Hi Robert,

the logrotate file is recreated via cephadm itself (/var/lib/ceph/{FSID}/cephadm.{SOMEHASH}) when it issues its periodic checks every couple of minutes:

---snip---
LOGROTATE_DIR = '/etc/logrotate.d'
...
        self.logrotate_dir: str = LOGROTATE_DIR
...
    if not os.path.exists(ctx.logrotate_dir + '/cephadm'):
        with open(ctx.logrotate_dir + '/cephadm', 'w') as f:
            f.write("""# created by cephadm
/var/log/ceph/cephadm.log {
    rotate 7
    daily
    compress
    missingok
    notifempty
    su root root
}
""")
---snip---

Regards,
Eugen

Zitat von Robert Sander <r.san...@heinlein-support.de>:

Hi,

I have a cephadm managed 19.2.2 cluster where logrotate is unable to run because of a configuration conflict.

The package ceph-common is installed for all the command line tools and provides /etc/logrotate.d/ceph-common to rotate all logfiles in /var/log.

Some process now regularily creates /etc/logrotate.d/cephadm to rotate only /var/log/cephadm.log. And this creates a conflict for logrotate which refuses to run in the end.

I tried to remove /etc/logrotate.d/cephadm with rm just to see it reappear after a few minutes. The package cephadm is not installed.

I have not seen an entry in the MGR or MON log mentioning the creation of this file.

Which process is doing this?

Regards
