2008 Server reports files on Shared LUN are Corrupted
Hello. I am trying to build a two node SQL 2008 Server x64 Cluster. I was having trouble getting the two servers to access the AX4 but that has been solved, thanks to "chiodp" in a recent post to this forum.
However, After setting up the two servers (they are not yet a cluster) and providing them with access to the shared LUN on the AX4, they report that the files residing on the shared LUN are corrupted. My build has changed a little bit after doing more reading:
Device: AX4-5i with SAS drives. (Working properly.) FLARE: 02.23.050.5.703 Virtual Disk/Shared LUN: 60GB RAID5 (name: SHARELUN1) 2 Physical DELL Servers: Windows 2008 SP2 Enterprise x64 / SQL 2008 x64 (All updates/drivers applied.) Each server has a 2-port Broadcom iSCSI PCIe-4x card. (Working properly.) Navisphere Server Utility 22.214.171.124.99 PowerPath 5.3.b311
Done so far for both servers. 1. Installed Windows Server 2008 Ent x64. / Joined servers to Domain 2. iSCSI Initiator Service is ON. 3. Installed Navisphere Server Utility (Defaults selected and configured access to the AX4 and logged in.) 4. Installed Powerpath 5.3; Reboot. 5. On the AX4 in Navisphere Express: Selected Virt Disk/LUN; Assigned both servers to the LUN. 6. Disk is now visible on both nodes. I ran diskmgmt.msc on each node and initialized disk. 7. Formatted disk on each node; Assigned drive letter "F:\" on both servers. 8. I copied test files to the new "F:\" drive on both servers. 9. Reboot. After reboot, servers report files on F:\ are corrupt when I try to access them.

Hi Again , the corruption is normal expect behavior , you have no cluster service setup . You need to have the cluster service enable to avoid the data corruption . Cluster service will install a service Clustdisk this will manage the lock between the two nodes and avoid any corruption on the share resource . You need to proceed in this way :
- turn off one node - Install the cluster service on the other node - configure the cluster service and the share resources - Power on the second node and join the cluster
