Critical, unrecoverable errors

Learn about critical, unrecoverable archive conversion errors, and some possible solutions for correcting them.

Critical errors are not recoverable. Both the cache and the archive are missing or corrupted, so you cannot use any of the data in the database to restore the source. However, it is possible to restore the source from elsewhere.

Error message

CRITICAL: Both cache and archive file for name-version:type:instance are missing or unreadable

Possible solutions

If there is a copy of this source file in a work area or in a database backup, copy the source file to the cache file path. You can use this cache file to restore the archive.

If the source does not exist, then the only way to prevent the error from displaying is to create an empty cache file. Then, either delete the object version from the database or use the ccm archive_fix command to rebuild the archive with an empty source.

See Archive conversion FAQs - fs_check command for instructions on running the ccm archive_fix command.
