Hi,
my nfsserver resource is configured like that:
primitive nfs ocf:heartbeat:nfsserver \
params nfs_shared_infodir="/server/nfs_infodir"
With older kernels, the bind mount produced by ocf:heartbeat:nfsserver
and the mount of the base filesystem looked like that in /etc/mtab:
/dev/mapper/server on /server type ext4
(rw,relatime,user_xattr,acl,barrier=1,data=ordered)
/server/nfs_infodir on /var/lib/nfs type none ...
and the is_bound function in ocf:heartbeat:nfsserver worked fine.
But with newer kernels (now I use Opensuse 12.1, kernel 3.1.9) the
mounts look like that:
/dev/mapper/server on /server type ext4
(rw,relatime,user_xattr,acl,barrier=1,data=ordered)
/dev/mapper/server on /var/lib/nfs type ext4
(rw,relatime,user_xattr,acl,barrier=1,data=ordered)
and the is_bound function cannot identify it's mount.
More information can be found in /proc/self/mountinfo:
/ /server rw,relatime - ext4 /dev/mapper/server
rw,user_xattr,acl,barrier=1,data=ordered
/nfs_infodir /var/lib/nfs rw,relatime - ext4 /dev/mapper/server
rw,user_xattr,acl,barrier=1,data=ordered
Here, it is visible that only the subdirectory nfs_infodir is mounted on
/var/lib/nfs.
Perhaps, that information should be used in is_bound.
Regards,
Eberhard
