DESCRIPTION

16       to use the same API for ext2/ext3/ext4, ReiserFS and XFS filesystem.

OPTIONS

19       -h --help
20              — print help message
21
22       -v --verbose
23              — be more verbose
24
25       -e --ext-offline
26              — unmount ext2/ext3/ext4 filesystem before doing resize
27
28       -f --force
29              — bypass some sanity checks
30
31       -n --dry-run
32              — print commands without running them
33
34       -y --yes
35              — answer "yes" at any prompts
36
37       new_size
38              — Absolute number of filesystem blocks to be in the  filesystem,
39              or  an  absolute  size  using  a suffix (in powers of 1024).  If
40              new_size is not supplied, the whole device is used.

DIAGNOSTICS

44       On successful completion, the status code is 0.  A  status  code  of  2
45       indicates  the operation was interrupted by the user.  A status code of
46       3 indicates the  requested  check  operation  could  not  be  performed
47       because  the filesystem is mounted and does not support an online fsck.
48       A status code of 1 is used for other failures.

EXAMPLES

52       "fsadm -e -y resize /dev/vg/test 1000M" tries to resize the  filesystem
53       on logical volume /dev/vg/test. If /dev/vg/test contains ext2/ext3/ext4
54       filesystem it will be unmounted prior the resize.  All [y|n]  questions
55       will be answered 'y'.

ENVIRONMENT VARIABLES
