Hi all

 

I just went to stop my unraid array before shutting down, to add another hard drive.  The browser window just sat on the screen with the drives "unmounting" and after a few minutes I kept trying to refresh the page.  Now the screen is blank with "Wait..." in the top left hand corner, with the browser message of "Waiting for tower..."

 

All my shares are unaccessible, but the server is powered.  I've tried the discrete shut down procedure via the power button on the server, but this is unresponsive.  However, I'm able to log-in to the server via a telnet session. 

 

I've followed the instructions for getting the syslog but of course I can't access the flash drive share!  Any ideas?  Is there a command I can use in the telnet to force the server to shut down cleanly, so I can reboot?

 

Any help would be appreciated

 

Thanks

it looks like something is accessing the mounted drives, so it can't unmount... make sure, no app is running, which is on one of the array disks. also make sure, you have no telnet session open, where you are in one of the mounted disks.

How do I make sure nothing is running?  Is there a command I can type in the telnet session to kill all processes?

Why has this been moved to user customisations?  Isn't this a basic support issue with the server hanging? 

Ok, I ended up doing a hard reboot, and the array is back online with no issues.  There's a couple of lines of red in the syslog, in two places:

 

Nov 10 15:57:02 Tower kernel: [787]: scst: __scst_register_target_template:253:***ERROR***: Target driver mvst_scst already registered

Nov 10 15:57:02 Tower kernel: [787]: scst: __scst_register_target_template:293:***ERROR***: Failed to register target template mvst_scst

 

And:

 

Nov 10 15:57:02 Tower kernel: atiixp 0000:00:14.1: simplex device: DMA disabled

Nov 10 15:57:02 Tower kernel: ide1: DMA disabled

 

Anyone know what these mean?

No, it is usually one of your add-ons that is keeping a disk busy and prevents the server from un-mounting a disk and the server stopping properly.  There are a number of add-ons that have this problem and must be first stopped before stopping the array.   

 

That is why I moved your post.  To a sub-forum where you could better get guidance and assistance.     

 

The error messages mean you have two of the same disk controller card on your server and the first one already registered the drive. (so the second attempt gets the advisory message)

 

ide1 is probably a device that does not support DMA (your flash drive perhaps)

You've not attached the syslog... So we cannot give a definitive answer.
