Explorer for Oracle fails to restore. Mount issue with LVM

Post by stuartmacgreen »

Support case ID: 01900942

First attempt at restoring Oracle database using Veeam 9 U2 and fails at the Mounting stage. Using "Restore to latest state to" source VM the backup was taken.

VM Guest OS: SUSE Linux Enterprise 11 SP4 (64bit)
Oracle: 11.2.0.4.0 - Enterprise 64BIT PRODUCTION
Oracle Database is stored on LVM Volumes within the Linux OS.
It is not Oracle ASM

Backup is successful every time. Just database backups no transaction logging taking place.

VEfO dialog throws this message:
Agent failed to process method {Mount.GenericMount}

Invalid shift offset: [62272831488]. Device size: [53686894592]
Digging deeper into logs shows that it enumerates disks , partitions and LVM Volume Groups from the backup files. Then just states it fails.

Reaching out to anyone come across problems or sticking issues they got resolved. Can't fathom whats going on.


The target VM for the restore is the source of the backup.

On this VM the contents of the log file detail the issue
/var/log/VeeamBackup/Agent.MountHost.log_cli.log

Code: Select all

Re: Explorer for Oracle fails to restore. Mount issue with L

Post by Mike Resseler »

Hey,

I'm no expert in Oracle but what I do see is that you are using SUSE 11 with Oracle 11 and according to our release notes we only support SUSE 12 WITH oracle 12 so this might be an issue. (https://www.veeam.com/pdf/release_notes ... tes_en.pdf) However, since you already have a support case, let's wait what support have to say

Please keep this thread updated

Many thanks
Mike
