What about inode file system? (Re: the current status of nullfs, unionfs)

2005-03-11 Thread Mikhail Teterin
A few years ago, there was a project making a filesystem, where a file's name will simply be its inode number. It was intended to save on the name-to-inode lookups of a regular filesystem, for applications like Squid, which keep file names in some sort of a database already. Does anyone know,

Nullfs works better than unionfs. Unionfs worked well in 4.X. What about the `union' option to regular mounts? Is that safe to use? [...] Last I checked, it [mount -ounion -mi] was very broken, but I'm not sure. BTW, how is unionfs different from nullfs with the union option? mount

Hi David, Nullfs works better than unionfs. Unionfs worked well in 4.X. Despite numerous minor bugs such as being unable to cope with FIFOs, several people have reported using it quite successfully on production systems. However, unionfs no longer works quite as well in 5.X or -CURRENT.

That obviously depend on your use of jails and nullfs. It works just fine for me. For me too. I mount /bin /sbin /lib /usr/bin /usr/sbin /usr/lib /usr/libexec /usr/libdata /usr/share in all my jails using nullfs, thus I avoid wasting storage space and an upgrade of the host also automatically

Hello! The respected manual contain dire warnings, but the Google search suggests, the situation is not *that* gloomy. For example, according to http://kerneltrap.org/node/652 , nullfs was used on Bento-cluster two years ago in 2003. Is anybody working on this file-systems? Any plans,

At the risk of bringing up the L word on this forum :-), we have a fan-out unionfs implementation for Linux that doesn't explode very easily. See http://www.filesystems.org/project-unionfs.html Cheers, Erez. ___ freebsd-hackers@freebsd.org mailing list
