* initramfs: Honor canmount=offRichard Laager2017-11-281-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | The initramfs script was not honoring canmount=off. With this change, it does. If the administrator has asked that a filesystem not be mounted, that should be honored. As an exception, the initramfs script ignores canmount=off on the rootfs. The rootfs should not have canmount=off set either. However, mounting it anyway seems harmless because it is being asked for explicitly. The point of this exception is to avoid the risk of breaking existing systems, just in case someone has canmount=off set on their rootfs. The initramfs still mounts filesystems with canmount=noauto. This is necessary because it is typical to set that on the rootfs so that it can be cloned. Without canmount=noauto, the clones' duplicate mountpoints would conflict.

* initramfs: Honor mountpoint=none/legacyRichard Laager2017-11-281-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For filesystems that are children of the rootfs, when mountpoint=none or mountpoint=legacy, the initrafms script would assume a mountpoint based on the dataset path. Given that the rootfs should have mountpoint=/ and mountpoint inheritance is is the default behavior of ZFS, this behavior seems unnecessary. In any event, it turns mountpoint=none into a no-op. That removes this option from the administrator, and if someone uses it, it does not work as expected. Worse yet, if the mountpoint directory does not exist (which is the typical case for mountpoint=none), the mounting and thus the boot process will fail. For the case of mountpoint=legacy, the assumed mountpoint may not be the correct value set in /etc/fstab. This change makes the initramfs script not mount the filesystem in either case. For mountpoint=none, this means we are correctly honoring the setting. For mountpoint=legacy, there are two scenarios: If canmount=on, the filesystem will be mounted by the normal mechanisms later in the boot process. If canmount=noauto, the filesystem will not be mounted at all, unless the administrator has done something special. If they're not doing something special and they want it mounted by the initramfs, they can simply not set mountpoint=legacy.

* Fix some minor issues with the SYSV init and initramfs scripts.Turbo Fredriksson2015-07-241-2/+2
| | | | | | | | | | | | | | | | | | | | | This is some minor fixes to commits 2cac7f5f11756663525a5d4604d9f0a3202d4024 and 2a34db1bdbcecf5019c4a59f2a44c92fe82010f2. * Make sure to alien'ate the new initramfs rpm package as well! The rpm package is build correctly, but alien isn't run on it to create the deb. * Before copying file from COPY_FILE_LIST, make sure the DESTDIR/dir exists. * Include /lib/udev/vdev_id file in the initrd. * Because the initrd needs to use '/sbin/modprobe' instead of 'modprobe', we need to use this in load_module() as well. * Make sure that load_module() can be used more globaly, instead of calling '/sbin/modprobe' all over the place. * Make sure that check_module_loaded() have a parameter - module to check.

* Initramfs scripts for ZoL.Turbo Fredriksson2015-07-081-0/+962
* Supports booting of a ZFS snapshot. Do this by cloning the snapshot into a dataset. If this, the resulting dataset, already exists, destroy it. Then mount it on root. * If snapshot does not exist, use base dataset (the part before '@') as boot filesystem instead. * If no snapshot is specified on the 'root=' kernel command line, but there is an '@', then get a list of snapshots below that filesystem and ask the user which to use. * Clone with 'mountpoint=none' and 'canmount=noauto' - we mount manually and explicitly. * For sub-filesystems, that doesn't have a mountpoint property set, we use the 'org.zol:mountpoint' to keep track of it's mountpoint. * Allow rollback of snapshots instead of clone it and boot from the clone. * Allow mounting a root- and subfs with mountpoint=legacy set * Allow mounting a filesystem which is using nativ encryption. * Support all currently used kernel command line arguments All the different distributions have their own standard on what to specify on the kernel command line to boot of a ZFS filesystem. * Extra options: * zfsdebug=(on,yes,1) Show extra debugging information * zfsforce=(on,yes,1) Force import the pool * rollback=(on,yes,1) Rollback (instead of clone) the snapshot * Only try to import pool if it haven't already been imported * This will negate the need to force import a pool that have not been exported cleanly. * Support exclusion of pools to import by setting ZFS_POOL_EXCEPTIONS in /etc/default/zfs. * Support additional configuration variable ZFS_INITRD_ADDITIONAL_DATASETS to mount additional filesystems not located under your root dataset. * Include /etc/modprobe.d/{zfs,spl}.conf in the initrd if it/they exist. * Include the udev rule to use by-vdev for pool imports. * Include the /etc/default/zfs file to the initrd. * Only try /dev/disk/by-* in the initrd if USE_DISK_BY_ID is set. * Use /dev/disk/by-vdev before anything. * Add /dev as a last ditch attempt. * Fallback to using the cache file if that exist if nothing else worked. * Use /sbin/modprobe instead of built-in (BusyBox) modprobe. This gets rid of the message "modprobe: can't load module zcommon". Thanx to pcoultha for finding this.
