NAME

na_treecompare - Log of treecompare activities

SYNOPSIS

/etc/log/treecompare

DESCRIPTION

The treecompare log file contains a log of treecompare activities for this filer. The file lives in /etc/log on the root volume.

Every Sunday at midnight, /etc/log/treecompare is moved to /etc/log/treecompare.0; /etc/log/treecompare.0 is moved to /etc/log/treecompare.1; and so on. The suffix can go up to 5, so the old /etc/log/treecompare.5 will be deleted. Treecompare activities are saved for a total of seven weeks.

Each entry of the /etc/log/treecompare file is a single line containing the following space-separated fields.

  timestamp tree1 tree2 event_info

The following is a description of each field.

timestamp
Displayed in ctime() format, e.g. Fri Jul 17 20:41:09 GMT. Indicates the time this event was recorded.

tree1 The name of the host1 and the full path for tree1 as shown below:

  host1:tree1_path

tree2 The name of the host2 and the full path for tree2 as shown below:

  host2:tree2_path

event_info
The event which is being logged. Some events may have extra information in parentheses. The existing event types are:

Start (cmp_level={data|checksum}, {compare|ignore} NT ACL)
The beginning of a treecompare session. The command options are included in the parentheses.

End (tree1_only=num_1, tree2_only=num_2, mismatch=num_3) The completion of a treecompare session. The summary of the session is included in the parentheses.

EXAMPLE

A typical treecompare session in /etc/log/treecompare looks like:
  Tue Jun 24 00:05:20 GMT fridge:/vol/src1/.snapshot/snap1/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 Start (cmp_level = data, compare NT ACL)
  Tue Jun 24 00:05:44 GMT fridge:/vol/src1/.snapshot/snap1/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 End (tree1_only = 0, tree2_only = 0, mismatch = 0)

This example shows a treecompare session which used comparison level data and did compare NT ACLs. At the end of the session, the summary shows no mismatches were found.

The next example shows a log with several mismatches.

  Tue Jun 24 00:07:31 GMT fridge:/vol/src1/.snapshot/snap2/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 Start (cmp_level = checksum, ignore NT ACL)
  Tue Jun 24 00:07:32 GMT fridge:/vol/src1/.snapshot/snap2/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 Atime_differ (.)
  Tue Jun 24 00:07:32 GMT fridge:/vol/src1/.snapshot/snap2/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 Atime_differ (./subd1)
  Tue Jun 24 00:07:42 GMT fridge:/vol/src1/.snapshot/snap2/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 Atime_differ (./subd1/dfile2)
  Tue Jun 24 00:07:42 GMT fridge:/vol/src1/.snapshot/snap2/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 Mtime_differ (./subd1/dfile2)
  Tue Jun 24 00:07:42 GMT fridge:/vol/src1/.snapshot/snap2/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 Size_differ (./subd1/dfile2)
  Tue Jun 24 00:07:42 GMT fridge:/vol/src1/.snapshot/snap2/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 Data_differ (block 0 in ./subd1/dfile2)
  Tue Jun 24 00:07:51 GMT fridge:/vol/src1/.snapshot/snap2/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 Data_differ (block 1000 in ./subd1/dfile2)
  Tue Jun 24 00:07:52 GMT fridge:/vol/src1/.snapshot/snap2/qt1 toaster:/vol/
  dst4/.snapshot/snap1/qt1 End (tree1_only = 0, tree2_only = 0, mismatch = 7)
