How to recover from a broken zsys state with ZFS?

cn flag

A while back, I run into an issue where there were too many snapshots and zsys couldn't cope anymore.

I didn't know about the zsysctl suite of commands, so I manually deleted some snapshots. This, however, confused zsys and now I have this huge clone in my history upon which the current filesystem is based that seemingly references every file I've ever written and deleted.

I have to fix this because even though I have about 400GB of actual data only on my 1TB SSD, it's 86% full with only 125GB free.

I tried deleting with zsysctl state remove ... but I get an error ERROR couldn't remove user state rpool/ROOT/ubuntu_uyv8gh@autozsys_yu0btn: Couldn't find state: no matching state for rpool/ROOT/ubuntu_uyv8gh@autozsys_yu0btn.

Then I tried zsysctl state remove --system ... and this did... something. It kept my CPU moderately busy for 18h straight hours before I stopped the command and rebooted with seemingly no changes as a result.

I also tried removing zsys with apt remove zsys and then to make a snapshot of rpool, clone it, promote it, then delete anything before that clone. That didn't work because whatever clone I had created with zfs clone is not a clone apparently.

I don't want to reinstall this machine, it would be too much work and too much time. I want to get rid of the mess so that the old data is deleted and I can reclaim the missing space.

Alternatively, I'm also happy to switch to ext4 entirely on the root partition if there is a sane way to migrate my installation over so I don't have to reconfigure everything.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
