Have you tried "ceph daemon mds.NAME dump snaps" (available since mimic)? ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 ________________________________________ From: Lars Täuber <taeuber@xxxxxxx> Sent: 17 December 2019 12:32:34 To: Stephan Mueller Cc: ceph-users@xxxxxxx Subject: Re: list CephFS snapshots Hi Michael, thanks for your gist. This is at least a way to do it. But there are many directories in our cluster. The "find $1 -type d" lasts for about 90 minutes to find all 2.6 million directories. Is there another (faster) way e.g. via mds?
