In the spirit of all things open source I like to give new things a try. I mean why not? This isn’t Windows or OS X. I can reinstall easily, get my data back fairly easily, reinstall as many times as my hardware can stand, and try the newest edition of everything basically free.
So, when I recently reinstalled Gentoo on my desktop I tried out JFS. I’ve used ext2, ext3, ReiserFS, and even XFS. ext2 and ext3 are very stable but they’re not very quick. ReiserFS in my experience has been really good. But sometimes you get that, “i don’t want to use that, everyone else does” mood so you refuse. Finally, my stints with XFS have always ended in a crashed file system. Almost always do to a hard reset because of power failure. JFS on the other hand has survived its first obstacle. Depsite the power going out last night my computer rebooted this morning unscathed. Yes, it had to go through the whole replaying journal bit, but after that everything seems fine.
Enjoy the Penguins!
