| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * contrib/initramfs: include /etc/default/zfs and /etc/zfs/zfs-functions At least debian needs /etc/default/zfs and /etc/zfs/zfs-functions for its initramfs.

This makes debians additional zdev hook unneeded. * Correct initconfdir substitution for some distros Not every Linux distro is using @sysconfdir@/default but @initconfdir@ which is already determined by configure. Let's use it. * systemd: prevent possible conflict between systemd and sysvinit Systemd will not load a sysvinit service if a unit exists with the same name. This prevents conflicts between sysvinit and systemd. In ZFS there is one sysvinit service that does not have a systemd service but a target counterpart, zfs-import.target. Usually it does not make any sense to install both but it is possisble. Let's prevent any conflict by masking zfs-import.service by default. This does not harm even if init.d/zfs-import does not exist.

* Race between zfs-share and zfs-mount servicesGeorge Wilson2019-07-281-0/+1
| | | | | | | | | | | | | | | | | | 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.

* Add kernel module auto-loadingBrian Behlendorf2018-03-134-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

We “need” to know how much we will dirty so that we can check if we should fail this transaction with ENOSPC/EDQUOT, in dmu_tx_assign(). While the transaction is open (i.e. between dmu_tx_assign() and dmu_tx_commit() — typically less than a millisecond), we call dbuf_dirty() on the exact blocks that will be modified. Once this happens, the temporary accounting in tx_space_* is unnecessary, because we know exactly what blocks are newly dirtied; we call dnode_willuse_space() to track this more exact accounting. The fundamental problem causing this bug is that dmu_tx_hold_*() relies on the current state in the DMU (e.g. dn_nlevels) to predict how much will be dirtied by this transaction, but this state can change before we actually perform the transaction (i.e. call dbuf_dirty()). This bug will be fixed by removing the assertion that the tx_space_* accounting is perfectly accurate (i.e. we never dirty more than was predicted by dmu_tx_hold_*()). By removing the requirement that this accounting be perfectly accurate, we can also vastly simplify it, e.g. removing most of the logic in dmu_tx_count_*(). The new tx space accounting will be very approximate, and may be more or less than what is actually dirtied. It will still be used to determine if this transaction will put us over quota. Transactions that are marked by dmu_tx_mark_netfree() will be excepted from this check. We won’t make an attempt to determine how much space will be freed by the transaction — this was rarely accurate enough to determine if a transaction should be permitted when we are over quota, which is why dmu_tx_mark_netfree() was introduced in 2014. We also won’t attempt to give “credit” when overwriting existing blocks, if those blocks may be freed. This allows us to remove the do_free_accounting logic in dbuf_dirty(), and associated routines. This logic attempted to predict what will be on disk when this txg syncs, to know if the overwritten block will be freed (i.e. exists, and has no snapshots).

* Fix zfs-mount.service failure on bootBrian Behlendorf2017-02-081-0/+1
| | | | | | | | | | | | | | | | | | | | The mount(8) command will helpfully try to resolve any device name which is passed in. It does this by applying some simple heuristics before passing it along to the registered mount helper. Normally this fine. However, one of these heuristics is to prepend the current working directory to the passed device name. 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. This change avoids the issue by explicitly setting the cwd to a different path when performing the mount. Signed-off-by: Brian Behlendorf <[email protected]> Closes #5719

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* A collection of dracut fixesManuel Amador (Rudd-O)2016-05-122-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | - In older systems without sysroot.mount, import before dracut-mount, and re-enable old dracut mount hook - rootflags MUST be present even if the administrator neglected to specify it explicitly - Check that mount.zfs exists in sbindir - Remove awk and head as (now unused) requirements, add grep, and install the right mount.zfs - Eliminate one use of grep in Dracut - Use a more accurate grepping statement to identify zfsutil in rootflags - Ensure that pooldev is nonempty - Properly handle /dev/sd* devices and more - Use new -P to get list of zpool devices - Bail out of the generator when zfs:AUTO is on the root command line - Ignore errors from systemctl trying to load sysroot.mount, we only care about the output - Determine which one is the correct initqueuedir at run time. - Add a compatibility getargbool for our detection / setup script. - Update dracut .gitignore files Signed-off-by: <Matthew Thode [email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #4558 Closes #4562

* zfs-import: Perform verbatim import using cache fileJames Lee2015-10-132-64/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change modifies the import service to use the default cache file to perform a verbatim import of pools at boot. This fixes code that searches all devices and imported all visible pools. Using the cache file is in keeping with the way ZFS has always worked, how Solaris, Illumos, FreeBSD, and systemd performs imports, and is how it is written in the man page (zpool(1M,8)): All pools in this cache are automatically imported when the system boots. Importantly, the cache contains important information for importing multipath devices, and helps control which pools get imported in more dynamic environments like SANs, which may have thousands of visible and constantly changing pools, which the ZFS_POOL_EXCEPTIONS variable is not equipped to handle. Verbatim imports prevent rogue pools from being automatically imported and mounted where they shouldn't be. The change also stops the service from exporting pools at shutdown. Exporting pools is only meant to be performed explicitly by the administrator of the system. The old behavior of searching and importing all visible pools is preserved and can be switched on by heeding the warning and toggling the ZPOOL_IMPORT_ALL_VISIBLE variable in /etc/default/zfs.

* Rename 'zed.service' to 'zfs-zed.service'Turbo Fredriksson2015-10-023-3/+6
| | | | | | | | | | | | | | | For consistency all systemd unit files and init scripts now share the same names. This prevents an issue where the zed is started twice on systems where both the systemd and sysv infrastructure is installed concurrently. For backward compatibility a 'zed' alias has been added. This allows the user to interact with the service using either the name 'zed' or 'zfs-zed'.
