I'm running the following configuration with davfs2 package from repoforge:
CentOS release 5.9 neon-0.25.5-10.el5_4.1 davfs2-1.4.6-1.el5.rf
I'm testing davfs2 by connecting from a Centos server to dav.box.com. It works
fine as long as the server dav.box.com is accessible on the internet.
I asked my self what will happen if dav.box.com is not responding or if it's
responding but the remote share doesn't exist. I went ahead
and mapped dav.box.com on my /etc/hosts file to a non accessible IP address
and this is what happened:
a. When I try mounting using the following command line:
mount -t davfs dav.box.com/dav /mnt/box.com
b. The server creates the following process:
[Centos]# ps -ef | grep mount davfs2
17925 1 0 15:16 pts/0 00:00:00 /sbin/mount.davfs dav.box.com/dav /mnt/box_com
-o rw
c. This process stays there indefinitely creating the following messages:
[Centos]# /sbin/mount.davfs: connection timed out two times; trying one last
time [Centos]# /sbin/mount.davfs: connection timed out two times; trying one
last time /sbin/mount.davfs: server temporarily unreachable; mounting anyway
d. After 3 times trying, the "df -h" will hang for few minutes until it shows
the mount point: https://dav.box.com/dav 26G 13G 13G 50% /mnt/box.com
It shows the mount point which is not accessible.
e. The davfs2 process stays alive:
[Centos]# ps -ef | grep mount davfs2 17925 1 0 15:16 pts/0 00:00:00
/sbin/mount.davfs dav.box.com/dav /mnt/box.com -o rw
f. It creates the following entry under /proc/mount
https://dav.box.com/dav /mnt/box_com fuse
rw,nosuid,nodev,user_id=0,group_id=0,allow_other,max_read=16384 0
0
I checked all the davfs2 config options and nothing is letting me to
automatically umount if connection times out. The davfs2 version on Ubuntu has
a nomountanyway option which don't exist on the Centos davfs2.
How can I try in Centos 5.9 to mount dav.box.com/dav in a way that if it
doesn't mount properly because the connection is timing out or the share
doesn't exist, it will completely terminate any davfs2 process and do a umount
??
Thanks in advanced.
