+amcheck \14 run AMANDA self-checks
+
+Synopsis
+
+amcheck [-mwsclt ] [-Maddress ] config [ host [disk...]...]
+
+DESCRIPTION
+
+Amcheck runs a number of self-checks on both the AMANDA tape server host and
+the AMANDA client hosts.
+On the tape server host, amcheck can go through the same tape checking used at
+the start of the nightly amdump run to verify the correct tape for the next run
+is mounted.
+Amcheck can also do a self-check on all client hosts to make sure each host is
+running and that permissions on filesystems to be backed up are correct.
+You can specify many host/disk expressions, only disks that match an expression
+will be checked. All disks are checked if no expressions are given.
+See the amanda(8) man page for more details about AMANDA.
+
+OPTIONS
+
+
+
+ -s
+ Run the tape server local and tape checks (same as -lt).
+
+ -c
+ Run the client host checks.
+
+ -l
+ Run the local tests (e.g. permissions) on the server host.
+
+ -t
+ Run the tape tests on the server host.
+
+ -w
+ Enables a destructive check for write-protection on the tape (which would
+ otherwise cause the subsequent amdump to fail). If the tape is writable,
+ this check causes all data after the tape label to be erased (actually
+ depends on the device driver: there is no portable non-destructive way to
+ check for write-protection). The check implies -t and is only made if the
+ tape is otherwise correct.
+
+ -m
+ Nothing is printed, but mail is sent if any errors are detected. The mail
+ goes to the mailto address specified in the amanda.conf file or the
+ address value if -M is set.
+
+ -a
+ Like -m but the mail is always sent.
+
+ -Maddress
+ Mail the report to address instead of the mailto value from amanda.conf.
+ Implies -m.
+
+The default is -cs.
+
+EXAMPLES
+
+In this example, both the tape server and client tests are run. The results are
+displayed on standard output.

+ AMANDA Tape Server Host Check
+ -----------------------------
+ /amanda2/amanda/work: 911475 KB disk space available, that's plenty.
+ NOTE: skipping tape-writable test.
+ Tape VOL10 label ok.
+ Server check took 34.966 seconds.

+ WARNING: northstar: selfcheck request timed out. Host down?
+ WARNING: drinkme: selfcheck request timed out. Host down?

+
+ (brought to you by AMANDA 2.4.5)
+
+In this example, if the line mailto csd-amanda is in amanda.conf, mail will be
+sent to csd-amanda if the server check returns an error.

+ (warning) Program program needed on the tape server exists but should be

+
+ ERROR: XXX dir directory: not writable
+ (error) Directory directory is either not writable, i.e. the dump user
+ will not be able to create or remove files, or cannot be accessed,
+ perhaps because a parent directory does not allow search permission. The
+ XXX may be:
+
+
+ log

+
+ oldlog
+ for the directory that holds the old log files (see logdir in
+ amanda.conf)

+ for the AMANDA tapelist directory (see tapelist in amanda.conf)
+
+
+ NOTE: XXX dir directory: does not exist
+ (info) A database (info) or index directory does not exist or cannot be
+ accessed. This might just mean this is a new client or disk, but if that
+ is not the case, this should be treated as an error.
+
+ NOTE: it will be created on the next run
+ (info) This indicates the info directory listed in the previous message
+ will be created on the next run.
+
+ ERROR: XXX dir name: not a directory
+ (error) Amcheck expected name to be a directory, but it is something else
+ (e.g. file).
+
+ WARNING: info file file: does not exist
+ (warning) File file does not exist in the text format database. Since the
+ parent directories do exist, the file should already have been created.

+ (e.g. file).
+
+ ERROR: info file file: not readable
+ (error) The text format database file file is not readable.
+
+ ERROR: log file file: not writable
+ (error) Log file file (file log in logdir from amanda.conf) is either not
+ writable, or cannot be accessed, perhaps because a parent directory does
+ not allow search permission.

+ (error) AMANDA tape list file tapelist (see tapelist in amanda.conf) is
+ not writable or was not found.
+

+ could not be read or parsed.
+
+ WARNING: tapedev is /dev/null, dumps will be thrown away
+ (warning) The tapedev parameter in amanda.conf is set to /dev/null and
+ AMANDA uses that when debugging to throw all the dump images away.
+
+ WARNING: hold file file exists
+ (info) Hold file file exists and will cause amdump to pause at the
+ beginning until it is removed.
+
+ ERROR: holding disk disk: statfs: error message
+ (error) An error was returned from the statfs system call on holding disk
+ disk (maybe because it does not exist).
+
+ ERROR: holding disk disk: not writable
+ (error) Holding disk disk, is not writable, probably because the caller
+ does not have write permission or a parent directory does not allow
+ search permission.
+
+ WARNING: holding disk disk: available space unknown N KB requested.
+ (warning) Amcheck could not determine the amount of available space on
+ holding disk disk to see if there were at least N KBytes available.
+
+ WARNING: holding disk disk: only F KB free (R KB requested).
+ (warning) amanda.conf requested R KBytes of free space on holding disk
+ disk, but only F KBytes were available. 10 MBytes is subtracted for each
+ backup process (see the inparallel amanda.conf option) to allow for
+ unexpected overruns.
+
+ Note
+
+ Even though this message is listed as a warning, it causes amcheck to
+ exit with a non-zero status.
+
+
+
+ Holding disk disk: N KB disk space available, that's plenty.
+ (info) There was sufficient free space on holding disk disk.
+
+ WARNING: holding disk disk: only F KB free, using nothing

+ enough for what is requested in amanda.conf.
+

+ (info) Holding disk disk has F KBytes of free space and AMANDA will be
+ using up to U Kbytes.

+ (error) Tape label is OK, but the write enable test failed.
+
+ Tape label is writable.
+ (info) Tape label is OK and the write enable test succeeded.
+
+ NOTE: skipping tape-writable test.
+ (info) The tape write test (see the -w option) was not enabled.
+
+ WARNING: skipping tape test because amdump or amflush seem to be running,
+ WARNING: if they are not, you must run amcleanup,
+ (warning) It looked to amcheck like either amdump or amflush were running
+ because a log file or amdump file exists. If they are not running, you
+ probably need to run amcleanup to clear up a previous failure. Otherwise,
+ you need to wait until they complete before running amcheck.
+
+ NOTE: skipping tape checks
+ (info) The tape tests are being skipped because you used the -t command
+ line option.
+
+ WARNING: compress is not executable, server-compression and indexing will not
+ work
