File system UFS2 gjournal support
FreeBSD 7.0 will be the first FreeBSD release with gjournal support when this feautures will be available on OpenBSD and NetBSD? I think is a great features. |

When probably be a case of when == 'it is ported, if desired' occurs.
I for one, am happy with soft updates lol. (good thing I'm not the ones that would have to implement it on OpenBSD and NetBSD :-P)

Thanks, your answer is very precise.
![]() But if skipping the light (assuming that there isn't a Ups) and the partitions are large requires a long fsck of hdd don't think that it may be a weak point for an operating system especially when typically are used in server? Or the problem does not arise because since the servers are equipped with ups there relies entirely hardware? I have another question correlated with the previous whereas I understand is unlikely to support a journalized in openbsd and netbsd. When will change the license file system ZFS (on Gpl) is a concrete hope to be adopted as default by all systems Bsd? |

OpenBSD will certainly not use a journal, because it's not secure. But NetBSD has got a journaling filesystem of its own, a real one.

Why do you say that file system journalized it's not secure?
I thought it was the opposite. Which is the main difference between the two solutions (freebsd and netbsd)? This article says that the solution netbsd has been tested for several years and enormous amounts of data. Why it could not be used, for example, on the systems openbsd?

Secure as in privacy. >Which is the main difference between the two solutions (freebsd and netbsd)? http://mail-index.netbsd.org/tech-ke...msg000504.html or in detail: http://www.wasabisystems.com/technology/wjfs and last not least gjournal: http://www.freebsd.org/doc/en/books/...-gjournal.html and http://lists.freebsd.org/pipermail/f...ne/064043.html If you're interested in the differences between journaling and soft updates, http://www.usenix.org/publications/l...l/seltzer.html

Many thanks!!!
Talking about the security you could encrypt the data, even if this would have some impact on the overall performance of the system. 19.7 UFS Journaling Through GEOM: "Unlike other file system journaling implementations, the gjournal method is block based and not implemented as part of the file system - only as a GEOM extension." Now i understand the importance of a file system journaling based on GEOM extension. Last edited by aleunix; 30th May 2008 at 06:52 AM. |
