NAME¶

lfc_listreplicax - list replica entries for a given pool/server/filesystem

SYNOPSIS¶

#include <sys/types.h> #include "lfc_api.h" struct lfc_filereplica *lfc_listreplicax (const char *poolname, const char *server, const char *fs, int flags, lfc_list *listp)

DESCRIPTION¶

lfc_listreplicax lists replica entries for a given pool/server/filesystem. This routine returns a pointer to a structure containing the current replica entry.

struct lfc_filereplica {
	u_signed64	fileid;
	u_signed64	nbaccesses;
	time_t		atime;		/* last access to replica */
	time_t		ptime;		/* replica pin time */
	char		status;
	char		f_type;		/* 'V' for Volatile, 'P' for Permanent */
	char		poolname[CA_MAXPOOLNAMELEN+1];
	char		host[CA_MAXHOSTNAMELEN+1];
	char		fs[80];
	char		sfn[CA_MAXSFNLEN+1];
};

poolname

specifies the disk pool (only meaningful for the DPM).

server

specifies the Storage Element or disk server hostname.

fs

specifies the file system (only meaningful for the DPM).

flags

may be one of the following constant:

RETURN VALUE¶

This routine returns a pointer to a structure containing the current replica entry if the operation was successful or NULL if all entries have been returned or if the operation failed. In the latter case, serrno is set appropriately.

EXAMPLES¶

A C program listing the files residing on a given server could look like:

	int flags;
	lfc_list list;
	struct lfc_filereplica *lp;

	flags = CNS_LIST_BEGIN;
	while ((lp = lfc_listreplicax (NULL, server, NULL, flags, &list))) {
		flags = CNS_LIST_CONTINUE;
		/* process the entry */
		.....
	}
	(void) lfc_listreplicax (NULL, server, NULL, CNS_LIST_END, &list);

ERRORS¶

ENOMEM

Memory could not be allocated for the output buffer.

EFAULT

poolname, server and fs are NULL pointers or listp is a NULL pointer.

EINVAL

The length of poolname exceeds CA_MAXPOOLNAMELEN or the length of server exceeds CA_MAXHOSTNAMELEN or the length of fs exceeds 79.

SENOSHOST

Host unknown.

SENOSSERV

Service unknown.

SECOMERR

Communication error.

ENSNACT

Name server is not running or is being shutdown.
