Sorry, hit send by accident. More details : When I notice that the engine is down, if I type hosted-engine --vm-status on any hosts, it hangs and then writes a bunch of stuff saying it's down. If I type hosted-engine --vm-start on one of the hosts (Any), it just starts and gets back to business. hosted-engine --vm-status result : ovirt_hosted_engine_ha.lib.exceptions.RequestError: Failed to set storage domain FilesystemBackend, options {'dom_type': 'nfs3', 'sd_uuid': '3d67cf89-92de-428d-9714-e02aceae281e'}: Connection timed out Here's some logs from vdsm.log : Thread-98649::WARNING::2016-07-13 22:54:04,418::fileSD::749::Storage.scanDomains::(collectMetaFiles) Could not collect metadata file for domain path /rhev/data-center/mnt/engine.domain.com:_var_lib_exports_iso Traceback (most recent call last): File "/usr/share/vdsm/storage/fileSD.py", line 735, in collectMetaFiles sd.DOMAIN_META_DATA)) File "/usr/share/vdsm/storage/outOfProcess.py", line 121, in glob return self._iop.glob(pattern) File "/usr/lib/python2.7/site-packages/ioprocess/__init__.py", line 534, in glob return self._sendCommand("glob", {"pattern": pattern}, self.timeout) File "/usr/lib/python2.7/site-packages/ioprocess/__init__.py", line 419, in _sendCommand raise Timeout(os.strerror(errno.ETIMEDOUT)) Timeout: Connection timed out Thread-63::ERROR::2016-07-13 22:54:04,418::sdc::145::Storage.StorageDomainCache::(_findDomain) domain bd73cb0f-bb9c-432a-90ee-a32757a8bc10 not found Thread-98498::ERROR::2016-07-13 22:50:33,895::brokerlink::279::ovirt_hosted_engine_ha.lib.brokerlink.BrokerLink::(_communicate) Connection closed: Connection timed out Thread-98498::ERROR::2016-07-13 22:50:33,895::API::1871::vds::(_getHaInfo) failed to retrieve Hosted Engine HA info Traceback (most recent call last): File "/usr/share/vdsm/API.py", line 1851, in _getHaInfo stats = instance.get_all_stats() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 103, in get_all_stats self._configure_broker_conn(broker) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 180, in _configure_broker_conn dom_type=dom_type) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/brokerlink.py", line 176, in set_storage_domain .format(sd_type, options, e)) RequestError: Failed to set storage domain FilesystemBackend, options {'dom_type': 'nfs3', 'sd_uuid': '3d67cf89-92de-428d-9714-e02aceae281e'}: Connection timed out Thanks for your input, and even if it's a storage problem, if it's to happen, how can I force it to restart the engine? At first I tought it was a split-brain issue so I added a 3rd host but I still have the same problem. On Wed, Jul 13, 2016 at 11:13 PM, Mark Gagnon <rhubarbe@gmail.com> wrote:

Hi, We have a 3 hosted-engine nodes setup using 2 NFS3 shares on which the engine keeps crashing every few days.

Looking at VDSM logs, it looks like a storage problem but I'm wondering why don't they restart the engine?
