Summary

A recently reported RAID 5 and RAID 6 rebuilding failure issue may cause data corruption in QNAP NAS devices with the following settings:

  • Predictive S.M.A.R.T. migration is enabled.
  • The NAS contains one or more RAID 5 or RAID 6 groups.
  • One or more disks are configured as dedicated or global hot spare disks.

If QTS detects that a disk in a RAID 5 or RAID 6 group is abnormal when “Predictive S.M.A.R.T. migration” is enabled, it will start migrating data from the abnormal disk to a spare disk. If the abnormal disk is unplugged or fails during migration, data may get corrupted during the rebuilding process.

We have already fixed these issues in the following QTS versions:

  • QTS 4.3.4.0734 build 20181008
  • QTS 4.3.5.0722 build 20181007

For more information about this issue, visit:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v4.4.159&id=ccae23ff45ccd3e9c610c46ee8449c2617118daa

Solution

To resolve this issue, update QTS to latest version.

Installing the Update

  1. Log on to QTS as administrator.
  2. Go to Control Panel > System > Firmware Update.
  3. Under Live Update, click Check for Update.
    QTS downloads and installs the latest available update.

Tip: You can also download the build from the QNAP website. Go to Support > Download, and then perform a manual update.
