Subject: [PATCH 239/260] geo-rep: Fix syncing of symlink
|
|
|
a3470f |
|
|
|
a3470f |
Problem:
|
|
|
a3470f |
If symlink is created on master pointing
|
|
|
a3470f |
to current directory (e.g symlink -> ".") with
|
|
|
a3470f |
non root uid or gid, geo-rep worker crashes
|
|
|
a3470f |
with ENOTSUP.
|
|
|
a3470f |
|
|
|
a3470f |
Cause:
|
|
|
a3470f |
Geo-rep creates the symlink on slave and
|
|
|
a3470f |
fixes the uid and gid using chown cmd.
|
|
|
a3470f |
os.chown dereferences the symlink which is
|
|
|
a3470f |
pointing to ".gfid" which is not supported.
|
|
|
a3470f |
Note that geo-rep operates on aux-gfid-mount
|
|
|
a3470f |
(e.g. "/mnt/.gfid/<gfid-of-symlink-file>").
|
|
|
a3470f |
|
|
|
a3470f |
Solution:
|
|
|
a3470f |
The uid or gid change is acutally on symlink
|
|
|
a3470f |
file. So use os.lchown, i.e, don't deference.
