Need help accessing data on FreeNAS 9.3

[Euclides]

Dear Sirs, good morning!
I would like you to help me to make visible in freeNAS 9.3 the datastore where I have my data.
datastore/SAN-IMAGENS
datastore/SAN-VOLUME

As per the attached images.

Your 2 entries appear to be zVolumes. This is a type of block storage intended to be supplied by iSCSI or NFS to client servers. They would not normally be mountable on the local NAS device.

So, you would have to find the client servers that used the zVolumes. That should tell you the file system used inside the zVolumes and how to access them.
