similar to: 2.6.29-rc1: Cannot loopback mount btrfs formatted file

https://bugzilla.redhat.com/show_bug.cgi?id=807905 Currently if you specify the blocksize parameter to mkfs-opts with a btrfs filesystem, then it fails, because mkfs.btrfs interprets the -b option as meaning filesystem size. The first patch fixes this by disallowing blocksize (it cannot be mapped meaningfully into btrfs parameters). The second patch adds the full /sbin/mkfs.btrfs utility to the

Hi, Question is pretty simple: "How to change node size and leaf size on previously created partition?" Now, I know what most people will say: "you should''ve be smarter while typing mkfs.btrfs". Well, I''m intending to convert in place ext4 partition but there seems to be no option for leaf and node size in this tool. If it''s not possible I guess

Check for the return value of ''open_ctree()'' before dereferencing it.

hi, everyone I try to install a suse11 pv guest on redhat5.2 virtualization platform. But the startup process hung with messages: xen-vbd: registered block device major 202 xvda:<6>netfront: Initialising virtual ethernet driver. XENBUS: Waiting for devices to initialise:

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply

Currently, the following commands succeed. # cat /proc/swaps Filename Type Size Used Priority /dev/sda3 partition 8388604 0 -1 /dev/sdc8 partition 9765884 0 -2 # mkfs.btrfs /dev/sdc8 WARNING! - Btrfs v0.20-rc1-165-g82ac345 IS EXPERIMENTAL WARNING! - see

Hallo, linux-btrfs, please delete the option "-L" (for labelling) in "mkfs.btrfs", in some configurations it doesn''t work as expected. My usual way: mkfs.btrfs -d raid0 -m raid1 /dev/sdb /dev/sdc /dev/sdd ... One call for some devices. Wenn I add the option "-L mylabel" then each device gets the same label, and therefore some other programs

I've been running ssh-clients-2.3.0p1-4 on RedHat 7.0 and upgraded to 2.5.1p2-1 yesterday from ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/rpm/SRPMS/. I noticed that 2.5.1p2-1 ssh-add won't look for id_dsa.pub by default -- if I have no identity file it just says "/home/klotz/.ssh/identity: No such file or directory" The 2.5.1p1-1 I got from RedHat's rawhide site

Hello Developers, it seems that i discovered a bug in btrfs while testing it on a zSeries mainframe :-) ## Test environment: - IBM System z900 Mainframe - Debian SID with 64 Bit Kernel - GIT Sources from git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable.git - System runs as z/VM guest - 3 Virtual CPUs - 1 GB RAM Storage ## Initial Test Setup - Setup a Debian SID System with

hi, folks, how have you gone about reporting a p-value from a test when the returned value from a test (in this case a rank-sum test) is numerically equal to 0 according to the machine? the next lowest value greater than zero that is distinct from zero on the machine is likely algorithm-dependent (the algorithm of the test itself), but without knowing the explicit steps of the algorithm

After running ceph on XFS for some time, I decided to try btrfs again. Performance with the current "for-linux-min" branch and big metadata is much better. The only problem (?) I''m still seeing is a warning that seems to occur from time to time: [87703.784552] ------------[ cut here ]------------ [87703.789759] WARNING: at fs/btrfs/inode.c:2103

[Note I'm not bothering with 32 bit ppc any more since it is effectively obsolete.] Libguestfs now works on ppc64 using the 'direct' backend. You will need: - libguestfs 1.23.21 + 7f90aa0998 - supermin 4.1.x (only tested with supermin-4.1.5-2.fc21.ppc64, but earlier versions should work) - qemu-system-ppc64 compiled from git (qemu 1.4 & 1.6 known to be broken) -

Hi! I recently tried to mount a filesystem in RAID1 mode using loopback devices. I followed the instructions at [1]. Here''s exactly what I''ve done: $ dd if=/dev/zero of=raid1_0.img bs=1M count=500 $ dd if=/dev/zero of=raid1_1.img bs=1M count=500 $ mkfs.btrfs -m raid1 -d raid1 raid1_0.img raid1_1.img $ losetup /dev/loop0 raid1_0.img $ losetup /dev/loop1 raid1_1.img $ mount -t

These patches fix btrfs on aarch64. You still need btrfs-progs 4.4 which was only released a few days ago. Rich.

Hi, I''ve some btrfs fs which are encrypted with loopaes. I decrypt them in a script during bootup. Now I want to determine if the decrypted fs is a btrfs fs. If not I missspelled the password and I can handle that error in my script. Thanks for any help!
