ORA-1578 due to misplaced blocks on LINUX. Database Files are stored in NFS filers. A misplaced block means that a block content was written in a different location (different file or different block) overwriting the original block. The corruption is reported in the alert log and by dbverify with message "Bad header found":
The block is healthy (computed block checksum is 0x0) but the content belongs to a different block. In this example rdba: 0x25407478 (rfile#=149, block#=29816) was overwritten with the content of rdba: 0x23c74e36 (rfile#=143 block#=478774)
