i have a filesystem listed on /dev/vda1, and the used space is growing fairly steadily - it was at 419MiB free a few minutes ago.
i have no idea what is accessing this device, and i am not allowed to unmount or delete it. what can i do to track down this device. i have checked lsusb but it is not there, and it is not listed as the source for any of my shares.
your help is greatly appreciated!
