xfs_admin - change parameters of an XFS filesystem
xfs_admin [ -eflu ] [ -L label ] [ -U uuid ] device
xfs_admin uses the xfs_db(8) command to modify various parameters of a
Devices that are mounted cannot be modified. Administrators must
unmount filesystems before xfs_admin or xfs_db(8) can convert
parameters. A number of parameters of a mounted filesystem can be
examined and modified using the xfs_growfs(8) command.
-e Enables unwritten extent support on a filesystem that does not
already have this enabled.
-f Specifies that the filesystem image to be processed is stored in
a regular file at device (see the mkfs.xfs -d file option).
-j Enables version 2 log format (journal format supporting larger
-l Print the current filesystem label.
-u Print the current filesystem UUID (Universally Unique
Set the filesystem label to label. XFS filesystem labels can be
at most 12 characters long; if label is longer than 12
characters, xfs_admin will truncate it and print a warning
message. The filesystem label can be cleared using the special
"--" value for label.
Set the UUID of the filesystem to uuid. A sample UUID looks
like this: "c1b9d5a2-f162-11cf-9ece-0020afc76f16". The uuid may
also be nil, which will set the filesystem UUID to the null
UUID. The uuid may also be generate, which will generate a new
UUID for the filesystem.
The mount(8) manual entry describes how to mount a filesystem using its
label or UUID, rather than its block special device name.
