[Gluster-devel] 1402538 : Assertion failure during rebalance of symbolic links

[Raghavendra Gowdappa]

I need to step back a little to understand the RCA correctly.

If I understand the code correctly, the callstack which resulted in failed setattr is (in rebalance process):

dht_lookup -> dht_lookup_cbk -> dht_lookup_everwhere -> dht_lookup_everywhere_cbk -> dht_lookup_everywhere_done -> dht_linkfile_create -> dht_lookup_linkfile_create_cbk -> dht_linkfile_attr_heal -> setattr

However, this setattr doesn't change the file type.

<dht_linkfile_attr_heal>

        STACK_WIND (copy, dht_linkfile_setattr_cbk, subvol,
                    subvol->fops->setattr, &copy_local->loc,
                    &stbuf, (GF_SET_ATTR_UID | GF_SET_ATTR_GID), xattr);

</dht_linkfile_attr_heal>

As can be seen above, the setattr call only changes UID/GID. So, I am at loss to explain why the file type changed. Has anyone has any other explanation?
