NAME
dpm_modifypool - modify a disk pool definition SYNOPSIS
#include <sys/types.h> #include "dpm_api.h" int dpm_modifypool (struct dpm_pool *dpm_pool) DESCRIPTION
dpm_modifypool modifies a disk pool definition. dpm_pool contains the new pool definition. struct dpm_pool { char poolname[CA_MAXPOOLNAMELEN+1]; u_signed64 defsize; int gc_start_thresh; int gc_stop_thresh; int def_lifetime; int defpintime; int max_lifetime; int maxpintime; char fss_policy[CA_MAXPOLICYLEN+1]; char gc_policy[CA_MAXPOLICYLEN+1]; char mig_policy[CA_MAXPOLICYLEN+1]; char rs_policy[CA_MAXPOLICYLEN+1]; int nbgids; gid_t *gids; char ret_policy; char s_type; u_signed64 capacity; u_signed64 free; int nbelem; }; poolname specifies the disk pool name. defsize specifies the default amount of space reserved for a file (in bytes). If set to -1, the current value is unchanged. gc_start_thresh specifies the minimum free space in the pool. If the percentage of free space goes below this value, the garbage collector is started. If set to -1, the current value is unchanged. gc_stop_thresh specifies the percentage of free space in the pool above which the garbage collector is stopped. If set to -1, the current value is unchanged. def_lifetime specifies the default time a space or volatile file is kept in the system (in seconds). If set to -1, the current value is unchanged. defpintime specifies the default time a file is kept on a given disk (in seconds). If set to -1, the current value is unchanged. max_lifetime specifies the maximum time a space or volatile file is kept in the system (in seconds). If set to -1, the current value is unchanged. maxpintime specifies the maximum time a file is kept on a given disk (in seconds). If set to -1, the current value is unchanged. nbgids is the size of the array of group ids gids. If set to -1, the current set is unchanged. gids The disk pool is restricted to this set of gids unless the group gid is zero. ret_policy specifies the retention policy supported by the disk pool. It can be R (for Replica), O (for Output) or C (for Custodial). If set to 0, the current value is unchanged. s_type indicates the type of space supported in the disk pool. It can be V (for Volatile), D (for Durable), P (for Permanent) or - (to accept any type). If set to 0, the current value is unchanged. This function requires ADMIN privilege. RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately. ERRORS
ENOENT This pool does not exist. EACCES The caller does not have ADMIN privilege. EFAULT dpm_pool is a NULL pointer. EINVAL The length of poolname exceeds CA_MAXPOOLNAMELEN or the number of gids is too big. SENOSHOST Host unknown. SEINTERNAL Database error. SECOMERR Communication error. LCG

NAME
dpm_reservespace - reserve space SYNOPSIS
#include <sys/types.h> #include "dpm_api.h" int dpm_reservespace (const char s_type, const char *u_token, const char ret_policy, const char ac_latency, u_signed64 req_t_space, u_signed64 req_g_space, time_t req_lifetime, int nbgids, gid_t *req_gids, const char *poolname, char *actual_s_type, u_signed64 *actual_t_space, u_signed64 *actual_g_space, time_t *actual_lifetime, char *s_token) DESCRIPTION
dpm_reservespace reserves space. The input arguments are: s_type specifies the type of space requested. It can be V (for Volatile), D (for Durable), P (for Permanent) or - (for any). u_token specifies the user provided description associated with the request. This argument may be NULL. ret_policy specifies the retention policy requested. It can be R (for REPLICA), O (for OUTPUT) or C (for CUSTODIAL). ac_latency specifies the access latency requested. It can be O (for ONLINE) or N (for NEARLINE). req_t_space Total space requested in bytes. req_g_space Guaranteed space requested in bytes. req_lifetime specifies the requested space lifetime (in seconds) relative to the current time. nbgids is the size of the array of group ids req_gids. req_gids when zero, the space is reserved for the user if the requester has a proxy without VOMS extension or for the group if the requester has a proxy with VOMS extension. If not zero, the space is reserved for this set of group ids. If the caller does not belong to the group, it must have ADMIN privileges. poolname If not NULL, reserves the space in that disk pool. The output arguments are: actual_s_type Type of reserved space. actual_t_space Total space reserved in bytes (best effort). actual_g_space Guaranteed space reserved in bytes. actual_lifetime Lifetime of the reserved space (in seconds) relative to the current time. s_token Address of a buffer to receive the system allocated token. RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately. ERRORS
EACCES The caller does not belong to the group identified by req_gid and does not have ADMIN privileges. EFAULT nbgids is greater than 0 and req_gids is a NULL pointer. EINVAL The space type is invalid or the length of the user space token description is greater than 255, the space requested is not a positive value, the pool name is longer than CA_MAXPOOLNAMELEN or unknown or the number of gids is too big. SENOSHOST Host unknown. SEINTERNAL Database error. SECOMERR Communication error. LCG
