mounted Samba shares hang when laptop suspended

[ConradJones]

Hi

 

I normally have some shares mounted on my laptop (mint) to a file server (windows) if i close the lead and the laptop sits in the suspended/hibernated state the samba mounted shares hang the machine when i re open the lid and try to use them.

 

any ideas?

 

EDIT:

 

seems if a program has something open it locks it. not always easy to find the program with file open

You can use 'lsof' to find out what files a process has open. In this specific case, the +D option is probably what you want.

 

lsof +D /path/to/samba/mount/point

you could if it didn't hang like every thing else in sight.!

 

 

i found it quicker to manually work out what had the open file, turned out to be vmware workstation and an ISO on the software share.

Lazy unmount on sleep / remount? See script at https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/24864/comments/3

"If there are open files on the share we have problems again... but otherwise it works fine."

 

Last line!

Sorry, started googling for the script before your edit / other replies... the following could probably be popped into the stop function to check for locked files and kill the parent process causing the lock (altho you'd lose anything unsaved)

if [ '/usr/bin/smbstatus | grep DENY | wc -l' != "0" ]
then
fuser -m -k /{mount path}
fi

Googling around yields a few suggestions. Are you using wireless to access the samba server? Doesn't doing suspend vs hibernate make a difference?

yes

wireless

 

and @Marci i think killing the parent process maybe a little extreme,

[Geoff]

Ok, what wireless driver are you using?

[ConradJones]

its an

 

"Intel Corporation Centrino Advanced-N 6200 (rev 3e)"

 

lsmod - i'm not a 100% which one is the wireless card.

The linux driver for your Intel wifi card uses a binary firmware blob to operate. The bug causing the issue is within this binary firmware. Only intel can fix this properly. You can mitigate the situation by disabling the power saving features.

I would also strongly suggest you avoid hardware that doesn't have open specs where ever possible in future.

Unfortunately my primary concern when buying this laptop was that it had a real serial port which are as rare as rocking horse something these days.

[CyberNerd]

oops posted to wrong thread.

I find USB to serial quite good on linux as the drivers are generally built in

[ConradJones]

i was using windows at the time, but its also something to forget to put in the laptop bag, where as if your setting up a new switch you almost always get a normal serial lead with it.

 

i just find the usb to serial just one more thing which is unecessary as far as i am concerned, they've only removed the serial ports as a cost saving exercise.
