comment Does this bug indicate an error in my btrfs filesystem of simply a bug in the 4.2.0-RC5 kernel?
@frostschutz: For future reference, where's the best place to report btrfs kernel bugs? Opensuse wouldn't be an obvious choice to me.

comment How do I copy a folder keeping owners and permissions intact?
I don't think there is (although there may once have been and may still be on some versions of Unix). See man7.org/linux/man-pages/man1/cp.1.html It simply says -R, -r, --recursive copy directories recursively.

comment Show mounted btrfs subvolumes?
@user1902689: I don't understand your comment. If I mount a btrfs subvolume using mount -tbtrfs -osubvol=home,compress=zlib,autodefrag,recovery /dev/sdc /home then /etc/mtab contains a line /dev/sdc /home btrfs rw,relatime,compress=zlib,space_cache,autodefrag,recovery 0 0. The subvol=... option isn't included. What are you referring to?

comment Why does btrfs refuse to convert metadata to RAID1
I only recently started looking at BTRFS. Having converted an ext4 filesystem, I wanted to upgrade the metadata to DUP, and spent some time trying to figure out what I was doing wrong and why it stubbornly stayed as SINGLE! Now I know.

comment Command 'pvs' says PV device not found, but LVs are mapped and mounted
@Bratchley: my point is that you were suggesting something I'd already tried. If you have a suggestion as to how I can get more detailed information, without simply rebooting, then I'd be happy to try it. Currently pvscan -vvvv (with or without lvm2-lvmetad running) doesn't reference the 'missing' RAID device except to add it to the device cache and note its aliases. pvdisplay -vvvv /dev/md99 obviously finds the device, as it reports the correct UUID, VG, etc from libdm-config.c near the start, but then reports "Failed to find physical volume" at the end!

@Bratchley, by the way, if you read my comment to derobert, you'd have realised that I've already tried a pvscan (several times).

comment Command 'pvs' says PV device not found, but LVs are mapped and mounted
I've been using LVM for about 5 years; I know what pvscan is. My point was that I wanted to avoid rebooting the machine since that will almost certainly fix the problem. What I wanted was some way to get LVM back to a consistent state without rebooting. I get the impression this isn't possible. Since LVs in the 'missing' VG can be mounted, I've taken the precaution of copying the data to a new set of LVs in a new VG and will probably reboot later this evening. I expect this will fix the issue, but won't provide info as to why it happened in the first place and if an online fix can be done.
