Solaris Tips : How to resolve BAD SUPERBLOCK

Superblock in UNIX operating system consists of important information about the file system and behavior tuning parameters. Corruption in superblock mainly occurs due to file system corruption, unexpected system, virus infections, and more. Two major hazards of superblock corruption are unmountable hard drive and data inaccessibility.

Resolution:To troubleshoot and resolve the above error message and access the hard drive data, you will need to take below actions:Firstly, you need to run the FSCK command manually and try to boot the system.If the problem persists, then you will need to use alternate superblock.However, if both the above actions fail to resolve your issue and the data still remains inaccessible, then you will need to reinstall Sun Solaris operating system.
