| Sorry, but this is an anecdata. Down there, 2/3 of this hackersnews discussion (if you are patient to get there) you can see questions about production deployment of btrfs, with some VERY interesting answers of BIG deployments of btrfs. Read success confirmed with data.
My takeaway from reading whole discussion: * lot of people (individuals) praise of btrfs * lot of people (ind.) tell about problems * quite nice features/btrfs usage patterns, not matched even by zfs mentioned * still for VM/DB you shall consider different approach (thin LVM + xfs or ext4) and slave machine WITH btrfs and snapshots on it * quite many problems/deficienses of ZFS mentioned (apart fomr typical license/kernel inclusion) * lot of new features on the way in recent kernels for btrfs * btrfs is not dead p.s. worth to comment that kernel 5.6 just received another huge new features batch for btrfs (async discard!) |
