Hi,
We have a Dell PowerEdge R440 server running VMware ESXi 6.7 in our company.
It's configuration has the OS running in a SD card and a 3 drives in RAID 5 as the storage for the VMs.
As we added more VMs (we had 5) the performance got really bad, so we decided to do a disk upgrade.
After measuring the performance of that server with Live Optics, we decided to add another drive and have RAID 10 instead of RAID 5.
The plan was:
1) Backup all the VMs on the Dell server - Done
2) Erase the VMs on that server - Done
3) Unmount and delete the LocalStorage-1 datastore on VMware- Not working
4) Break the RAID 5 running with 3 disks on the Dell server
5) Turn off the server and add the new drive to the Dell server
6) Build the RAID 10 running with 4 disks on the Dell server
7) Create the LocalStorage-1 datastore on VMware
8) Restore all the VMs to the Dell server
However, when I tried to unmount or delete the LocalStorage-1, it simply wouldn't work.
Inspecting the configuration with more details, I found 3 devices: the SD card, the RAID 5, and a 18GB one that I don't know what is.
If I try to delete the current partition on the RAID 5 device it also doesn't work.
If I browse the local storage, I can see 2 folders, but can delete just the .locker one (which returns if I reboot the server)
So, it seems that there is something writing to that local storage and for that reason I can't delete it.
However, I already looked at all the configurations and couldn't find what that was.
The only one I found is an advanced setting that still points to that datastore, but it doesn't accept me to change its setting and point to a different location
Does anybody have any suggestion?
Thanks,
Carlos
