UCCX - LowActivePartitionAvailableDiskSpace

[Torsten G]

The UCCX (10.6.1.11001-31) send the following message:

LowActivePartitionAvailableDiskSpace has occured. Counter Percent Available of Partition(Active) on node SERVERNAME has value of 0 which is under low threshold 4

After a reboot, the Server don't start complete. The Webservice is down.

admin:show diskusage tmp

This command can take significantly long time,
and can also effect the system wide IOWAIT on your system.
Continue (y/n)?y
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2        26G   26G     0 100% /

The tmp-directory is complete in used.

What can i do?

This issue mainly happens because of the excessive generation of Assert and Shmem files mostly in the below location:

/usr/local/cm/db/informix/tmp

that fills the tmp folder which in return fills the active partition to 100%

Contact TAC and they will help you in removing these files from the root directly. No other workaround is there

Thanks.

and without a service contract?

[Deepak Rawat]

Not possible as only TAC can help you in getting the root account access.

Perhaps you could boot the vm from a Linux liveCD, mount the hard disk and clean that directory by yourself.
