Re: getting "device busy" on smbfs mounted area
You could try umount -l /p2dev (lazy unmount) Scott On Fri, Mar 20, 2009 at 10:17 AM, Mark D Vandale wrote: > In our fstab we mount a smbfs filesystem on z/OS..

getting "device busy" on smbfs mounted area
In our fstab we mount a smbfs filesystem on z/OS.. It works for a while but at some point we are getting hung up. I have no idea what's causing this. Executing any cmd against it hangs for a while and the returns this device busy message. Is there a way to get around this or force it to be unmounted ? zlnx1a04:~ # umount /p2dev umount: /p2dev: device is busy Thanks, Mark Vandale -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: Device busy
Werner, This has been experienced previously. If you're "adding" a new control unit to an LPAR, you have to manually configure it online to the LPAR before it can be used. For MVS, etc., this can be done by the operating system, but you'll probably need to do it from the service console.

Re: Device busy
No, just one CEC. I also believe that a POR would do the job, but I fear I won't get the time for a POR :-( I'd like to know if this is a consequence of dynamically changing the access to the devices and OS/390 2.10 or JES3 doesn't really give them free, although they're offline.

Re: Device busy
Werner, I got something like that on an OS/390 IPL attempt. The same message, and the devices in question were "off line" to all other LPARs. I then did a "reset clear" on the LPAR that I was attempting to IPL, then IPL'ed it again. This time it worked! It appears that the microcode assumed that the IPL was still being attempted, even after the error message was displayed. The "RESET CLEAR" cleared up the problem. -- John McKown Senior Technical Specialist UICI Insurance Center Applications & Solutions Team +1.817.255.3225 -Original Message- From: Werner Kuehnel [mailto:werner.kuehnel@;mannheimer.de] Sent: Monday, November 11, 2002 5:05 AM To: [EMAIL PROTECTED] Subject: Device busy I installed Linux (SLES for S/390) onto 3 3390-3 volumes some months ago and got it started from disk.
