Introduction 1.1. Project/Component Working Name: ZFS snapshot properties 1.2. Name of Document Author/Supplier: Author: Matthew Ahrens 1.3 Date of This Document: 29 July, 2008 4. Technical Description This case requests patch/micro release binding. The new interfaces are committed. A. INTRODUCTION ZFS stores properties on filesystems and volumes. These properties are manipulated with "zfs set", "zfs inherit", "zfs list", and "zfs get". Properties fall into several categories: * read-only properties, which are set by the system and report on the state of the filesystem or snapshot (eg, space used). * modifiable system properties, which users can change and which affect ZFS behavior (eg, atime, setuid, quota) * user properties, which system administrators can set but which do not affect ZFS behavior. Administrators may define user properties using names of their choosing. (eg, com.sun:billingdepartment) Until now, properties on snapshots can not be modified; the modifiable system properties which affect snapshots (eg, setuid, exec) always inherit their setting from the containing filesystem or volume. B. DESCRIPTION This case adds the ability to set properties on snapshots. This includes system properties that affect snapshots (devices, exec, setuid, xattr, nbmand) and user properties. Set-once properties (eg, normalization) can not be set on snapshots. The "zfs set" and "zfs inherit" commands can now be used on snapshots. Additionally, "zfs snapshot" will take a "-o property=value" option (which can be specified multipe times to set many properties). "zfs send -R" will send snapshot properties. Old software versions which do not understand snapshot properties will ignore them when doing a "zfs recv" of such a stream. The zpool on-disk version number will be incremented, and snapshot properties can only be set on upgraded pools. C. MANPAGE CHANGES To be determined. 6. Resources and Schedule 6.4.
