to the CONTINUE prompt are:
YES attempt to continue to run the file system check. Often, however the problem will persist. This error condition will not allow a complete check of the file system. A second run of fsck should be made to recheck this file system. If the block was part of the virtual memory buffer cache, fsck will terminate with the message Fatal IO error’’.
NO terminate the program.
