Icinga2 - change location of replay log

Icinga 2
1

Description

Hi, I’m running an icinga2 HA cluster master zone, and when one of the master nodes dies, (i.e OOM Kill) , the other master node stores the replay log on the documented location:

/var/lib/icinga2/api/log

since available space on ‘/’ partition of each one of my “icinga2 master” nodes barely enough to cover 25 minutes of downtime, I was wondering if there is a way to configure the application to use a different path for the replication logs?

i.e. /MyVeryLargePartigion

I know that I can (and probably will) mount a LVM partition under /var/lib/icinga2/api/logs , but wanted to save some time in reconfiguring the filesystem shall this software change be supported ?

/dev/vda1 8.0G 4.4G 3.7G 55% /
/dev/mapper/VolGroup01Logs_volume 12G 1.6G 9.6G 15% /customlogs

why dont you mount a different partition with enough space over /var/lib/icinga2/api/log ?

You could create a symlink from /var/lib/icinga2/api/log to anywhere in your
filesystem which has sufficient space, if you don’t want to mount a new partition
there.

I just wanted to confirm if this was a parameter that could be configured somewhere else, like .ie. on systemd defaults file, hence avoiding most of administrative load for reconfiguring the puppet/volumes/partitions, etc.
as last resource, yes, mounting or symlinks can be made
