NAME
       ioctl_xfs_goingdown - shut down an XFS filesystem


SYNOPSIS
       #include <xfs/xfs_fs.h>

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


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


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

       EFSBADCRC
