Building
|
|
----------------------
|
|
|
|
The DAOS library must be installed on the system.
|
|
|
|
./bootstrap
|
|
./configure --prefix=iorInstallDir --with-daos=DIR
|
|
|
|
The DFS (DAOS File System) driver creates an encapsulated namespace and emulates
|
|
the POSIX driver using the DFS API directly on top of DAOS. The DFS driver works
|
|
with both IOR and mdtest.
|
|
|
|
Running
|
|
---------------------
|
|
|
|
ior -a DFS [ior_options] [dfs_options]
|
|
mdtest -a DFS [mdtest_options] [dfs_options]
|
|
|
|
Required Options:
|
|
--dfs.pool <pool_uuid>: pool uuid to connect to (has to be created beforehand)
|
|
--dfs.svcl <pool_svcl>: pool svcl list (: separated)
|
|
--dfs.cont <co_uuid>: container uuid that will hold the encapsulated namespace
|
|
|
|
Optional Options:
|
|
--dfs.group <group_name>: group name of servers with the pool (default: daos_server)
|
|
--dfs.chunk_size <chunk_size>: Chunk size of the files (default: 1MiB)
|
|
--dfs.destroy: flag to destroy the container on finalize (default: no)
|
|
--dfs.oclass <object_class>: specific object class for files (default: SX)
|
|
--dfs.dir_oclass <object_class>: specific object class for directories (default: SX)
|
|
--dfs.prefix <path>: absolute path to account for DFS files/dirs before the cont root
|
|
|
|
If prefix is not set, in the IOR options, the file name should be specified on
|
|
the root dir directly since ior does not create directories and the DFS
|
|
container representing the encapsulated namespace is not the same as the system
|
|
namespace the user is executing from.
|
|
|
|
Examples that should work include:
|
|
- "ior -a DFS -w -W -o /test1 --dfs.pool <pool_uuid> --dfs.svcl <svc_ranks> --dfs.cont <co_uuid>"
|
|
- "ior -a DFS -w -W -r -R -o /test2 -b 1g -t 4m -C --dfs.pool <pool_uuid> --dfs.svcl <svc_ranks> --dfs.cont <co_uuid>"
|
|
- "ior -a DFS -w -r -o /test3 -b 8g -t 1m -C --dfs.pool <pool_uuid> --dfs.svcl <svc_ranks> --dfs.cont <co_uuid>"
|
|
|
|
Running mdtest, the user needs to specify a directory with -d where the test
|
|
tree will be created (set '/' if writing to the root of the DFS container). Some
|
|
examples:
|
|
- "mdtest -a DFS -n 100 -F -D -d / --dfs.pool <pool_uuid> --dfs.svcl <svc_ranks> --dfs.cont <co_uuid>"
|
|
- "mdtest -a DFS -n 1000 -F -C -d / --dfs.pool <pool_uuid> --dfs.svcl <svc_ranks> --dfs.cont <co_uuid>"
|
|
- "mdtest -a DFS -I 10 -z 5 -b 2 -L -d / --dfs.pool <pool_uuid> --dfs.svcl <svc_ranks> --dfs.cont <co_uuid>"
