The is one question regarding removing the failed this on vSAN.
one of my disk on one ESXi host has been failed and I replaced it with a new disk, and configured the RAID 0 to re enable the logical drive.
Now it shows the old disk as absent and I want to remove it from disk group but it says disk cannot be removed.
I put the esxi into the maintenance mode, still the problem stays the same.
Can anyone help on this?
Hi @miladmeh8, is deduplication enabled or not? As detailed in this KB, there are different steps to follow if this is or not enabled: https://kb.vmware.com/s/article/2150593 whereby if it is then the whole disk group needs to be re-created due to the deduplication across all disks in that disk group.
@miladmeh8 If you only tried via the vSphere UI Disk Management page then it might be disallowing remove due being unable to do remove precheck on it, if that is the case I would just remove the remaining CMMDS reference to it via the CLI e.g.:
Get the UUID (e.g. will see all in-use disks naa/t10/eui reference but one entry with just a UUID in format 8-4-4-4-12 digits):
# vdq -Hi
# esxcli vsan storage remove -u UUIDhere
