RedHat EL 4.0 and Journaling File Systems
On Thu, 26 Jan 2006 01:18:11 -0800, Aldrin Fabricius OK, let's start with the basics...
One of the differences between RedHat Enterprise Linux and Fedora Core is the fact that Fedora seems to include support for several different journaling file system types, while EL seems to ONLY support ext3. In EL 3.0, you could find the drivers and tools for JFS, Reiser and a few others under the "unsupported" modules, but come 4.0, even those seem to have disappeared.
hi; unfortunately, i can't read chinese, but from here; familiar win98 look of the distro) and possible links to forums and other info. That said - being it's a knoppix based distro - and i've used and...
I am running EL at work, mostly because it's the best corporate "supported" version, however I have a couple of servers which have mbuttive disk arrays (SAN) that are approaching the 2TB size. Unfortunately, while ext3 is an excellent all round journaling file system, it still has a hard upper limit of 2TB on any one parbreastion (since it's based on ext2 and the FFS i-node design). In addition, from the tests I've been able to do, the performance starts dropping off pretty badly when you get that big.
My question is, does anyone know what plans Red Hat has for supporting any of the modern journaling file systems out there (JFS, XFS, ReiserFS, etc.)? I know they have their own "GFS" for sharing large file systems between servers (kind of like NFS on steroids), but that's not really what I'm looking for. I'd even be willing to pay for licensing some sort of pay-for extension, if it was in reason.
