Hello! I am observing a strange situation. I created volume 6.1 Gb Thick Provision with Autogrow Mode enable and LUN fixed size 6GB Thick Provision for the VMs to guarantee space for the VMs. The LUN size does not change, but the volume on which this LUN is located is growing in size all the time. On the LUN, virtual machines occupy only 720 Gb out of 6 TB (see attach file LUN.jpg). But volume already takes 6.81 TB and only 160 Gb is free on it! (see attach file Volume1.jpg) It means that the metadata is 650 GB! 720 Gb users data and 650 GB metadata - this is more than strange!!! How can I predict volume growth? Can you accurately calculate the maximum size the volume will have if it has a 6TB Thick Provision LUN?

Hi All, I have a few CIFS shares configured, I do see that the " Max Users" attribute value is set to a very high number. Trying to gather the average number of concurrent users over a period of time. I am running Clustered Data ONTAP 8.x and hence trying to figure out a way via CLI or ONTAPI interface so that it can be gathered programmatically or via script. Would like to monitor this info on regular basis. For example: On an average (or 95th percentile) how many concurrent users were seen over the last 1 week or 1 month? Thanks in advance!

Environment: NetApp FAS and Linux Suse Desc: Added 100gb to an exisitng 100gb lun, but at server end this new 100gb is still not taken over. Lun size: 200GB Used size 70GB Normally Shrinking a lun requires data migration to a new resized LUN, but if we already know the new blocks are free, and we need to say reclain 90GB out of the new unused 100GB - Is it possible to do it directly on netApp? What will netapp reclaim first - the empty blocks of the lun (seeing from netapp perspective as it only shows 70GB in use 130gb free)?

I want to modify the ATTO bridge 7500N FCConnMode, but I am not sure whether to disable the corresponding FC switch port. After modifying the FCConnMode parameter, enable the switch port. Is this step necessary? I do not know which engineer has the experience to modify this parameter, whether the modification of this parameter will cause link interruption or no impact, hope to get a reply!

We just attempted to deploy the 90-day trial version of the ONTAP Select 9.9.1 single-node cluster on VMware ESXi 7.0.2 and it is failing to startup. I attached a screenshot of the WARNINGS/ERRORS.
