Re: Zenoss 2.4.5 doesn't restore Zenpack

in this new installation i also found that zenperfwmi doesn't exist...

on old server:

[root@IpMonitoring bin]# ls | grep zenperf
zenperfsnmp
zenperfwmi

on new server:

[zenoss@ZenossXen bin]$ ls | grep zenperf
zenperfsnmp

... so bad....

Re: Zenoss 2.4.5 doesn't restore Zenpack

There is a ticket http://dev.zenoss.org/trac/ticket/5180

And if you look at the options for zenrestore you should find the --zenpacks options

Though officially you have to re-install the zenpacks to do a restore. The reason is that zenpacks can and do all sorts things that are unanticipated. So the zenpack restore may or may not work depending on what the zenpack installed on the file system that is why it is always better to re-install the zenpack if possible

From the Admin Guide...

#4.2.1. Before You Restore

Before you can restore your Zenoss instance, you must ensure that the same ZenPacks that were installed on the backup system are also installed on the target system.

Products.ZenModel.ZenPack

This pack is missing or broken. You may need to restart Zope.

this error persist after installing core zenpack and restarting zenoss

Re: Zenoss 2.4.5 doesn't restore Zenpack

Perf data bug has been fixed; that ticket, 5315, had a reference to http://dev.zenoss.org/trac/ticket/5447

In the meantime the perf data should be in the backup tar, it just had the wrong directory information associated with it. Look at the note in the ticket I linked to, should tell you were to find the perf data

Re: Zenoss 2.4.5 doesn't restore Zenpack

zenrestore does have a --zenpacks option. However it may or may not work with all zenpacks. The 2.4.5 version of zenrestore doesn't restore the bin symlinks for zenpack daemons, the 2.5 version will.

Re: Zenoss 2.4.5 doesn't restore Zenpack

thanks, i think the important thing is that zenbackup works well, if zenrestore need some quick fix is not a big problem now, i hope it will be fixed in future but with previous cheats and hints i can recover all my data

Re: Zenoss 2.4.5 doesn't restore Zenpack

--zenpacks            Experimental: Restore any ZenPacks in the backup. Some
                        ZenPacks may not work properly. Reinstall ZenPacks if
                        possible

i see that it's till experimental..

i see that also in 2.5.1 zenpacks are not restored by default but i think it's not correct because when i have a backup with zenpack and i restore without zenpack i have a lot of issue due to zenpack missing (portlet, wmi...)
