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-modifypool - modify a disk pool definition SYNOPSIS
dpm-modifypool --poolname pool_name [ --def_filesize defsize ] [ --def_lifetime def_lifetime ] [ --def_pintime defpintime ] [ --gc_start_thresh perc ] [ --gc_stop_thresh perc ] [ --gid pool_gids ] [ --group pool_groups ] [ --help ] [ --max_lifetime max_lifetime ] [ --max_pintime maxpintime ] [ --ret_policy retention_policy ] [ --s_type space_type ] DESCRIPTION
dpm-modifypool modifies a disk pool definition. This command requires ADMIN privilege. OPTIONS
pool_name specifies the disk pool name. It must be at most CA_MAXPOOLNAMELEN characters long. defsize specifies the default amount of space reserved for a file. This is by default in bytes, but the number may also be post-fixed with 'k', 'M' or 'G' for kilobyte, Megabyte and Gigabyte respectively. 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). 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. gc_stop_thresh specifies the percentage of free space in the pool above which the garbage collector is stopped. 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). pool_gids The existing list can be reset using a comma separated list of group gids, extended by prefixing the gid by + or reduced by prefix- ing the gid by -. See examples. pool_groups The existing list can be reset using a comma separated list of group names, extended by prefixing the name by + or reduced by pre- fixing the name by -. The keyword "ALL" means non-dedicated pool. See examples. retention_policy specifies the retention policy supported by the disk pool. It can be R (for Replica), O (for Output) or C (for Custodial). space_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). EXAMPLE
dpm-modifypool --poolname Volatile --def_filesize 100M --groups -dteam,ops,+atlas EXIT STATUS
This program returns 0 if the operation was successful or >0 if the operation failed. SEE ALSO
