[ovirt-users] Re: Ovirt 4.4.3 - Unable to start hosted engine

Hi, I have an ovirt 4.4.3 with 2 clusters, hosted engine and iscsi storage. First cluster, composed of 2 servers (host1 and host2), is dedicated to the hosted engine, the second cluster is for vms. Furthermore, there is a SAN with 3 luns: one for hosted engine storage, one for vms and one unused. My SAN is built on top of a pacemaker/drbd cluster with 2 nodes with a virtual ip used as iscsi Portal IP. Starting from today, after a failover of the iscsi cluster, I'm unable to start the hosted engine. It seems that there is some problem with storage. Actually I have only one node (host1) running in the cluster. It seems there is some lock on lvs, but I'm not sure of this. Here are some details about the problem: 1. iscsiadm -m session iSCSI Transport Class version 2.0-870 version 6.2.0.878-2 Target: iqn.2003-01.org.linux-iscsi.s1-node1.x8664:sn.2a734f67d5b1 (non-flash) Current Portal: 10.3.8.8:3260,1 Persistent Portal: 10.3.8.8:3260,1 ********** Interface: ********** Iface Name: default Iface Transport: tcp Iface Initiatorname: iqn.1994-05.com.redhat:4b668221d9a9 Iface IPaddress: 10.3.8.10 Iface HWaddress: default Iface Netdev: default SID: 1 iSCSI Connection State: LOGGED IN iSCSI Session State: LOGGED_IN Internal iscsid Session State: NO CHANGE ********* Timeouts: ********* Recovery Timeout: 5 Target Reset Timeout: 30 LUN Reset Timeout: 30 Abort Timeout: 15 ***** CHAP: ***** username: <empty> password: ******** username_in: <empty> password_in: ******** ************************ Negotiated iSCSI params: ************************ HeaderDigest: None DataDigest: None MaxRecvDataSegmentLength: 262144 MaxXmitDataSegmentLength: 262144 FirstBurstLength: 65536 MaxBurstLength: 262144 ImmediateData: Yes InitialR2T: Yes MaxOutstandingR2T: 1 ************************ Attached SCSI devices: ************************ Host Number: 7 State: running scsi7 Channel 00 Id 0 Lun: 0 Attached scsi disk sdb State: running scsi7 Channel 00 Id 0 Lun: 1 Attached scsi disk sdc State: running 2. vdsm.log errors: 2020-11-27 18:37:16,786+0100 INFO (jsonrpc/0) [api] FINISH getStats error=Virtual machine does not exist: {'vmId': 'f3a1194d-0632-43c6-8e12-7f22518cff87'} (api:129) ..... 2020-11-27 18:37:52,864+0100 INFO (jsonrpc/4) [vdsm.api] FINISH getVolumeInfo error=(-223, 'Sanlock resource read failure', 'Lease does not exist on storage') from=::1,60880, task_id=138a3615-d537-4e5f-a39c-335269ad0917 (api:52) 2020-11-27 18:37:52,864+0100 ERROR (jsonrpc/4) [storage.TaskManager.Task] (Task='138a3615-d537-4e5f-a39c-335269ad0917') Unexpected error (task:880) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/storage/task.py", line 887, in _run return fn(*args, **kargs) File "<decorator-gen-159>", line 2, in getVolumeInfo File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 50, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/storage/hsm.py", line 3142, in getVolumeInfo info = self._produce_volume(sdUUID, imgUUID, volUUID).getInfo() File "/usr/lib/python3.6/site-packages/vdsm/storage/volume.py", line 258, in getInfo leasestatus = self.getLeaseStatus() File "/usr/lib/python3.6/site-packages/vdsm/storage/volume.py", line 203, in getLeaseStatus self.volUUID) File "/usr/lib/python3.6/site-packages/vdsm/storage/sd.py", line 549, in inquireVolumeLease return self._domainLock.inquire(lease) File "/usr/lib/python3.6/site-packages/vdsm/storage/clusterlock.py", line 464, in inquire sector=self._block_size) sanlock.SanlockException: (-223, 'Sanlock resource read failure', 'Lease does not exist on storage') 2020-11-27 18:37:52,865+0100 INFO (jsonrpc/4) [storage.TaskManager.Task] (Task='138a3615-d537-4e5f-a39c-335269ad0917') aborting: Task is aborted: "value=(-223, 'Sanlock resource read failure', 'Lease does not exist on storage') abortedcode=100" (task:1190) 3. supervdsm.log MainProcess|monitor/de4645f::DEBUG::2020-11-27 18:41:25,286::commands::153::common.commands::(start) /usr/bin/taskset --cpu-list 0-11 /usr/sbin/dmsetup remove de4645fc--f379--4837--916b--a0c2b89927d9-dfa4e933--2b9c--4057--a4c5--aa4485b070e9 (cwd None) MainProcess|monitor/de4645f::DEBUG::2020-11-27 18:41:25,293::commands::98::common.commands::(run) FAILED: <err> = b'device-mapper: remove ioctl on de4645fc--f379--4837--916b--a0c2b89927d9-dfa4e933--2b9c--4057--a4c5--aa4485b070e9 failed: Device or resource busy\nCommand failed.\n';
