Possible actions after incident commander approval:
|
|
1. Truncate a verified active log file:
|
|
$0 --truncate-file /path/to/large.log --execute
|
|
|
|
2. Restart a specific service holding deleted files open:
|
|
$0 --restart-service service-name --execute
|
|
|
|
Review application impact before either action. Truncation preserves the file inode but destroys file contents.
