SYNOPSIS

AVAILABILITY

DESCRIPTION

The fsdb command is a powerful tool that can modify the structural elements of a file system. When used correctly, it can repair damaged file systems. However, when used incorrectly, it can cause serious and possibly unrepairable damage to a file system. VERITAS therefore recommends that fsdb be used only in close consultation with VERITAS technical support.

Cluster File System Issues

Although there are no specific cluster file system issues with this command, fsdb is meant for knowledgeable VxFS file system users and should be used very carefully to avoid losing data.

WARNINGS

Always run a file system check after using fsdb to modify a file system (use "fsck -o full, nolog" ).

Some aspects of fsdb apply to a specific VxFS disk layout version. Only the VxFS Version 4 and Version 6 disk layouts are supported.
