Writing new data with strict replication when a disk is offline

In this scenario, strict replication is enforced for a file system and then a disk that is used by the file system is deleted, replaced, or suspended. If IBM Storage Scale then tries to create or append data to an existing file in the file system, the operation can fail with an ENOSPC error.
Note: To determine whether a file system has strict replication enforced, issue the following command:
mmlsfs fs1 -K
To write or append the data, follow these steps:
  1. Disable strict replication.
  2. Write the data.
  3. Re-enable strict replication.
  4. Issue the following command to migrate data off the suspended disk:
    mmrestripefs fs1 -r
