Comment 2 Xiaowei Li 2012-06-13 09:49:22 EDT
where can I get the thin_check and thin_dump?
Comment 3 Zdenek Kabelac 2012-06-13 09:51:35 EDT
lvm2 currently does not have dependency on


which must be installed separately

Since not all users are going to use thin - dependency here is tricky - we need to came with some better solution - i.e. check before  lvcreate if tools are avaialble)
Comment 6 Alasdair Kergon 2012-06-13 10:19:07 EDT
We'll have a dependency when this becomes supported, but not while it's tech preview (as we shouldn't install a pure tech preview package for everyone by default).
Comment 7 Xiaowei Li 2012-06-13 10:31:49 EDT
Thanks all for the clarification.

I am putting thin_check_executable = "" to the global{} in lvm.conf to skip this check.
Comment 8 Bill Nottingham 2012-06-13 14:14:52 EDT
Is it expected to be TP still in RHEL 7 GA?
Comment 9 Mike Snitzer 2012-06-13 15:09:08 EDT

> Is it expected to be TP still in RHEL 7 GA?

No, should be fully supported.
Comment 10 Bill Nottingham 2012-06-13 16:41:09 EDT
In that case, I don't see any reason not to add the dep in the RHEL 7 packages.
Comment 12 Peter Rajnoha 2012-10-19 06:22:16 EDT
lvm2 build that requires device-mapper-persistent-data has already been automatically imported from Fedora to RHEL7 as lvm2-2.02.97-1.el7.
