"head_errlog" features missing in master branch

[Loykos]

Hi everyone,

I had my pool attached on my Mac OS X system (with 2.1.6 zfs version from this repo). It's ask me to upgrade the pool enabling "head_errlog" feature. So I did.. I have another Rhel9 home server with 2.1.9 version, so I didn't think it could be a problem.

When I try to import the pool from the rhel, I discovered that this feature it's not present in the 2.1.9 version, but it should be present only inside the master branch (link) (I don't know why this feature is inside the 2.1.6 osx version).

So I cloned the repo, checked out the master and built the package from source. Unfortunately if I execute the zpool executable inside the folder it still gives me that the "com.delphix:head_errlog" features is missing when I try to import the pool.

Is this feature inside the master or not? Which branch I should checkout?

[loykos@localhost zfs]$ git branch
* master

[loykos@localhost zfs]$ ./zpool --version
zfs-2.1.99-1817_gb15ab50c4
zfs-kmod-2.1.9-1

[loykos@localhost zfs]$ sudo ./zpool import pool
This pool uses the following feature(s) not supported by this system: com.delphix:head_errlog (Support for per-dataset on-disk error logs.) org.openzfs:zilsaxattr (Support for xattr=sa extended attribute logging in ZIL.) cannot import 'pool': unsupported version or feature

Thanks!

You're running the 2.1.9 kernel modules, which don't have support for that. (cf. where it says zfs-kmod-2.1.9-1 in the version output.)

You're right. I solved installing latest 2.1.99 version kernel module. Thank you!
