test_io_device

The test_io_device command allows you to check whether the I/O operations and privileges supported by the backup medium meet the backup and restore requirements.

Introduction

The syntax is as follows:

./ob_admin test_io_device -d'<file_path>' -s'<verify_info>'

-d specifies the simulated backup path, which must be an empty directory. -s specifies the authentication information of object storage. For object storage, both -d and -s are required. For Network File System (NFS) storage, only -d is required.

Examples

Here are some examples of using the test_io_device command:

• Specify only -d

  ./ob_admin test_io_device -d'file:///data/nfs'
  

  The test passes if SUCCESS is returned for each module as follows:

  succ to open, filename=/tmp/ob_admin.log, fd=3, wf_fd=2
  succ to open, filename=/tmp/ob_admin_rs.log, fd=4, wf_fd=2
  |test dest connnectivity result|SUCCESS
  |       test archive log result|SUCCESS
  |       test backup data result|SUCCESS
  |       test consume log result|SUCCESS
  | test clean backup file result|SUCCESS
  

• Specify both -d and -s

  ./ob_admin test_io_device -d'oss://home/admin/backup_info' -s'host=http://oss-cn-hangzhou.aliyuncs.com&access_id=111&access_key=222'
  

  The test passes if SUCCESS is returned for each module as follows:

  succ to open, filename=/tmp/ob_admin.log, fd=3, wf_fd=2
  succ to open, filename=/tmp/ob_admin_rs.log, fd=4, wf_fd=2
  |test dest connnectivity result|SUCCESS
  |       test archive log result|SUCCESS
  |       test backup data result|SUCCESS
  |       test consume log result|SUCCESS
  | test clean backup file result|SUCCESS
