Greetings.
Suddenly, a filesystem on SSD became corrupted. None of the usual repair

check_tree_block complains (have=0) for blocks in root (?), I have modified it
to print
buf->data and for affected blocks the entire header is filled with zeros.
I have a full image if anyone wa
Hello,
I tried to use "bedup" BTRFS offline deduplication tool on several BTRFS

1/ Crashes with messages stating "programming error", sqlite objects must be
used inside of the thread that created them, blah-blah...
2/ Crashes stating that some file/objects miss a

doing so with Debian kernel 3.12.8.
This is not the first time I've seen a filesystem corruption occur related to
Kmail files that causes a kern

I just had a system with a single 120G Intel SSD and 54G of data stored take 3
hours for a balance.
Balance seems to be a very slow operation and it

Btrfs send reads data from disk and then writes to a stream via pipe or
a file via flush.
Currently we're going to read each page at a time, so every page results
in a disk read, which is not friendly to disks, esp. HDD. Given that,
