Symptoms

A backup operation for a particular VE fails continuously with the message:

Subscription limit for backup space exceeded

There is enough backup space on the subscription in question.

The node, where VE is located, vm2vf failure messages can be found at the time of the last backup operation:

[root@vz01 ~]# grep PACI /var/log/messages-20170402
Mar 22 00:19:52.857 PACI: FAILURE: Vm2Vf has died unexpectedly

Therefore the backup operation got interrupted, the following messages can be found in /var/log/pa/vps.log on OACI IM node:

2017-03-22 12:19:36,427 (web_96f0ac87-1e01-4c93-855d-1229aaef79b3) ERROR Pipeline [Shared executor thread #1 @1 @INTERACTIVE] - Unexpected failure of the com.parallels.c2u.im.tasks.OnDemandBackupTask invocation at pipeline #1273 [(ON_DEMAND_VE_BACKUP for: VeId[1000003.server-1000009-1]), created at node [im1], step 1 ([BACKUP]), mode: EXEC, state:TASK_IN_PROGRESS, reqIs: null]

Cause

There is a stuck backup operation in OACI. The message is shown, because consumed backup space is calculated by the existing backups + the space required for an active backup operation (that is stuck). While the backup operation is in progress, the space required is set to VM's HDD limit, which is usually quite larger and may easily exceed the backup space limit.

Resolution

Restart OACI IM services to release the stuck backup operation:

# service PACI-im restart

The restart will cause unavailability of OACI tabs in OSA Control Panel. In case it is not possible to restart the service, contact Odin Technical Support to apply a direct fix without restart.
