Abstract
A method and system for conducting an integrity check of system and user metadata when the metadata is mounted. A filesystem reviewer (48, 74, 84) is embedded within software of a server node. A mutual exclusion lock is obtained on the selected metadata (54, 82, 116, 202, 242, 302). An automated verification of the locked metadata is conducted (58, 86, 120, 156, 206, 246, 306) while the filesystem is mounted. In addition, an automated salvage of the locked metadata may be conducted (62, 90, 124, 158, 210, 250, 310) while the filesystem is mounted. The verification and/or salvage of the locked metadata can be applied to system, user, and/or a portion of the user metadata.
