From 978e85fcd53895cc4902ea0ab3cfcfacc1077315 Mon Sep 17 00:00:00 2001 From: Kotresh HR Date: Fri, 13 Apr 2018 10:52:14 -0400 Subject: geo-rep: Fix syncing of symlink Problem: If symlink is created on master pointing to current directory (e.g symlink -> ".") with non root uid or gid, geo-rep worker crashes with ENOTSUP. Cause: Geo-rep creates the symlink on slave and fixes the uid and gid using chown cmd. os.chown dereferences the symlink which is pointing to ".gfid" which is not supported. Note that geo-rep operates on aux-gfid-mount (e.g. "/mnt/.gfid/"). Solution: The uid or gid change is acutally on symlink file. So use os.lchown, i.e, don't deference.
