dpm_addfs - add a filesystem to a disk pool
#include <sys/types.h> #include "dpm_api.h" int dpm_addfs (char *poolname, char *server, char *fs, int status, int weight)
dpm_addfs adds a filesystem to a disk pool. poolname specifies the disk pool name previously defined using dpm_addpool. server specifies the host name of the disk server where this filesystem is mounted. fs specifies the mount point of the dedicated filesystem. status Initial status of this filesystem. It can be set to 0 or FS_DISABLED or FS_RDONLY. weight specifies the weight of the filesystem. This is used during the filesystem selection. The value must be positive. A negative value will tell the server to allocate the default weight value (1). It is recommended to use a value lower than 10. This function requires ADMIN privilege.
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
ENOENT Filesystem does not exist. EACCES The caller does not have ADMIN privilege. EFAULT poolname, server or fs is a NULL pointer. EEXIST this filesystem is already part of a pool. ENOMEM Memory could not be allocated for storing the filesystem definition. EINVAL The pool is unknown or 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. SEINTERNAL Database error. SECOMERR Communication error.
