DESCRIPTION

lcg_rep copies a file from one Storage Element to another Storage Element and registers it in the LRC or the LFC.

src_file

specifies the source file name: the protocol can be LFN, GUID or SURL. An SURL scheme can be sfn: for a classical SE or srm:.

dest_file

specifies the destination. It can be the Storage Element fully qualified hostname or an SURL. In the latter case, the scheme can be sfn: for a classical SE or srm:. If only the fully qualified hostname is given, a filename is generated in the same format as with the Replica Manager.

relative_path

specifies the path relative to the SARoot for the given VO.

nbstreams

specifies the number of parallel streams (default 1).

defaulttype

specifies the default SE type you want to use. Possible values are TYPE_NONE, TYPE_SE, TYPE_SRM, TYPE_SRMv2, for respectively no default type, classic SE, SRMv1, and SRMv2. But if according to the BDII the default type is not available for this SE, it will use another type.

srctype

specifies the SE type you want to use for the source file. Possible values are TYPE_NONE, TYPE_SE, TYPE_SRM, TYPE_SRMv2, for respectively no type, classic SE, SRMv1, and SRMv2. But if according to the BDII the default type is not available for this SE, it will fail.

dsttype

specifies the SE type you want to use for the destination file. Possible values are TYPE_NONE, TYPE_SE, TYPE_SRM, TYPE_SRMv2, for respectively no type, classic SE, SRMv1, and SRMv2. But if according to the BDII the default type is not available for this SE, it will fail.

nobdii

If set to a non-zero value, it means that you don't want to make BDII calls to get SE type. So, you must provide the type of the SE for srm: arguments, and full endpoint in SURLs. For SE type, defaulttype can be used (it will be used for both source and destination).

timeout

specifies the value of timeout (default 0).

verbose

Verbose level. Here are the possible levels:

0: Only critical errors are displayed on stderr or put into errbuf if not null.
1: Warnings are displayed on stderr as well as critical errors.
2: Debug information is displayed as well as warnings and critical errors.

vo

specifies the Virtual Organization the user belongs to. If it is not specified, the environment variable LCG_GFAL_VO will be used.

conf_file

This argument is currently ignored.

insecure

This argument is currently ignored. The access to the Replica Catalog or the LFC is done according to the endpoints published in MDS while the copy is always done in secure mode.

cksmtype

is the checksum type (algorithm) to use. Possible values are:

GFAL_CKSM_NONE: No checksum verification
GFAL_CKSM_CRC32: CRC32 algorithm will be used
GFAL_CKSM_ADLER32: Adler32 algorithm will be used
GFAL_CKSM_MD5: MD5 algorithm will be used
GFAL_CKSM_SHA1: SHA-1 algorithm will be used

errbuf

specifies a buffer of size errbufsz to receive detailed error messages. If this pointer is NULL, the message goes to stderr. The pointer should not be NULL if the application is a daemon or is multi-threaded.

src_spacetokendesc

specifies the space token to use with src_file. Can be NULL.

dest_spacetokendesc

specifies the space token to use with dest_file. Can be NULL.

actual_surl

is a pointer to a char* variable. If not set to NULL, the actual SURL of the new replica will be stored in this variable.

NOTE

The environment variable LCG_GFAL_INFOSYS must point to the BDII, unless nobdii is set to a non-zero value. To use the RLS as catalog instead of the LFC, the environment variable LCG_CATALOG_TYPE must explicitely be set to "edg". By default, it is set to "lfc".

RETURN VALUE

This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, errno is set appropriately.

ERRORS

ENOENT: The named file does not exist.
EACCES: Permission denied.
EFAULT: src_file, dest_file or vo is an invalid pointer.
EINVAL: src_file or dest_file has an invalid syntax.
ECOMM: Communication error.
ENAMETOOLONG: vo is too long.
EPROTONOSUPPORT: Access method not supported.
