Mounting across network

steve007 · 09-07-2005, 06:06 AM

Hello,
I have a little tiny problem. I have got a network share mounted to a folder on my Fedora Core system, all works fine... however, i do have one problem... and that is, how do i get the mount back if the network shared PC restarts or turns off?
If the share is powered down then the Fedora System crashes when accessing the folder, presumably because its trying to access a mounted volume, the folder can not be deleted because it keeps crashing so therefore i have to restart the Fedora machine, load up the other pc and re mount it (I could probably get it to mount on boot up but this Fedora system is not supposed to be reset as its acting as a PDC at the moment).

is there a way i can get my Fedora Core system periodically check if the network share is still available? If it's not available then dont do anything, if it is can i get it to remount it once its available again?

of course my obvious solution is to leave the network share pc turned on i figured that, but if there is a hardware failure or power surge in it... then its unavoidable.

If you could let me know if this is possible or not id greatly appreciate it.

Thanks.

It is possible.
I would script a solution that allows you to touch a file on that share. If it fails, remove the entry from /etc/xtab, and restart nfs (service nfs restart).

Just a thought:

Code:

#!/usr/bin/perl -w

my $exit = system("touch /path/to/mount/filename");
unless($exit == 0){
    system("cat /etc/xtab | grep -v /path/to/mount > /etc/xtab");
    system("service nfs restart");
    system("mount 10.0.0.1:/path/to/mount /mountpoint");
}

Make that a cron job running every 2 minutes

Substitute /path/to/mount to the mountpoint you are using in the first system call.
Same with the second.
Sub the nfs server info and mountpoint in the forth one.
Save the file, and chmod +x to be able to execute.

Hello,
I have edited your code and run it, but its gives me an error saying unexpected token near '(' on line two, then displays line two as having an error...
this is my code

Code:

#!/usr/bin/perl -w
my $exit = system("touch /disks/Disk-1/.testmount");
unless($exit == 0){
    system("cat /etc/xtab | grep -v /disks/Disk-1 > /etc/xtab");
    system("cat /etc/xtab | grep -v /disks/Disk-2 > /etc/xtab");    
    system("service nfs restart");

    system("mount -t -p mypass smbfs 192.168.1.15:/Disk-1 /disks/Disk-1");
    system("mount -t -p mypass smbfs 192.168.1.15:/Disk-2 /disks/Disk-2");

}

what is wrong with that on line two? I'ts the same as yours, I am not a perl programmer so i have no idea what is wrong with the code... any help would be most appreciated

cheers

firstly matey its quite rude to bump up your post by just posting again with a begging question offing no more insight to your problem. people take time out of their own lives to give somethign back with no personal benifit for them. nobody gets paid for answering your questions so sending a message demanding help when theres been no perly for only a day is quite ungrateful

anyway

if your not a perl programmer try and learn some? - linux is all about learning

i've just run the script and its runs fine with the exception of the lack of all your specific directories

you sure you've got perl installed?

look at this,
5 minutes googling gets you this
google for 'nfs server outage unmount'
first link is
http://www.netapp.com/tech_library/ftp/3183.pdf

section 4.3 might be what you want?
did you read the nfs man pages?
