Subject: btrfs-convert: Unable to find block group for 0
Date: Fri, 24 Jun 2016 11:09:27 +0200 [thread overview]
Message-ID: <20160624090927.GD31030@abraxas.flw5.de> (raw)
While trying to convert a ext4 filesystem to btrfs with the new btrfs-convert from btrfs-progs-4.6 I
got the following error:
create btrfs filesystem:
blocksize: 4096
nodesize: 16384
features: extref, skinny-metadata (default)
creating ext2 image file.
Unable to find block group for 0
extent-tree.c:289: find_search_start: Assertion `1`
failed.
./btrfs-convert(btrfs_reserve_extent+0x8e9)[0x41979d]
./btrfs-convert(btrfs_alloc_free_block+0x50)[0x419b27]
./btrfs-convert[0x40b8d8]

Before I already tried btrfs-convert from btrfs-progs-4.5.2 which I
accidentally aborted but until then seemed to run fine.
