Independent disk error about ghettovcb HOT 7 CLOSED

I just tested this scenario and I get the following when I have a VM with independent disk:

Final status: WARNING: All VMs backed up, but some disk(s) failed!

Can you provide a bit more details on the VM? Does it only have independent disks or does it contain regular disks? Are you trying to backup a single VM or are there others?

This is weird,
I've just (after these 3 days since i've posted this issue) re-checked log files of scheduled backups - one definition contains 3 VM's, one of which has independent disk. Log file shows WARNING (the exact one you've posted), not an ERROR.
No idea where it came from earlier (output posted in the first post was copy-pasted and the error did happen, really).

Seems like I've wasted some of your time - really sorry for that.
However I'll keep an eye on this and get back in touch if it re-occurs.

Big thanks for concern and once again sorry for the "false-positive".

No worries. Glad it's working for you

Hi,
I'm expecting the same problem, installed 2 days ago downloading from zip package.

the report email has error statement in object:
ghettoVCB - esx2 ###### Final status: ERROR: No VMs backed up! ######

and both, WARN adn ERR in body:
013-04-05 10:07:16 -- info: Backup Duration: 1.82 Minutes
2013-04-05 10:07:16 -- info: WARN: Formica has some Independent VMDKs that can not be backed up!

2013-04-05 10:07:22 -- info: ###### Final status: ERROR: No VMs backed up! ######

do you have suggestions ?

from ghettovcb.

i'm trying to debug this by myself:

first thing i found is the getFinalStatus function, i exit on the last IF statement :
[[ $VM_OK == 0 ]]
with status: ###### Final status: ERROR: No VMs backed up! ######"

while i am expecting to exit from the 3rd IF statement:

[[ $VM_OK == 1 ]] && [[ $VM_FAILED == 0 ]] && [[ $VMDK_FAILED == 1 ]]
with status: ###### Final status: WARNING: All VMs backed up, but some disk(s) failed! ######

    #added by me for testing ...
logger "info" "debug getFinalStatus last ELIF: vm_ok ${VM_OK}\n";
logger "info" "debug getFinalStatus last ELIF: vm_failed ${VM_FAILED}\n";
logger "info" "debug getFinalStatus last ELIF: vmdk_failed ${VMDK_FAILED}\n"; 

and the output is:
2013-04-05 13:42:13 -- info: debug getFinalStatus last ELIF: vm_ok 0
2013-04-05 13:42:13 -- info: debug getFinalStatus last ELIF: vm_failed 0
2013-04-05 13:42:13 -- info: debug getFinalStatus last ELIF: vmdk_failed 1

0 0 1 while i need a 1 0 1 to exit with the correct status.
now i'm going to check where the VM_OK is going to be setted as 1,
maybe this is happening only after a FULL success of at least one virtual machine, success that i never meet because i'm using the script with the "-m vmName" param. to backup a single vm.

i'll post again after some tests.

ok, it seems to me (IMHO) that the problem is exactly this one: at least one VM have to complete a successful backup without having indipendent disk WARNs or something else.

So if all your VMs will fall into one of this conditions:

[[ ${SNAP_SUCCESS} -ne 1 ]]
[[ ${VM_VMDK_FAILED} -ne 0 ]]
[[ ${VM_HAS_INDEPENDENT_DISKS} -eq 1 ]]

VM_OK value will be never set to 1 because this will happend after the ELSE.

this could be fine for the first 2 conditions because they are errors preventing the backup to be done, but the 3rd one is just a warning so it should be moved after the ELSE letting the VM_OK take the 1 value because i do have a working backup of at least one VM.

just my 2 cents ... let me know if i'm wrong.

Marco.
sorry for my poor english.

from ghettovcb.

i've moved the IF VM_HAS_INDEPENDENT_DISKS after the ELSE and it works now.
please report me if i've missed some side effects requiring that condition to be on its original place

i've also deleted the "create simlink for rsync" section inside that IF as it will be already executed (already written) just after the ELSE.
