  Filter out partitioned device-mapper devices as unsuitable for use as PVs.
  Also notify lvmetad about filtered device if using pvscan --cache DevicePath.
  Use LVM's own selection instead of awk expressions in clvmd startup scripts.
  Do not filter out snapshot origin LVs as unusable devices for an LVM stack.
  Fix incorrect rimage names when converting from mirror to raid1 LV (2.02.112).
  Introduce pvremove_many to avoid excessive metadata re-reading and messages.
  Check for cmirror availability during cluster mirror creation and activation.

I am having trouble with tests. One first test reports:

-- Timed out normal:shell/lvconvert-raid.sh (end) ---
Running normal:shell/lvconvert-repair-dmeventd.sh

Then all tests time out (and it looks like that even the host "lvm", tried in another wondow, does not work anymore). Hter is an overall time out of 5 h or so for the tests, so that eventually, the tests end. But the system is left into a weird state (when shutting down, the system cannot umount /, "system is busy",but nothing is reported by "mount").

Problem is: at least 3 packages are involved: kernel, udev, and lvm itself. What to check first, I do not know...

[Pierre Labastie]

I forgot to says that I have kernel 3.18.2.

Downgrading to LVM2-2.02.114 still gives the same behavior.

But bingo! Downgrading kernel to 3.17.4 allows the tests to run to completion. Trying again with 2.02.115 and kernel 3.17.4.

[Pierre Labastie]

Version 2.02.115 + kernel 3.17.4: allows also the tests to run to completion. There are 2 failures, 7 warnings, and 37 tests skipped (out of a total of ~200). Also, all 200 "cluster" type tests are skipped, but I guess the reason is just that my VM does not have suitable (emulated) hardware or configuration.

I guess I've gotten to try with latest kernel (3.18.3).

[Pierre Labastie]

3.18.3 gives times-out too. Problem is that it is not reproducible: the first timed out test is not always the same!

[Pierre Labastie]

Do not know what to do with the book. Should I update (seems that for day to day use, LVM is OK), with a note about the kernel version?

[Pierre Labastie]

Looks like kernel 3.18.1 is OK

[bdubbs@…]

Intermittent problems are almost always HW related. A short comment about timing issues would be appropriate, but go ahead and update please.

[Pierre Labastie]

Well: the tests pass always (well a couple of times for each) with kernel 3.17.4 and 3.18.1. Anyway, will update (tomorrow, it is getting late here).

fixed at r15383 and r15384
