registration
hi, in a 2 vcs node cluster with failover service when node a bring up the dg that comprises 5 disks,this node will write the registration and reservation key on every disk. at this moment on the disks is has not written the registration key of node b. right? if failover happens then what component deletes the reservation key of node a on disks? vxfend process?
Configure two Mount type resources of nfs FStype attribute using the same share
Hello: I am configuring a new Service Group in a VCS cluster. In this SG I have to add two Mount resources which represents two filesystems that are mounted from a NAS filler. The singular condition is that in the NAS, there is a share that will be mounted in two different mount points. These are the share and the two mount points: NAS-FIller:/path/of/share /mount1 NAS-Filler:/path/of/share /mount2 I have tested manually (mount -t nfs NAS-Filler:/path/of/share /mount1 and mount -t nfs NAS-Filler:/path/of/share /mount2) and it worked, but when I configure the two "Mount" type resources, and try to bing the SG online, the cluster only bring online the first mount, giving the following error in the second one: VCS ERROR V-16-10011-4078 Mount:P_BI_CARGA_FS:online:Block device NAS-Filler:/path/of/share is mounted on a different mount point /mount1 The block device attribute is the same in both resources. Thanks for your help Receive my best regards oolmedo
key registration and reservation
Hi, Let`s say we have 2 vcs nodes with fencing. hastop -local will leave the application running.The key registration and reservation on each disk in DG that was imported when vcs was started on node are still on the disks? If the service group failover then the key registration and reservation are deleted from disks by fencing driver?resource
