Subject: Permissionproblem on CIFS share.
To: cygwin@cygwin.com
Content-Type: text/plain; charset=UTF-8

Hi,

I have a permissionproblem on a CIFS share.

The line in fstab reads "//fileserver.company.de/git    /mnt/git
 cifs    binary,posix=0,user,noacl"

I then try to push some Git changes, but it does only work by
repeating the push multiple times.
Following you see the execution history, I did not change anything in
between, I just retried the push until it was finally through and all
changes are there in the end. My workaround is to do "watch -n 1 'git
push 2>&1'" and waiting for it to finish successfully, but this only
works for small repos. For bigger repos this needs ages.

Has anyone any idea what is the cause and how to resolve it?
As a sidenote, the same worked fine when the CIFS share was from a
NetApp Linux server.
But then it died and now it is a CIFS share on a Windows server.
Before it worked fine, now I see this strange behaviour.

I hope someone has a good idea.
And here the execution transcript:
