Hi Yang, ceph is working with udev. There is nothing in /etc/fstab.
---- If you are using root, you have rights on everything. If you are not using root, you have not. If you run ceph-deploy as root, all commands on the target host will be executed as root. If you run ceph-deploy as non root, all commands on the target host will be executed as this non root user ( with its rights ). So its just natural that you have different results, if you access with a user which has rights on everything and can do everything, compared to a user who has not this rights. With the hammer release you are using, you should / have to stick to the user root. Everything else might cause trouble. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:[email protected] Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 24.03.2016 um 04:04 schrieb yang: > Anyone who can help me? > > > ------------------ Original ------------------ > From: "yang";<[email protected]>; > Date: Wed, Mar 23, 2016 11:30 AM > To: "ceph-users"<[email protected]>; > Subject: root and non-root user for ceph/ceph-deploy > > Hi, everyone, > > In my ceph cluster, first I deploy my ceph using ceph-deploy with user root, > I don't set up any thing after it's setup, > to my surprise, the cluster can auto-start after my host reboot, all thing is > ok, mon is running and OSDs of device is mounted itself and also running > properly.
