The client is windows 8 enterprise with all the updates, the servers are
rhel 6.4, gpfs, sernet samba 4.1.4-7, sernet ctdb . I
also have a windows 7 enterprise client I should test. Also, whats the
difference between the sernet ctdb 1.0.1114.7-1 and what seems to be the
"latest" ctdb v2.5.1 on ftp.samba.org other than a timestamp difference of
a few months? Why is the sernet ctdb using the v1.0 line and not the v2.5.1
line ? I think I mentioned this earlier but the binary provided ctdb 2.5.1
rpm's from samba.org or a self compiled (rpmbuild -bb) version refuses to
be installed with the sernet-samba 4.1.4-7 packages due to a requirement
that it can only use ctdb 1.0.115 (a typo in the .spec deps I guess?). The
only way I can install 2.5.1 is with make install, but again I have doubts
about whether I should use it with sernet-samba which seems to not like
anything other than ctdb 1.0.x .
