Ovirt PXE boot wierdness
by Edson Manners 19 Jun '15

19 Jun '15

I'm running oVirt 3.5 newly installed with one test VM. I have the engine running on separate HW with eth0 being the management interface I have 2 compute nodes with eth0 being the management interface and eth1 having a vlan trunk with all of the VM networks If I install a guest from the CD image it all works fine and picks up an IP from the DHCP server. However if I switch the boot order to PXE first the gPXE DHCP request times out. Using tcpdump I can see the DHCP discovery packets get as far out as the physical trunk interfact eth1 (i.e. it gets past all of the virtual interfaces) but any other machines in that same VLAN don't see the DHCP request and neither does the DHCP server. My network settings are: Name: TestCluster External Provider: NO Network label: TC Enable VLAN tagging: 306 VM network: YES MTU: Default 1500 Under 'Setup Host Networks' Boot Protocol: DHCP Any ideas? -- [Any errors in spelling, tact or fact are transmission errors] - (Stolen from) Dag Wieers Edson Manners Systems Administrator, Research Computing Center FSU Information Technology Services Dirac Science Library., Room 150B Tallahassee, Florida 32303-4120

vdsm lvm filter
by Renout Gerrits 19 Jun '15

19 Jun '15

Hi All, I've got a setup with with ovirt and an equallogic iscsi. Im using the dell hit drivers. Install all good, after a reboot the storage won't come up. >From the vdsm logs i can see the volume groups can't be found. in the lvm vgs command the following filter is used: [ '\''r|.*|'\'' ] . If I change the LVMCONF_TEMPLATE in /usr/share/vdsm/storage/lvm.py and add the filter [ "a|^/dev/eql/ovirt.*|" ], the volume group is found and storage will be attached. How is the lvm filter constructed? And how can i make sure my volume groups are found without editing /usr/share/vdsm/storage/lvm.py? ==snippet vdsm.log 1== Thread-75::DEBUG::2015-06-11 13:25:03,496::lvm::291::Storage.Misc.excCmd::(cmd) /usr/bin/sudo -n /sbin/lvm vgs --config ' devices { preferred_names = ["^/dev/mapper/"] ignore_sus pended_devices=1 write_cache_state=0 disable_after_error_count=3 obtain_device_list_from_udev=1 filter = [ '\''r|.*|'\'' ] } global { locking_type=1 prioritise_write_locks=1 wait_for_locks=1 use_lvmetad=0 } backup { retain_min = 50 retain_days = 0 } ' --noheadings --units b --nosuffix --separator '|' --ignoreskippedcluster -o uuid,name,attr,size, free,extent_size,extent_count,free_count,tags,vg_mda_size,vg_mda_free,lv_count,pv_count,pv_name 9d551570-ef74-45b7-ba86-a908f1231ca8 (cwd None) Thread-75::DEBUG::2015-06-11 13:25:03,825::lvm::291::Storage.Misc.excCmd::(cmd) FAILED: <err> = ' Volume group "9d551570-ef74-45b7-ba86-a908f1231ca8" not found\n Skipping volum e group 9d551570-ef74-45b7-ba86-a908f1231ca8\n'; <rc> = 5 Thread-75::WARNING::2015-06-11 13:25:03,828::lvm::376::Storage.LVM::(_reloadvgs) lvm vgs failed: 5 [] [' Volume group "9d551570-ef74-45b7-ba86-a908f1231ca8" not found', ' Skipp ing volume group 9d551570-ef74-45b7-ba86-a908f1231ca8'] == ==snippet vdsm.log 2== storageRefresh::DEBUG::2015-06-11 13:37:13,602::lvm::292::Storage.Misc.excCmd::(cmd) /usr/bin/sudo -n /sbin/lvm lvs --config ' devices { preferred_names = ["^/dev/mapper/"] ignore_suspended_devices=1 write_cache_state=0 disable_after_error_count=3 obtain_device_list_from_udev=0 filter = [ "a|^/dev/eql/ovirt.*|" ] filter = [ '\''r|.*|'\'' ] } global { locking_type=1 prioritise_write_locks=1 wait_for_locks=1 use_lvmetad=0 } backup { retain_min = 50 retain_days = 0 } ' --noheadings --units b --nosuffix --separator '|' --ignoreskippedcluster -o uuid,name,vg_name,attr,size,seg_start_pe,devices,tags (cwd None) storageRefresh::DEBUG::2015-06-11 13:37:13,978::lvm::292::Storage.Misc.excCmd::(cmd) SUCCESS: <err> = ' WARNING: Ignoring duplicate config node: filter (seeking filter)\n Found duplicate PV FeScSs3Umv5wXtZCRvauf17sLaeQnS7e: using /dev/mapper/eql-0-af1ff6-8865608d7-3c400636c28555dd_b not /dev/mapper/eql-0-af1ff6-8865608d7-3c400636c28555dd_a\n Found duplicate PV FeScSs3Umv5wXtZCRvauf17sLaeQnS7e: using /dev/mapper/eql-0-af1ff6-8865608d7-3c400636c28555dd-ovirt-storage02 not /dev/mapper/eql-0-af1ff6-8865608d7-3c400636c28555dd_b\n Found duplicate PV hyyv4hWZiKT0UDdoDEyPZ5XrHc31hlTs: using /dev/mapper/eql-0-af1ff6-3cb5608d7-c1a0063645b5559b_b not /dev/mapper/eql-0-af1ff6-3cb5608d7-c1a0063645b5559b_a\n Found duplicate PV hyyv4hWZiKT0UDdoDEyPZ5XrHc31hlTs: using /dev/mapper/eql-0-af1ff6-3cb5608d7-c1a0063645b5559b-ovirt-storage01 not /dev/mapper/eql-0-af1ff6-3cb5608d7-c1a0063645b5559b_b\n'; <rc> = 0 == # rpm -qa |grep vdsm vdsm-jsonrpc-4.16.14-0.el6.noarch vdsm-xmlrpc-4.16.14-0.el6.noarch vdsm-python-zombiereaper-4.16.14-0.el6.noarch vdsm-python-4.16.14-0.el6.noarch vdsm-cli-4.16.14-0.el6.noarch vdsm-4.16.14-0.el6.x86_64 vdsm-yajsonrpc-4.16.14-0.el6.noarch Thanks!

