similar to: problems with dracut mounting subvols

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

Is btrfs subvol support failing just for me? Looks like nothing adds the required '@/' string. virt-ls uses the first variant of the command: ><rescue> mount -vo subvol=var/spool,ro /dev/sda2 /sysroot/ [ 113.852047] BTRFS info (device sda2): disk space caching is enabled [ 113.852869] BTRFS: has skinny extents mount: mount(2) failed: No such file or directory ><rescue>

Setting subvolume/snapshot readonly has been missing for a long time.

Hello Hendrik Can you help input 2 commands 'mount' and 'df -TPh' on OMV, and post the output to us, thank you. -- Regards, Jones Syue | ??? QNAP Systems, Inc.

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. # btrfs subvolume

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. -- To unsubscribe from this list: send the line

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. Gene -- To unsubscribe from this

I thought I would try btrfs on a new installation of f14. yes, I know its experimental but stable so it seemed to be a good time to try it. I am not sure if I have missed something out of all my searching but am I correct in thinking that currently: I. it is not possible to boot from a snapshot of the operating system and, in particular, the yum snapshots cannot be used for

This fixes the issue I had come across with the default subvolume not being set/used on btrfs when isntalling via `extlinux --install /boot/syslinux`.

Hi, I will send a series patches that add snapshot/subvol deletion soon. But the way to delete snapshot/subvol is far from people''s expectancy. To delete a snapshot/subvol, we need four steps: 1) snapshot/subvol deletion ioctl or rmdir; 2) umount; 3) btrfsck; 4) mount the fs. The reason for this is bug in root back & forward references. In simple terms, the bug prevents us from

Add a mount option user_subvol_rm_allowed that allows users to delete a (potentially non-empty!) subvol when they would otherwise we allowed to do an rmdir(2). We duplicate the may_delete() checks from the core VFS code to implement identical security checks (minus the directory size check).

From: Anand Jain <anand.jain@oracle.com> (This patch is for the review/test not yet for the integration). Here is an implementation of the feature to add label to the subvolume and snapshots. Which would help sysadmin to better manager the subvol and snapshots. This can be done in two ways, one - using attr which is user land only changes but drawback is able to change the label

Very low priority. No user data at risk. 8GB virtual disk being installed to, and the installer is puking. I''m trying to figure out why. I first get an rsync error 12, followed by the installer crashing. What''s interesting is this, deleting irrelevant source file systems, just showing the mounts for the installed system: [root@localhost tmp]# df Filesystem

Hi, kickstarting fails due to problems with host resolution, even though the network seems to be properly configured through DHCP. eno1 and eno2 are both attached to the network, but only eno1 gets an IP via DHCP. Still `curl` cannot resolve the mirror host and the kickstart host during dracut-initqueue: rdsosreport.txt ------------------------------------------------ [...] [ 14.780428]

Initially, I just rebooted from LiveCD and left Grub,kernel and dracut do their job with the defaults, but unfortunately, boot process stops at initrd (dracut) stage with the following error: [ 197.768159] localhost.localdomain dracut-initqueue[252]: Warning: Could > not

Hi Chris, This is the extent of my current queue of Btrfs snapshot/subvol/commit stuff. Most of these were posted several months ago. Can be sent upstream during this merge window? Not having this functionality is becoming a bit of a roadblock for our efforts to keep the Ceph data in a consistent state. These patches are also available from

Guys, I have a Packer build procedure, that works like a charm, when with CentOS 6.7. Exemplifying: 1- Packer (with virtio disk) + QEmu + CentOS 6.7 ISO; 2- Create a RAW image; 3- Convert the RAW image into QCOW2 for KVM hypervisors (okay); 4- Convert the RAW image into VMDK for ESXi hypervisors (okay). However, when doing the very same procedure, with CentOS 7.2 ISO, it does not boot
