giis-ext4 to undeleted files from another device, mounted to /mnt/d1.
okay,mounting another ext4 device should be fine with giis-ext4.
No, I did not do that.
So that's reason for previous error message on "open_db".
giis-ext4 will be running as a cronjob, scanning
the "protected directories" and keeping a log of changes in there, to be
able to recover them later on?
giis-ext4 will run from cronjob from every "auto update time"
and scanning protected directories and keeps track of files meta-data (inode) but not actual file contents.(data blocks)
If something deleted and assuming the deleted files contents are not overwritten,yet. It recovers them using files meta-data.
So the disadvantage is , giis-ext4 won't recover files deleted before it's installation.
Program received signal SIGSEGV, Segmentation fault.

I haven't seen this error with Fedora/Ubuntu , I'll debug more about this and hopefully find a solution and post it here.
Thanks.

giis-ext4 to undeleted files from another device, mounted to /mnt/d1.
No, I did not do that. I have the the INSTALL file mentioning the "-i"
> 2.Have you added the directory /mnt/d1 using "giis-ext4 --install" option?
switch but I did not know what it meant with "which directories to
protect". I take it that giis-ext4 will be running as a cronjob, scanning
the "protected directories" and keeping a log of changes in there, to be
able to recover them later on?
I've tried that now. However, I cannot add /mnt/d1 (which is a ext4

mountpoint) to the list, as giis-ext4 will segfault then. When I add some
directory from the root filesystem, --install will run successfully.
