ioctl_xfs_goingdown - shut down an XFS filesystem
#include <xfs/xfs_fs.h> int ioctl(int fd, XFS_IOC_GOINGDOWN, uint32_t flags);
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.
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: 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.
This API is specific to XFS filesystem on the Linux kernel.
