NAME         top

       ioctl_xfs_goingdown - shut down an XFS filesystem

SYNOPSIS         top

       #include <xfs/xfs_fs.h>

       int ioctl(int fd, XFS_IOC_GOINGDOWN, uint32_t flags);

DESCRIPTION         top

       Shuts down a live XFS filesystem.  This is a software initiated
       hard shutdown and should be avoided whenever possible.  After
       this call completes, the filesystem ill be totally unusable until
       the filesystem has been unmounted and remounted.

       flags can be one of the following:

           XFS_FSOP_GOING_FLAGS_DEFAULT
                  Flush all dirty data and metadata to disk, flush
                  pending transactions to the log, and shut down.

           XFS_FSOP_GOING_FLAGS_LOGFLUSH
                  Flush all pending metadata transactions to the log and
                  shut down, leaving all dirty data unwritten.

           XFS_FSOP_GOING_FLAGS_NOLOGFLUSH
                  Shut down immediately, without writing pending
                  transactions or dirty data to disk.

RETURN VALUE         top

       On error, -1 is returned, and errno is set to indicate the error.

       Error codes can be one of, but are not limited to, the following:
