Hi all,

we did a new setup of our OnCommand Server on a new hardware. Database and performance data resides on LUN that we used again. Since two days our backup fails with the following error

Jan 09 22:00:17 [dfm:ERROR]: [3994:0x7fba67c646f0]: Could not get size of performance archive directory /om-perfdata. Please make sure this directory exists.

Jan 09 22:00:17 [dfm:ERROR]: [3994:0x7fba67c646f0]: Could not get size of performance archive directory /om-perfdata. Please make sure this directory exists.

Jan 09 22:00:17 [dfm:ERROR]: [3994:0x7fba67c646f0]: Database backup create failed

Jan 10 22:00:04 [dfm:ERROR]: [28425:0x7ffe3ff3f6f0]: Could not get size of performance archive directory /om-perfdata. Please make sure this directory exists.

Jan 10 22:00:04 [dfm:ERROR]: [28425:0x7ffe3ff3f6f0]: Could not get size of performance archive directory /om-perfdata. Please make sure this directory exists.

The directory exists and I can get the size with the df command on the linux host

v100spldv02:/opt/NTAPdfm/log # df -m /om-perfdata

Filesystem           1M-blocks      Used Available Use% Mounted on

/dev/dm-3               515054    181826    307065  38% /om-perfdata

Any hints are appreciated. Thanks in advance.

Hi Stefan,

does any of the following apply:

- OnCommand 5

- DFM DB and/or Perf Data stored in a directory different from the default

- DFM DB and Perf Data reside on additional LUN

- SnapShot-based backup via SnapDrive

Could be BURT 560602

regards, Niels

It seems the issue is a bit different from the above bug. dfm about shows the right location for the perfdata. However dfm backup diag shows an error.

This is a perfect signature of the bug. Pls add your case. Also can you get the output of dfm options list | grep -i perf

Is there any workaround to get the backup back running? I will create the case now und let you know the case no.

Hi again,

is there any workaround to get the backup back running? Currently we have no database backup.

Thanks in advance

skellner

I figured out a workaround for the database backup.

stop dfm services

start sql service

Copy perfdata back to local drive

change option perfarchivedir back to local drive

start dfm services

dfm backup create

After that you can copy the perfdata back to the Lun and the database backup keeps working.
