[libvirt] PATCH: Don't stop storage pools on daemon shutdown

Tearing a guest's storage out from under its feet on libvirtd shutdown is just as bad as tearing out its network :-) This patch removes the code which shuts down storage pool when the daemon shuts down. So NFS mounts stay around, LVM VGs remain active, and iSCSI connections remain logged in. When we then start up again, we happily detect that these resources are already running, and mark the pool as such Daniel diff --git a/src/storage_backend_iscsi.c b/src/storage_backend_iscsi.c --- a/src/storage_backend_iscsi.c +++ b/src/storage_backend_iscsi.c @@ -573,6 +573,7 @@ virStorageBackendISCSIStartPool(virConne virStoragePoolObjPtr pool) { char *portal = NULL; + char *session; if (pool->def->source.host.name == NULL) { virStorageReportError(conn, VIR_ERR_INTERNAL_ERROR, @@ -587,13 +588,17 @@ virStorageBackendISCSIStartPool(virConne return -1; } - if ((portal = virStorageBackendISCSIPortal(conn, pool)) == NULL) - return -1; - if (virStorageBackendISCSILogin(conn, pool, portal) < 0) { + if ((session = virStorageBackendISCSISession(conn, pool)) == NULL) { + if ((portal = virStorageBackendISCSIPortal(conn, pool)) == NULL) + return -1; + if (virStorageBackendISCSILogin(conn, pool, portal) < 0) { + VIR_FREE(portal); + return -1; + } VIR_FREE(portal); - return -1; + } else { + VIR_FREE(session); } - VIR_FREE(portal); return 0; } diff --git a/src/storage_driver.c b/src/storage_driver.c --- a/src/storage_driver.c +++ b/src/storage_driver.c @@ -241,32 +241,10 @@ storageDriverActive(void) { */ static int storageDriverShutdown(void) { - unsigned int i; - if (!driverState) return -1; storageDriverLock(driverState); - /* shutdown active pools */ - for (i = 0 ; i < driverState->pools.count ; i++) { - virStoragePoolObjPtr pool = driverState->pools.objs[i]; - - if (virStoragePoolObjIsActive(pool)) { - virStorageBackendPtr backend; - if ((backend = virStorageBackendForType(pool->def->type)) == NULL) { - storageLog("Missing backend"); - continue; - } - - if (backend->stopPool && - backend->stopPool(NULL, pool) < 0) { - virErrorPtr err = virGetLastError(); - storageLog("Failed to stop storage pool '%s': %s", - pool->def->name, err ? err->message : NULL); - } - virStoragePoolObjClearVols(pool); - } - } /* free inactive pools */ virStoragePoolObjListFree(&driverState->pools); -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
