I'm always curious about these undeletion attempts and so I've tried it.
But without luck again:
# giis-ext4 -g
Enter your option: 1
giis-ext4: giis-ext4.c:863: open_db: Assertion `error == 0' failed.
Aborted
# echo $?
134
This has been compiled with
- e2fslibs-dev 1.41.10
- libsqlite3-dev 3.6.22
- gcc 4.4.3, with -g -ggdb
I've attached the gdb output and tune2fs output to this email.
HTH,
Christian.
