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 single HW LUN. Zpool created on a full device (zpool create HAzpool c1t8d0s2). No RAID-Z configured.
I was under the impression that ZFS was always maintained in a perpetually consistent state. Panic of surving node appears to be related to some form of silent corruption in ZFS. But I thought the whole design of ZFS was to prevent this very thing. Is RAID-Z required to achieve this resiliency? ZFS is officially supported under Sun Cluster but this situation concerns me greatly because the whole purpose of a cluster is undermined if a single resource group using HA ZFS causes a panic on import. The effect could bring the whole cluster down. Has anyone got any thoughts, comments or similar experiences on this. thx -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
