Try running the du command by itself from the command line. I'm thinking it might be outputting something more than just an interger. If so then that's why it's unable to compare it with another interger and so the test fails.

If the output is more spitting out more than just a number, then you might want to pipe it through awk to get the field you need. I would suggest assigning the output to a variable and then using that in your test statement. Let me know what happens.

cmap_set

CMAP_SET(3)					    Corosync Cluster Engine Programmer's Manual 				       CMAP_SET(3)

NAME

       cmap_set - Store value in CMAP

SYNOPSIS

       #include <corosync/cmap.h>

       cs_error_t cmap_set (cmap_handle_t handle, const char *key_name, const void *value, size_t value_len, cmap_value_types_t type);

       Also shortcuts for different types are defined

       cs_error_t cmap_set_int8(cmap_handle_t handle, const char *key_name, int8_t value);

       cs_error_t cmap_set_uint8(cmap_handle_t handle, const char *key_name, uint8_t value);

       cs_error_t cmap_set_int16(cmap_handle_t handle, const char *key_name, int16_t value);

       cs_error_t cmap_set_uint16(cmap_handle_t handle, const char *key_name, uint16_t value);

       cs_error_t cmap_set_int32(cmap_handle_t handle, const char *key_name, int32_t value);

       cs_error_t cmap_set_uint32(cmap_handle_t handle, const char *key_name, uint32_t value);

       cs_error_t cmap_set_int64(cmap_handle_t handle, const char *key_name, int64_t value);

       cs_error_t cmap_set_uint64(cmap_handle_t handle, const char *key_name, uint64_t value);

       cs_error_t cmap_set_float(cmap_handle_t handle, const char *key_name, float value);

       cs_error_t cmap_set_double(cmap_handle_t handle, const char *key_name, double value);

       cs_error_t cmap_set_string(cmap_handle_t handle, const char *key_name, const char *value);

DESCRIPTION

       The  cmap_set  function	is used to store key inside cmap. The handle argument is connection to CMAP database obtained by calling cmap_ini-
       tialize(3) function.  key_name is name of key to set value. Key name is limited by minimal (CMAP_KEYNAME_MINLEN, currently 3)  and  maximal
       (CMAP_KEYNAME_MAXLEN,  currently  255)  length.	Also key can contain only limited set of characters expressed by regexp [a-zA-Z0-9._-/:]*.
       value is pointer to allocated data which will be stored inside CMAP. Length of value (number of bytes) is supplied as value_len	parameter.
       Last parameter is type which gives type of value. It may be one of:

       CMAP_VALUETYPE_INT8 - 8-bit signed interger

       CMAP_VALUETYPE_UINT8 - 8-bit unsigned integer

       CMAP_VALUETYPE_INT16 - 16-bit signed interger

       CMAP_VALUETYPE_UINT16 - 16-bit unsigned integer

       CMAP_VALUETYPE_INT32 - 32-bit signed interger

       CMAP_VALUETYPE_UINT32 - 32-bit unsigned integer

       CMAP_VALUETYPE_INT64 - 64-bit signed interger

       CMAP_VALUETYPE_UINT64 - 64-bit unsigned integer

       CMAP_VALUETYPE_FLOAT - Float value

       CMAP_VALUETYPE_DOUBLE - Double value

       CMAP_VALUETYPE_STRING - C-style string

       CMAP_VALUETYPE_BINARY - Binary data, byte with zero value has no special meaning

RETURN VALUE

       This  call  returns the CS_OK value if successful. If value or key_name are unspecified, CS_ERR_INVALID_PARAM is returned. Too short or too
       long key_name returns CS_ERR_NAME_TOO_LONG error code. Some of keys may be tagged read-only directly in corosync and seting such  key  will
       result in CS_ERR_ACCESS error.

       CS_ERR_TRY_AGAIN Resource temporarily unavailable

       CS_ERR_INVALID_PARAM Invalid argument

       CS_ERR_LIBRARY The connection failed

       CS_ERR_INTERRUPT System call inturrupted by a signal

       CS_ERR_MESSAGE_ERROR Incorrect auth message received
