We very quickly determined that it was a bug in the Steam client and found out that this is a known issue:\r\n\r\nhttps://github.com/ValveSoftware/steam-for-linux/issues/4982\r\n\r\nPeople are currently working around this by setting quotas. In the issue, I suggested that a LD_PRELOAD shim could workaround it. However, it occurs to me that we could add a specific workaround to ZFS to truncate free space (and maybe also used space) to make software that does such stupid things happy. I am not sure how I feel about that. I'd be perfectly happy to say \"use quotas\" and let that be the end of it, but I thought it merited some minor discussion.\r\n\r\nDoes anyone think we should add a workaround for compatibility with broken software? I am leaning toward just telling users to use quotas. A fair number of users appear to be affected, so maybe we could document this in a FAQ entry."},"comment":{"url":"https://api.github.com/repos/zfsonlinux/zfs/issues/comments/422994178","html_url":"https://github.com/zfsonlinux/zfs/issues/7927#issuecomment-422994178","issue_url":"https://api.github.com/repos/zfsonlinux/zfs/issues/7927","id":422994178,"node_id":"MDEyOklzc3VlQ29tbWVudDQyMjk5NDE3OA==","user":{"login":"ryao","id":1386373,"node_id":"MDQ6VXNlcjEzODYzNzM=","avatar_url":"https://avatars2.githubusercontent.com/u/1386373?v=4","gravatar_id":"","url":"https://api.github.com/users/ryao","html_url":"https://github.com/ryao","followers_url":"https://api.github.com/users/ryao/followers","following_url":"https://api.github.com/users/ryao/following{/other_user}","gists_url":"https://api.github.com/users/ryao/gists{/gist_id}","starred_url":"https://api.github.com/users/ryao/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ryao/subscriptions","organizations_url":"https://api.github.com/users/ryao/orgs","repos_url":"https://api.github.com/users/ryao/repos","events_url":"https://api.github.com/users/ryao/events{/privacy}","received_events_url":"https://api.github.com/users/ryao/received_events","type":"User","site_admin":false},"created_at":"2018-09-19T23:48:31Z","updated_at":"2018-09-19T23:48:31Z","author_association":"MEMBER","body":"@GregorKopka My doctor told me to use VR to get more exercise.
