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. 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!
