Self-heal daemon (if it is in on state) will heal this file from glustertst02 to glustertst01. I'm not sure why you are trying to locate it.

If you want to locate it, this is how you do it :
1) ls -i /bricks/brick1/glu_rhevtst_dr2_data_01/.glusterfs/32/5c/325ccd9f-a7f1-4ad0-bfc8-6d4b73930b9f on glustoretst02.net.dr.dk
2) find the inode number that you will get associated with this file on the same brick (you can use -inum option of find).

You should be able to locate the file. I hope this answers your question.
