Bug 508574 – sys-apps/openrc-0.12.4: netmount doesn't netmount

• Product: Gentoo Hosted Projects
• Status: RESOLVED FIXED

[Description Patrick Lauer 2014-04-24 05:37:51 UTC]

In fstab:

192.168.0.8:/usr/portage                /usr/portage    nfs             defaults        0 0
192.168.0.8:/usr/portage/distfiles      /usr/portage/distfiles    nfs             defaults        0 0


localhost ~ # /etc/init.d/netmount restart
 * Unmounting network filesystems ...           [ ok ]
 * Mounting network filesystems ...             [ ok ]

localhost ~ # mount | grep nfs
rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
nfsd on /proc/fs/nfsd type nfsd (rw,nodev,noexec,nosuid)

localhost ~ # mount -a
rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
nfsd on /proc/fs/nfsd type nfsd (rw,nodev,noexec,nosuid)
192.168.0.8:/usr/portage on /usr/portage type nfs (rw,addr=192.168.0.8)
192.168.0.8:/usr/portage/distfiles on /usr/portage/distfiles type nfs (rw,addr=192.168.0.8)

So that's a bit of a downer ...

+ ebegin 'Mounting network filesystems'
 * Mounting network filesystems ...
+ mount -at afs,ceph,cifs,coda,davfs,fuse,fuse.sshfs,gfs,glusterfs,lustre,ncpfs,ocfs2,shfs,smbfs

so, nfs is not in the explicit list of network FS, and mount -a -O _netdev doesn't find it. mount -a does mount it.

[Comment 2 Patrick Lauer 2014-05-06 05:41:25 UTC]

        for x in $net_fs_list $extra_net_fs_list; do
                case "$x" in
                        nfs|nfs4)
                        continue
                        ;;
                esac
                fs="$fs${fs:+,}$x"
        done


... the init script goes out of its way to prune nfs from the list of network FS ? Eh what? :D

[Comment 3 Patrick Lauer 2014-05-06 05:44:17 UTC]

So, it might work if I changed fstab options from "defaults" to "defaults,_netdev" - but why would I do that? 

"""
       _netdev
              The filesystem resides on a device that requires network access (used to prevent the system from attempting to mount these filesystems until the network has been enabled on the system).
"""
(from the manpage)

And why do we have an independent nfsmount init script?

[Comment 4 William Hubbs 2014-07-09 18:26:22 UTC]

Created attachment 380504 [details, diff]
netmount.patch

Eventually, I would like to take this route. On Linux, we don't need an
explicit network fs type list, because we should rely on -O _netdev.

Try this patch and make sure the nfs services are started before netmount.
Let me know what that does.

This might be controversial since it relies on -O _netdev which
busybox's mount command doesn't support.

[Comment 5 Rick Farina (Zero_Chaos) 2014-10-01 16:02:56 UTC]

netmount init script doesn't handle nfs, nfsmount init script does.  This has been this way for some time now... The proposed patch will certainly cause issues.

[Comment 6 William Hubbs 2014-10-18 19:01:06 UTC]

A fix for this has been implemented in commit 85da4a5 which will be
included in OpenRC-0.14.

This bug was caused by an incorrect fix for bug #427996.
The code that started the daemons should have been removed, but not the
code that mounted the nfs file systems.
