[PATCH] Improve support for exporting btrfs subvolumes.
If you export two subvolumes of a btrfs filesystem, they will both be
given the same uuid so lookups will be confused.
blkid cannot differentiate the two, so we must use the fsid from
statfs64 to identify the filesystem.
We cannot tell if blkid or statfs is best without knowing internal
details of the filesystem in question, so we need to encode specific
knowledge of btrfs in mountd. This is

I stream read - stale NFS file handle (reboot of server)
In the old days NFS Shared Path had a static handle (ie a number),
normal based on some number pulled out of the file system/inode.
To fix (well work around) a security issue, for about 10+ years now,
when a NFS server reboots, it generates a new random handle for the NFS
Share. (sever may generate a new random handle per mount request)
The NFS Stale Handle happens when the client is still

/boot as a btrfs subvolume
As of the latest updates to anaconda and grub2 for Fedora 18, it is now
possible to install with /boot as a btrfs subvolume. The way that grub2
is handling this is the "reach down" to the files it needs as if the
subvolume was a directory.
Is this OK?
At this point I am not worried about snapshots or any other
complexities. If the subvolume name is known. should grub2 be able to

Cannot set-default back to ID 0
Hi,
a recent Ubuntu upgrade killed my system. Luckily I had done a btrfs
snapshot before, so I set the particular subvolume as default using
# btrfs subvolume set-default 261 /mnt
from a rescue system and was back up in no time. I then mounted the
original volume with subvolid=0 and repaired it. So far so good.
However, I fail to set the default volume back to the original.

[PATCH 1/3] Btrfs-progs: add support to set subvolume/snapshot readonly
Setting subvolume/snapshot readonly has been missing for a long time.
With this patch, we can set a subvolume/snapshot readonly via:
o btrfs subvolume set-ro <path>

subvolid=0, ls hangs.
I''ve been running BTRFS for a while testing out various stuff, and I''ve
found it to be quite stable (although reading this list makes me realize
how much activity there really is).. I just hit my first bump in the
road, and I wondered if someone could give me a hint how I can gather
enough information to be useful here.
Basically, the filesystem I''m running is a 2 disk

subvolume show
I was looking through some of the archives and notice a patch submitted
to implement:
btrfs subvolume show <path-to-subvolume>
command.
I also noticed that is does not appear to be in the git.
This looks like a useful capability. I was trying to find out what the
UUID was for a newly created subvolume and have not found out how to do
that.

problems with dracut mounting subvols
I've just tried putting usr in a subvol. Installation proceeds normally, no errors, but I'm dropped to a dracut prompt which indicates mount of /usr failed. dmesg follows:

nfs4 help needed
Fedora 13 is using nfs4, and there is a problem in opening files requiring
OpenOffice if accessed over an nfs3 mount, so it's time to change. I found a
couple of tutorials, and got it *almost* working correctly. This is where I
need help.
Logwatch tells me
/nfs4exports/Data1 and /Data1 have same filehandle for
*,192.168.0.0/24,192.168.0.0/255.255.255.0, using first

Create subvolume from a directory?
Hi all,
Just a quick question but can''t find an obvious answer.
Can I create/convert a existing (btrfs) directory into a subvolume?
It would be very helpful when transferring ''partitions'' into btrfs.
I found a similar question way back in google, but that site is
down now generally.
Thanks in advance.

missing btrfs subvol support
Is btrfs subvol support failing just for me? Looks like nothing adds the
required '@/' string. virt-ls uses the first variant of the command:

btrfs problems and fedora 14

I am not sure if I have missed something out of all my searching but am

fstrim on BTRFS
Hi!
With 3.2-rc4 (probably earlier), Ext4 seems to remember what areas it
trimmed:
merkaba:~> fstrim -v /boot
/boot: 224657408 bytes were trimmed
merkaba:~> fstrim -v /boot
/boot: 0 bytes were trimmed
But BTRFS does not:
merkaba:~> fstrim -v /
/: 4431613952 bytes were trimmed
merkaba:~> fstrim -v /
/: 4341846016 bytes were trimmed

Modifying files of NFS
Hi,
I have an NFS storage system and want to run jpegoptim on several GB's
of jpeg images and I'm wondering what the best approach is.
Is it ok to run this operation on the Server itself while the clients
have it mounted or will this lead to problems like e.g. the dreaded
"stale filehandle"?

Hi Everyone,
I have been trying to setup an NFS v4 File Server but have come across
an odd issue. Mounting the /nfs4exports/share appears to be successful
and the information displayed about partition size and free space seem

service restart failures
Puppet is failing to restart lighttpd using the Debian init script.
Both the default action of stop/start and using the reload action, which
basically does the same thing, fail.
It seems to be a filehandle problem. Changing the execute method
in service.rb to redirect stdout to /dev/null allows the daemon to
restart. Otherwise, I end up with a zombie process and according to
