Hi Ataraxy, sorry for the slow response.

As you noted, btrfsck is already installed as a symlink to btrfs, and I'm hesitant to break with the behaviour of the non-git package in [core] and install a standalone binary instead. The binary is built by default though (the only one that isn't is btrfs-sb-mod), so I've added the install line commented out in package() for people to toggle on as and when they need to.

I needed to build my own btrfs-sb-mod to point at a root tree after a pvscan caused corruption.

Upstream builds three "internal" tools that make install skips:

  • btrfs-sb-mod — prints/edits superblock fields (root, generation…) and recomputes their checksums; last-resort rescue editing of corrupt SBs.
  • btrfsck — the original standalone fs checker; useful to cross-check suspicious results from the integrated btrfs check.
  • btrfs-corrupt-block — deliberately damages on-disk structures; powers upstream's own test suite, handy for recovery drills.

Could package() add:

  make btrfsck btrfs-corrupt-block btrfs-sb-mod
  install -m755 btrfsck btrfs-corrupt-block btrfs-sb-mod \
      "${pkgdir}/usr/bin/"

Caveat: btrfs-sb-mod currently writes truncated checksums on xxhash64 filesystems — update_block_csum()/check_csum_superblock() use the CRC32-sized global csum_size instead of btrfs_csum_type_size(), so patched superblocks show [DON'T MATCH] in dump-super.

I think it's something with my system. For the record, I also build in clean chroot, I checked and I am getting same issue while building btrfs-progs from repos.

WorMzy commented on 2025-03-18 12:49 (UTC)

Interesting point. You shouldn't need a btrfs filesystem (the tests provide their own, if required), but you will need to modprobe the btrfs kernel module if you don't have it loaded, or the tests will fail:

==> Starting check()...
  TEST     fsck-tests.sh
failed: modprobe btrfs
make: *** [Makefile:543: test-fsck] Error 1
==> ERROR: A failure occurred in check().
    Aborting...

If you want to bypass the tests entirely, use --nocheck, but I don't recommend it. BTRFS is fragile enough without having potentially broken utils interacting with it..

Does it matter what filesystem I am using? I do not use btrfs on my computer. I also have linux-lts 6.12.19-1 now. This is the error:

@micwoj92: I'm unable to reproduce that here (in a clean chroot). There may be more information in your $srcdir/btrfs-progs/tests/fsck-tests-results.txt file, but I suspect the build was bad. If you can reproduce it, you might want to try bisecting the problem and reporting upstream.

Check fails for me with

@EndlessEden: sure, I've added that in. I didn't include the btrfs- prefix though, I don't think that's needed since nothing else provides a hash-speedtest binary.

@wormzy -- can you include/build "hash-speedtest" as well. Its in the makefile, and is a benchmark of the various hashes btrfs filesystem module support.

Its used for getting platform-specific benchmarks, thus is incredibly useful for switching between checksumming. (which support was added upstream finally) See below for example.

Thanks for the heads up, 0e4ef622, I've refreshed the dep arrays based on upstream.
