Hi Did someone find the cause of this problem? I got into the same situation. Setup: Brink1 Brick2 Several clients After shutting doen one of the bricks, we write some data to the shared filesystem After bringing the brick back online self heal fails with the error below. From what I can tell, self heal only fails on symlinks (that didn’t change) in the folder where the changes have been made. Regards Robert Hassing
Emmanuel, For some reason /manu/netbsd/usr/src/lib/libkafs/libkafs.so.9 and its parent dir have trusted.gfid all zero, this is worse. This is brand new for me. Do let me know if you have a test case to get into this situation.
