I recently released e2fsprogs 1.44.0 (currently in Debian Unstable, should hopefully hit Debian Testing in three more days) which turns on Metadata Checksums for everyone.
https://packages.debian.org/sid/e2fsprogs Pulling in 1.44.0 supports two new features, largedir and ea_inode, (neither turned on by default yet, but the second in particular is very useful for Samba servers since it was written specifically to efficiently support Windows ACL's and Security ID's better than any other file system by supporting xattr dedupe.) http://e2fsprogs.sourceforge.net/e2fsprogs-release.html#1.44.0 In general e2fsprogs has a very conservative release process, and there have been a *large* number of bug fixes since e2fsprogs 1.42.13. (Including some that can cause horrible file system corruption and data loss if you do off-line resize2fs operations (resizing the file system while the file system is not mounted) under some circumstances. So if you are using distribution with that has e2fsprogs 1.42.13, on the misguided assumption that staying on an ancient version of e2fsprogs is "safer" --- that is simply not true. One caveat: in 1.44.0 I started relying on dpkg build profiles in debian/rules. This means e2fsprogs 1.44.0 no longer builds out of the box for Debian 7 (wheezy, aka Debian old-old-stable) and Ubuntu Trusty (14.04 LTS) and older releases. It should be possible to backport e2fsprogs 1.44.0 to 14.04 LTS, but at the very least 14.04 LTS should go to 1.43.9 to fix a huge number of bugs. But for 16.04, e2fsprogs 1.44.0 should just drop right in. And with 14.04 LTS and older, e2fsprogs 1.43.9 should Just Work. It wouldn't be that hard to make e2fsprogs 1.44.0 work on 14.04 LTS, but it won't be turn-key. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to e2fsprogs in Ubuntu. https://bugs.launchpad.net/bugs/1365874 Title: Ubuntu 12.04 LTS, 14.04 LTS, 16.04 LTS do not support ext4 metadata checksumming Status in e2fsprogs package in Ubuntu: Triaged Bug description: In the Trusty release notes "Metadata checksumming" is listed as one of the tech highlights of kernel 3.13. https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#New_features_in_14.04_LTS However, the userland tools do not support this kernel feature. To the best of my knowledge this will be supported in 1.43, and won't be backported to 1.42. IMHO this is very misleading. It's like a car salesperson sold you a sports car with an V8 engine. After you drove it home, you opened the hood and realized only 6 cylinders are working because 2 of the spark plugs were not included, and you have to buy aftermarket ones. <rant>BTW, I've been following the development of e2fsprogs for over a year. 1.43 release has been in limbo for God knows how long :( </rant> To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1365874/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
