[Gluster-devel] upstream: Symbolic link not getting healed

[Venkatesh Somyajulu]

Hi,

For the upstream master branch, I found that symbolic link is not getting 
healed.

How I reproduced:
-----------------
1. Created replicate volume with 2 bricks in a replica.
2. Created file from the mount point.
3. Killed one of the brick of replica.
4. Created symbolic link to that file from mount point and then brought the 
killed brick back up.

Tried to heal by both a) Mount Process and b) Self heal Daemon

a) When self heal daemon is off:
6. Gave ls at mount point.
   Observation: Rather than file getting healed, getting this output. 
               ls: cannot read symbolic link Link: No such file or directory
                File  Link

b) When self heal daemon is on:
6. "gluster volume heal volumename full" fails to heal and the output includes:
   [2013-12-17 10:21:49.863960] I 
[afr-self-heal-entry.c:1502:afr_sh_entry_impunge_readlink_sink_cbk] 
0-volume1-replicate-0: readlink of /Link on volume1-client-1 failed (Stale file 
handle)


Still root causing the issue. Seems link ESTALE error needs to be handled 
properly.

Venkatesh
