Fixed In Version: ceph-nvmeof-container-1.3.4-1
Doc Type: Known Issue
Doc Text:
.Some namespaces are not visible after multiple gateway scale-downs Previously, in cases where multiple gateways underwent a scale-down procedure, if a lb group change occurred in the removed gateway, the namespace might not be visible to the initiators. As a result, the ana grp id of that namespace would be reported incorrectly by some of the gateways. With this fix, after a scale-down operation, stop and then restart the daemons that are showing the incorrect ana grp id.

Description of problem:

If the number of gws is scaled down (e.g. a gw that was a part of the gw group is removed), and then if changing the lb group of the last namespace in the ana group that owned by the removed gw, the ana grp id of that namespace will be reported incorrectly by some of the gws.
