A Beginner's Guide To btrfs


Hi,

A Beginner's Guide To btrfs
Quote:
This guide shows how to work with the btrfs file system on Linux. It covers creating and mounting btrfs file systems, resizing btrfs file systems online, adding and removing devices, changing RAID levels, creating subvolumes and snapshots, using compression and other things. btrfs is still marked as experimental, but all those features make it a very interesting and flexible file system that should be taken into consideration when you look for the right file system.
I do not issue any guarantee that this will work for you!

Interesting! Wikipedia has quite a good page, too, and there's also https://btrfs.wiki.kernel.org/index.php/FAQ

The last time I checked, fsck had no btrfs module: it was said to be "imminent" a year ago. There is btrfsck, but it comes with the warning "may cause additional damage". As for me, I'm still using ext3.

This might also be useful in this thread, some btrfs benchmarks:
http://openbenchmarking.org/result/1...BY-BTRFSBUNT08
Honestly, they aren't much in favor of btrfs, and with the experimental fsck, you may want to think twice before switching. As can be seen in the benchmark, with recent kernels XFS and JFS have improved significantly, and btrfs has lagged behind.

Very interesting.
Thank you

Note that the benchmarks are done on a SDD not a HDD, I forgot to mention that, but my internet went out.

For speed, it seems you can't beat XFS. That's why the BBC has been converting its editing computers to Linux. On the old Windows system, they filmed with the cameras recording onto magnetic tape, and then the next day was taken up by someone uploading the tapes. With XFS, they can have half a dozen HD cameras dumping their output straight onto the computer.

Is BTRFS an experimental filesystem or is it stable?

Btrfs is under heavy development, but every effort is being made to keep the filesystem stable and fast. Because of the speed of development, you should run the latest kernel you can (either the latest release kernel from kernel.org, or the latest -rc kernel. Please email the Btrfs mailing list if you have any problems or questions while using Btrfs.

Thanks onebuck for the info. But I will wait awhile before using btrfs on my main production machine.
