What is happening here - rsync can't copy where cp can, Input/Output errors
I am using rsync version 2.6.9 protocol version 29 on a Fedora 7
system to backup files to a network drive.
rsync is getting I/O errors when copying maildir files (I'm not sure
if the error is happening with other files but these are the only ones
I have found so far).
I have done some tests on one particular directory, "cp -R" succeeds
but "rsync -r" fails:-
home# cp -R .in /freecom/backup/home/chris/Mail/
home# rsync -r .in /freecom/backup/home/chris/Mail/
rsync: rename
"/freecom/backup/home/chris/Mail/.in/audacity/cur/.1172007150.76430_0.newred:2,.PC3iF7"
-> ".in/audacity/cur/1172007150.76430_0.newred:2,": Input/output
error (5)
rsync: rename
"/freecom/backup/home/chris/Mail/.in/audacity/cur/.1172012773.6188_0.newred:2,.P11kJR"
-> ".in/audacity/cur/1172012773.6188_0.newred:2,": Input/output
error (5)
rsync: rename
"/freecom/backup/home/chris/Mail/.in/audacity/cur/.1172032604.34523_0.newred:2,.e0feQB"

rsync: rename

-> ".in/audacity/cur/1172038263.69147_0.newred:2,": Input/output
error (5)
rsync: rename
"/freecom/backup/home/chris/Mail/.in/freecycle/cur/.1172005922.70482_0.newred:2,S.aIqsGA"
-> ".in/freecycle/cur/1172005922.70482_0.newred:2,S": Input/output
error (5)
rsync error: some files could not be transferred (code 23) at main.c(977)
[sender=2.6.9]
If I clear out the destination directory then rsync succeeds once (when
it has to copy the files) but then fails as above every time. If I add
the --inplace option I get:-
home# rsync -r --inplace .in /freecom/backup/home/chris/Mail/
rsync: open
"/freecom/backup/home/chris/Mail/.in/audacity/cur/1172007150.76430_0.newred:2,"
failed: Input/output error (5)
rsync: open
"/freecom/backup/home/chris/Mail/.in/audacity/cur/1172012773.6188_0.newred:2,"
failed: Input/output error (5)
rsync: open
"/freecom/backup/home/chris/Mail/.in/audacity/cur/1172032604.34523_0.newred:2,"
failed: Input/output error (5)
rsync: open
"/freecom/backup/home/chris/Mail/.in/audacity/cur/1172038263.69147_0.newred:2,"
failed: Input/output error (5)
rsync: open
"/freecom/backup/home/chris/Mail/.in/freecycle/cur/1172005922.70482_0.newred:2,S"
failed: Input/output error (5)
rsync error: some files could not be transferred (code 23) at main.c(977)
[sender=2.6.9]
The files in the destination directory seem normal:-
home$ ls -l /freecom/backup/home/chris/Mail/.in/audacity/cur
total 36
-rw------- 1 root root 8192 2007-12-10 20:40 1172007150.76430_0.newred:2,
-rw------- 1 root root 8192 2007-12-10 20:40 1172012773.6188_0.newred:2,
-rw------- 1 root root 12288 2007-12-10 20:40 1172032604.34523_0.newred:2,
-rw------- 1 root root 8192 2007-12-10 20:40 1172038263.69147_0.newred:2,
So why is rsync having problems?

If you run "cp -R" twice starting from an empty destination, does the second run give input/output errors? Matt
