Re: MDSs report damaged metadata - "return_code": -116

Hi Paul,

thanks for the hint.

I did a recursive scrub from "/". The log says there where some inodes with bad backtraces repaired. But the error remains.
May this have something to do with a deleted file? Or a file within a snapshot?

The path told by

# ceph tell mds.mds3 damage ls
2019-08-19 13:43:04.608 7f563f7f6700  0 client.894552 ms_handle_reset on v2:192.168.16.23:6800/176704036
2019-08-19 13:43:04.624 7f56407f8700  0 client.894558 ms_handle_reset on v2:192.168.16.23:6800/176704036
[
    {
        "damage_type": "backtrace",
        "id": 3760765989,
        "ino": 1099518115802,
        "path": "~mds0/stray7/100005161f7/dovecot.index.backup"
    }
]

starts a bit strange to me.

Are the snapshots also repaired with a recursive repair operation?

Thanks
Lars
