user accounting with limit enforcement disabled. quotaon(8)
contains some examples of frequently used procedures.
- o Turning on quotas on the root filesystem is slightly different from
- the above. quotaon(8) must be used on the root XFS filesystem
- first; quotas will be turned on the next time the system is
- rebooted. It is useful to use repquota(8) with the -v option to
- monitor the effect of quotaon/off at various stages.
+ o Turning on quotas on the root filesystem is slightly different
+ from the above. In more recent versions of XFS, the quota mount
+ flags must be passed in with the "rootflags=" boot parameter.
+ In older versions of XFS and (quota-tools) quotaon(8) must be
+ used on the root XFS filesystem first; and quotas will be turned
+ on the next time the system is rebooted.
+
+ o It is useful to use repquota(8) with the -v option to monitor
+ the XFS quota state at various stages.
o quotacheck(8) has no effect on XFS filesystems. The first time
quota accounting is turned on, XFS does an automatic quotacheck
EXAMPLES
->>> Enabling quota enforcement on a non-root XFS filesystem
+>>> Enabling quota enforcement on an XFS filesystem
[root@troppo]# echo /dev/hdb10 /mnt/xqm xfs rw,usrquota 0 0 >>/etc/fstab
[root@troppo]# mount /mnt/xqm
A filesystem that has used user quota on IRIX, however, can be migrated
to Linux, and vice-versa, as the ondisk format is shared between both
versions of XFS (and Linux/XFS is "endian clean"). Group quota support
-is planned for a future release of IRIX, and the same level of ondisk
-compatibility will be available as for user quota, once this work has
-been completed.
+has been implemented only in more recent versions of IRIX 6.5f, and the
+same level of ondisk compatibility is now available as for user quota.

.I mkfs.xfs
.BR log= ,
or in bytes with
.BR size= .
-The default value is 4096 bytes (4 KB) on systems with a 4KB pagesize.
-The minimum value for block size is 512; the maximum is 65536 (64 KB).
+The default value is 4096 bytes (4 KB), the minimum is 512, and the
+maximum is 65536 (64 KB).
XFS on Linux currently only supports pagesize or smaller blocks.
.TP
.B \-d
filesystem should occupy
less space than the size of the partition or logical volume containing the section.
.TP
-.B \-C
-Disable overlapping partition/volume checks.
-.IP
-By default \f2mkfs.xfs\f1 checks to see if the destination partition or logical
-volume overlaps any mounted or reserved partitions in the system. If an
-overlap or mount conflict is found, the user will be notified and prevented
-from potentially corrupting the existing data. For systems with
-a large number of disks, this additional checking may add noticable overhead
-to the command's execution time. For situations where command performance is
-necessary, this switch may be used to disable the safeguards. Due to the
-potential for user-error causing corrupted filesystems or other on-disk
-data corruption, we strongly discourage use of this switch in normal operation.
-.TP
\f3\-L\f1 \f2label\f1
Set the filesystem label.
XFS filesystem labels can be at most 12 characters long; if
and
.IR xfs_admin (8)
manual entries for additional information.
+.TP
+.B \-N
+Causes the file system parameters to be printed out without really
+creating the file system.
