MSMQ Outgoing Queues referencing failed EV server - using Building Blocks for High Availability
Hi Everyone We make use of Building Blocks to build High Availability in our EV environment. We have come across a peculiar problem and wanted to know if anyone here has noted a similar issue. Scenario: We are in the archiving schedule and there are (say) 5 EV Mailbox Archiving Servers archiving 5 Exchange Servers. There are cross-references across EV and Exchange Servers i.e. the Storage Service for an archive is on an EV server other than the one which is running the Archival Task. Problem: If an EV Mailbox Archiving Servers fails, we use Building Blocks to quickly bring up services on a standby server by running Update Service Locations. However, we notice that items are still in archive pending state in user mailboxes being archived by other EV Servers. New items are also going into archive pending state across all user mailboxes. Analysis: We have already run a flushdns (or Clear-DNSClientCache in Powershell) across all EV servers. In the MSMQ Outgoing Queues, we noticed that there are queues which still resolve to the old failed servers and are in Failed to Connect or Waiting to Connect state, since MSMQ does not resolve to the EV aliases but the EV server hostnames. Solution: To resolve the issue, we need to add a host file entry resolving thehostname of the failed server to the IP address of the now active server and restart the storage/taskcontroller service. Has anyone of you come across a similar situation? We wish to avoid making host file entries and make thefailover process seamless.
Understanding RestartLimit for non critical ressource
Hello, we have some trouble with our oracle listener process. sometimes the listener is killed by vcs. We dont know why. xxx VCS ERROR V-16-2-13027 (node1) Resource(lsnr-ORADB1) - monitor procedure did not complete within the expected time. xxx VCS ERROR V-16-2-13210 (node1) Agent is calling clean for resource(lsnr-ORADB1) because 4 successive invocations of the monitor procedure did not complete within the expected time. xxx VCS NOTICE V-16-20002-42 (node1) Netlsnr:lsnr-ORADB1:clean:Listener(LISTENER) kill TERM 2342 xxx VCS INFO V-16-2-13068 (node1) Resource(lsnr-ORADB1) - clean completed successfully. xxx VCS INFO V-16-2-13026 (node1) Resource(lsnr-ORADB1) - monitor procedure finished successfully after failing to complete within the expected time for (4) consecutive times. xxx VCS INFO V-16-1-10307 Resource lsnr-ORADB1 (Owner: unknown, Group: ORADB1) is offline on node1 (Not initiated by VCS) However,Resource(lsnr-ORADB1) is set to non-critical, to prevent an failover. I'll now set an RestartLimit forResource(lsnr-ORADB1) to let the cluster try to restart the listener, but what happen if this failed?Will the Ressouce still staying offline or initiate the cluster an failover for the whole ResourceGroup? thanks in advance for any help!
deleting rlink that's having "secondary_config_err" flag
hello, in my VCS global cluster my ORAGrp resource group is partially online since my rvgres is offline, i am suspecting the issue in the below rlink. i am trying to dissociate thi rlink(below:rlk_sys1-DB-rep_DB_r) and dettach it in order to delete it but i am not able to succeed. below are some output from the system. root@sys2# vxprint -P Disk group: DBhrDG TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 rl rlk_sys1-DB-rep_DB_r DB_rvg CONNECT - - ACTIVE - - rl rlk_sys1-rep_DB-rvg DB-rvg ENABLED - - PAUSE - - root@sys2# vxrlink -g DBhrDG dis rlk_sys1-rep_DB-rvg VxVM VVR vxrlink ERROR V-5-1-3520 Rlink rlk_sys1-rep_DB-rvg can not be dissociated if it is attached root@sys2# vxrlink -g DBhrDG det rlk_sys1-rep_DB-rvg VxVM VVR vxrlink ERROR V-5-1-10128 Operation not allowed with attached rlinks root@sys2# vxedit -g DBhrDG rm rlk_sys1-rep_DB-rvg VxVM vxedit ERROR V-5-1-3540 Rlink rlk_sys1-rep_DB-rvg is not disabled, use -f flag root@sys2# vxedit -g DBhrDG -f rm rlk_sys1-rep_DB-rvg VxVM vxedit ERROR V-5-1-3541 Rlink rlk_sys1-rep_DB-rvg is not dissociated root@sys2# vxprint -Vl Disk group: DBhrDG Rvg: DB-rvg info: rid=0.1317 version=0 rvg_version=41 last_tag=11 state: state=CLEAN kernel=DISABLED assoc: datavols=(none) srl=(none) rlinks=rlk_sys1-rep_DB-rvg exports=(none) vsets=(none) att: rlinks=rlk_sys1-rep_DB-rvg flags: closed secondary disabled detached passthru logging device: minor=26012 bdev=343/26012 cdev=343/26012 path=/dev/vx/dsk/DBhrDG/DB-rvg perms: user=root group=root mode=0600 Rvg: DB_rvg info: rid=0.1386 version=13 rvg_version=41 last_tag=12 state: state=ACTIVE kernel=ENABLED assoc: datavols=sys1_DB_Process,sys1_DB_Script,... srl=sys1_DB_SRL rlinks=rlk_sys1-DB-rep_DB_r exports=(none) vsets=(none) att: rlinks=rlk_sys1-DB-rep_DB_r flags: closed secondary enabled attached logging device: minor=26014 bdev=343/26014 cdev=343/26014 path=/dev/vx/dsk/DBhrDG/DB_rvg perms: user=root group=root mode=0600 please advise regards
Windows 2012 R2 Failover cluster and SF Volume Manager Disk Group
Hi, I just found this article and its quite the problem I'm facing right now: https://www-secure.symantec.com/connect/forums/one-cooperation-issue-about-windows-2012-r2-failover-cluster-and-sf-cluster-shared-disk-group I created a new Windows Server 2012 R2 Failover Cluster with several mirrored Disks in DynamicDiskGroups in StorageFoundation. As a next step, I wanted to add the Diskgroups from SF as a Ressource to my Failover Roles. Actual scenario: Cluster Role Name: C0002Z DiskGroupName in SF: DG_C0002Z_1 Then I added a Ressource to the Cluster Role via Add Resource -> More Resources -> Volume Manager Disk Group I changed the Name of the VMDG in "General" to "DG_C0002Z_1", apply, ok. Then I wanted to add the Name of the DiskGroup in Properties -> Properties -> DiskGroupName of the VMDG to "DG_C0002Z_1". And thats where I dont get any further. It doesn't matter which Name I want to enter into DiskGroupName, theres always this Error: There was an error saving properties for 'DG_C0002Z_1'. Failed to execute control code '20971654'. Error Code: 0x800700a0 One or more arguments are not correct I also tried to enter Names without special characters but that doesnt help eather. Do you have any Idea how to fix or bypass this issue? Thanks
