when trying to open a file
So after quite a bit of debugging I have found out that apparently the problem is that my NFS server has a share that's not available for my IP address (only for another one) and fhStatus.fhs_status (in nfsv3.cpp->openConnection()) gets set to 13 and if checks if the status is zero and otherwise throws an error (not right away but later). I have managed to work around this problem by putting a
else if(fhStatus.fhs_status == 13) {
continue; // skip mounts with no permission
}
there and I can now browse my NFS share again.
luca@g550jk ~> showmount -e 192.168.0.50
Export list for 192.168.0.50:
/mnt/data/libvirt 192.168.0.21
/mnt/data/media (everyone)
Sample patch that *works around the problem* is attached. Note, that I have little experience in NFS and have no idea what the "13" actually means.

Workaround patch, not a proposed patch!
The NFS ioslave has been updated to handle mount permissions problems and report the error correctly when a file needs to be accessed. It will also ignore mounts which cannot be accessed and still allow access to those that can. Please test with a current build if possible, and reopen if there is still a problem. |
