            Bug ID: 217604
           Summary: Kernel metadata repair facility is not available, but
                    kernel has CONFIG_XFS_ONLINE_REPAIR=y
           Product: File System
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: XFS
          Assignee: filesystem_xfs@kernel-bugs.kernel.org
          Reporter: j.fikar@gmail.com
        Regression: No

Hi,

I'm trying the new xfs_scrub and I get this error:

$ sudo xfs_scrub /mnt/xfs
EXPERIMENTAL xfs_scrub program in use! Use at your own risk!
Error: /mnt/xfs: Kernel metadata repair facility is not available.  Use -n to
scrub.
Info: /mnt/xfs: Scrub aborted after phase 1.
/mnt/xfs: operational errors found: 1

But the XFS_ONLINE_SCRUB and XFS_ONLINE_REPAIR are enabled in my kernel:

$ zcat /proc/config.gz | grep XFS
CONFIG_XFS_FS=y
CONFIG_XFS_SUPPORT_V4=y
# CONFIG_XFS_QUOTA is not set
CONFIG_XFS_POSIX_ACL=y
# CONFIG_XFS_RT is not set
CONFIG_XFS_ONLINE_SCRUB=y
CONFIG_XFS_ONLINE_REPAIR=y
# CONFIG_XFS_WARN is not set
# CONFIG_XFS_DEBUG is not set
# CONFIG_VXFS_FS is not set

I'm on kernel 6.3.8 and xfsprogs 6.3.0. Do I need to enable XFS_DEBUG as well?

xfs_scrub -n seems to run fine.

We haven't merged all the online repair code yet so it is not yet
available to use. Please close the bug and monitor the upstream XFS
list to find out when the repair code is fully merged and enabled
at runtime.

FWIW, it is far better to send a message to the mailing list
(linux-xfs@vger.kernel.org) to find out what the status of something
is than it is to raise a bug just to ask a question about support...

-Dave.

OK Dave, I'll do that. Maybe the help for XFS_ONLINE_REPAIR can mention that it
is not yet working, to avoid future confusion.

Actually, I was reporting another kernel bug (vmalloc error), which was
probably seen before and currently it is in network drivers (no idea, why it is
there).

I'm telling you, as it might be XFS related. I see the bug exactly once a day
and when I look at my cron.daily jobs, it happens during xfs_fsr run.

Both kernel and userspace yell EXPERIMENTAL when you invoke any part of
the online fsck system; I thought that was sufficient...
