-Synopsis
-
-amcheck [-am] [-w] [-sclt] [-M address] config [ host [disk...] ...] [ -
-o configoption]...
-
-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. Multiple specific clients can be checked by
- specifying the client name.
-
- -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. If the
- label_new_tapes option is enabled, this check may ERASE any non-Amanda
- tape in the drive or changer. The check enable the tape tests on the
- server host 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.
-
- -M address
- Mail the report to address instead of the mailto value from amanda.conf.
- Implies -m.
-
- host [disk]*
- Specify the host and disk on which the command will work.
-
- -o configoption
- See the "CONFIGURATION OVERRIDE" section in amanda(8).
-
-The default is -cs.
-
-EXAMPLES
-
-In this example, both the tape server and client tests are run. The results are
-displayed on standard output.

- % amcheck daily
- 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.
-
- Amanda Backup Client Hosts Check

-
-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.

-
- ERROR: XXX dir directory: not writable
- (error) Directory directory is either not writable, i.e. the dump user

-
-
- NOTE: XXX dir directory: does not exist
- (info) A database (info) or index directory does not exist or cannot be

- (info) This indicates the info directory listed in the previous message
- will be created on the next run.

- (error) Amcheck expected name to be a directory, but it is something else
- (e.g. file).
-
- WARNING: info file file: does not exist

- 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).

- (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

- (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.
