Upgrade State |
"Fully Upgraded" to V7 is FALSE indicating the presence of V6 blocks. This database is ineligible to upgrade to V7. |
"Fully Upgraded" to V7 is TRUE indicating that all blocks in the database are V7 |
Phase 1 starting transitional state. Blocks in this format have the offset applied to 4 byte block pointers |
Phase 1 complete. Directory tree blocks upgraded to 8 byte block pointers |
Phase 2 complete:index blocks upgraded with 8 byte block pointers with an unknown mix of V6 data and local bit map blocks |
Fully Upgraded to V7 indicating that all blocks in the database are V7 |
