lvchange(1M) lvchange(1M)

"forever". NOTE: The actual duration of the request may exceed the

speciﬁed IO_timeout value when the underlying physical volume(s) have

timeouts which either exceed this IO_timeout value or are not integer mul-

tiples of this value.

EXTERNAL INFLUENCES

Environment Variables

LANG determines the language in which messages are displayed.

If LANG is not speciﬁed or is null, it defaults to "C" (see lang(5)).

If any internationalization variable contains an invalid setting, all internationalization variables default to

"C" (see environ(5)).

EXAMPLES

Change the permission of a logical volume to read-only:

lvchange -p r /dev/vg01/lvol3

Change the allocation policy of a logical volume to nonstrict:

lvchange -s n /dev/vg01/lvol7

Turn the mirror write cache off on a logical volume:

lvchange -M n /dev/vg01/lvol1

Change the IO timeout value of a logical volume to 1 minute (60 seconds):

lvchange -t 60 /dev/vg01/lvol1

WARNINGS

For root, swap or dump logical volumes, the allocation policy is always contiguous. This attribute cannot be

changed with lvchange.
