Issue

An instance doesn't restart, and it logs the following message on a Linux system :

Note:

Earlier in the logs, there could be a message like the one below:

*ERROR* com.day.crx.core.backup.LowDiskSpaceMonitor Missing file(s). The repository will be closed now.

Another message related to "The data*.tar files are now read-only for security reasons...." could also appear around same time (depending CRX version and patches).

Solution

The messages are thrown when there is inconsistency detected between the index_*.tar and data_*.tar, and your data*.tar files are read-only.

Set back the data_*.tar to read/write. To do this :

- On Linux systems, use chmod command to set file permissions right again.
- On Windows, just remove the 'read-only' attribute on the files.

Then, delete the index_*.tar files, and configure the repository to start in consistency check/fix mode (for both repository and Lucene search index). If no errors are found, remove the consistency check/fix for the next startup to be faster.
