Uploading objects

You can upload objects that are in the LU-mode.

Complete the following steps to upload an object:
  1. Create LU-mode objects on a cloud object storage. 
    # mmafmcosconfig fs1 localupdates --endpoint  http://c1f1u11n07    
 --uid 0 --gid 0  --new-bucket localupdates  --mode lu --cleanup

    A sample output is as follows:

    Created 3 objects on COS: 
Name      : obj1
Date      : 2020-10-23 06:07:29 EDT 
Size      : 2.2 KiB 
ETag      : 6fdfdb7af5eb5ad7f610014985951941 
Type      : file 
Metadata  :
  Content-Type: application/x-sh 

Name      : obj2
Date      : 2020-10-23 06:07:31 EDT 
Size      : 2.2 KiB 
ETag      : 6fdfdb7af5eb5ad7f610014985951941 
Type      : file

Size      : 2.2 KiB 
ETag      : 6fdfdb7af5eb5ad7f610014985951941 
Type      : file 
Metadata  :
  Content-Type: application/x-sh
  2. Download the created objects. 
    # mmafmcosctl fs1 localupdates /gpfs/fs1/localupdates/ download  --all

    A sample output is as follows:

    Queued         Failed       AlreadyCached          TotalData
                                                (approx in Bytes)
          3              0                  0                6816 
Object Download successfully queued at the gateway.
  3. Check the fileset status. 
    # mmafmctl fs1 getstate

    A sample output is as follows:

    Fileset Name  Fileset Target                     Cache State   Gateway Node Queue Length Queue numExec 
------------  --------------                     ------------- ------------ ------------  ------------- 
localupdates  http://c1f1u11n07:80/localupdates  Active         c7f2n05      0            10
  4. Write data into objects, which will not be synchronized to a cloud object storage. 
    # echo 11111 >> /gpfs/fs1/localupdates/obj1
# echo 11111 >> /gpfs/fs1/localupdates/obj2
  5. Check the fileset status. 
    # mmafmctl fs1 getstate

    A sample output is as follows:

    Fileset Name  Fileset Target                     Cache State   Gateway Node Queue Length Queue numExec 
------------  --------------                     ------------- ------------ ------------  ------------- 
localupdates  http://c1f1u11n07:80/localupdates  Active         c7f2n05      0            10

    These changes are local and are not pushed to the cloud object storage because it is in the LU-mode.

  6. To synchronize objects to a cloud object storage, upload the objects. 
    # mmafmcosctl fs1 localupdates /gpfs/fs1/localupdates upload --all

    Sample outputs are as follows:

    Queued         Failed                TotalData
                                  (approx in Bytes)
         3               0                     6828 
Object Upload successfully queued at the gateway.
