HybriStor Version 2.3.111 or Below Fails with Large Files Over 4 TB

Follow

During recent testing, a major bug was found in the HybriStor software that will not allow files larger than 4 TB to be backed up to shares. A new HybriStor version, 2.3.112, has been released to correct this problem. Please read the below cases before attempting to backup files larger than 4 TB.

Case 1:

HybriStor appliance version is 2.3.112 and all of your NFS/CIFS shares were created on the 2.3.112 version.

Resolution:

No resolution is needed. Files over 4 TB should be backed up successfully.

 

Case 2:

HybriStor appliance version is 2.3.112 or below and you have not backed up any files greater than 4 TB.

Resolution:

There will be no issues with your HybriStor appliance at this time. If you will need to backup files larger than 4 TB in the future, please open a Hybristor support ticket from the UI Support -> Contact Us -> Create Support Ticket so we can assist. However you can correct the issue yourself by following the steps outlined below:

  1. Upgrade your HybriStor appliance to version 2.3.112 if needed using the UI page found at Support -> Upgrade HybriStor. The HybriStor upgrade bin file can be found here: https://support.neverfail.com/hc/en-us/articles/115002785488
  2. Once the HybriStor appliance is upgraded, create a new temporary NFS/CIFS share that will be used for migrating share data. (This share can be called whatever you choose)
  3. Use the built in share Data Migration feature found in the UI at Configurations -> Data Migration. Migrate all data from the original NFS/CIFS share to the newly created temporary share (Attached is a recording on how to use this tool).
  4. Once data migration is complete, delete the original NFS/CIFS share.
  5. Recreate the original NFS/CIFS share with same name as before.
  6. Use the Data Migration tool once again, this time migrating the data from the temporary NFS/CIFS share to the recreated original share.
  7. Delete the temporary NFS/CIFS share created used in the migration process.

The above steps (2 - 6) must be followed for each NFS/CIFS share on the appliance you wish to backup files larger than 4 TB too.

If the outlined process is too confusing to follow, again please contact HybriStor support by opening a support ticket using the UI page Support -> Contact Us -> Create Support Ticket so we can assist you.

 

Case 3:

HybriStor appliance version is 2.3.112 or below and you have received errors when attempting to backup files larger than 4 TB similar to:

Resolution:
