[linux-lvm] LVM 2.0/Device-Mapper 1.0 update

[Alasdair G Kergon]

I've updated the LVM 2.0 and Device-Mapper 1.0 tarballs
at ftp.sistina.com to incorporate a few minor bug fixes.


ftp://ftp.sistina.com/pub/LVM2/tools/LVM2.0-stable.tgz
  (CVS tag v2.00.06)

ftp://ftp.sistina.com/pub/LVM2/device-mapper/device-mapper-stable.tgz
  (CVS tag v1.00.03)


Details in CVS; or see lvm-commit mailing list archives.

Do these work on the 2.6.x test series yet?

2.6 has device-mapper in it already, but it doesn't have snapshots or
the mirror target yet (needed for pvmove).

Just to let you know: My pvmove problems are not affected by this new
version. Same symptoms as before.

Well, many thanks for producing all the diagnostics: 
I don't know what's wrong yet, but I have managed to
reproduce your setup on a test machine here and 
I reproduced the problem 5 minutes ago.

I attach a patch which should workaround the problem.

Memory that is still referenced gets freed if pvmove
tries to move more than 8 LV segments at once, so all
pvmove (dm_mirror target) users should apply this patch.

It's in CVS now, and I'll update the tarball on the ftp site
to 1.00.04.

  does this translate to my issues with LVM under test2 and later to
  be known issues?  on -test4 I now get a message from vgscan telling
  me that lvm-mod isn't loaded.

I'm typing this on a machine running 2.6.0-test4 and LVM2.  I've had
no problems so far.
