Phase 1 – find and verify superblock…
Phase 2 – using internal log
        – zero log…
        – scan filesystem freespace and inode maps…
        – found root inode chunk
Phase 3 – for each AG…
        – scan and clear agi unlinked lists…
        – process known inodes and perform inode discovery…
        – agno = 0
        – agno = 1
        – agno = 2
        – agno = 3
        – agno = 4
        – agno = 5
        – agno = 6
        – agno = 7
        – agno = 8
        – agno = 9
        – agno = 10
        – agno = 11
        – agno = 12
        – agno = 13
        – agno = 14
        – agno = 15
        – process newly discovered inodes…
Phase 4 – check for duplicate blocks…
        – setting up duplicate extent list…
        – clear lost+found (if it exists) …
        – clearing existing „lost+found” inode
        – deleting existing „lost+found” entry
        – check for inodes claiming duplicate blocks…
        – agno = 0
        – agno = 1
        – agno = 2
        – agno = 3
        – agno = 4
        – agno = 5
        – agno = 6
        – agno = 7
        – agno = 8
        – agno = 9
        – agno = 10
        – agno = 11
        – agno = 12
        – agno = 13
        – agno = 14
        – agno = 15
Phase 5 – rebuild AG headers and trees…
        – reset superblock…
Phase 6 – check inode connectivity…
        – resetting contents of realtime bitmap and summary inodes
        – ensuring existence of lost+found directory
        – traversing filesystem starting at / …
        – traversal finished …
        – traversing all unattached subtrees …
        – traversals finished …
        – moving disconnected inodes to lost+found …
Phase 7 – verify and correct link counts…
