(Replying to myself as I'm not subscribed and can't reply to Duncan's message) Hi Duncan, Good catch, mounting with -o skip_balance does allow me to mount the disk properly. Scrubbing the partition once mounted results in 0 errors. I'm still going to keep this untouched for further

btrfs partition fails to mount - kernel BUG at ../fs/btrfs/extent-tree.c:1872

2016-08-24 Thread Robert Munteanu
Hi, Using Kernel 4.7.1 ( openSUSE Tumbleweed x86_64 ), btrfsprogs 4.7 I always get a hard lockup when trying to mount my btrfs root partition. This may be due to some previous errors which only manifested themselves now, as it's been converted from an ext4 partition. Using mount -o ro works.

BTRFS warnings in dmesg / scrub errors - Transaction aborted ( error -95 )

Hi, I have a btrfs partition which exhibits some strange behaviours: - btrfs scrub seems to force the filesystem in read-only mode - transactions aborted with error -95 For context, this is a partition converted from ext4 which 'survived' through the issues described at

The disk image (still) contains sensitive data so I can't share it unfortunately. What I can do is keep it untouched until Friday evening EEST and run any debugging commands that you might think of to trace down the source of the errors. Alternatively, if there's an easy and safe fix and

Hi, I have converted my root ext4 partition to btrfs. I used an USB stick to boot and used btrfs-convert. I also did a balance and defrag ( in that order ) , both when the fs was mounted. After logging in to KDE I quickly get a read-only filesystem. I've pasted the backtrace below Jun 11
