## NAME
       xfs_logprint - print the log of an XFS filesystem

## SYNOPSIS
       **xfs**___**logprint** [ _options_ ] _device_

## DESCRIPTION
       **xfs**___**logprint**  prints  the  log of an XFS filesystem (see [**xfs**(5)](https://www.chedong.com/phpMan.php/man/xfs/5/markdown)).  The _device_ argument is the
       pathname of the partition or logical volume containing the filesystem. The _device_  can  be  a
       regular  file  if  the  **-f** option is used. The contents of the filesystem remain undisturbed.
       There are two major modes of operation in **xfs**___**logprint**.

       One mode is better for filesystem operation debugging.  It is called the  transactional  view
       and  is  enabled through the **-t** option. The transactional view prints only the portion of the
       log that pertains to recovery. In other words, it prints out  complete  transactions  between
       the tail and the head. This view tries to display each transaction without regard to how they
       are split across log records.

       The second mode starts printing out information from the beginning of the  log.   Some  error
       blocks might print out in the beginning because the last log record usually overlaps the old‐
       est log record. A message is printed when the physical end of the log is reached and when the
       logical  end  of  the  log  is  reached. A log record view is displayed one record at a time.
       Transactions that span log records may not be decoded fully.

## OPTIONS
### -b

### -c

### -C
              Copy the log from the filesystem to the file _filename_.  The log itself is not printed.

### -d

### -D

### -e
              unwind from bad logs.  However, sometimes it just dies in bad ways.  Using this option
              prevents core dumps.

### -f
              _vice_  (see  the  [**mkfs.xfs**(8)](https://www.chedong.com/phpMan.php/man/mkfs.xfs/8/markdown) **-d** _file_ option).  This might happen if an image copy of a
              filesystem has been made into an ordinary file with **xfs**___**[copy**(8)](https://www.chedong.com/phpMan.php/man/copy/8/markdown).

### -l
              External log device. Only for those filesystems which use an external log.

### -i

### -q

### -n

### -o
              formation can be printed.

### -s
              Override any notion of where to start printing.

### -t

### -v

### -V
