Hello list,

Recently, we're exercising our container environment which uses lvm to
manage thin LVs, meanwhile we found a very strange error to activate the
thin LV:

“Aborting.  LV mythinpool_tmeta is now incomplete and '--activationmode
partial' was not specified.\n: exit status 5: unknown"

centos 7.6
# lvm version
  LVM version:     2.02.180(2)-RHEL7 (2018-07-20)
  Library version: 1.02.149-RHEL7 (2018-07-20)
  Driver version:  4.35.0

It has appeared several times, but can not be reproduced easily by simple
steps, and it only errors at that moment, after it happens everything seems
OK but only that activation failed.

Looking at the code a bit. At first, I suspect the PV may disappear for
some reason, but the VG sits on only one PV, the setup is simple, the
environment is only for testing purposes, it seems unlikely the PV has
problem at that moment and I don't see any problem message with the disk.

```

dm_tree_node_add_target_area */
2514         for (s = start_area; s < areas; s++) {
2515                 if ((seg_type(seg, s) == AREA_PV &&
2516                      (!seg_pvseg(seg, s) || !seg_pv(seg, s) ||
!seg_dev(seg, s) ||
2517                        !(name = dev_name(seg_dev(seg, s))) || !*name ||
2518                        stat(name, &info) < 0 || !S_ISBLK(info.st_mode))) ||
2519                     (seg_type(seg, s) == AREA_LV && !seg_lv(seg, s))) {
2520                         if (!seg->lv->vg->cmd->partial_activation) {
2521                                 if
(!seg->lv->vg->cmd->degraded_activation ||
2522                                     !lv_is_raid_type(seg->lv)) {
2523                                         log_error("Aborting.  LV
%s is now incomplete "
2524                                                   "and
'--activationmode partial' was not specified.",
2525                                                   display_lvname(seg->lv));
2526                                         return 0;

```
So, does anyone see the same problem? Or any hints to hunt the root cause?
Any suggestion would be welcome!

Regards,
Eric
