I have a bit of a mystery here, and I am hoping someone can help me solve it. I have two machines, one is my desktop, with two mirrored ZFS pools. The other is my laptop has a single stripe across two SSDs. Both are running 13.2-RELEASE with zfstools, and have been since shortly after they were built in 2019. I have both configured identically:
Which should give me 4 frequent (quarter-hourly), 24 hourly, 7 daily, 4 weekly, and 12 monthly snapshots, which is exactly what I want. But for some reason, I see that I only have two monthlies on my desktop, yet I have the full 12 on the laptop, and I am trying to figure out why that would be. Here is what I have (for /usr/home) on the desktop:
But on the laptop:
I should note that all of the frequent, hourly, and daily snapshots appear to be intact on defiant. It is just that every monthly before May 1 is gone.
So I was wondering where I could look to try and figure out why I only have two months of snapshots on defiant, and a full year on danube. I checked the logs and nothing jumped out at me. I also made a point of checking my command history to make sure I had not done something dumb, and don't see anything there either.
Thanks,
