Hi All,
I have recently been having some issues with an LIS 9260-8i RAID adaptor running in a Dell T430 server. The card manages 4 disks in a RAID 6 array containing a single VMFS datastore. One of the VDMK files in the store is mounted as a drive to a Windows server and shared for backup purposes. When I write a reasonable amount of data to the drive (200MB as a machine backup), the adaptor seemingly disappears from the host, taking the data-store with it and causing Windows VM server to fail. Rebooting the host resolves the issue and there doesn't seem to be a problem unless you write large amounts of data.
Anyhow, I decided to update firmware on the Dell server and the LIS card, and just to be sure, I also decided to install a fresh version of ESXi v6.7 just to ensure that ESXi was in a known reasonable state. This is the Dell OEM ESXi version. Eventually, everything is back up and running; however, I went to open some folders on the datastore an ended up with a Pink Screen of death (see attachment).
I am guessing that the adaptor failure has cause some datastore corruption. This appears to be with regard to some folders which contain some VM guests that I do not use a great deal, but if I can salvage anything, that would be great. If I do not navigate to those folders, ESXi seems happy.
Is there any way to repair file/folders on the VMFS datastore?
