* Make sure that POOL_IMPORTED is set, unset and checked where appropriate.Turbo Fredriksson2015-07-281-10/+17
| | | | | | | | | | | | | * If it's unset in find_rootfs(), no pool is imported so no point in looking for a rootfs. * If find_rootfs() couldn't find a rootfs, the pool is exported. Remember to unset POOL_IMPORTED after doing so. * Set POOL_IMPORTED if/when a pool have been imported in import_pool(). * Improve backup import (the one using cache file).

* 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.
