|
.SH DESCRIPTION
|
||
|
|
.B thin_metadata_size
|
||
|
|
calculates the size of the thin provisioning metadata based on the block size
|
||
|
|
of the thin provisioned devices, the size of the thin provisioning pool and
|
||
|
|
the maximum number of all thin prisioned devices and snapshots.
|
||
|
|
|
||
|
|
.IP "\fB\-b, \-\-block-size\fP \fIBLOCKSIZE[bskKmMgGtTpPeEzZyY]\fP"
|
||
|
|
Block size of thin provisioned devices in units of bytes,sectors,kilobytes,kibibytes,... respectively.
|
||
|
|
Default is in sectors without a block size unit specifier.
|
||
|
|
|
||
|
|
.IP "\fB\-s, \-\-pool-size\fP \fIPOOLSIZE[bskKmMgGtTpPeEzZyY]\fP"
|
||
|
|
Thin provisioning pool size in units of bytes,sectors,kilobytes,kibibytes,... respectively.
|
||
|
|
Default is in sectors without a pool size unit specifier.
|
||
|
|
|
||
|
|
.IP "\fB\-m, \-\-max-thins\fP \fI#[bskKmMgGtTpPeEzZyY]\fP"
|
||
|
|
Maximum sum of all thin provisioned devices and snapshots.
|
||
|
|
Unit identifier supported to allow for convenient entry of large quantities, eg. 1000000 = 1M.
|
||
|
|
Default is absolut quantity without a number unit specifier.
|
||
|
|
|
||
|
|
.IP "\fB\-u, \-\-unit\fP \fI[bskKmMgGtTpPeEzZyY]\fP"
|
||
|
|
Output unit specifier in units of bytes,sectors,kilobytes,kibibytes,... respectively.
|
||
|
|
Default is in sectors without an output unit specifier.
|
||
|
|
|
||
|
|
.IP "\fB\-n[u], \-\-numeric-only[=unit]\fP"
|
||
|
|
Limit output to just the size number with the optional unit specifier character.
|
||
|
|
|
||
|
|
.IP "\fB\-h, \-\-help\fP"
|
||
|
|
Print help and exit.

.SH EXAMPLES
|
||
|
|
Calculates the thin privisioning metadata device size for block size 64 kilobytes,
|
||
|
|
pool size 1 terabytes and maximum number of thin provisioned devices and snapshots of 1000
|
||
|
|
in units of sectors with long output.
|
||
|
|
.sp
|
||
|
|
.B thin_metadata_size -b64k -s1t -m1000
|
||
|
|
|
||
|
|
Or (using the long options inmstead) for block size 1 gigabyte, pool size 1 petabytes and maximum number of thin provisioned devices
|
||
|
|
and snapshots of 1 million in units of gigabytes with numeric only output.
|
||
|
|

.B thin_metadata_size --block-size=1g --pool-size=1p --max-thins=1M --unit=g --numeric-only
|
||
|
|
|
||
|
|
Same as before (1g,1p,1M,numeric-only) but with unit specifier character appended.
