[knot-dns-users] zone lost its KSK

Hello, today I had a long power outage that stopped my primary server for a dozen hours When I re-started the server, some zones refused to start : Feb 12 21:55:17 arrakeen knotd[20728]: info: [geekwu.org.] DNSSEC, signing zone Feb 12 21:55:17 arrakeen knotd[20728]: error: [geekwu.org.] zone event 're-sign' failed (invalid parameter) the invalid parameter was there was no active KSK for these zones, as a keymgr list show b37b6c2[...] 39945 KSK ECDSAP384SHA384 publish=1636966605 active=1637053005 7cc8622[...] 20799 ZSK ECDSAP384SHA384 created=1706695010 After manually setting published & active status in keygmr, reloading these zones succeeded, and knot restarted to serve them. Do you know how these zone could has failed as this ? They run fine on auto-sign for years now. should I monitor closely the ones that need a re-sign tomorrow ? Regards, -- Bastien
