is hold mpath device and WILL BE SKIPPED

Post by dcampregher » Apr 09, 2019 2:41 pm

Hello!

We are trying to do a backup of one OEL 6.1 server, but the GUI ( Managed Backup ) show the message: No objects to backup.

The Job.log show the my "/backup" volume will be skiped because it is a mpath device. So, all the volumes using OEL are mpath volumes because are in the HPE iSCSI Storage.

Code: Select all

[09.04.2019 11:03:30] <140283577087744> lpbcore| WARN|Device [/dev/sdb] (8:16) is hold mpath device [249:0] and WILL BE SKIPPED.

The new option in the Updte4a, permit that i make backup from Veeam Agent Linux without the Snapshot, like the NFS directories.

Oh, OK, thank you for clarification. I'd like to ask you to contact support anyway because this is certainly not by design and has to be investigated because:

1. Snapshots are expected to work fine on multipath iSCSI devices
2. The log clearly shows that the problem has nothing to do with snapshots and is likely connected with the enumerator.

P.S. Also please keep in mind that the "crash" mode may result in inconsistencies in your backups.

Thanks!

Using the snapshot-less backup to copy, for example, the /backup/datapump that write the file once a day at 03AM but in this same filesystem the /backup/rman generate the files hourly.

To get consistent backup of /backup/datapump nothing can be write in entire filesystem during the backup or only inside the desired directory?

This. As long as nothing modifies the files in /backup/datapump during snapshot-less backup it's all good.

Thanks!

Thank you! While the engineer is reviewing the case, please tell if you're using linux default iscsi initiator for connection to the device, or something else?

Thanks!

Neither I can remember any reason for VAL to not work with multipath devices, nor I recall that limitation being in system requirements. The only known limitation for mpath is related to certain EMC configs which is clearly not your case. Let me check with both support and development teams internally,

Thanks!

The answer was:

When we enumerate disks by disk ID, mpath devices show multiple drives with the same drive ID. This is not something which the software can deal with. Therefor, the devices are skipped.

Currently, only DM-multipath devices are supported as per the following KB:

It seems that there was a miscommunication between you and the engineer. I've contacted the support team and Tier 2 engineer is on his way to escalate your case to T2, please keep working with them.

Thanks!

Hello Tide!

After some checks the engineer discover that the version 2 of VAL work fines and there an issue with the version 3. He collected a lot of logs and now we are running the backups with the snapshot-less mode.
Thanks a lot!
