Hi Eugen I configured auto.master and a mount point file auto.ceph with the following entry. I am wondering if you can show me what your autofs entry looks like? Thanks ceph -fstype=ceph,name=cephfs,conf=/etc/ceph/mini_conf.conf,secretfile=/etc/ceph/client.cephfs,noatime :/ On Mon, Jun 15, 2020 at 5:33 PM Eugen Block <eblock@nde.ag> wrote:

Hi guys,

I can mount my cephfs via mount command and access it without any problem.

Now I want to integrate it in autofs which is used on our cluster.

It seems this is not a popular approach and I found only this link:

https://drupal.star.bnl.gov/STAR/blog/mpoat/how-mount-cephfs

I followed the link but could not get it to work. I am wondering if this is possible at all?

We are using CentOS 7.8 and the ceph cluster is running nautilus 14.2.9

Thanks Eugen Your environment is different from mine, but I will take your example and keep exploring. Thanks! Cheers D On Wed, Jun 17, 2020 at 4:58 PM Eugen Block <eblock@nde.ag> wrote:

Hi,

the autofs on our clients is configured to use LDAP, so there's one more layer. This is the current setup:

# autofs on LDAP server /etc/sysconfig/autofs:SEARCH_BASE="ou=cephfs,ou=AUTOFS,[...]"

# LDAP config -fstype=ceph,name=autofs,secretfile=/etc/ceph/autofs.key,nodev,nosuid <mon1>,<mon2>,<mon3>:/path/to/share

Does this help?

Regards, Eugen

Thanks for these I was missing the x-systemd. entries. I assume these are necessary so booting does not 'hang' on trying to mount these? I thought the _netdev was for this and sufficient? -----Original Message----- To: Derrick Lin Cc: ceph-users Subject: [ceph-users] Re: mount cephfs with autofs Hi, With CentOS 7.8 you can use the systemd autofs options in /etc/fstab. Here are two examples from our clusters, first with fuse and second with kernel: none /cephfs fuse.ceph ceph.id=admin,ceph.conf=/etc/ceph/dwight.conf,ceph.client_mountpoint=/,x -systemd.device-timeout=30,x-systemd.mount-timeout=30,noatime,_netdev,no auto,x-systemd.automount,x-systemd.idle-timeout=30,ro 0 2 cephflax.cern.ch:6789:/ /cephfs2 ceph name=admin,secretfile=/etc/ceph/flax.admin.secret,x-systemd.device-timeo ut=30,x-systemd.mount-timeout=30,noatime,_netdev,noauto,x-systemd.automo unt,x-systemd.idle-timeout=30,ro 0 2 Cheers, Dan On Mon, Jun 15, 2020 at 9:27 AM Derrick Lin <klin938@gmail.com> wrote:
