A.1.8 The drd sync command
The drd-sync(1M) command propagates file system changes—whose modification time is newer
than the clone creation time—from the booted original system to the inactive clone image.
NOTE: The initial implementation of drd sync only supports refresh of the inactive clone from
the booted original system.
A file in the root LVM volume group or VxVM disk group on the booted original system is copied
to the inactive clone if all of the following criteria is satisfied:
• The file does NOT reside in the following non-synchronized locations:
— /stand/*
— /tmp/*
— /var/adm/sw/*
— /var/opt/drd/tmp/*
— /var/tmp/*
— /etc/lvmconf*
— /etc/vx/*
— /etc/vxvmconf/*
— /dev/<clone_group>/* (Where clone_group is the name of the LVM group used
to import the clone (usually drd00.) This non-synchronized location does not apply to
VxVM-managed roots.)
• The file does NOT appear in the Installed Products Database (that is, the output of
/usr/sbin/swlist -l file), OR:
— The file appears in the Installed Products Database with the attribute is_volatile set
to true, AND:
— The newconfig templates for the file on the original system and the clone are the same.
A newconfig template is the delivered template for a configuration file that is copied to
create a “volatile” file when some Software Distributor packages are installed.
If the path to the volatile file is path, the path to the newconfig template is generally
/usr/newconfig/<path>, or <product_dir>/newconfig/<path>, where
product_dir is the value of the “directory” product attribute of the product delivering
the volatile file.
If the newconfig templates do not match, or the location of the newconfig template cannot
be determined, the file is not copied.
The files contained in the SW-DIST Installed Products Database are not copied to the clone because
these files are intended to be managed by SW-DIST commands. Similarly, the contents of /var/
adm/sw, which contains the Installed Products Database and logs associated with SW-DIST
commands executed on the booted system, are not copied.
See drd-runcmd(1M) for information about using drd runcmd swinstall to install software to
the clone.
Files containing blocks of binary zeroes that are copied by drd sync are converted to sparse
files on the clone.
The drd runcmd command returns the following error codes:
0 Success
1 Error
2 Warning
The drd sync command syntax is:
