I recently discovered an interesting “feature” of symbolic links in conjunction with NFS mounts: they don’t work!<\/p>\n
For example, let’s say you have the following NFS export:<\/p>\n
\/media\/files<\/code><\/p><\/blockquote>\nInside of that export, you have the following path:<\/p>\n
\/media\/files\/isos\/osmedia\/linux\/ubuntu<\/code><\/p><\/blockquote>\nIn *this* directory, you have a symlink called ‘
current<\/code>‘, which points to a different location:<\/p>\n
current -> \/media\/osmedia\/linux\/ubuntu\/11.10<\/code><\/p><\/blockquote>\nHere’s the rub: if anyone tries to mount the root (or sub path) of that NFS export (say
\/media\/files\/isos\/osmedia<\/code>) at a local point (say,\/mnt\/osmedia<\/code>), the symlink will fail to work correctly<\/strong><\/em>\u00a0because there is no path\/media\/osmedia\/linux\/ubuntu\/11.10<\/code> on the local machine!<\/p>\nThat’s not cool.<\/p>\n
Here is another case where bind mounts<\/a> will save your bacon!<\/p>\n
Instead of using symlinks on the NFS host, use bind mounts – that way the path will still work<\/em>\u00a0when exported.<\/p>\n","protected":false},"excerpt":{"rendered":"
