Installation guide

scan = [ "/dev/mapper" ]

# If several entries in the scanned directories correspond to the

# same block device and the tools need to display a name for device,

# all the pathnames are matched against each item in the following

# list of regular expressions in turn and the first match is used.

preferred_names = [ ]

# preferred_names = [ "^/dev/mpath/", "^/dev/[hs]d" ]

# A filter that tells LVM2 to only use a restricted set of devices.

# The filter consists of an array of regular expressions. These

# expressions can be delimited by a character of your choice, and

# prefixed with either an 'a' (for accept) or 'r' (for reject).

# The first expression found to match a device name determines if

# the device will be accepted or rejected (ignored). Devices that

# don't match any patterns are accepted.

# Be careful if there there are symbolic links or multiple filesystem

# entries for the same device as each name is verifyed separately

against

# the list of patterns. The effect is that if any name matches any 'a'

# pattern, the device is accepted; otherwise if any name matches any

'r'

# pattern it is rejected; otherwise it is accepted.

# Don't have more than one filter line active at once: only one gets

used.

# Run vgscan after you change this parameter to ensure that

# the cache file gets regenerated (see below).

# If it doesn't do what you expect, verify the output of 'vgscan

-vvvv'.

# By default we accept every block device:

filter = [ "a/.*/" ]

# Exclude the cdrom drive

# filter = [ "r|/dev/cdrom|" ]

# When testing I like to work with just loopback devices:

# filter = [ "a/loop/", "r/.*/" ]

# Or maybe all loops and IDE drives except hdc:

# filter =[ "a|loop|", "r|/dev/hdc|", "a|/dev/ide|", "r|.*|" ]

# Use anchors if you want to be really specific

# filter = [ "a|^/dev/hda8$|", "r/.*/" ]

# The results of the filtering are cached on disk to avoid

# rescanning dud devices (which can take a very long time).

# By default this cache is stored in the /etc/lvm/cache directory

# in a file called '.cache'.
