Hello. I am experiencing "No space left on device" with a btrfs file
system, yet I cannot seem to find any exhausted resource. Could some
resource I do not know about be exhausted, or is this caused by
something else. Below is a trace of information that might be usefull,
please let me know if there is anything I can do to resolve the issue.

So I have ended up in a state where I can't delete files with rm.

the error I get is no space on device. however I'm not even close to empty.
/dev/sdb1 38G 27G 9.5G 75%
there is about 800k files/dirs in this filesystem

extra strange is that I can in another directory create and delete files.

So I tried pretty much all I could google my way to but problem 
persisted. So I decided to do a backup and a format. But when the backup 
was done I tried one more time and now it was possible to delete the 
directory and all content?

using the 3.5 kernel in ubuntu 12.10. Is this a known issue ? is it 
fixed in later kernels?

fsck /btrfs scrub and kernel log. nothing indicate any problem of any kind.

Hi,

I am new to btrfs, and just installed a new system with SLED 11 SP2 a
few days ago.

However the system seems to be in a real sad state now, saying there
is no free space left on the device even though there is about 8GB
left on the / filesystem.

A defragment works sometimes but then it goes back to the original
state a day or two later. Other times the command just won't respond.

I've had this happen with 2-3 systems now, is there a solution? I
can't keep going around to users machines and defragmenting all the
time !

Thanks,

Mark

Hey all,

I run into no space left on device on a virtualbox

After installing Debian 6 on a virtual machine
I tried installing the KDE desktop

The system HDD is 8Gb
Both root (/) and /home are btrfs
over LVM.

While installing the packages I run into:

no space left, need 4096, 4096 dealloc bytes, 1776283648 bytes_used, 0
bytes_reserved,
0 bytes_pinned, 0 bytes_readonly, 0 may use 1776287744 total

df shows only 74% used space on /

kernel used: stock debian 6 2.6.32-5-686

At the moment I cannot access it with normal boot, only recovery mode.

I can provide whatever info you would like as long as you think of a
way to load the normal system and not the recovery mode.

hi,

I have an 80GB external HDD with one btrfs partition. Latest kernel
module and btrfs-progs from "unstable" git repos.

# mount
[...]
/dev/sdb1 on /media/coolermaster type btrfs (rw)

# df -h
[...]
/dev/sdb1              75G   61G   15G  81% /media/coolermaster

It seems like i have 15GB free space on the btrfs formatted partition,
but when i try to create a file of 4GB on the btrfs filesystem i get the
following error:

root@alderaan:/media/coolermaster/tmp# dd if=/dev/zero of=foobar.img
bs=1024 count=4000K
dd: writing `foobar.img': No space left on device
3372894+0 records in
3372893+0 records out
3453842432 bytes (3.5 GB) copied, 321.087 s, 10.8 MB/s

syslog:

Dec  8 10:35:46 alderaan kernel: [30716.434747] device fsid
46489b7e62f254e0-e306291dd7724d8f devid 1 transid 283 /dev/sdb1
Dec  8 10:35:50 alderaan kernel: [30720.457774] space info full 36

Am i missing something (e.g. reserved space for root, etc.) obvious
here?

Thanks,
