xfs_admin(8) System Manager's Manual xfs_admin(8)
NAME
xfs_admin - change parameters of an XFS filesystem
SYNOPSIS
xfs_admin [ -eflu ] [ -c 0|1 ] [ -L label ] [ -U uuid ] device
DESCRIPTION
xfs_admin uses the xfs_db(8) command to modify various parameters of a filesystem.
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.
OPTIONS
-e Enables unwritten extent support on a filesystem that does not already have this enabled (for legacy filesystems, it can't be dis-
abled anymore at mkfs time).
-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 log buffers).
-l Print the current filesystem label.
-u Print the current filesystem UUID (Universally Unique IDentifier).
-c 0|1 Enable (1) or disable (0) lazy-counters in the filesystem. This operation may take quite a bit of time on large filesystems as the
entire filesystem needs to be scanned when this option is changed.
With lazy-counters enabled, the superblock is not modified or logged on every change of the free-space and inode counters. Instead,
enough information is kept in other parts of the filesystem to be able to maintain the counter values without needing to keep them
in the superblock. This gives significant improvements in performance on some configurations and metadata intensive workloads.
-L label
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.
-U uuid
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.
