Failed to unlink the directory '/export/pi' -> apply config

davidh2k · 23. September 2013

Hey Guys,

I'm cleaning up my system from some test and did it nicely all together. When I now try to apply the config I get the following error: (cannot unlink an NFS share)

Code

Failed to unlink the directory '/export/pi'


Error #6000: exception 'OMVException' with message 'Failed to unlink the directory '/export/pi'' in /usr/share/openmediavault/engined/module/fstab.inc:122 Stack trace: #0 [internal function]: OMVModuleFsTab->deleteEntry(Array) #1 /usr/share/php/openmediavault/module.inc(136): call_user_func_array(Array, Array) #2 /usr/share/openmediavault/engined/module/fstab.inc(52): OMVModuleAbstract->execTasks('delete') #3 /usr/share/openmediavault/engined/rpc/config.inc(148): OMVModuleFsTab->stopService() #4 [internal function]: OMVRpcServiceConfig->applyChanges(Array, Array) #5 /usr/share/php/openmediavault/rpcservice.inc(125): call_user_func_array(Array, Array) #6 /usr/share/openmediavault/engined/rpc/config.inc(231): OMVRpcServiceAbstract->callMethod('applyChanges', Array, Array) #7 [internal function]: OMVRpcServiceConfig->applyChangesBg(Array, Array) #8 /usr/share/php/openmediavault/rpcservice.inc(125): call_user_func_array(Array, Array) #9 /usr/share/php/openmediavault/rpc.inc(62): OMVRpcServiceAbstract->callMethod('applyChangesBg', Array, Array) #10 /usr/sbin/omv-engined(495): OMVRpc::exec('Config', 'applyChangesBg', Array, Array, 1) #11 {main}

Any help is appreciated.

Have you checked that the NFS share is not used anymore from external?

davidh2k · 23. September 2013

Yep Volker, at the time of the removal it wasn't used!

My Pi was offline when I tried to remove it. So no NFS share was used, because no other devices use the NFS shares.

Can you manually delete the directory (with the command executed by omv-engined) and check the error message.

Code

export LANG=C; rm -rf /export/pi 2>&1

Maybe you can do some more research why the directory is not deletable.

Code

root@chap:~# export LANG=C; rm -rf /export/pi 2>&1
rm: cannot remove `/export/pi': Device or resource busy
root@chap:~#

But, a reboot solved the problem... and now say linux doesn't require a reboot sometimes... apply config now works, besides a dozen communication failures while applying.

However, I can assure you that my Pi is the only thing that uses the nfs shares at all and it was powered down. So that can not be the root of the problem.
