Comment 1 Xiaowei Li 2012-06-13 13:47:10 UTC

lvm2-2.02.95-6.el7.x86_64

Comment 2 Xiaowei Li 2012-06-13 13:49:22 UTC

where can I get the thin_check and thin_dump?

Comment 3 Zdenek Kabelac 2012-06-13 13:51:35 UTC

lvm2 currently does not have dependency on

device-mapper-persistent-data

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 14:19:07 UTC

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 14:31:49 UTC

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 18:14:52 UTC

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

Comment 9 Mike Snitzer 2012-06-13 19:09:08 UTC

(In reply to comment #8)
> Is it expected to be TP still in RHEL 7 GA?

No, should be fully supported.

Comment 10 Bill Nottingham 2012-06-13 20:41:09 UTC

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 10:22:16 UTC

lvm2 build that requires device-mapper-persistent-data has already been automatically imported from Fedora to RHEL7 as lvm2-2.02.97-1.el7.
