  • Plesk 12.0 for Linux


Backup file can not be downloaded from Tools & Settings > Backup Manager. Nothing happens while clicking on backup file and server became working slower.

Checking disk space, you can see that disk ran out of free space on one of its partitions:

# df -h
Filesystem         Size  Used Avail Use% Mounted on
/dev/ploop10434p1   40G  40G   0G   100% /
none               2.0G  4.0K  2.0G   1% /dev
none               2.0G   12K  2.0G   1% /dev/shm


When backup files are downloaded from the local repository, Plesk creates temporary files in the following directories:

/usr/local/psa/PMM/tmp        <----Full backups
/usr/local/psa/tmp            <----Domains backups

If there is a lack of disk space on the drive where those directories are located, the issue described above will take place.


To maintain consistency, do bind-mounting for folders above:

  1. Remove any symlinks for these folders as they will not work.

  2. Verify that no tasks are running in the Backup and Migration managers.

  3. Stop the Plesk service:

    # service psa stop
  4. Bind-mount the corresponding directories. For example, there is the following extra volume:

    # mount | grep data
     /dev/hdc1 on /data type ext3 (rw)

    Simply bind directories from this volume to the Plesk tree, where it should be:

    # pwd
    # mount --bind /data/PP/psa_tmp tmp
    # pwd
    # mount --bind /data/PP/psa_pmm_tmp tmp
    # mount | grep data
    /dev/hdc1 on /data type ext3 (rw)
    /data/PP/psa_tmp on /usr/local/psa/tmp type none (rw,bind)
    /data/PP/psa_pmm_tmp on /usr/local/psa/PMM/tmp type none (rw,bind)

    The /dev/hdc1 volume is mounted to the /data folder, so /data/PP/psa_tmp and /data/PP/psa_pmm_tmp are bind-mounted from this volume to temporary directories.

  5. Start Plesk service:

    # service psa start
  6. Add the corresponding entries to /etc/fstab for auto-mounting of these folders after reboot:

    /data/PP/psa_tmp /usr/local/psa/tmp none bind
    /data/PP/psa_pmm_tmp /usr/local/psa/PMM/tmp none bind

    Warning: Be very careful editing /etc/fstab. Even a simple mistake can lead to a situation when the server will not boot.
