Hello,
thanks for letting me know.
Indeed it would be good to replace the segmentation Fault by btrfs
does not yet know how to handle this condition.
Future refinements of btrfsck will probably include proper error
messages for issues that can't be handled, or perhaps even fix the
error.
Hi,
4. support this scene,
When doing the receive process, if it suddently be stopped,
how to continue the receive process.
I sent a proposal and a patch to implement this in
http://www.spinics.net/lists/linux-btrfs/msg19387.html. However, it is
not easy to make this patch

Mohit, Nafisa,
you should start reading from changed_cb function, which is the one
that notifies the send code about a particular change that needs to be
addressed.
The lowest-level instruction generation happens in functions like
send_rename, send_link, send_unlink, send_truncate etc.

Hi!
I have BTRFS on some systems since more than two years. My experience so
far is: Performance at the beginning is pretty good, but some of my more
often used BTRFS filesystem degrade badly in different areas. On some
workloads pretty quickly.
There are also some fs however that did not

Hi,
I'm hitting a btrfs locking issue with 3.7.0-rc8.
The btrfs filesystem in question is backing a Ceph OSD
under a heavy write load from many cephfs clients.
I reported this issue a while ago:

Dear Mich,
thanks for your help and suggestion:
It might be interesting for you to try a newer kernel, and use scrub
on this volume if you have the two disks RAIDed.
I have now scrubbed the Disk:
./btrfs scrub status /mnt/other/
scrub status for a15eede9-1a92-47d8-940a-adc7cf97352d
