And the system in question here will be a server running 24/7 with pretty intense load, so fast recovery IS an issue.. I haven't been running ext3 for several years, so I don't know how it performs really.. I guess for speed and disk intense use, XFS or JFS looks like good alternatives. My own experiences with XFS is that while it's running, it's fast although a bit cpu demanding. Recovery is painfully slow after a serious disk trashing, even slower than a rebuild-tree with ReiserFS v3.
Then I saw a note in OpenSUSE 11 that there are absolutely no support for JFS, but it seems like it's working anyway.. ;-)
Yeah, it's working very well ... :-) Purely anecdotal evidence - I have been using JFS on our production systems for the last four years, 24x365. All of external (rented) servers are JFS on RAID1-over-*ATA, our local systems are typically JFS on HP hardware RAID1 or -5. For the bigger filesystems, we add LVM to the mix. I think I have had two incidents where I needed JFS support - one was some years ago, and I can't really remember what it was about, but Dave Kleikamp was very responsive and helpful. Second time was the full filesystem check I mentioned earlier, and in this case there wasn't much anyone could do. It was a near-disaster, but I managed to salvage most of the data. My attitude wrt filesystems - if it needs active support, it's not sufficiently mature. A filesystem that is no longer in active development is mature. So asking for active support and development = asking for an immature filesystem. /Per -- /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
