03:05 < HelloShitty> Hi
03:05 < HelloShitty> After a few days with my lightning node off due to a database problem in my bitcoin node, I see that one of my channels was closed
03:06 < HelloShitty> How can I see if I lost any funds from that channel?

03:54 < darosior> HelloShitty: if it was less than 100 blocks ago you can `listpeers <peer id>` you'll see why the channel was closed
03:55 < darosior> Probably an unilateral close on their end, you would not have lost funds (apart the tx fees if you were the funder)

04:20 < HelloShitty> ok, will check
04:21 < HelloShitty> In list peers I can only see the 2 open channels
04:21 < HelloShitty> My Lightning Node was off for like 4 days while my bitcoin database was synching
04:22 < HelloShitty> so, at an average of 1 block per 10 mins
04:23 < HelloShitty> that's roughly 3600 * 24 / 10 blocks
04:23 < HelloShitty> no
04:23 < darosior> Then listfunds ?
04:24 < HelloShitty> darosior: so all the addresses that shows up in that command, are all in my control?
04:25 -!- cryptosoap [~cryptosoa@gateway/tor-sasl/cryptosoap] has quit [Ping timeout: 240 seconds]
04:25 < HelloShitty> Can I just take each address funds and send them somewhere else?
04:27 < darosior> yeah
04:28 < HelloShitty> So, in this command, the funds that are locked in open channels don't show up, right?
04:28 < darosior> Also consider increasing your --watchtime-blocks config if you are likely to have 4-days-long outages
04:29 < darosior> Ok -- sorry i meant listfunds "outputs" entry..
04:31 < HelloShitty> I hope this was a one time ocasion
04:31 < HelloShitty> this was a bitcoin database corruption
04:32 < HelloShitty> and I ended up restarting the bitcoin node with --reindex
04:32 < HelloShitty> which started reindexing the entire blockchain
04:32 < HelloShitty> and it took around 4 days
04:32 < HelloShitty> I need to check for that setting watchtime-blocks
04:32 < HelloShitty> never heard of it
04:34 -!- mryandao [~mryandao@gateway/tor-sasl/mryandao] has quit [Ping timeout: 240 seconds]
04:34 < HelloShitty> darosior: does that option shows up in lightning-cli help ?
04:34 < darosior> Next time, try with --reindex-chainstate first it's significantly faster ;) (and it's likely your corruption was only the chainstate not the blk index)
04:34 < darosior> Yeah, or `man lightningd-config`
04:35 < darosior> As usual you also have everything up there https://lightning.readthedocs.io/ :)
04:35 < darosior> https://lightning.readthedocs.io/lightningd-config.5.html search for watchtime here
04:35 < HelloShitty> yes, but by the time I issued the command I forgot about that the faster command was the one you mentioned
04:35 < HelloShitty> so I was at a no turning back point
04:36 < darosior> Anyways it's basically the CSV you are imposing to your peer
04:36 < HelloShitty> the chainstate command?
04:37 < HelloShitty> s/command/option
04:37 < darosior> So it's a tradeoff. Increasing it is conservative (funds may be locked for longer, but you have more time in case of an outage before starting to sweat :p)
04:37 < darosior> No the watchtime one
04:37 < darosior> The option you asked about
04:37 < HelloShitty> ahh ok
04:37 < HelloShitty> I'll read about it after lunch
04:37 < HelloShitty> thanks
04:37 < darosior> (It's 144 -- 1day by default)

04:53 < nibbier> I guess one could use another bitcoin node temporarily, if your main node goes down. Just need someone to offer RPC access? I guess some trust is needed, but there would be no direct access to funds on either side (as long as bitcond does not hold a wallet?)

06:24 < HelloShitty> never understood when would that be needed
06:25 < HelloShitty> unless tat's used to access my lightning node features from some other compupter in another network

06:52 < HelloShitty> darosior: this cannot be good, can it?
06:52 < HelloShitty> "options": {
06:52 < HelloShitty>             "backup-destination": "null"
06:52 < HelloShitty>          }
06:52 < HelloShitty> this is from lightning-cli listconfigs
06:53 < HelloShitty> nibbier: my backup is now 1.7Gb
06:54 < darosior> that's probably from the backup plugin ? I don't know i never used it (yet).
07:07 < HelloShitty> darosior: yes
07:08 < HelloShitty> I need to be at least 70% sure I'm running my node with backup capabilities because I want to open a larger channel and I want to make the best I can to avoid losing funds if anything oes wrong
07:21 < nibbier> HelloShitty: I'm waiting the update for constant sub-GB backups... cdecker seemed confident on this. I guess it's all a matter of ressources. I'll recheck my size and restart...
07:22 < nibbier> and I'm not even on RAID, completeley reckless without backup :/
07:22 < nibbier> raid upgrade planned soon (tm)

16:10 < nibbier> HelloShitty: yes... either this or some clustered filesystem, but I assume just a raid is simpler and sufficient
