33 # By default, a verbatim import of all pools is performed at boot based on the
34 # contents of the default zpool cache file. The contents of the cache are
35 # managed automatically by the 'zpool import' and 'zpool export' commands.
37 # By setting this to 'yes', the system will instead search all devices for
38 # pools and attempt to import them all at boot, even those that have been
39 # exported. Under this mode, the search path can be controlled by the
40 # ZPOOL_IMPORT_PATH variable and a list of pools that should not be imported
41 # can be listed in the ZFS_POOL_EXCEPTIONS variable.
43 # Note that importing all visible pools may include pools that you don't
44 # expect, such as those on removable devices and SANs, and those pools may
45 # proceed to mount themselves in places you do not want them to. The results
46 # can be unpredictable and possibly dangerous. Only enable this option if you
47 # understand this risk and have complete physical control over your system and
48 # SAN to prevent the insertion of malicious pools.

51 # Specify specific path(s) to look for device nodes and/or links for the
52 # pool import(s). See zpool(8) for more information about this variable.
53 # It supersedes the old USE_DISK_BY_ID which indicated that it would only
54 # try '/dev/disk/by-id'.

72 # Any additional option to the 'zfs import' commandline?
73 # Include '-o' for each option wanted.
74 # You don't need to put '-f' in here, unless you want it ALL the time.
75 # Using the option 'zfsforce=1' on the grub/kernel command line will
76 # do the same, but on a case-to-case basis.
79 # Full path to the ZFS cache file?
80 # See "cachefile" in zpool(8).
81 # The default is "@sysconfdir@/zfs/zpool.cache".
82 #ZPOOL_CACHE="@sysconfdir@/zfs/zpool.cache"
84 # Setting ZPOOL_CACHE to an empty string ('') AND setting ZPOOL_IMPORT_OPTS to
85 # "-c @sysconfdir@/zfs/zpool.cache" will _enforce_ the use of a cache file.
86 # This is needed in some cases (extreme amounts of VDEVs, multipath etc).
87 # Generally, the use of a cache file is usually not recommended on Linux
88 # because it sometimes is more trouble than it's worth (laptops with external
89 # devices or when/if device nodes changes names).
