vSpehere 4.1.0 trigger a wrong datastore usage alarm

[Kastigar12]

Hello to all,

we have a problem with one datastore.

It is 1,45 TB, 794 GB provisioned, 787 GB free.

vSphere trigger a "datastore usage on disk" warning.

Alarm definition for Warning is set to 95% of disk space.

All other datastore does not have this issue, alarms will be or will be not triggered correct.

I would be pleased to get some clue about, how I can solved this issue.

Thanks!

have you tried to disable the alarm in question, then enable it again?  This  may fix the false positive.

Thank you so much. Disabling and enabling of definition does not remove alarm, but update capacity.

Now it is provisioned space 1,38 TB what is correct 95%.

It is strange, I have refreshed capacity before but it does not update it.

Thank you again!
