Is there a way to check if datastore is use by the ESXi system?

[kendzi87]

I am looking for somehow counter, reference or variable for example if let's say isBusy=1 datastore is in use and cannot be deleted if isBusy=0 then it can be safely deleted (this is for automation purpose).

I am looking for these because off  error : "Error: The reason is Call "HostDatastoreSystem.RemoveDatastore" for object "ha-datastoresystem" on ESXi "10.10.1.186" failed.
Cannot remove datastore 'Datastore Name: datastore1 VMFS uuid: 5616aa3a-5fa106ea-b830-6805ca3819fe' because file system is busy."

you can check in your script if the filesystem is mounted by using the command : esxcli storage filesystem list

example: check for the "mounted" value

[root@F22-Raptor:~] esxcli storage filesystem list

Mount Point                                        Volume Name            UUID                                 Mounted  Type            Size          Free

Try the lsof command to check of any files are open on that datastore, e.g.

lsof | grep UUID

This will list any ESX host processes writing to that datastore.

Sorry for long response. Unfortunately both answers not helped

Try this

Display hosts which are actively using a volume

~ # vmkfstools –activehosts /vmfs/volumes/VNX-20
Found 1 actively heartbeating hosts on volume '/vmfs/volumes/VNX-20'
(1): MAC address 98:4b:e1:0a:24:d8

This option will show the management interface MAC address of any hosts which is actively using a datastore. This is exactly what vSphere HA uses to see if a host is still active. It walks through the heartbeat records on the VMFS and checks which are active. This might take a few moments to run as it has to wait for the heartbeat record to age and refresh. It then it displays the MAC address of the owner.

I tried your command:

vmkfstools –activehosts /vmfs/volumes/VNX-20

I assume after VNX-20 is your datastore. I used mine but I am getting:

"Extra arguments at the end of the command line."

[battybishop]

Sorry missed a - command should be vmkfstools --activehosts vmfspath

thanks I am going to check it
