[SOLVED] dolphin does not show files/folders after upgrade

[magfan]

Upgrading from Mageia 1 to Mageia 2 went smoothly. Yes, but...

When I start dolphin it does not show anything like files or folders. Just an empty space. I added _netdev for my NFS mounts in fstab, but this did not change anything. Any ideas?

[djennings]

Are you saying that Dolphin starts with a blank page, but you can navigate to folders, or are you saying dolphin is blank no matter what you do?

When I start dolphin it does not show anything like files or folders. Just an empty space. I added _netdev for my NFS mounts in fstab, but this did not change anything.

The _netdev thing was for a totally different issue. And are you talking about accessing your NFS mounts, or where exactly does dolphin show nothing?
Does the problem also persist when trying with a freshly created user?

[magfan]

The only time dolphin shows something is when I right-click on the desktop an select "open with dolphin". Only in this single case dolphin shows the icons from the desktop. But I cannot navigate to different folders. That is why I thought this behavior has something to do with the file systems and I mounted two NFS directories with this additional option. But it did not help. In the meantime I discovered that also the file open dialog of kwrite (or any other KDE program) does not let me navigate and does not show anything.

Is konqueror installed?

[magfan]

Yes, konqueror is installed and has the same problem.

I just called kdf and realized that the same NFS directories (/data1, /data2) seem to be mounted twice: once unsuccessful (NFS) and once successful (NFS4). Maybe that causes problems? Anyway, I do not know how to set it to only one NFS version.

Another thing is that all partitions appear as "removable devices".

Please show the output of

Code: Select all

showmount -e

and also the contents of /etc/exports from the NFS server and the contents of /etc/fstab from the client you're having this problem with.

Can this be related to the following bug?

https://bugs.archlinux.org/task/27851

[magfan]

I could solve the problem be editing /etc/fstab (adding a slash at the end of the mounted directory). Instead of just "/data1" and "/data2" I had to mount "/data1/" and "/data2/" like in /etc/mtab:

Code: Select all

cat /etc/fstab | grep amygdala_nfs
amygdala_nfs:/data1/ /data1 nfs rsize=8192,wsize=8192,nosuid,soft 0 0
amygdala_nfs:/data2/ /data2 nfs rsize=8192,wsize=8192,nosuid,soft 0 0

cat /etc/mtab | grep amygdala_nfs
amygdala_nfs:/data1/ /data1 nfs4 rw,nosuid,relatime,vers=4,rsize=8192,wsize=8192,namlen=255,soft,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.4.1,minorversion=0,local_lock=none,addr=192.168.4.2 0 0
amygdala_nfs:/data2/ /data2 nfs4 rw,nosuid,relatime,vers=4,rsize=8192,wsize=8192,namlen=255,soft,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.4.1,minorversion=0,local_lock=none,addr=192.168.4.2 0 0


Could the missing slash be automatically added by mcc? That would be nice.

[doktor5000]

How did you setup those NFS mounts on the client?

And yes, it could be related to the bug you mentioned, but i'm not sure.

[magfan]

How did you setup those NFS mounts on the client?

I used mcc to create /etc/fstab. Later I added the trailing slashes manually when I saw that the system itself uses them in /etc/mtab. Unmounting and mounting again solved the problem.

[magfan]

I thought the problem was solved, but it is not! Dolphin works very well as long as you never try to access a NFS mounted directory via dolphin. It turns out to be very closely related to bug https://bugs.archlinux.org/task/27851. Is there any chance to "downgrade" the filesystem package?

[djennings]

Dolphin works very well as long as you never try to access a NFS mounted directory via dolphin.

I do not have the same problem with Dolphin and NFS mounts.
You never answered when asked if a new user has the same problem?

Can you navigate the NFS file system using Midnight Commander ( mc ) on the command line? (as your user)

[magfan]

Yes, any user on this system. I deleted my own account including $HOME and created a new account again. But it did not help. Doing so I could solve another problem (viewtopic.php?f=7&t=2632) but the NFS problem remains.

There is no problem to navigate the NFS file system using konsole or mc.

[djennings]

Just as an experiment.
What do you get if you put the URL into Dolphin or Konqueror

Code: Select all

nfs://amygdala_nfs:/data2

An error like "authentication failed. amygdala_nfs not supported"

[htgoebel]

I'm experiencing the same problems. Not only in dolphin, but also on the Desktop, see https://forums.mageia.org/de/viewtopic.php?f=8&t=724.

My /home is mounted via NFS, too.
