Filed under: Friday Favorite R-Name is a simple, single-purpose application that takes the names of files and folders on your Mac and renames them one at a time or in batches. I use it almost every day. Yes, there are a dozen ways to batch rename files. I like R-Name for a few reasons: It's fast, bo...

This article was culled from Starting ZFS-FUSE up properly Here is a collection of tips you must pay attention to: Put the ZFS PID file in the root filesystem. Unset the LANG environment variable.  Failure to do so will cause ZFS-FUSE to hang if your /usr is on ZFS. Immunize ZFS-FUSE against th...

We, as file system and file system filter driver developers, are aware of the perils of issuing IO on the file system stack at APC level or with special kernel APCs disabled. Such IOs trigger unwanted side effects in the system that cause noticeable end user frustrations like hung IO completions and...

I often find myself looking at a programming language and wondering, “will this language be the one I use to implement my operating system which will change the universe?” Now, we both know I’m probably never going to do that, but I think it’s a useful thought experiment anyw...

Pimp My Drive by Richard and Barb There’s remarkably little information online about using MySQL on ZFS, successfully or not, so I did what any enterprising geek would do: Built a box, threw some data on it, and tossed it into production to see if it would sink or swim. I’m a Linux geek,...

"I regularly run and post various benchmarks comparing POHMELFS, NFS, XFS and Ext4, [the] main goal of POHMELFS at this stage is to be essentially as fast as [the] underlying local filesystem. And it is..." explained Evgeniy Polyakov, suggesting that the POHMELFS networking filesystem performs 10% t...

"After another round of performance tuning HAMMER all my benchmarks show HAMMER within 10% of UFS's performance, and it beats the shit out of UFS in certain tests such as file creation and random write performance," noted DragonFly BSD creator Matthew Dillon, providing an update on his new clusterin...

The second hard drive (hd1a) in my SCO 5.0.5 suddenly has the wrong name (d1257all) and all of it's mount points (/u1 /u2 & /u3) are gone. Like someone went in and removed everything from divvy. I have good backups and the primary hard drive is good, can I just re divvy and restore from backup o...

Modern Linux system uses UUID instead of traditional block name (/dev/hda1, /dev/hda5, /dev/sdb) to uniquely identify harddisk or other storage medium. This is because UUID is unique and never changes even if you switch the harddisk ordering. So by mounting or refering your hard disk by its UUID, yo...

Right, my external HD enclosure has finally arrived, and so I will be cloning my MacBook's hard drive and swapping them over, thus leaving me with a 60 GB external hard disk. However, I'm at a bit of a loss as to what file system to stick on it....
