GDU not ignoring directory about gdu HOT 6 CLOSED

That is strange. gdu /mnt/backups/minio -i /mnt/backups/minio/dirC should work properly, just tested similar case locally.

Do you have something not ordinary? Maybe case insensitive file system?

from gdu.

It's a standard Ubuntu 20.04 install. The partition is ext4. The directories inside /mnt/backups/minio/ are actually minio buckets. dirC is actually the bucket used for storing backup data from urbackup but I can't see anything that would make this directory anymore special than the other directories at that same level.

I can try to provide any other info if you can tell me what you need.

Do you have some symlinked directories on the path? Maybe gdu is getting different absolute path.

from gdu.

Yes /mnt/backups/minio/urbackup (or /mnt/backups/minio/dirC as per my example) has lots of symlinks inside of it. Even du and ncdu take absolute ages to process this directory. That's the reason I was trying to exclude it.

Does --ignore-dirs in gdu do pre or post filtering? It sound like it is probably doing post filtering and that's why I am still seeing it processing that directory and if I wait long enough for it to finish, then it will exclude that directory from the final display (I guess I could test it).

If that's the case, it's looking like my only option is going to be to go through each top-level directory separately to then be able to ignore dirC.

from gdu.

Gdu does pre filtering. It checks absolute path of the every directory when entering it and checks if it matches some of the ignored dirs paths (exact match). If it matches, it ignores the directory completely.

My guess is that gdu sees different absolute path than /mnt/backups/minio/dirC.

I could probably add some debug flag to log all directory paths which are processed.

Hello,

I just encountered the same issue. Indeed, the reason why gdu was still looking at the directory to ignore was that the directory to ignore was reachable through a symbolic link in my home directory. I fixed it by ignoring the path through the symbolic link as well.

To be more specific, what I did was: instead of gdu --ignore-dirs /absolute/path, I did gdu --ignore-dirs /absolute/path,/absolute/path/through/symbolic/link.

The way that du indicates to ignore directories is through relative paths. Perhaps this would make it easier to avoid situations like mine or @mahomedh 's. @dundee perhaps this is worth looking into?

Thanks.
