Hmmm ... the problem is: I'm not able to reproduce and this is the requirement to debug and fix this.

Do have also an strace *which* works, please specify the options

-s 1024 -f

to strace so I'm able to read the full strings used for open and read the files.

Also a strace output of a fuser which does *not* work for comparision would be perfect (clearly with the same options).

Can do and will do, however to get fuser to work I'd probably need to reboot the machine, after which it works again for unknown duration. So I could not provide you with other info after the boot. So, before I do the reboot, is there any other info in the non-working situation besides a fuser strace that could be helpful, as afterward it might take a while before it fails again. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Hmm ... just a few questions about your setup: I'd like to know which system is used for domain 0 of your VMware setup. Also I'd like to know which kernel's are used for domain 0 and the client hosted on. Then the network setup of both the domain 0 and the client would be perfect.

The at-the-moment-problematic-machine runs under VMware VSphere 4.0. The first time I noticed this problem though, was on a openSUSE 11.3 host with 2.6.34.8-0.2-default kernel running VMWare server Version 2.0.2. I have not seen the problem again on the 11.3 host though, but it got updated to RC2 in the meantime so comparison may be invalid. What would you want to have as the network setup, something from /etc/sysconfig? I'll reboot the problematic machine shortly and supply the strace of a (hopefully) successful fuser. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

... then this is more a VMware specific bug, isn't it? network setup means: are there any bridges or some other uncommon devices around on domain 0 and/or client?

The client has no bridges or whatever, just a static ip at eth0, default gw etc. The 11.3 client eth0 device is bridged to a 11.3 network interface, never gave me any problems. For VMWare VSphere I don't know at the moment, as I don't have console access to it. I have made various VM's using openSUSE 11.1 to 12.1, Redhat ES 3, 4, 5 etc. Only openSUSE 12.1 shows the (sometimes) failing fuser symptoms, so as fas as can see it is not related to VMWare. But, as I don't have a spare hardware box around to install 12.1 on, I can't rule it out either. In the meantime, I've rebooted the vm, and now fuser works again. I'll attach the strace previously asked in the hope this may shed some light... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Please test out both binaries of attachment #460937 [details] and attachment #460939 [details] but be aware that those binries work different.

I'd like to know how both do their works that is if one or both will fail the same way on your virtual system as the original one.

Will do, the moment it fails again. Since reboot day before yesterday it's still working OK. There is perhaps one relevant change: I've now rebooted with sysvinit, while previously it was systemd. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Then I'd like to know *why* root is not allowd to do a stat(2) system call on this .gvfs file?

It seems normal behaviour, just google around. I also get these kind of access errors while making a backup as root, on all kinds of machines with this .gvfs present.