This is a multi-part message in MIME format. --------------040506020505040804040504 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Hi! We just upgaded oVirt from 3.4 to 3.5 and now users cannot select the LDAP domain on the login screen. Only internal is available. Our LDAP server is actually a 389DS instance and we are using for authentication in oVirt without Kerberos. The existing setup has worked since the days of 3.2. When we try to validate the domain, we get [root@brda ~]# engine-manage-domains validate Error: Cannot authenticate user ovirt to domain guest.arnes.si, details: [LDAP: error code 32 - No Such Object]; nested exception is javax.naming.AuthenticationException: [LDAP: error code 32 - No Such Object] Failure while testing domain guest.arnes.si. Details: Cannot authenticate user to LDAP server. The LDAP log reports [18/Jun/2015:13:52:38 +0200] conn=3 op=0 BIND dn="uid=ovirt,ou=Peopledc=guest,dc=arnes,dc=si" method=128 version=3 As you can see there is a comma missing before "dc=guest,dc=arnes,dc=si". Before the upgrade the bind DN was generated properly as [18/Jun/2015:12:42:45 +0200] conn=10219 op=0 BIND dn="uid=ovirt,ou=People,dc=arnes,dc=si" method=128 version=3 This looks like a bug. Is there a quick fix we can do to fix this typo? We are also interested in knowing what is the correct way in 3.5 to add a domain that uses an LDAP server for its authentication source without Kerberos.
