Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.
There is minimal size for vdo volume as such (non-native) and if the size is below
minimum vdo exits with “Out of space” error.
It would enhance user experience if lvm would
hint on the minimal native vdo size instead of “command failed” message.
Current behaviour:
# lvcreate --type vdo -L2G -y vg
vdoformat: formatVDO failed on '/dev/vg/vpool0': VDO Status: Out of space
Command /usr/bin/vdoformat failed.
Cannot format VDO pool volume vg/vpool0.
# lvcreate --type vdo -L3G -y vg
vdoformat: formatVDO failed on '/dev/vg/vpool0': VDO Status: Out of space
Command /usr/bin/vdoformat failed.
Cannot format VDO pool volume vg/vpool0.
# lvcreate --type vdo -L4G -y vg
Logical volume "lvol0" created.
Suggestion:
# lvcreate --type vdo -L3G -y vg
Minimal size of vdo volume is 4G.
# lvcreate -v --type vdo -L3G -y vg
vdoformat: formatVDO failed on '/dev/vg/vpool0': VDO Status: Out of space
Command /usr/bin/vdoformat failed.
Cannot format VDO pool volume vg/vpool0.
Minimal size of vdo volume is 4G.

Bruce, would you be willing to take a stab at a patch for this?
Verified with latest rpms, VDO now hints users what the min size should be in bytes.
# lvcreate --type vdo -L4.70g vg
Rounding up size to full physical extent 4.70 GiB
Minimum required size for VDO volume: 5063921664 bytes
vdoformat: formatVDO failed on '/dev/vg/vpool0': VDO Status: Out of space
Command /usr/bin/vdoformat failed.
Cannot format VDO pool volume vg/vpool0.
# lvcreate --type vdo -L4.72g vg
Rounding up size to full physical extent 4.72 GiB
Logical blocks defaulted to 523108 blocks.
The VDO volume can address 2 GB in 1 data slab.
It can grow to address at most 16 TB of physical storage in 8192 slabs.
If a larger maximum size might be needed, use bigger slabs.
Logical volume "lvol0" created.
