Anyone using btrfs in production?
I hated lvm/lvm2 with a passion, and really enjoying how btrfs makes things easy for you.

How could you possibly hate lvm?

@Kimmax
Don't have a real objective reason, it just always felt awkward, even if it did the job right. Btrfs is not as elegant as zfs, but it surprisingly easy to understand and work with. Just not sure it's ready enough.

Currently on my server just experimentally (not using many subvolumes, no raid, no compression), but have been using it for years on desktop, notebook, cellphone and router with various features ensbled without any big issue.

@misiman
Cool, thanks, testing it in a backup server, compression feels a little sluggish sometimes,
plan to use snapshot and deduplication, replacing hardlink rsyncs.

btrfs ate two ssds on me because I didn't realize I had to configure trim outside of fstab Dx

@squirvel
Ouch

@nbamaral Never had issue with compression, but I'm using lzo and benchmarks claim that it made my harddrive even faster. For databases and other IO intensive applications it is recommended to turn it off and turn of cow as well.

@misiman
Yes, testing with lzo as well, this was just an impression, but it made sense since this server task is rsync data from the rest.
Read compression can be nasty for kvm storage too. And probably cow too if using cow2.
Thanks for the feedback 😊

@Zennoe
Thanks. I am way to conservative to move the root filesystem to btrfs just yet. But the atomic snapshot are very interesting indeed.
I'm taking baby steps here, I'll get into snapshots next week, in parallel with what I already have.
