I export a folder to remote hosts by configuring the /etc/export file this way in the NFS server:
and start the NFS daemon with this command:
In the NFS client, I am issuing this command to mount the remote folder locally:
mount -t nfs -o ro,bg,soft,intr,timeo=5,retrans=5,actimeo=10,retry=5 nfsServerIp:/remoteFolder localFolder
I have noticed that, in the NFS client, the mount.nfs command is using a serial port (e.g. ttyS3) by filtering the lsof output. Is this OK?
Furthermore, that serial port shares IRQ with another three serial ports. In the same one the mount.nfs command is using, I am trying to communicate to an external device and this communication is curiously failing sometimes. I have configured /etc/serial.conf with this parameters:
/dev/ttyS0 uart 16550A port 0x3F8 irq 4 /dev/ttyS1 uart 16550A port 0x2F8 irq 3 /dev/ttyS2 uart 16550A port 0x3E8 irq 11 /dev/ttyS3 uart 16550A port 0x2E8 irq 11
Is it possible to solve this problem? Can I force mount.nfs to use another serial port?
Thanks in advance.
