What patch version of 2.7?  https://www.cisco.com/c/en/us/products/collateral/security/identity-services-engine/bulletin-c25-2943876.html

hi @ahollifield we are running on patch 6, because of low disk space backup is also getting failed.

[ahollifield]

What size disk do you have allocated to this node?

Was size disk is allocated to this VM?

Hi @ MD SHAHNAWAZ ,

 1st the OPT threshold to generate a Backup is 70% ... to clean some space you have two options:

1. open a TAC Case to clear some old files (via root access)
2. increase your Disk to 600 GB (probably you have less than that)

 2nd if you are facing Replication Issues, please take a look at ISE - Slow Replication , ISE 2.7 P8 or P9 is a MUST !!!

 3rd if you are facing Insufficient Virtual Machine alarms ... please take a look at CSCwe44886  ISE 2.7 patch 8 lowers read test speeds from CLI causing "Insufficient Virtual Machine Resources" , the fix is expected to come out for releases from version 2.7 to 3.2.

Hope this helps !!!
