Wait. I still think the object has to get set with "-c $TYPE". If not the crc error occurs even with the new xfs_db code: # xfs_db -V xfs_db version 4.12.0-rc2 # xfs_db /dev/sda6 xfs_db> daddr current daddr is 0 xfs_db> daddr 2 xfs_db> type agi Metadata CRC error detected at xfs_agi block 0x2/0x1000 Metadata CRC error detected at xfs_agi block 0x2/0x1000 And error is gone when the object is set and the daddr gets set to the correct value. [root@localhost xfsprogs-dev3]# xfs_db /dev/sda6 xfs_db> agi xfs_db> daddr current daddr is 16 xfs_db> daddr 2 xfs_db> daddr 16 xfs_db> type agi > -- > To unsubscribe from this list: send the line "unsubscribe fstests" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
