# dpm\_modifyfs(3)

modify the parameters of a disk pool filesystem

## NAME

dpm\_modifyfs - modify the parameters of a disk pool filesystem

## SYNOPSIS

**#include \<sys/types.h\>**\
 **#include "dpm\_api.h"**

**int dpm\_modifyfs (char \****server***,** **char \****fs***,** **int** *status***,** **int** *weight***)**

## DESCRIPTION

**dpm\_modifyfs** modifies the parameters of a disk pool filesystem.

- *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**. (-1 will tell the server to not change the current value).

- *weight*

  specifies the weight of the filesystem. This is used during the filesystem selection. The value must be positive (-1 will tell the server to not change the current value). It is recommended to use a value lower than 10.

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**

  Filesystem does not exist.

- **EACCES**

  The caller does not have ADMIN privilege.

- **EFAULT**

  *server* or *fs* is a NULL pointer.

- **EINVAL**

  The length of *server* exceeds **CA\_MAXHOSTNAMELEN** or the length of *fs* exceeds 79.

- **SENOSHOST**

  Host unknown.

- **SEINTERNAL**

  Database error.

- **SECOMERR**

  Communication error.
