DPM_ADDPOOL(3) DPM Library Functions DPM_ADDPOOL(3)NAMEdpm_addpool - define a new disk poolSYNOPSIS#include <sys/types.h> #include "dpm_api.h" int dpm_addpool (struct dpm_pool *dpm_pool)DESCRIPTIONdpm_addpool defines a new disk pool. dpm_pool contains the 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). 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. Default is 0. gc_stop_thresh specifies the percentage of free space in the pool above which the garbage collector is stopped. Default is 0. def_lifetime specifies the default time a space or volatile file is kept in the system (in seconds). defpintime specifies the default time a file is kept on a given disk (in seconds). max_lifetime specifies the maximum time a space or volatile file is kept in the system (in seconds). maxpintime specifies the maximum time a file is kept on a given disk (in seconds). nbgids is the size of the array of group ids gids. 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). 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). This function requires ADMIN privilege.RETURN VALUEThis routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.ERRORSEACCES The caller does not have ADMIN privilege. EFAULT dpm_pool is a NULL pointer. EEXIST This pool exists already. ENOMEM Memory could not be allocated for storing the pool definition. 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$Date: 2011-05-23 14:22:57 +0200 (Mon, 23 May 2011) $ DPM_ADDPOOL(3)
