It may be related to NFS matter. The possible related NFS mount options are - nfsvers=3 or 4 - dirsync On my test system, all these combinations have no problem. - 4 without dirsync --> slow but works - 4 with dirsync --> works - 3 without dirsync --> works - 3 with dirsync --> works Would you try them?
