Disk crash

Posted 12 months ago by Edelweiss🏔️

I was using a raid system but swapped out a another disk and re-added it (quickly). DO NOT DO that!
Just an update. I am currently re-indexing the chain. My Lightning directory does seem intact but as a test I used chantools to compact the channel db file and it failed.... If everything fails, I plan on re-starting and opening channels to all nodes that were working well a couple of days ago
Was using LND 0.18.5

Are you trying to say you performed a hot swap?

No I 're-added' a disk which was previously used on the system but had been used in another raid system in the mean time. The procedure to add a disk which was used in another raid system should include a wipeefs -a and zerosuperblock on the partition before addition. To be really safe add a sfdisk command to issue new IDs to the partition you are adding as well. This all happened because I started running a second node to combat the Bitcoin Core v30 attack. That is an attack as it undermines the centralization of bitcoin. Run Knots folks!
