But what could be increasing the size of the snapshot after it was 
created? Right now, yesterday's snapshot made at 14:45 UTC (nearly 22 
hours ago) has grown to 468MB:

 	root@clustor2:~ # date
 	Sat Jan 11 10:31:05 GMT 2025
 	root@clustor2:~ # zfs list -t snapshot
 	NAME                              USED  AVAIL  REFER  MOUNTPOINT
 	clustor2/ma@2025-01-10_14.45.00   468M      -  3.09T  -

It's true the size this file system reported by 'zfs list' has increasesd 
from 3.09TB yesterday to 3.10TB now (it's used for storing user data in an 
HPC that currently has about 700 jobs running on it) but it's very strange 
that a snapshot supposedly "set in stone" at the time it is created should 
continue to grow afterwards!
