Comment 1 for bug 2035572

Some steps to reproduce this bug by causing a "NotFound" error.. (although the error doesn't appear to be the same in the log in the description) :

Set manila's debug logging

$ manila create nfs 1 --name testshare
$ manila access-allow testshare ip 10.10.10.10

check manila logs for the export ID of the rule that was just created; for example if it is 1001; run:

 sudo dbus-send --print-reply \
    --system --dest=org.ganesha.nfsd /org/ganesha/nfsd/ExportMgr \
    org.ganesha.nfsd.exportmgr.RemoveExport uint16:1001

on the node where ganesha is running; then try to delete the share:

$ manila delete testshare

list the shares, the share must be "error_deleting"

+--------------------------------------+-----------+------+-------------+----------------+-----------+-----------------+---------------------------------------+-------------------+
| ID | Name | Size | Share Proto | Status | Is Public | Share Type Name | Host | Availability Zone |
+--------------------------------------+-----------+------+-------------+----------------+-----------+-----------------+---------------------------------------+-------------------+

manila-share log shows the following:
