Hello Just let's repeat. Full thin-pool is NOT in any way comparable to full filesystem. Full filesystem has ALWAYS room for its metadata - it's not pretending it's bigger - it has 'finite' space and expect this space to just BE there. Now when you have thin-pool - it cause quite a lot of trouble across number of layers. There are solvable and being fixed. But as the rule #1 still applies - do not run your thin-pool out of space - it will not always heal easily without losing date - there is not a simple straighforward way how to fix it (especially when user cannot ADD any new space he promised to have) So monitoring pool and taking action ahead in time is always superior solution to any later postmortem systems restores.
Yes that's what I said. If your thin pool runs out, your system will crash.
Thanks for alluding that this will also happen if a thin snapshot causes this (obviously).
