# Configuration option devices/filter. # Limit the block devices that are used by LVM commands. # This is a list of regular expressions used to accept or reject block # device path names. Each regex is delimited by a vertical bar '|' # (or any character) and is preceded by 'a' to accept the path, or # by 'r' to reject the path. The first regex in the list to match the # path is used, producing the 'a' or 'r' result for the device. # When multiple path names exist for a block device, if any path name # matches an 'a' pattern before an 'r' pattern, then the device is # accepted. If all the path names match an 'r' pattern first, then the # device is rejected. Unmatching path names do not affect the accept # or reject decision. If no path names for a device match a pattern, # then the device is accepted. Be careful mixing 'a' and 'r' patterns, # as the combination might produce unexpected results (test changes.) # Run vgscan after changing the filter to regenerate the cache. # See the use_lvmetad comment for a special case regarding filters. # # Example # Accept every block device: # filter = [ "a|.*/|" ] # Reject the cdrom drive: # filter = [ "r|/dev/cdrom|" ] # Work with just loopback devices, e.g. for testing: # filter = [ "a|loop|", "r|.*|" ] # Accept all loop devices and ide drives except hdc: # filter = [ "a|loop|", "r|/dev/hdc|", "a|/dev/ide|", "r|.*|" ] # Use anchors to be very specific: # filter = [ "a|^/dev/hda8$|", "r|.*/|" ] # # This configuration option has an automatic default value. # filter = [ "a|.*/|" ] filter = ["a/sda/","a/mapper/3PAR8400_DEV_LUN26p1/","r/.*/"] #filter = ["a/sda/","r/.*/"]
# Configuration option devices/global_filter. # Limit the block devices that are used by LVM system components. # Because devices/filter may be overridden from the command line, it is # not suitable for system-wide device filtering, e.g. udev and lvmetad. # Use global_filter to hide devices from these LVM system components. # The syntax is the same as devices/filter. Devices rejected by # global_filter are not opened by LVM. # This configuration option has an automatic default value. # global_filter = [ "a|.*/|" ] global_filter = ["a/sda/","a/mapper/3PAR8400_DEV_LUN26p1/","r/.*/"]
