Several file systems were replicated. After customer verification, the replicated file systems were put into production. An hour later, the datamover panicked causing a reboot. After the reboot, users started complaining of missing files on one file system.
The customer thought it was an unsuccessful replication. We found the reported missing files in the lost+found directory.

What could have caused the move?

A.
System performed fsck on the file system while it was coming up; moved the uncoverable inodes to the lost+found directory

B.
Buffer overflow occurred during panic

C.
System flushes all files during panic to lost+found dir

D.
Replication playback was incomplete before replication got aborted
