Jeff Roberson добавил журналирование к UFS

Вот это новость!
Джефри Робсон (Jeff Roberson), автор планировшика ULE и один из ключевых разработчиков FreeBSD, произвел улучшения в работе механизма Soft Updates файловой системы UFS. Им был добавлен механизм журналирования метаданных изменяемых при работе Soft Updates. Данное нововведение позволит отказаться от необходимости запуска fsck после "грязного" размонтирования файловой системы. Новая система журналирования позволяет достичь очень высокой скорости востановления состояния файловой системы при очень малом объеме журнала.
Данная работа была выполнена по заказу компаний iXsystems, Yahoo!, и Juniper networks. В ближайшее время код будет доступен пользователям ветки FreeBSD 9.0-CURRENT.

Journaling softupdates, SU+J
I suspect that most people who read this blog are familiar with journaling as a mechanism for ensuring post-crash filesystem consistency. Some of you may also be familiar with copy-on-write and log structured filesystems as an alternative to journaling. BSD's ffs, an extension of the original unix filesystem, has used an alternate approach called soft-updates to handle filesystem consistency for around 10 years. For the past few months, I have been creating a hybrid journaled softupdate system to deal with inadequacies in the existing softdep system. This work is opensource and will be available to FreeBSD-current users sometime this month. Behind the cut I briefly describe the tradeoffs in each consistency mechanism and motivation for this work.
If filesystem technologies are the subject of fads, it seems everything in the human experience must be. Lately we've seen an resurgence of copy-on-write (COW) filesystems which have been popularized seemingly by ZFS but have existed at least as far back as 1990's Rosenblum paper on LFS. These may be particularly attractive on flash media where seek time is not a problem and where clustering writes together can improve erase block fragmentation issues. However, on spinning media COW tends to fragment the drive and reduce the quality of allocation decisions by enforcing essentially at least two versions of any modified data to be reachable at once.
Journaled filesystems were of course the earlier fad. In this mechanism a copy of any metadata and sometimes data that is to be modified is kept in a journal, a fixed area of the disk or another disk, that logs each modification. In this mechanism the journal is replayed on reboot and the filesystem is left in a consistent state. The problem with journaling is either it's very simple and uses a tremendous amount of space and I/O with a strict transaction model that prevents some concurrency, or it becomes incredibly complex, to the tune of over 20,000 lines of code in xfs. Still I have questions about concurrency when multiple transactions affect a block in xfs, but I need to dig deeper to understand this.
Soft-updates is an alternative to this scheme where the filesystem keeps a list of dependencies that must be satisfied before a change to the filesystem can be visible on disk. For example, you wouldn't want to write a directory entry pointing at an inode until the inode was initialized on disk and marked allocated. Softdep handles this by rolling back changes to metadata that don't yet have their dependencies satisfied when we try to write a block. In this way we can commit any completed 'transactions' while keeping the disk state consistent. Softdep also allows these dependencies to discover operations which cancel each other out and thus nothing makes it to disk. For example, let's say you create a temporary file and then remove it after writing some blocks, which compilers often do, if it all happens within the interval of the syncer nothing will make it to disk.
Soft-updates guarantees that the only filesystem inconsistencies on unclean shutdown are leaked blocks and inodes. To resolve this you can run a background fsck or you can ignore it until you start to run out of space. We also could've written a mark and sweep garbage collector but never did. Ultimately, the bgfsck is too expensive and people did not like the uncertainty of not having run fsck. To resolve these issues, I have added a small journal to softupdates. However, I only have to journal block allocation and free, and inode link count changes since softdep guarantees the rest. My journal records are each only 32bytes which is incredibly compact compared to any other journaling solution. We still get the great concurrency and ability to ignore writes which have been canceled by new operations. But now we have recovery time that is around 2 seconds per megabyte of journal in-use. That's 32,768 blocks allocated, files created, links added, etc. per megabyte of journal.
This work is being funded by a group of companies, iXsystems, Yahoo!, and Juniper networks. I'm interested to see if this kind of project if feasible in the future where companies can share development costs for specific opensource projects.
The work is being done in collaboration with Kirk McKusick, the original author of ffs and softupdates. We will likely present a paper at BSDCan and then at a more formal venue following that. The code will be publicly available within two weeks.

Чуть попереводил. на опеннет тоже закинул.
Это же рулез! UFS is back! Тормоза при fsck очень напрягают, а тут появится резон использовать ее на больших разделах где иначе нет альтернативы ZFS (если специально не нужны ее фишки какие-нить)!

Чем отлично то? Кто-то мне недавно доказывал, что журнал не нужен!

пока zfs работает не искаропки и требует много памяти - он далеко не везде будет использоваться

Счас еще одну штуку попробую, если не получится - отпишусь.
У меня исходники от карента, но система еще 8.0-релиз
Я решил одним махом накатить ее до карента и сразу же в процессе поставить патчи. Может поэтому не собирается, что родительская еще как бы не очень карент.
Сча сделаю карент по честному и попробую уже на нем...

Hi Folks,
You may have seen my other Soft-updates journaling (SUJ) announcements.
If not, it is a journaling system that works cooperatively with
soft-updates to eliminate the full background filesystem check after an
unclean shutdown. SUJ may be enabled with tunefs -j enable and disabled
with tunefs -j disable on an unmounted filesystem. It is backwards
compatible with soft-updates with no journal.
I'm going to do another round of tests and buildworld this afternoon to
verify the diff and then I'm committing to head. This is a very large
feature and fundamentally changes softupdates. Although it has been
extensively tested by many there may be unforseen problems. If you run
into an issue that you think may be suj please email me directly as well
as posting on current as I sometimes miss list email and this will ensure
the quickest response.
Thanks,
Jeff
SUJ теперь в CURRENT
