Centos/nagiosxi migration 7

[sharding]

hours to complete, I did not know that, there was no warning in the migration document, maybe it was working, I'll try the first one again overnight

sounds good. It also take a ton of disk space to complete, extracting the rrd files into something that can be migrated can take a TON of disk space.

the first one ran, it created a 2 GB perfdata file, that's nothing we have over 30 GB free, the new server has over 200 GB free !

Ya, it can just take more than that while creating it. Some people try to make the file when they have virtually no space available

so first restore, it looked like it was working fine then a whole bunch of folders gave this error

does that mean it couldn't overwrite or there was no data to replace? or what should I do here?

[scottwilkerson]

These files were likely updated while you were performing the data transfer

If they are still showing performance data you should be fine.

Otherwise you may need to stop nagios for a few minutes while you perform the restore.

[sharding]

ok what's the nagios stop and start cmd ?

[scottwilkerson]

ok what's the nagios stop and start cmd ?

Code: Select all

systemctl stop nagios

and

Code: Select all

systemctl start nagios

seeing same errors, if this is only graph data, I think we'll move on here, not the end of the world, I am going to do some testing then I will need to shutdown the old 32 bit live server, put ip into new 64 bit server then bring up and allow everything to check back in.

(we use the nagios++ client to only talk to the live address so tons show as issues on a temp ip)

Yes it is only graph data
