create a persistent memory pool
Synopsis
$ pmempool create [<options>] [<type>] <file>
Description
The pmempool invoked with create command creates a pool file of specified type.
The only valid pool types is: obj which stands for pmemobj pool. By default the pool file is created with minimum allowed size for specified pool type. The minimum sizes for obj pool type is PMEMOBJ_MIN_POOL. See libpmemobj(7) for details.
In order to set custom size of pool use -s option, or use -M option to create a pool of maximum available size on underlying file system.
The size argument may be passed in format that permits only the upper-case character for byte - B as specified in IEC 80000-13, IEEE 1541 and the Metric Interchange Format. Standards accept SI units with obligatory B - kB, MB, GB, ... which means multiplier by 1000 and IEC units with optional “iB” - KiB, MiB, GiB, ..., K, M, G, ... - which means multiplier by 1024.
Available options
-s, --size <size>
Size of pool file.
-M, --max-size
Set size of pool to available space of underlying file system.
-m, --mode <octal>
Set permissions to (the default is 0664) when creating the files. If the file already exist the permissions are not changed.
-i, --inherit <file>
Create a new pool of the same size and other properties as <file>.
-b, --clear-bad-blocks
Clear bad blocks in existing files.
-f, --force
Remove the pool before creating.
-v, --verbose
Increase verbosity level.
-h, --help
Display help message and exit.
-l, --layout <layout>
Layout name of the pmemobj pool. By default when creating a pmem obj pool, the layout name provided to the libpmemobj library is an empty string. Please refer to libpmemobj(7) for details.
Example
$ pmempool create obj pool.obj
Create a obj pool file of minimum allowed size
$ pmempool create obj -M pool.obj
Create a obj pool file of maximum allowed size
$ pmempool create --layout my_layout obj pool.obj
Create an obj pool file of minimum allowed size and layout “my_layout”
$ pmempool create --inherit=pool.obj new_pool.obj
Create a pool file based on pool.obj file
