Summary
An Advanced Recovery Open Storage (AROS) or Advanced Recovery SnapVault (ARSV) backup fails on an Oracle instance and reports a problem finding file system information. To resolve this issue, change the location of the instance to reside under a logical volume manager (LVM).
Symptoms
Performing an AROS or ARSV backup on an Oracle instance fails with the following error message in the job log: "Problem in finding file system info for logdev".
The job log displays:
172.16.2.19 10/6/2010 2:16:20 pm SNBAPH_331J prepare for snap operation for the VV
(/ORACLE/10g/vmfg) is complete.

Resolution
To resolve this issue, ensure that the instance resides under a logical volume manager (LVM).
In this case, the /oracle instance is on ext3, a supported file system. However, /dev/sda3 is mapped to /oracle, which is not under an LVM.
