You should not use quotas on btrfs currently. It is known to cause significant performance issues on the long run (and potentially has many undiscovered bugs). If you wish I can dig up the relevant discussion on the btrfs mailing list for you.
Yes, I heard this but can't find relevant bugreports. The kernel wiki says that quotas are fully supported, at least with simplest (raid1?) setups.
Well, without quotas, I can just expect my filesystem to fill up, again, without warning, and completely break. I think I might just have to buy some extra disks, and try out ZFS for myself.
See this: http://marc.merlins.org/perso/btrfs/post_2014-05-04_Fixing-Btrfs-Filesystem-... Basically, when your btrfs is full, just create a loopback device, add it to the array, rebalance and then remove the device. This is what I had to do this Sunday :) Cheers, -- Leonid Isaev GPG fingerprints: DA92 034D B4A8 EC51 7EA6 20DF 9291 EE8A 043C B8C4 C0DF 20D0 C075 C3F1 E1BE 775A A7AE F6CB 164B 5A6D
