Hello,
Suppose I have in /etc/fstab:

Hi Josef,
which branch from your (or another?) repo should I try this on:
remotes/origin/HEAD -> origin/master
remotes/origin/enospc3c78455 Btrfs: fall back to non-inline if we
don't have enough space

Master, and make sure you've checked out a more recent fio from git to make sure
it's not a bug in fio. Thanks,

I print the insteresting part of syslog below.
I mount the disk with
mount -t btrfs -o compress,noatime,nodiratime,noacl,noexec,nosuid /dev/sdb1 /usb
The error parts in the syslog come from the the mistaken
"mount /usb" and the line
/dev/sdb1 /usbauto
defaults,noauto,noatime,nodiratime

Hi everybody,
I am interested to test how btrfs behaves when the underlying block
device starts returning permanent IO errors. To test this, I set up a
linear device-mapper, mapped to the block device and start IOs. At
some point, I switch the device-mapper's table to "error" table (using

So shrink_delalloc has grown all sorts of cruft over the years thanks to
many reworkings of how we track enospc. What happens now as we fill up the
disk is we will loop for freaking ever hoping to reclaim a arbitrary amount
of space of metadata, this was from when everybody flushed at the same tim

Hi,
I just got this oops on a computer running 3.4.2.
A few minutes before I had started "btrfs device scrub /" and had a
watcher process running "btrfs scrub status /" every 5 seconds. After
a few gigabytes of scrubbing, I got this crash.
The oops is transcribed from photos, so it may contain s
