Comment:

 I didn't see anything out of the ordinary.  gitea's git folder is taking
 up 66GB and /var/www/svn takes up about 25GB.  Those are the biggest
 eaters of disk space.  Followed by /var/log which is about 2.5GB

 So I assume it's just churn of data.  I looked at the snapshots which the
 500GB I had allocated was partly used for.  I deleted a couple more
 snapshots and upped the capacity from 400G to 700GB. using


 {{{
 lxc config edit tracsvn
 }}}


 So now there is 241G available.


 Command to check snapshot usage is below for future reference

 {{{
  zfs list -t snapshot | grep tracsvn
 }}}

 The snapshot sizes are averaging anywhere from 2GB - 19 GB and we have a
 retention of 30 days.
 as shown below

 So worsed case 30*20 = 600Gb for snapshot and actual container is using
 110GB.  So we'd need 600 + 110GB = 710GB to handle worsed case scenario.
