fsck<\/strong> is the command used in UNIX for checking filesystem for any inconsistencies, usually caused by abnormal shutdown. These abnormal shutdown may be caused by some hardware failure or power failure.<\/p>\n

fsck also\u00a0has options to repair filesystem as well.<\/p>\n

Syntax:<\/strong><\/p>\n

fsck<\/font><\/strong>\u00a0 [ -F<\/strong> fstype<\/em>]\u00a0 [-V<\/strong>]\u00a0\u00a0\u00a0 [-y<\/strong>Y]\u00a0\u00a0\u00a0 [-o<\/strong> options<\/em>]\u00a0 special<\/em><\/font><\/p>\n

-F<\/font><\/strong> fstype<\/em>\u00a0\u00a0\u00a0\u00a0 type of file system to be repaired ( ufs , vxfs etc)<\/font><\/p>\n

-V<\/font><\/strong> verify the command line syntax but do not run the command\u00a0<\/font><\/p>\n

-y<\/font><\/strong> or -Y\u00a0 Run the command in non interactive mode – repair all errors encountered without waiting for user response.<\/font><\/p>\n

-o<\/font><\/strong> options\u00a0 <\/em>Three options can be\u00a0 specified with -o flag<\/font><\/p>\n

b=<\/font><\/strong>n<\/strong>\u00a0\u00a0<\/em> where n is the number of next super block\u00a0 if primary super block is corrupted in a file system .<\/font><\/p>\n

p<\/font><\/strong> option used to make safe repair options during the\u00a0 booting process.<\/font><\/p>\n

f\u00a0<\/font><\/strong>\u00a0\u00a0 force the file system check regardless of its clean flag.<\/font><\/p><\/blockquote>\n

Most\u00a0 *NIX machines has fsck, but special attention should be made when dealing with Sparc hardware or Solaris UNIX in general.<\/p>\n

When doing fsck, make sure that you are checking the ‘raw’ device and not just the logical disk.<\/p>\n

Check this out <\/a>to determine the raw device of a solaris server. We’ll post more of the topic soon.<\/p>\n","protected":false},"excerpt":{"rendered":"
