A Beginner's Guide To btrfs 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.

Do you run ispconfig on top of btrfs?

Atm, I'm trying to convert my /var partion of my webserver managed with ispconfig to btrfs. I expect issues with the quotas...

[...] /dev/sdb /mnt btrfs defaults,compress=lzo 0 1 [...]

This is no longer the case in Ubuntu 16.10

 

# /etc/fstab: static file system information.

#

# Use 'blkid' to print the universally unique identifier for a

# device; this may be used with UUID= as a more robust way to name devices

# that works even if disks are added and removed. See fstab(5).

Can you add onto this guide, how to add cache to a BTRFS array?

Or build one with cache?

If you are replacing a failed hard drive, and the new drive is equal or larger in size, always use btrfs replace instead of device add and remove.

Replace is roughly 20-40x faster.  Add/remove will rewrite more or less the whole filesystem--slowly.
