Hello
I have opened a case they asked me to increase dataVG cow size on the nodes. But be sure there is sapce on the nodes. you can check with the admins. I have added that additional settings on all the nodes. Then start the backup when data i/o is less on the volumes
Hi
Please check the MongoDB log, and the CVMA log from the Media Agent during the problem-reported time.
Note: Also, you can try to remove the existing snap from to be copied flag and age the snap. Trigger a new snap with backup copy and check the status.
Regards,
Wasim

I have tried that “Also, you can try to remove the existing snap from to be copied flag and age the snap. Trigger a new snap with backup copy and check the status” Once, It is working fine then It fails again with the same error. Error Code: [32:392]
Description: Internal software error occurred. : [Mount failed:OS mount failed (MM.60614) (MM.-335352634)]
CVMA.log looks fine

+2Hello,
How did you determine that you needed to set this value? 156300 ?
if the volume dataVG size 1TB = 1024 GB= 1024000 Mb
1024000 Mb *5% = 51 200 Correct calculation?
Documentation:
Logical Volume Manager (LVM) volume groups must have adequate free space for creating the IntelliSnap snapshots. The default COW cache size is set to 4096 MB or 5% of the volume size, whichever is greater. You can increase the COW cache size.
+8Hi
I have tried . maybe your environment need less space. you should try and find the correct size
