We have a Windows 2008 R2 server with a RAID 5 array. It is configured into one virtual disk. This disk is split into 2 partitions, C: for the OS and applications and D: for some file shares.
This weekend I got a call that employees could not access the file shares. I restarted the server remotely and that did not help. When I went into Disk Management I found that the logical partition that was D: was gone. I have since recreated it and restored the data but would like to know what could have caused the partition to go missing. I checked the controller logs and Windows event logs and nothing stands out.
Does anyone have any ideas?
