I recently upgraded Manticore from 2.7.5-181204-4a31c54 to 5.0.2-220530-348514c86
This fixed many problems we had, but brought one new one. On startup I am receiving:
WARNING: index 'idx_web_log': prealloc: indexes with meta prior to v.14 are no longer supported
(use index_converter tool); /var/lib/manticore/data/idx_web_log.meta is v.13
I understand, index is old and needs to be converted. So I tried:
# index_converter --all
Segmentation fault
I put all index files separately into directory and run it with --path:
# ls -la ~/index/
total 936
drwxr-xr-x 2 root root 101 Oct 8 01:33 .
drwx------ 11 root root 4096 Oct 8 01:33 ..
-rw------- 1 manticore manticore 4 Oct 6 23:57 idx_web_log.kill

-rw------- 1 manticore manticore 942141 Oct 6 23:57 idx_web_log.ram
# index_converter --path ~/index/
Segmentation fault
Still no luck.
Then I decided to copy those index data to old Manticore instance with version 2.7.5. It started well, however it does not show any data now:
Server version: 2.7.5 4a31c54@181204 release
> select * from idx_web_log;
Empty set (0.001 sec)
But when I run strings /var/lib/manticore/data/idx_web_log.ram I see all the data there. Is there any way how to dig it? I assume the index gets corrupted by my index_converter calls and now not old nor new Manticore can read it.
I would like to keep those data, even if they are just logs. Any ideas would be welcome, thanks!
