UPDATE-SMART-DRIVEDB(8)                                       SMART Monitoring Tools                                       UPDATE-SMART-DRIVEDB(8)

NAME

       update-smart-drivedb - update smartmontools drive database

SYNOPSIS

       update-smart-drivedb [OPTIONS] [DESTFILE]

DESCRIPTION

       [This man page is generated for the Linux version of smartmontools.  It does not contain info specific to other platforms.]

       update-smart-drivedb updates /var/lib/smartmontools/drivedb/drivedb.h or DESTFILE from smartmontools SVN repository.

       It  tries  to  download  first  from  the  current  branch and then from trunk. The tools used for downloading are either curl(1), wget(1),
       lynx(1), or svn(1).

       The old file is kept if the downloaded file is identical (ignoring the differences in Id string) otherwise it is moved to drivedb.h.old.

OPTIONS

       -s SMARTCTL
              Use the smartctl(8) executable at path SMARTCTL for drive database syntax check.  The form '-s -' disables the  syntax  check.   The
              default is /usr/sbin/smartctl.

       -t TOOL
              Use TOOL for download.  TOOL is one of: curl wget lynx svn.  The default is the first one found in PATH.

       -u LOCATION
              Use URL of LOCATION for download. LOCATION is one of:
              sf (Sourceforge code browser via HTTPS),
              svn (SVN repository via HTTPS),
              svni (SVN repository via HTTP),
              trac (Trac code browser via HTTPS).
              The default is svn.

       --cacert FILE
              Use CA certificates from FILE to verify the peer.

       --capath DIR
              Use CA certificate files from DIR to verify the peer.

       --insecure
              Don't abort download if certificate verification fails.  This option is also required if a HTTP URL is selected with '-u' option.

       --dryrun
              Print download commands only.

       -v     Verbose output.

EXAMPLES

       # update-smart-drivedb
       /var/lib/smartmontools/drivedb/drivedb.h updated from branches/RELEASE_6_6_DRIVEDB

EXIT STATUS

       The exit status is 0 if the database has been successfully updated. If an error occurs the exit status is 1.

FILES

       /usr/sbin/update-smart-drivedb
              full path of this script.

       /usr/sbin/smartctl
              used to check syntax of new drive database.

       /var/lib/smartmontools/drivedb/drivedb.h
              current drive database.

       /var/lib/smartmontools/drivedb/drivedb.h.old
              previous drive database.

       /var/lib/smartmontools/drivedb/drivedb.h.error
              new drive database if rejected due to syntax errors.

       /var/lib/smartmontools/drivedb/drivedb.h.lastcheck
              empty file created if downloaded file was identical.
