On the vsphere web client I have a strange problem with one of my datastores as it's displayed capacity is incorrect. Originaly it had 1TB of disk space. After I increased it's capacity on 1.4TB the next day it reverted back to 1TB.
The particular datastore in question (MSA_VD005) is located on HP MSA Storage. Originally it had 1TB of storage and from the MSA Array I increased it at 1.4TB, and after that I increased its capacity from the vsphere web client. (Standard procedure as i do always)
The very next day I've noticed a Datastore usage on disk
alarm in the web client. When I checked the datastore it had 1TB of space, as if I never increased it.
If I rescan all storage adapters on the hosts, it will show a correct value of ~1.4TB again but If i click the Refresh
button it will revert to 1TB again.
In order to verify all of this I logged in with SSH on one of the hosts and verified that the datastore size is indeed ~1.4. It is just that the vsphere web-client somehow pulls wrong value and generates warnings based on that value.
After rescan of the storage adapters:
After clicking the refresh button
Datastore size as displayed from the ESXi Shell
ESXi-5.5.0
.. Than we did an update of the two of the host with theESXi-5.5.0 Update 2
, but we were unable to update the third host because of several reasons (not worth mentioning). After a while we made the update of the third host, and the problem was gone for good. As a side note: I am the VMware admin and I am the Storage Admin :D – Spirit Mar 30 '15 at 9:38
