* Systemd mount generator: Generate noauto units; add control propertiesInsanePrawn2020-02-141-26/+191
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit refactors the systemd mount generators and makes the following major changes: - The generator now generates units for datasets marked canmount=noauto, too. These units are NOT WantedBy local-fs.target. If there are multiple noauto datasets for a path, no noauto unit will be created. Datasets with canmount=on are prioritized. - Introduces handling of new user properties which are now included in the zfs-list.cache files: - org.openzfs.systemd:requires: List of units to require for this mount unit - org.openzfs.systemd:requires-mounts-for: List of mounts to require by this mount unit - org.openzfs.systemd:before: List of units to order after this mount unit - org.openzfs.systemd:after: List of units to order before this mount unit - org.openzfs.systemd:wanted-by: List of units to add a Wants dependency on this mount unit to - org.openzfs.systemd:required-by: List of units to add a Requires dependency on this mount unit to - org.openzfs.systemd:nofail: Toggles between a wants and a requires dependency. - org.openzfs.systemd:ignore: Do not generate a mount unit for this dataset. Consult the updated man page for detailed documentation. - Restructures and extends the zfs-mount-generator(8) man page with the above properties, information on unit ordering and a license header.

* Workaround to avoid a race when /var/lib is a persistent datasetDidier Roche2019-10-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If /var/lib is a dataset not under <pool>/ROOT/<root_dataset>, as proposed in the ubuntu root on zfs upstream guide (https://github.com/zfsonlinux/zfs/wiki/Ubuntu-18.04-Root-on-ZFS), we end up with a race where some services, like systemd-random-seed are writing under /var/lib, while zfs-mount is called. zfs mount will then potentially fail because of /var/lib isn't empty and so, can't be mounted. Order those 2 units for now (more may be needed) as we can't declare virtually a provide mount point to match "RequiresMountsFor=/var/lib/systemd/random-seed" from systemd-random-seed.service. The optional generator for zfs 0.8 fixes it, but it's not enabled by default nor necessarily required. Example: - rpool/ROOT/ubuntu (mountpoint = /) - rpool/var/ (mountpoint = /var) - rpool/var/lib (mountpoint = /var/lib) Both zfs-mount.service and systemd-random-seed.service are starting After=systemd-remount-fs.service. zfs-mount.service should be done before local-fs.target while systemd-random-seed.service should finish before sysinit.target (which is a later target). Ideally, we would have a way for zfs mount -a unit to declare all paths or move systemd-random-seed after local-fs.target.

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.

* Add kernel module auto-loadingBrian Behlendorf2018-03-133-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically a dynamic misc minor number was registered for the /dev/zfs device in order to prevent minor number collisions. This was fine but it prevented us from being able to use the kernel module auto-loaded which requires a known reserved value. Resolve this issue by adding a configure test to find an available misc minor number which can then be used in MODULE_ALIAS_MISCDEV at build time. By adding this alias the zfs kmod is added to the list of known static-nodes and the systemd-tmpfiles-setup-dev service will create a /dev/zfs character device at boot time. This in turn allows us to update the 90-zfs.rules file to make it aware this is a static node. The upshot of this is that whenever a process (zpool, zfs, zed) opens the /dev/zfs the kmods will be automatic loaded. This even works for unprivileged users so there is no longer a need to manually load the modules at boot time. As an additional bonus the zed now no longer needs to start after the zfs-import.service since it will trigger the module load. In the unlikely event the minor number we selected conflicts with another out of tree unregistered minor number the code falls back to dynamically allocating it. In this case the modules again must be manually loaded. Note that due to the change in the method of registering the minor number the zimport.sh test case may incorrectly fail when the static node for the installed packages is created instead of the dynamic one. This issue will only transiently impact zimport.sh for this single commit when we transition and are mixing and matching methods.

| | | | | | | | | | | | | | | | | | | | The mount(8) command will helpfully try to resolve any device name which is passed in.

If that resulting directory name exists mount(8) will perform the mount(2) system call and never invoke the helper utility. Since the cwd for systemd when running as the system instance is the root directory the default mount points created by zfs(8) can cause a mount failure.

* Support parallel build trees (VPATH builds)Turbo Fredriksson2015-07-171-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake. Makefile.am:00: warning: source file 'xxx' is in a subdirectory, Makefile.am:00: but option 'subdir-objects' is disabled Signed-off-by: Turbo Fredriksson <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #1082
* Use ExecStartPre to load zfs modulesBrian Behlendorf2015-05-262-2/+4
| | | | | | | | | | | | | Commit 87abfcb broke the systemd import service by treating the ExecStart line as if it were a shell command that could be executed. This isn't the way systemd works and the correct way to handle this case is with ExecStartPre. This patch updates the zfs import service files accordingly, Signed-off-by: Brian Behlendorf <[email protected]> Signed-off-by: Steven Noonan <[email protected]> Signed-off-by: Chris Siebenmann <[email protected]> Closes #3440
* Wait in libzfs_init() for the /dev/zfs deviceBrian Behlendorf2015-05-222-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While module loading itself is synchronous the creation of the /dev/zfs device is not. This is because /dev/zfs is typically created by a udev rule after the module is registered and presented to user space through sysfs. This small window between module loading and device creation can result in spurious failures of libzfs_init(). This patch closes that race by extending libzfs_init() so it can detect that the modules are loaded and only if required wait for the /dev/zfs device to be created. This allows scripts to reliably use the following shell construct without the need for additional error handling. $ /sbin/modprobe zfs && /sbin/zpool import -a To minimize the potential time waiting in libzfs_init() a strategy similar to adaptive mutexes is employed. The function will busy-wait for up to 10ms based on the expectation that the modules were just loaded and therefore the /dev/zfs will be created imminently. If it takes longer than this it will fall back to polling for up to 10 seconds. This behavior can be customized to some degree by setting the following new environment variables. This functionality is provided for backwards compatibility with existing scripts which depend on the module auto-load behavior. By default module auto-loading is now disabled. * ZFS_MODULE_LOADING="YES|yes|ON|on" - Attempt to load modules. * ZFS_MODULE_TIMEOUT="<seconds>" - Seconds to wait for /dev/zfs The zfs-import-* systemd service files have been updated to call '/sbin/modprobe zfs' so they no longer rely on the legacy auto-loading behavior.
