@ -19,15 +19,43 @@ Mount Options
When mounting an XFS filesystem, the following options are accepted.
biosize=size
Sets the preferred buffered I/O size (default size is 64K).
"size" must be expressed as the logarithm (base2) of the
desired I/O size.
Valid values for this option are 14 through 16, inclusive
(i.e. 16K, 32K, and 64K bytes). On machines with a 4K
pagesize, 13 (8K bytes) is also a valid size.
The preferred buffered I/O size can also be altered on an
individual file basis using the ioctl(2) system call.
allocsize=size
Sets the buffered I/O end-of-file preallocation size when
doing delayed allocation writeout (default size is 64KiB).
Valid values for this option are page size (typically 4KiB)
through to 1GiB, inclusive, in power-of-2 increments.
attr2/noattr2
The options enable/disable (default is disabled for backward
compatibility on-disk) an "opportunistic" improvement to be
made in the way inline extended attributes are stored on-disk.
When the new form is used for the first time (by setting or
removing extended attributes) the on-disk superblock feature
bit field will be updated to reflect this format being in use.
barrier
Enables the use of block layer write barriers for writes into
the journal and unwritten extent conversion. This allows for
drive level write caching to be enabled, for devices that
support write barriers.
dmapi
Enable the DMAPI (Data Management API) event callouts.
Use with the "mtpt" option.
grpid/bsdgroups and nogrpid/sysvgroups
These options define what group ID a newly created file gets.
When grpid is set, it takes the group ID of the directory in
which it is created; otherwise (the default) it takes the fsgid
of the current process, unless the directory has the setgid bit
set, in which case it takes the gid from the parent directory,
and also gets the setgid bit set if it is a directory itself.
ihashsize=value
Sets the number of hash buckets available for hashing the
in-memory inodes of the specified mount point. If a value
of zero is used, the value selected by the default algorithm
will be displayed in /proc/mounts.
ikeep/noikeep
When inode clusters are emptied of inodes, keep them around

and is still the default for now. Using the noikeep option,
inode clusters are returned to the free space pool.
inode64
Indicates that XFS is allowed to create inodes at any location
in the filesystem, including those which will result in inode
numbers occupying more than 32 bits of significance. This is
provided for backwards compatibility, but causes problems for
backup applications that cannot handle large inode numbers.
largeio/nolargeio
If "nolargeio" is specified, the optimal I/O reported in
st_blksize by stat(2) will be as small as possible to allow user
applications to avoid inefficient read/modify/write I/O.
If "largeio" specified, a filesystem that has a "swidth" specified
will return the "swidth" value (in bytes) in st_blksize. If the
filesystem does not have a "swidth" specified but does specify
an "allocsize" then "allocsize" (in bytes) will be returned
instead.
If neither of these two options are specified, then filesystem
will behave as if "nolargeio" was specified.
logbufs=value
Set the number of in-memory log buffers. Valid numbers range
from 2-8 inclusive.
The default value is 8 buffers for filesystems with a
blocksize of 64K, 4 buffers for filesystems with a blocksize
of 32K, 3 buffers for filesystems with a blocksize of 16K
blocksize of 64KiB, 4 buffers for filesystems with a blocksize
of 32KiB, 3 buffers for filesystems with a blocksize of 16KiB
and 2 buffers for all other configurations. Increasing the
number of buffers may increase performance on some workloads
at the cost of the memory used for the additional log buffers
@ -49,10 +96,10 @@ When mounting an XFS filesystem, the following options are accepted.
logbsize=value
Set the size of each in-memory log buffer.
Size may be specified in bytes, or in kilobytes with a "k" suffix.
Valid sizes for version 1 and version 2 logs are 16384 (16k) and
32768 (32k). Valid sizes for version 2 logs also include
