Hi,
Ext4 metadata checksums feature was merged into Linux 3.6. Can I use
it out of the box with Fedora kernel or is there some magic switch to
enable it?
Are there any plans to support it in e2fsprogs shipped in Fedora -
backport or rebase to 1.43 version?
Last but equally important - how stable this feature is? Do anyone has
any experience with it?
I've been using it for a few months, and whilst it hasn't yet found any
corruption that would otherwise have been missed (which probably means
my drives are good!), it also hasn't been the cause of any.
Now, the inline_data patches were a whole world of pain...
There is no 1.43 released yet, latest is 1.42.7 which I just built in rawhide.
The "WIP" branch in git has the metadata checksum bits, so you could play
with that if you want.
I have a .srpm of it I can upload somewhere if you are interested.
I have no plans to backport unreleased upstream work in progress to Fedora,
I don't think that'd be wise.
To be honest, I haven't yet done a whole lot of testing with it myself,
yet.
