Description Robert de Bock 2010-07-28 07:54:33 UTC

Description of problem:
If an ISO image is listed in /etc/fstab, the startup procedure tries to mount it twice during boot.


Version-Release number of selected component (if applicable):
Fedora Core 13

How reproducible:
Add this to your /etc/fstab and reboot:
/var/www/html/Fedora-13-x86_64-DVD.iso /var/www/html/kickstart/fedora/13/x86_64 iso9660 loop,ro 0 0

Steps to Reproduce:
1. Download an ISO, put it on your harddrive.
2. Edit fstab to mount that downloaded ISO.
3. Reboot.
  
Actual results:
During boot, you will see the ISO's being mounted twice:
...
Checking filesystems
Fedora-13-x86_64: clean, 128566/3678208 files, 6525382/14704640 blocks
...
Mounting other filesystems:  mount: according to mtab /var/www/html/Fedora-13-x86_64-DVD.iso is already mounted on /var/www/html/kickstart/fedora/13/x86_64 as loop
...

Expected results:
No errors during boot up.

Additional info:
Here are other users having a similar issue on FC 12: http://lists.fedoraproject.org/pipermail/users/2009-December/095116.html

I think the error can be pinpointed here:
In /etc/rc.sysinit, there is a line:
mount -a -t nonfs,nfs4,smbfs,ncpfs,cifs,gfs,gfs2 -O no_netdev
In /etc/init.d/netfs, there is a line:
action $"Mounting other filesystems: " mount -a -t nonfs,nfs4,cifs,ncpfs,gfs

Both lines when ran manually after a boot display this error:
mount: according to mtab /var/www/html/Fedora-13-x86_64-DVD.iso is already mounted on /var/www/html/kickstart/fedora/13/x86_64 as loop

Looks like it's possibly an accounting error in util-linux/mount.

Comment 2 Karel Zak 2010-07-29 14:44:19 UTC

This is side-effect of auto-clear loop devices. Fixed in upstream repository, the bugfix will be available in Fedora ASAP.
