Add systemd unit files for ZFS startup This adds systemd unit files replacing the functionality offered by the SysV init script found in etc/init.d. It has been developed and tested on Fedora 19, Fedora 20 and openSuSE 13.1. Four unit files and one target are offered. zfs-import-cache.service: Import pools from /etc/zfs/zpool.cache. This unit will wait for udev to settle. zfs-import-scan.service: Import pools by scanning /dev/disk/by-id for zvols. This unit will only run if /etc/zfs/zpool.cache is not present. This unit will wait for udev to settle zfs-mount.service: Mount ZFS native filesystems. It contains a dependency to be loaded before local-fs.target. zfs-share.service: Share NFS/SMB filesystems. This unit contains a dependency that will cause it to be restarted whenever the smb or nfs-server unit is restarted, restoring the shares added. zfs.target: This target pulls in the other units in order to start ZFS. It's the only unit that can be enabled/disabled, all other services are static and pulled in by dependencies. It will honour zfs=off and zfs=no options on the kernel command line.

Documentation=man:zfs(8)
Make zfs-share service resilient to stale exports The are a few cases where stale entries in /etc/exports.d/zfs.exports will cause the nfs-server service to fail when starting up. Since the nfs-server startup consumes /etc/exports.d/zfs.exports, the zfs-share service (which rebuilds the list of zfs exports) should run before the nfs-server service. To make the zfs-share service resilient to stale exports, this change truncates the zfs config file as part of the zfs share -a operation.

Wants=zfs-mount.service
Race between zfs-share and zfs-mount services When a system boots the zfs-mount.service and the zfs-share.service can start simultaneously. What may be unclear is that sharing a filesystem will first mount the filesystem if it's not already mounted. This means that both service can race to mount the same fileystem. This race can result in a SEGFAULT or EBUSY conditions. This change explicitly defines the start ordering between the two services such that the zfs-mount.service is solely responsible for mounting filesystems eliminating the race between "zfs mount -a" and "zfs share -a" commands.

Systemd configuration fixes * Disable zfs-import-scan.service by default. This ensures that pools will not be automatically imported unless they appear in the cache file. When this service is explicitly enabled pools will be imported with the "cachefile=none" property set. This prevents the creation of, or update to, an existing cache file. $ systemctl list-unit-files | grep zfs zfs-import-cache.service enabled zfs-import-scan.service disabled zfs-mount.service enabled zfs-share.service enabled zfs-zed.service enabled zfs.target enabled * Change services to dynamic from static by adding an [Install] section and adding 'WantedBy' tags in favor of 'Requires' tags. This allows for easier customization of the boot behavior. * Start the zfs-import-cache.service after the root pivot so the cache file is available in the standard location. * Start the zfs-mount.service after the systemd-remount-fs.service to ensure the root fs is writeable and the ZFS filesystems can create their mount points. * Change the default behavior to only load the ZFS kernel modules in zfs-import-*.service or when blkid(8) detects a pool. Users who wish to unconditionally load the kernel modules must uncomment the list of modules in /lib/modules-load.d/zfs.conf.
