# To check if btrfs check can handle half dropped inodes.
|
||
|
|
# Such inodes are orphan inodes going through file items evicting.
|
||
|
|
# During that evicting, btrfs won't bother updating the nbytes of the orphan
|
||
|
|
# inode as they will soon be removed completely.
|
||
|
|
#
|
||
|
|
# Btrfs check should be able to recognize such inodes without giving false
|
||
|
|
# alerts
|
||
|
|
#
|
||
|
|
# The way to reproduce the image:
|
||
|
|
# - Create a lot of regular file extents for one inode
|
||
|
|
# Using direct IO with small block size is the easiy method
|
||
|
|
# - Modify kernel to commit transaction more aggresively
|
||
|
|
# Two locations are needed:
|
||
|
|
# * btrfs_unlink():
|
||
|
|
# To make the ORPHAN item reach disk asap
|
||
|
|
# * btrfs_evict_inode():
|
||
|
|
# Make the btrfs_end_transaction() call after btrfs_trncate_inode_items()
|
||
|
|
# to commit transaction, so we can catch every file item deletion
|
||
|
|
# - Setup dm-log-writes
|
||
|
|
# To catch every transaction commit
|
||
|
|
# - Delete the inode
|
||
|
|
# - Sync the fs
|
||
|
|
# - Replay the log
