RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 1 Corey Marthaler 2016-09-15 17:48:08 UTC 
Same thing on ext4 and xfs (comment #0 was xfs, this is ext4).

Comment 3 Bryn M. Reeves 2016-09-16 09:09:05 UTC 
I've not managed to reproduce this yet; I'll test again today with the RHEL7 builds.

If you have the test setup to hand still it'd be useful to see the group tags stored with the regions:

# dmsetup message $DM_DEVICE 0 "@stats_list"
Comment 4 Bryn M. Reeves 2016-09-16 09:55:14 UTC 
I can reproduce this now, using exactly the file names and sizes from comment #0:

Somewhat bizarrely, it does not reproduce with my standard set of test image files:

# ls /var/lib/libvirt/images/

vm.img            1606 1606-1607 group     6.55g   1.00g      1   1.00g dmstats

I think it's a bug affecting only groups where the first group member (leader) is also the last region present on a device:

# dmsetup message vg_hex-lv_root 0 "@stats_list" 
0: 23396720+776 776 dmstats DMS_GROUP=fsxmsjjuuybvvuvffucprynnaujtadghxgv:0#-
1: 22092536+184 184 dmstats DMS_GROUP=joxcobxp:1#-
2: 23631960+880 880 dmstats DMS_GROUP=nnkgyhnkfnlfrhhbucmybomlhokgkotaeghenu:2#-

Region 2 is the only member of group 2.

If I add a 2nd region (even without adding it to group_id 2's DMS_GROUP tag), the missing group appears:

# dmstats list --group vg_hex/lv_root
Name                                   GrpID RgID ObjType RgStart RgSize  #Areas ArSize  ProgID 
fsxmsjjuuybvvuvffucprynnaujtadghxgv        0    0 group    11.16g 388.00k      1 388.00k dmstats
joxcobxp                                   1    1 group    10.53g  92.00k      1  92.00k dmstats
nnkgyhnkfnlfrhhbucmybomlhokgkotaeghenu     2    2 group    11.27g 440.00k      1 440.00k dmstats

Seems to be a bug in the end conditions for the group walk iterator.
Comment 5 Bryn M. Reeves 2016-09-16 11:59:32 UTC 
Definitely a bug in the group walk - the groups are correctly recognised and populated, and the walk is correctly set up - it just doesn't visit the final group in the case that that group has one member, and that member is the final region on the device:

Comment 6 Bryn M. Reeves 2016-09-16 12:11:05 UTC 
The test for the end of group table in _stats_walk_end() is wrong:

1526 static int _stats_walk_end(const struct dm_stats *dms, uint64_t *flags,
1527                            uint64_t *cur_r, uint64_t *cur_a, uint64_t *cur_g)
1528 {
[...]
1544 
1545         if (*flags & DM_STATS_WALK_GROUP) {
1546                 if (*cur_g < dms->max_region)
                                ^
1547                         goto out;
1548                 *flags &= ~DM_STATS_WALK_GROUP;
1549         }
1550 out:
1551         return !(*flags & ~DM_STATS_WALK_SKIP_SINGLE_AREA);
1552 }

The comparison with dms->max_region should be '<='

Making this change fixes the --groups output:
