How to check Avamar node capacity- MSG_ERR_DISKFULL

Last GC: finished Wed Aug 25 01:01:04 2010 after 00m 50s >> recovered 0.00 KB (MSG_ERR_DISKFULL)

The total grid utilization is currently at 88% and I also saw some Unacknowledged Events with the following information:

Code: 4202 Message: failed garbage collection with error MSG_ERR_DISKFULL

This error is a direct result of the garbage collect run limit being reached or exceeded due to excessive checkpoint overhead. To verify and check all of the node capacities use the following commands; also if this is a single node you will not have to use the mapall command.

su – admin

ssh-agent bash

ssh-add ~admin/.ssh/admin_key


mapall –noerror ‘df -h’

This should give you the filesystem for each node including the sizes, used, and space available. Then run:

avmaint nodelist | grep percent-full

This output gives you a true reading of the OS capacity utilization.  On a grid where data nodes use a file pool, the Linux "df" command is not meaningful because the stripes are pre-allocated in the file pool, and many of the stripes might not be in use.
