Subject: [PATCH] nvmf-autoconnect: restart service to avoid dropping AEN
|
|
Content-type: text/plain
|
|
|
|
If another discovery log page change AEN is received while the
|
|
autoconnect service is already running for a previous AEN,
|
|
the autoconnect service is not being relaunched.
|
|
For example, if some of the entries in the log page are not reachable,
|
|
attempting to connect to them may take a long time before timing out,
|
|
so AENs received while waiting for the connections have no effect.
|
|
The AEN is effectively dropped: we ignore the new discovery log entries
|
|
and worse, the controller won't send more AENs because it's waiting
|
|
for the log page to be fetched in response to the previous AEN.
|
|
|
|
Use systemctl restart instead of systemctl start
|
|
to ensure nvme connect-all is run in response to each AEN.
|
|
If a previous instance of the service is already running,
|
|
it will be interrupted and the new log page will be fetched.
|
|
|
|
Fixes: 391d3b12248a ("nvme-cli: nvmf auto-connect scripts")
