Comment 4 Amar Tumballi 2012-05-31 17:22:20 UTC

Now, when one creates the files/dirs, gfid backend corresponding to the actual file is created.

[root@supernova s1]# for file in $(find .) ; do echo -n $file " -- "; stat -c %i $file ; done
.  -- 531583
./rand  -- 531837
./rand1  -- 531841
./testfile  -- 530599
./.glusterfs/66/e4/66e4a420-9960-4a32-852f-cf6db0bcadef  -- 530599
./.glusterfs/d3/a2/d3a25e4f-9a03-4b7c-8365-d257ca8b3455  -- 531841
./.glusterfs/0b/50/0b500389-df9d-499d-ab27-9dcd0464cd18  -- 531837
./.glusterfs/00/00/00000000-0000-0000-0000-000000000001  -- 538507


Notice the same inode number for the files. (rand1 and 25e4f-9a03-4b7c-8365-d257ca8b3455)
