My Jenkins yum updates on Fedora 18 have been failing for a while. Finally have a fix that works.
My /var/lib/jenkins directory is an NFS4 mount to a local server.
The first error on yum update was chown permissions. This was fixed by no_root_squash on the server.
To duplicate, from root try to do a chown in /var/lib/jenkins.
(fix no-permission problem)
On the local server:
/etc/exports
/srv *(rw,fsid=0,sync,nohide,crossmnt,insecure,no_subtree_check,no_root_squash)
/srv/jenkins *(rw,sync,nohide,insecure,no_subtree_check,no_root_squash)
The next error on chown/cpio was "invalid argument". There are some older threads about a kernel problem and null characters in uid/gid, another about nfs4 problems etc. The best fix becomes avoiding the problem :)
(fix chown invalid argument problem in yum)
/etc/rpm/macros.jenkins
%_netsharedpath /var/lib/jenkins
At this point rpm will ignore doing chown's and yum is happy.
You might do the second step first to fix the yum problem, but the no_root_squash fix may avoid other problems if that is how you are using your mounted directory.
Some say no_root_squash is a security problem, so either lock down what servers can mount your directory (change * in /etc/exports above), or avoid the problem with netsharedpath.
