Sync_by_file of TFS Data Migration

in this article, I followed an article that introduced the TFS 2.2.16 version uses the syn_by_file tool to implement data migration between two sets of TFS Systems based on file names . The test environment is consistent with the previous article.

One: Clear the data on target at the end of the previous migration

#/usr/local/tfs/bin/ssm-s 192.168.1.12:8108show > block

#/usr/local/tfs/scripts/stfs format 1-3#/usr/local/tfs/scripts/tfs stop_ns#/usr/local/tfs/scripts/tfs Start_ns #/ Usr/local/tfs/scripts/tfs Start_ds 1-3 DataServer 1 is up successfully pid:25002 DataServer 2 are up SUCCESSFULLY pid:25 001 DataServer 3 is up successfully pid:25000

Second: After reformatting the dataserver mountpoint ,thetarget Environment reverts to the initial state before the migration

#/usr/local/tfs/bin/ssm-s 192.168.1.12:8108show > block

Three: Prepare a list of file names

after the last migration, the list will be logs directory generated sync_succ_file files, copy the contents of the file can be. Note that the file name may be duplicated.

# tail-5/tmp/file1.txt T1mtdtbmv41r4baz6kt1mtdtbk_41r4baz6kt1mtdtbka41r4baz6kt1mtdtbtd41r4baz6kt1mtdtbg_ 41r4baz6k # wc-l/tmp/file1.txt 10730/tmp/file1.txt # uniq/tmp/file1.txt |wc-l9575

Four: Start migration

#/usr/local/tfs/bin/sync_by_file-s 192.168.1.229:8108-d 192.168.1.12:8108-f/tmp/file1.txt-m 20140926-l error-s parameter specified The nameserver IP and Port-d parameter of source specifies the IP and port-F parameters of the target (destination) for the specified list of file name-m parameters of the nameserver. File modification time files after the-m parameter value are ignored and not synchronized. The-l parameter represents the log level, and the default is info
