Evicting data or objects by using the manual updates mode of the AFM to cloud object storage

The replication of the AFM to cloud object storage file system by using manual updates mode does not support automatic eviction, instead data or objects can be evicted by using mmafmcosctl evict command.

Procedure

  1. List the file systems. 
     ls -lash /gpfs/fs3
total 81M
256K drwxr-xr-x     4 root root 256K May 19 10:44 .
4.0K drwxrwxrwx     6 root root 4.0K May 19 03:29 ..
 512 drwx------     2 root root 4.0K May 19 03:35 .afm
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file1
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file10
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file2
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file3
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file4
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file5
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file6
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file7
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file8
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file9
 512 drwx------ 65535 root root 4.0K May 19 03:35 .ptrash
 512 dr-xr-xr-x     2 root root 8.0K Dec 31  1969 .snapshots
  2. Upload all files to the bucket on the cloud object storage. 
     mmafmcosctl fs3 root /gpfs/fs3/ upload --all
     Queued         Failed                TotalData
                                  (approx in Bytes)
        10               0                 83588400 
Object Upload successfully queued at the gateway.
  3. Create an evict file to evict these files. 
    cat >  /evictfile
/gpfs/fs3/file1
/gpfs/fs3/file2
/gpfs/fs3/file3
/gpfs/fs3/file4
/gpfs/fs3/file5
  4. Check how many files are evicted. 
    cat >  /evictfile
/gpfs/fs3/file1
/gpfs/fs3/file2
/gpfs/fs3/file3
/gpfs/fs3/file4
/gpfs/fs3/file5
  5. Check contents of the file system. 
     ls -lash /gpfs/fs3
total 41M
256K drwxr-xr-x     4 root root 256K May 19 10:44 .
4.0K drwxrwxrwx     6 root root 4.0K May 19 03:29 ..
   0 -rwxr-xr-x     1 root root 8.0M May 19 10:44 file1
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file10
   0 -rwxr-xr-x     1 root root 8.0M May 19 10:44 file2
   0 -rwxr-xr-x     1 root root 8.0M May 19 10:44 file3
   0 -rwxr-xr-x     1 root root 8.0M May 19 10:44 file4
   0 -rwxr-xr-x     1 root root 8.0M May 19 10:44 file5
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file6
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file7
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file8
8.0M -rwxr-xr-x     1 root root 8.0M May 19 10:44 file9

    Here, the file1 through file5 files are evicted.
