           Summary: Copy to nfs mounted partitions fails - RHEL 5.4
           Product: rsync
           Version: 2.6.8
          Platform: x64
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: simon at darkmere.gen.nz
         QAContact: rsync-qa at samba.org


I am running RHEL 5.4 as both client and server. The server is exporting
a partition to client. I am attempting to rsync local files on the client
to the NFS mounted partition. This appears to be failing with the RHEL 5.4
upgrade ( from RHEL 5.3, was working ok then). I strongly suspect this is might
be related to O_EXEL (see http://lwn.net/Articles/251012/ ) as we were getting
similar problems with another application.

$ rsync --version
rsync  version 2.6.8  protocol version 29

The local (source) directory

$ ls -l crontab 
-rw-rw-r-- 1 webmastr webmastr 2681 Nov 16 16:00 crontab


The destination:

$ mount
nfs_server:/wwwroot on /export/www/wwwroot type nfs4
(rw,noatime,bg,retrans=8,addr=172.22.0.12)

$ ls -la /export/www/wwwroot/live/data/test/
total 16
drwxr-xr-x 2 webmastr webmastr 4096 Nov 16 15:58 ./
drwxr-xr-x 6 webmastr webmastr 4096 Nov 16 15:44 ../


Works okay with normal copy.

$ cp -v crontab /export/www/wwwroot/live/data/test/
`crontab' -> `/export/www/wwwroot/live/data/test/crontab'

$ ls -al /export/www/wwwroot/live/data/test/
total 24
drwxr-xr-x 2 webmastr webmastr 4096 Nov 16 16:01 ./
drwxr-xr-x 6 webmastr webmastr 4096 Nov 16 15:59 ../
-rw-rw-r-- 1 webmastr webmastr 2681 Nov 16 16:01 crontab

$ rm /export/www/wwwroot/live/data/test/crontab 

Doesn't when I use rsync.

$ rsync crontab /export/www/wwwroot/live/data/test/
rsync: mkstemp "/export/www/wwwroot/live/data/test/.crontab.Tb0UDW" failed:
Permission denied (13)
rsync error: some files could not be transferred (code 23) at main.c(892)

NOTE the actual data of the file seems to change but is almost always several
years into the past.

Running with more debugging:

$ rsync -vvvvv crontab /export/www/wwwroot/live/data/test/
