The 1999 FreeBSDCon event (October 17-23rd) is filling up fast, so please register soon if you want to attend this event! Due to overwhelming demand for Kirk McKusick's BSD Internals tutorial (which sold out several weeks ago), we have also just made arrangements for a "repeat performance" on the 22nd and 23rd of October. People already on the waiting list for the October 17th and 18th sessions will have first option for the second session (upon c...

Hello, I've got performance problems with copying small files over to a Samba share in a directory that has lots of small files (10000 to 20000 files). It takes too long time to copy new files (they drip in at a fast pace), and smbd eats a lot of CPU time. Is there any way to make Samba run faster in this situation? Cheers, -- Anders Nordby Aftenposten AS, Systemteknisk avd. Tlf.: +47

There is a confusion about the name of this file system, then I decided to contact the author (Kirk McKusick) who replied: "The name has always been confusing (my bad). The code is broken into two parts, the part that handles naming (UFS where the U stands for Unix), and the part that handles disk layout (FFS where the F stands for Fast). When the two parts are put together they are called UFS/FFS or...

I just burned 3 hours figuring out Subversion, so I made up a little quickstart guide. Try the guide and see if you can get version control going in ... say ... 30 minutes? I assume your situation is: You are setting up version control on a new subdirectory on your computer. You will copy your entire rails project directory tree into the new subdirectory after you get subversion running.

...tem integration and rapid technology transfer. The project will be lead by NAI Labs Research Scientist Robert Watson, and NAI Labs Chief Scientist Lee Badger. The work will be done in part by sub-contractors from the FreeBSD development community, including Kirk McKusick, Poul-Henning Kamp, Jonathan Lemon, and Eivind Eklund. The $1.2 million will be paid over the life of an 18-month contract. Today's evolving military and business processes increasingly rely...

In the old days NFS Shared Path had a static handle (ie a number), normal based on some number pulled out of the file system/inode. To fix (well work around) a security issue, for about 10+ years now, when a NFS server reboots, it generates a new random handle for the NFS Share. (sever may generate a new random handle per mount request) The NFS Stale Handle happens when the client is still

Ok, so I ran fsck manually (even with -y), but yet it refuses to clear/fix whatever to the questions posed as fsck runs. What does this all mean? Thanks, -Clint -- This message has been scanned for viruses and dangerous content by MailScanner,

Here's a patch against 4.8-RELEASE kernel that allows disk writes on softupdates-enabled filesystems to be delayed for (theoretically) arbitrarily long periods of time. The motivation for such updating policy is surprisingly not purely suicidal - it can allow disks on laptops to spin down immediately after I/O operations and stay idle for longer periods of time, thus saving considerable amount

"Does raidzN actually protect against bitrot?" That''s a kind of radical, possibly offensive, question formula that I have lately. Reading up on theory of RAID5, I grasped the idea of the write hole (where one of the sectors of the stripe, such as the parity data, doesn''t get written - leading to invalid data upon read). In general, I think the same applies to bitrot of
