2523 FATAL vix_cant_create VIX can't create /var/tmp/vix/ (4044824)

VA-Based backups for 1 or many machines fail with one of the following errors:

Error Code 1: 2523 - FATAL vix_cant_create VIX can't create /var/tmp/vix/dUUID/config [at vddkd_init:XXX] [at vix_open_conn:XXX]

Error Code 2: 2523 - mkdir: cannot create directory /var/tmp/vix/: Read-only file system

CAUSE 1:

The process in the virtual appliance crashed while consuming 100% of vCPU or RAM resources.

CAUSE 2:

Ranger creates temporary dir at /var/tmp/vix for each backup run. At some point maximum number of files in single dir is reached and OS refuses to create a new directory.

Make sure there are no Jobs running in vRanger before applying any of the Resolutions.

RESOLUTION 1:

Add more CPU or RAM resources to the virtual appliance. We recommend to start with 4 vCPU and 4 GB of RAM, then adjust depending on the size of the environment.

There are two ways to configure the vCPU and RAM resources for the VAs. Make sure you're not running any Job:

• In the vRanger User Interface go to Tools | Options | Virtual Appliance Configuration | Check the VA (only one at the time) | Click Edit.
  • Configure CPU and Memory | Click OK.
• In the vCenter User Interface Right-Click the VA | Power | Shut Down Guest OS.
  • Right-Click the VA | Edit Settings... | Configure CPU and Memory | Click Ok.

   

RESOLUTION 2:

Log in the VA using VMware's Console or Putty, the OS is Linux based.

Run the following commands:

•  cd /var/tmp/vix
• rm -r *  
• reboot

You can additionally run this command to see the number of temp directories:

• Ls /var/tmp/vix | wc -l
