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
              Metadata checksum validation failed while performing the query.

       EFSCORRUPTED
              Metadata corruption was encountered while performing the query.

       EIO    An I/O error was encountered while performing the query.

       EPERM  Caller did not have permission to shut down the filesystem.
