<p><span class="h-card" translate="no"><a href="https://mastodon.social/@dramforever" class="u-url mention">@<span>dramforever</span></a></span> i just checked and i can convert my existing LV to a thin one on the fly. my one concern is that corruption of the thin metadata volume might cause extremely severe data loss</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> i found some anecdote that &quot;thin-provisioned LVM snapshots&quot; work well. i don&#39;t know if you can smoothly start using this</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> I think what worries me is that any intentional semantics for having a *specific known thing* happen when you edit a list mid-execution would both require amount of added complexity in the language spec to challenge the claim this is a &quot;simple&quot; language, and also might put awkward long-term restrictions on the implementation.</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@dramforever" class="u-url mention">@<span>dramforever</span></a></span> oh this is a fantastic idea. lvm should be able to do it and i already use it</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@mcc" class="u-url mention">@<span>mcc</span></a></span> you could use (1) to implement hot reload, erlang style but infinitely more cursed!</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> I know, sorry. You&#39;ll be ready for next time!</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> even for things with no back up, i personally run 15-minutely btrbk btrfs snapshots with decaying retention for earlier files. snapshots like these take minimal time to create and help with being able to create backup in a more consistent state</p><p>i will probably switch to zfs for my next computer/drive, whichever comes first, but the principle is the same.</p><p>ofc this depends on fs support. i&#39;m not aware if lvm is capable of doing this on a block dev but it sounds sketchy</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@purpleidea" class="u-url mention">@<span>purpleidea</span></a></span> ... good idea, but would not help me here</p>
