...running sun cluster 3.2 on solaris 10u3. We are using ufs/vxvm 4.1 as our shared file systems. However, I would like to migrate to HA-NFS on ZFS. Since there is no conversion process from UFS to ZFS other than copy, I would like to migrate on my own time. To do this I am planning to add a new zpool HAStoragePlus resource to my existing HA-NFS resource group. This way I can migrate data from my existing UFS to ZFS on my own time and the clients will not know the difference. I made sure that the zpool was available on both nodes of the cluster. I then created a new HAStoragePlus resource for the zpool. I up...

Hi All, Two and three-node clusters with SC3.2 and S10u3 (120011-14). If a node is rebooted when using SCSI3-PGR the node is not able to take the zpool by HAStoragePlus due to reservation conflict. SCSI2-PGRE is okay. Using the same SAN-LUN:s in a metaset (SVM) and HAStoragePlus works okay with PGR and PGRE. (both SMI and EFI-labled disks) If using scshutdown and restart all nodes then it will work. Also, (interesting) If I reboot a node and then run: update_drv...

Issues with ZFS and Sun Cluster If a cluster node crashes and HAStoragePlus resource group containing ZFS structure (ie. Zpool) is transitioned to a surviving node, the zpool import can cause the surviving node to panic. Zpool was obviously not exported in controlled fashion because of hard crash. Storage structure is - HW RAID protected LUN from array. Zpool build on sing...

...connecting to two T3B partner groups through a QLogic switch. All four bricks of the T3B are configured as RAID-5 with a hot spare. One brick from each pair is mirrored with VxVM 4.1 with a ufs file system on top of the mirror. I have mirrored the other two bricks via a Zpool. I have configured an HAStoragePlus resource for the datadg VxVM disk group and another one for the hazfs Zpool. Both are a part of my single nfs-rg. All machines are connected via 100MB switches. I have a small test program that was created to detect a particular "problem" that we were having. Its very simple and I will...

...e objective of my tests is: High Availability services with ZFS/NFS on solaris 10 using a two-node Sun Cluster. The scenarios are two: 1) Using "shared discs" (global devices). 2) Using "non-shared discs" (local devices). - The solution (1) is more simple, and we can use the HAStoragePlus resource type that we can found in the SC 3.2 installation. And as the data are "unique", i mean, in a failover/switchback scenario the "same" disc will be used in one or another host, the practical purpose is clear. The HOWTO for ZFS/NFS HA using shared discs (global devices...
