VRTSvxfs

The vxfs_vol_queryflags() function returns volume flags information for the volumes specified in the *qinfop argument. If the getall argument is zero, information is returned for volumes specified in the *qinfop argument. The *countp argument must contain the number of volumes specified in the array pointed to by the *qinfop argument.

The file descriptor fd must be the mount point of the file system.

If the getall argument is non-zero, information is returned for all component volumes in a multi-volume file system. Upon entry, *countp must contain the number of structures in the array pointed to by *qinfop. On return, *countp is updated with the number of records that were filled. If the error E2BIG is returned, *countp contains the minimum number of records necessary for the call to succeed.

The contents of the structure pointed to by *qinfop are as follows:

struct fsvol_queryinfo {
       uint64_t         vol_flags;
       char             vol_name[FSVOL_NAMESZ];
}

The fields of *qinfop are as follows:

vol_flags	Returns flags that are currently set on the volume.
vol_name	Contains the name of the component volume.

vxfs_vol_queryflags() returns zero on success, non-zero on failure.

E2BIG	The amount of data to return is too large to fit in the specified array.
EFAULT	One or more of the specified pointer arguments points to an illegal address.
EINVAL	The number of structures specified is incorrect.
ENOENT	The specified volume does not exist.
ENOSYS	There is no license installed to allow this operation.
ENOTSUP	This operation is not supported by the disk layout version of the specified file system. Use vxupgrade(1m) to enable this operation.
EPERM	The calling process does not have correct access privileges.
ENXIO	There is no such device or address.
EROFS	The specified file system is mounted read-only.
