Hi, no workarounds so far. But my mysql db is using default options and also runs in a virtual machine – so I suspect it just needs some tweaking. I’m going to change few parameters during this week. I’ll post the results to mailing list if it works.

Any pointers on a workaround?

I've recently upgraded from v4.4 to 4.6. As part of the upgrade, we decided to create a new db using MySQL. The configurations ran smooth, all nodes and datastores are being monitored without issues but when I tried to upload a ttylinux image for testing, sunstone didn't show the image uploaded on the list. As if it wasn' t even there. I ran the #oneimage list command, and there's no image there either. So I tried uploading again, while I checked the oned.log. I then tried to upload other images. I have OpenNebula front end installed on a host, several other nodes that are speciffic for running the VMs and a NAS with 20TB that holds the datastores. While I was uploading an ubuntu image (20GB), I checked the transmition rate on the network and I was supprised to see that the traffic between my desktop (where I was uploading from) and the frontend was very heavy, but the datastore was not recieving the image I was uploading. Interestingly, the log showed this error: Tue Sep 9 16:20:04 2014 [ONE][E]: SQL command was: REPLACE INTO datastore_pool (oid, name, body, uid, gid, owner_u, group_u, other_u, cid) VALUES (0,'system','<DATASTORE><ID>0</ID><UID>0</UID><GID>0</GID><UNAME>oneadmin</UNAME><GNAME>oneadmin</GNAME><NAME>system</NAME><PERMISSIONS><OWNER_U>1</OWNER_U><OWNER_M>1</OWNER_M><OWNER_A>0</OWNER_A><GROUP_U>1</GROUP_U><GROUP_M>0</GROUP_M><GROUP_A>0</GROUP_A><OTHER_U>0</OTHER_U><OTHER_M>0</OTHER_M><OTHER_A>0</OTHER_A></PERMISSIONS><DS_MAD><![CDATA[-]]></DS_MAD><TM_MAD><![CDATA[shared]]></TM_MAD><BASE_PATH><![CDATA[/var/lib/one//datastores/0]]></BASE_PATH><TYPE>1</TYPE><DISK_TYPE>0</DISK_TYPE><CLUSTER_ID>-1</CLUSTER_ID><CLUSTER></CLUSTER><TOTAL_MB>9461612</TOTAL_MB><FREE_MB>8956832</FREE_MB><USED_MB>1</USED_MB><IMAGES></IMAGES><TEMPLATE><BASE_PATH><![CDATA[/var/lib/one//datastores/]]></BASE_PATH><SHARED><![CDATA[YES]]></SHARED><TM_MAD><![CDATA[shared]]></TM_MAD><TYPE><![CDATA[SYSTEM_DS]]></TYPE></TEMPLATE></DATASTORE>',0,0,1,1,0,-1), error 1213 : Deadlock found when trying to get lock; try restarting transaction /*******************************************************/ I leave down here a copy of my oned.conf /*******************************************************/ LOG = [ system = "file", debug_level = 3 ] MONITORING_INTERVAL = 60 MONITORING_THREADS = 50 SCRIPTS_REMOTE_DIR=/var/tmp/one PORT = 2633 DB = [ backend = "mysql", server = "localhost", port = 0, user = "oneadmin", passwd = "__________________", db_name = "opennebula" ] VNC_BASE_PORT = 5900 FEDERATION = [ MODE = "STANDALONE", ZONE_ID = 0, MASTER_ONED = "" ] NETWORK_SIZE = 254 MAC_PREFIX = "02:00" DATASTORE_CAPACITY_CHECK = "yes" DEFAULT_IMAGE_TYPE = "OS" DEFAULT_DEVICE_PREFIX = "hd" DEFAULT_CDROM_DEVICE_PREFIX = "vd" IM_MAD = [ name = "collectd", executable = "collectd", arguments = "-p 4124 -f 5 -t 50 -i 20" ] IM_MAD = [ name = "kvm", executable = "one_im_ssh", arguments = "-r 3 -t 15 kvm" ] VM_MAD = [ name = "kvm", executable = "one_vmm_exec", arguments = "-t 15 -r 0 kvm", default = "vmm_exec/vmm_exec_kvm.conf", type = "kvm" ] TM_MAD = [ executable = "one_tm", arguments = "-t 15 -d dummy,lvm,shared,fs_lvm,qcow2,ssh,vmfs,ceph" ] DATASTORE_MAD = [ executable = "one_datastore", arguments = "-t 15 -d dummy,fs,vmfs,lvm,ceph" ] HM_MAD = [ executable = "one_hm" ] AUTH_MAD = [ executable = "one_auth_mad", authn = "ssh,x509,ldap,server_cipher,server_x509" ] SESSION_EXPIRATION_TIME = 900 DEFAULT_UMASK = 177 VM_RESTRICTED_ATTR = "CONTEXT/FILES" VM_RESTRICTED_ATTR = "NIC/MAC" VM_RESTRICTED_ATTR = "NIC/VLAN_ID" VM_RESTRICTED_ATTR = "NIC/BRIDGE" IMAGE_RESTRICTED_ATTR = "SOURCE" INHERIT_DATASTORE_ATTR = "CEPH_HOST" INHERIT_DATASTORE_ATTR = "CEPH_SECRET" INHERIT_DATASTORE_ATTR = "CEPH_USER" INHERIT_DATASTORE_ATTR = "RBD_FORMAT" INHERIT_DATASTORE_ATTR = "GLUSTER_HOST" INHERIT_DATASTORE_ATTR = "GLUSTER_VOLUME" INHERIT_VNET_ATTR = "VLAN_TAGGED_ID" TM_MAD_CONF = [ name = "dummy", ln_target = "NONE", clone_target = "SYSTEM", shared = "yes" ] TM_MAD_CONF = [ name = "lvm", ln_target = "NONE", clone_target = "SELF", shared = "yes" ] TM_MAD_CONF = [ name = "shared", ln_target = "NONE", clone_target = "SYSTEM", shared = "yes" ] TM_MAD_CONF = [ name = "fs_lvm", ln_target = "SYSTEM", clone_target = "SYSTEM", shared="yes" ] TM_MAD_CONF = [ name = "qcow2", ln_target = "NONE", clone_target = "SYSTEM", shared = "yes" ] TM_MAD_CONF = [ name = "ssh", ln_target = "SYSTEM", clone_target = "SYSTEM", shared = "no" ] TM_MAD_CONF = [ name = "vmfs", ln_target = "NONE", clone_target= "SYSTEM", shared = "yes" ] TM_MAD_CONF = [ name = "ceph", ln_target = "NONE", clone_target = "SELF", shared = "yes" ] /**********************************************************/ best regards galimba -- [Image removed by sender.] -- [Image removed by sender.] ________________________________ This e-mail and any attachment is for authorised use by the intended recipient(s) only.
