To ensure that setting a high timeout value for snapshot backup operation
will not affect vCenter connections made for any other operations besides
volume snapshot, split the existing vCenter session timeout configuration into
two configurations,
1. To tune timeout value for CS's session vCenter during snapshot backup
operation - 'vmware.snapshot.backup.session.timeout' (new; default: 20 minutes)
2. For all other operations - 'vmware.vcenter.session.timeout' (existing;
default: 20 minutes)
Additional change -
Users could potentially run into a timeout issue while trying to snapshot
large VMs. There is a timeout for async-jobs that ensures that any job that has
been in process for too long is cancelled by CSMS. This timeout is configurable
using a global configuration âjob.cancel.threshold.minutesâ and it defaults
to 1 hour.
Now for large volumes even though users configure other snapshot timeout
values (âvmware.snapshot.backup.session.timeoutâ and
âbackup.snapshot.waitâ) to a very high value, the snapshot operation will
still fail because the job will be cancelled in 1 hour.
Hence proposing a configuration that will allow admins to separate out the
job cancellation timeout for âvolume snapshotâ jobs from other vm work jobs
- 'volume.snapshot.job.cancel.threshold'.
