"Parity check in progress" warning in ESXi 5

warnings storage vmware esxi

After connecting 8 hard drives to RAID5 and doing Fast initialization my ESXi shows 8 warnings that say "Parity check in progress". In old vmware forums I found that maybe RAID is still building, but why then am I allowed to use the datastore?

any ideas what this warning means and how to get rid of it?

thanks

That's correct, the raid is still building. It might take a couple of hours, depending on:

  • the raid controller,
  • disk speed
  • disk size.

If your raid controller doesn't have write back enabled (or doesn't support it), that time will be quite longer.
