Hi Stephan,

Once the volume migration is successful then only CS will delete it from the 
source storage. Please make sure that there are no issues with volume 
migrations.

Subject: Storagemigration / Primary Storages

Hi!

We're currently migrating volumes from one to another storage with the goal to 
get the source LUN freed to finally remove the whole storage.
This runs w/ ACS 4.8 and XenServer 6.5 with attached FC-Storages.

Interestingly, the free space not only decreases (as expected) on the target 
LUN. Also the source LUN is running full during this progress.

By now, I did'nt dug too deep, but maybe anyone had seen this issue.
too? And maybe could give a hint for the reason? ;)

What we had was:
SAS-LUN w/ Tag SAS
SATA-LUN w/ Tag SATA

Every offering is configured with the respective Tags.

What we prepared:
SAS-LUN2 w/ Tags SAS,SASNEW
SATA-LUN2 w/ Tags SATA,SATAMEW
SAS-LUN w/ Tag SASOLD (changed from SAS) SATA-LUN w/ Tag SATAOLD (changed from 
SATA)

Most of the volumes are migrated live via cloudmonkey as simple as:

migrate volume volumeid=[somevolume-on-"old"-lun] storageid=SATA-LUN2 
livemigrate=true

Some of the migration-jobs ran into ACS timouts until we changed 
job.cancel.threshold.minutes to 240 (some of the bigger volumes took some 
amount of time).

Thanks for any suggestions.

- Stephan
