I am having problem with a backup solution for a small company.
One NFS Share (on a linux server in network)
5 HDDs (Mon - Fri)
Need to change them every day (attached via USB-Docking-Station),
then mount them from a client on the network and copy data.
Share is always in the same location, each HDD is always mounted under this share.
1) HDDs can't be umounted safely, device always busy once a client connected to the share. Even when there is nothing going on between server and client)
2) After changing HDD (example: swap out monday-hdd, put in tuesday-hdd) the client can't stay connected and use the newly put in HDD immediatly, I have to disconnect the share and reconnect it.
Is there a solution that would let me
a) just switch the disk every day on the server and the client without forced umount -l?
b) enable the client to just keep working with the connected share, without having to reconnect?
