Ihad to replace a hard drive on our VMware 5.1 essentials server yesterday after it had failed. All seemed ok and after installing Dell open manage tools I restarted the server. Now after 24 hours I am getting an average latency reported as being 242ms and under hard ware monitor I can see that the RAID is still rebuilding. We have a 2 * 2TB HDD system on a Dell R515 server with the PERC H700 raid card based on RAID 1 due to the limitation of the number of HDDS. I would have expected to see latency increase during the rebuild as the HDD activity will be quite high but what I am concerned about is that it seems to have taken so long to rebuild.
Does this length of time seem normal to rebuild an array? (we are currently using about a quarter of the drive space)
