Bug ID: 11866
Summary: rsync fails (failed to re-stat) when using double
fuzzy + link-dest on renamed files
Product: rsync
Version: 3.1.1
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: core
Assignee: [email protected]

When using rsync with --fuzzy --fuzzy (double fuzzy) and --link-dest, rsync
fails if a file was renamed to a new name on the source that does not exist in
the link-dest. As an example:
mj@backup-server:~/foo$ rm -rf .sync && mkdir .sync && rsync -azSHAXxrsyy
--ignore-existing --fake-super --link-dest=/home/mj/foo/current
--files-from=:/home/mj/files-to-backup root@backup-client:/ .sync
rsync: failed to re-stat "/home/mj/foo/.sync/etc/motd.old": No such file or
directory (2)
rsync: failed to re-stat "/home/mj/foo/.sync/var/log/alternatives.log.1": No
such file or directory (2)
rsync: failed to re-stat "/home/mj/foo/.sync/var/log/auth.log.3.gz": No such
file or directory (2)
rsync: failed to re-stat "/home/mj/foo/.sync/var/log/daemon.log.3.gz": No such
file or directory (2)
rsync: failed to re-stat "/home/mj/foo/.sync/var/log/dpkg.log.1": No such file
or directory (2)
rsync: failed to re-stat "/home/mj/foo/.sync/var/log/messages.3.gz": No such
file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code
23) at main.c(1655) [generator=3.1.1]
In each case above, the files which rsync failed to re-stat were ones that
existed in the link-dest (/home/mj/foo/current) but under a different name.
For instance:
mj@backup-server:~/foo$ ls -al /home/mj/foo/current/etc/motd*
-rw-r--r-- 7 mj mj 286 Dec 24 2014 /home/mj/foo/current/etc/motd
root@backup-client:/etc# ls -al motd*
-rw-r--r-- 1 root root 314 Apr 21 06:32 motd
-rw-r--r-- 1 root root 286 Apr 21 06:33 motd.bak
-rw-r--r-- 1 root root 286 Dec 24 2014 motd.old
Note that, in this case, rsync didn't fail on motd.bak, just motd.old. Both
contain the same content, but only motd.old has a matching timestamp.
I can completely reproduce this problem on multiple machine pairs and with
different file sets. The problem is resolved by removing the double-fuzzy
configuration but, of course, that impairs performance.
All rsync binaries involved are version 3.1.1 (debian 3.1.1-3_amd64).
