Hello, all. Thank you for your advice.
This is my first experience with OMV. I have installed it on a Raspberry Pi 3+, attached a 32 GB flash drive, formated with an ext4 file system and assigned it as a share. I have created a user and then tried to mount the share without success from my linux client with
sudo mount -t ext4 192.168.1.102:/myTest /mnt/myTest/
The result is
"mount: special device 192.168.1.102:/myTest does not exist"
However, FTP works fine. I see the directory myTest in Nemo on Mint Linux and I can transfer files using FileZilla.
Please advise how to arrange for mounting the share.
