Every filesystem has problems in the early days. Only a small minority of BTRFS problems caused data loss. I've had a few serious problems (including ones that required backup/format/restore) and none of them lost any data AFAIK.
How long do these "early days" last, btrfs has been around long enough to be more stable and trustworthy, but it isn't stable or trustworthy enough for me and many others. Heck, even Oracle declared it production ready quite some time ago, yet we are still seeing issue after issue -- no thanks!
Filesystems are getting increasingly complex due to the increasing demands on them. It takes a lot more work to develop a filesystem than it used to.
My impression is that the only way ZFS can be said to no longer have a RAM problem is that RAM is cheap enough that no ZFS server will have less than 8G and everyone knows to turn of dedup.
Did you even read what was already posted? " ... and I run ZFS on 3GB and 4GB RAM boxes ...." -- that's fine, but how much storage.
ZFS used to have serious problems with RAM requirements, I don't believe that is the case now from what I've been hearing.
I've had RAM problems on a system with 4G of RAM running not much apart from Samba. I don't think that zfsonlinux has changed much since then. ZFS just manages memory differently from anything that was developed for Linux. Changing that would require significant code changes which would be another potential source of stability problems.
The way Debian is going, it is looking like a real option to switch to FreeBSD with a very mature ZFS and to give up on Linux for some use cases and possibly end up not even having to worry about systemd or other things being pushed in to Debian by Red Hat people ever again. I am very sure that these issues will drive many AWAY from Linux in general and Debian in particular!
Systemd wasn't pushed in to Debian by Red Hat or anyone else. The Debian technical committee decided that systemd was the best option. After that decision there were a lot of threats and abuse by some people with obvious mental health problems. But such people don't matter when it comes to making a decision because they lack the intelligence or sanity to contribute to Debian in any way. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
