Send/Receive Support For Btrfs Published
Phoronix: Send/Receive Support For Btrfs Published
Experimental patches were published this week for the Btrfs file-system for "send/receive" support, which requires changes to btrfs-progs and the Btrfs kernel module that allow for creating a stream of instructions that can be replayed later...
Right now I am done with BTRFS
I make my home partition BTRFS when installing Ubuntu 11.04(later updated to 11.10). After 2-3 months my system becomes too slow whenever its read data from home, specially Chrome took 1.5 min to open. Also some strange warning massage when starting Linux. Since I install 12.04 and make my home drive EXT4 again(also keep all the former data from previous home partition, my pc becomes much more faster, Chrome now take 5s(I keep all files from old home directory so Chrome still take same/more data while starting). I am all done with BTRFS and not going to use it for at least next 2 years.
Installed it two days ago. Removed it yesterday.
I was setting up a Linux partition on a multiboot system the other day, and went with btrfs. Then, when playing with grub and the hidden boot options (I didn't want the menu to appear unless shift was held), I somehow managed to get the system hosed up such that it booted the default (not Linux) OS and shift/esc would *not* interrupt/unhide GRUB for some reason.
So, "simple enough" I thought... I would just boot from a liveCD, chroot into the installed partition, fix /etc/default/grub and re-run update-grub - right?
That's where the real problem started: Have you tried to chroot into a root-level btrfs partition? I tried all kinds of things from two different live distros (including the install media I had originally used), and *never* could get it to work.
I ended up re-installing the partition from scratch as EXT4. I then managed to get into almost the exact same GRUB problem (this time after I manually edited /etc/grub.d/00_* to try to work around the original issue), but was able to chroot to the EXT4 partition to fix it with no difficulty whatsoever (so I know that what I was originally doing with btrfs was valid - it just won't work with that file system).
Long story short - I'm still wary of btrfs and only use/test it for auxiliary partitions that I really don't care about or that have reliable backups.
