Symptoms

You are backing up a Linux machine to an NFS share.

Consolidation, replication, or cleanup fails with:

Error code: 35
Module: 64
LineInfo: 95962d9a14426f08
Fields:  volume : 2016_01_04_13_33_06_333D.TMP, $module : disk_bundle_lxa64_pic_44124
Message: Failed to replace the volume.

Cause

After backup, the backup file is not unlocked for other operations. Windows NFS server does not work correctly with byte range locks which results in a deadlock on NFS server side.

Solution

  1. On the Linux machine, open /usr/sbin/acronis_mms in an editor, for example, vi:
    vi /usr/sbin/acronis_mms
  2. Press i to enter the editing mode.
  3. After ulimit -s 2048, add this line:
    export MOUNT_NFS_NOLOCK=1
  4. Press Esc to exit the editing mode.
  5. To exit the editor and save changes, issue the following command:
    wq
  6. Restart mms:
    /etc/init.d/acronis_mms restart
