Message-ID: <ZafXawnqlO7OvG1k@camel3.lan> Date: Wed, 17 Jan 2024 14:34:35 +0100 From: Matthias Reichl <hias@...us.com> To: Theodore Ts'o <tytso@....edu> Cc: linux-ext4@...r.kernel.org, hias@...us.com Subject: [e2fsprogs] resize2fs 1.47.0 creates unclean orphan file When resizing a 32 MiB ext4 filesystem that was created with the orphan_file option to something larger than 32GiB the resulting filesystem has an unclean orphan file block. I initially ran into this issue with e2fsprogs 1.47.0 on aarch64 but could also reproduce it with current e2fsprogs master (githash 260dfea450e387cbd2c8de79a7c2eeacc26f74e9) and e2fsprogs 1.47.0 from Debian Bookworm (the latter needs -O orphan_file as Debian disabled that option by default) on x86_64. resize2fs works fine if the target filesystem size is smaller than 32GiB (tested with 30GiB) or if the ext4 filesystem was created without the orphan_file option. Steps to reproduce: $ ./configure --with-root-prefix=/usr/local $ make $ truncate -s 32MiB fs $ ./misc/mke2fs -t ext4 -m 0 fs $ truncate -s 33GiB fs $ ./e2fsck/e2fsck -f -n fs e2fsck 1.47.0 (5-Feb-2023) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information fs: 12/8192 files (0.0% non-contiguous), 6970/32768 blocks $ ./resize/resize2fs fs resize2fs 1.47.0 (5-Feb-2023) Resizing the filesystem on fs to 34603008 (1k) blocks. The filesystem on fs is now 34603008 (1k) blocks long. $ ./e2fsck/e2fsck -f -n fs e2fsck 1.47.0 (5-Feb-2023) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information Orphan file (inode 12) block 2 is not clean.
