-* Operational Changes Log - -Deliberate, non-default config changes applied to mybitch (so they can be found and reverted later). Most recent first. - -** 2026-05-12 — amdgpu.mes=0 added (escalation of the MES-hang freeze mitigation) - -The 2026-05-11 =amdgpu.cwsr_enable=0= mitigation didn't reduce the iGPU "MES failed to respond" errors (14 hits in 14.5h after the fix vs. 38 over 10 days before — rate went *up*), so escalated per the documented path: added =amdgpu.mes=0= to =GRUB_CMDLINE_LINUX_DEFAULT= in =/etc/default/grub= (now =quiet splash amdgpu.cwsr_enable=0 amdgpu.mes=0=). Backup: =/etc/default/grub.bak-2026-05-12-amdgpu-mes=. =update-grub= run; param verified in all 6 =/boot/grub/grub.cfg= entries. Takes effect on next reboot (planned for after the in-progress first rsyncshot backup). =amdgpu.mes=0= disables the GFX11 hardware MES scheduler and falls back to the legacy KIQ path — sidesteps the hanging MES firmware entirely. Tradeoff: KIQ-on-GFX11 is a less-traveled config (small chance of cosmetic display/modeset quirks); irrelevant for Christine's light desktop workload. =cwsr_enable=0= kept (harmless alongside mes=0). *Revert:* restore =/etc/default/grub.bak-2026-05-12-amdgpu-mes= (or sed out = amdgpu.mes=0=), =update-grub=, reboot. After the reboot, check =journalctl -k -b | grep -c 'MES failed'= → should be 0. See the 2026-05-11 entry in =.ai/project-workflows/system-health-check.org='s Known Issues Log for the full background. - -** 2026-05-12 — rsyncshot backups + travel keep-awake mode - -Set up the same =rsyncshot= → TrueNAS backup mybitch's siblings use, and made mybitch never suspend so backups keep running while Christine travels with it. - -*** rsyncshot install (mirrors ratio's setup) -- =/usr/local/bin/rsyncshot= — the script (source of truth: =~/code/rsyncshot/rsyncshot=). -- =/etc/rsyncshot/config= — =REMOTE_HOST="cjennings@truenas.tailf3bb8c.ts.net"=, =REMOTE_PATH="/mnt/vault/backups"=, =SSH_IDENTITY_FILE="/root/.ssh/id_ed25519"=. (See "destination pinned to Tailscale" below for why the full MagicDNS name.) -- =/etc/rsyncshot/include.txt= — =/home /etc /usr/local/bin=. =/etc/rsyncshot/exclude.txt= — copied verbatim from ratio. -- =/etc/logrotate.d/rsyncshot= — copied verbatim from ratio. =/var/log/rsyncshot.log= — the log. -- Root crontab: hourly at :30 (hours 0-1,3-23, keep 23) + daily at 2:30 (keep 30), each wrapped in =flock -x /tmp/rsyncshot.lock=. Identical to ratio's schedule. -- =/root/.ssh/id_ed25519= (+ =.pub=) — new keypair generated on mybitch, no passphrase, comment =root@mybitch-rsyncshot=. mybitch's =cjennings= account had no outbound key (it's a receive-only account), so the backup runs with a dedicated root key instead. The pubkey was appended to =~cjennings/.ssh/authorized_keys= on TrueNAS (the line tagged =root@mybitch-rsyncshot=). -- =/root/.ssh/config= — =Host truenas truenas.tailf3bb8c.ts.net 100.67.22.65= → =User cjennings=, that IdentityFile, =ServerAliveInterval 60 / ServerAliveCountMax 10 / TCPKeepAlive yes=. Host keys for those names added to =/root/.ssh/known_hosts=. -- TrueNAS side: =/mnt/vault/backups/mybitch/= directory created, owned =cjennings:cjennings= (=vault/backups= is a ZFS dataset; per-host backups are just subdirectories, like =ratio/= and =velox/=). -- *Revert:* =sudo crontab -r= (or remove the rsyncshot lines), =sudo rm -rf /usr/local/bin/rsyncshot /etc/rsyncshot /etc/logrotate.d/rsyncshot /var/log/rsyncshot.log /root/.ssh/id_ed25519* /root/.ssh/config=, restore =/root/.ssh/known_hosts= if desired, remove the =root@mybitch-rsyncshot= line from =~cjennings/.ssh/authorized_keys= on TrueNAS, and =rm -rf /mnt/vault/backups/mybitch= on TrueNAS. - -*** destination pinned to Tailscale -=REMOTE_HOST= uses the full Tailscale MagicDNS name =truenas.tailf3bb8c.ts.net= (not the bare =truenas=) so the backup always routes over the tailnet regardless of what a hotel/away-from-home router's DNS resolves =truenas= to. Tailscale uses a direct LAN path between same-LAN peers, so this is near-zero perf cost when mybitch is on the home network. *Revert:* set =REMOTE_HOST="cjennings@truenas"= in =/etc/rsyncshot/config=. - -*** keep-awake (never suspend) — three layers -1. =systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target= — the hard guarantee; suspend can't happen even if requested. *Revert:* =sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target=. -2. Cinnamon power gsettings for user =cciarm= set to ='nothing'=: =sleep-inactive-ac-type=, =sleep-inactive-battery-type=, =lid-close-ac-action=, =lid-close-battery-action= (schema =org.cinnamon.settings-daemon.plugins.power=). Were ='suspend'/'suspend'/'nothing'/'suspend'=. *Revert:* set them back, or run =gsettings reset= on each key as =cciarm=. -3. =/etc/systemd/logind.conf.d/no-suspend-keep-awake.conf= — =HandleLidSwitch=ignore=, =HandleLidSwitchExternalPower=ignore=, =HandleLidSwitchDocked=ignore=, =IdleAction=ignore=. (Written but not applied live — =systemd-logind= wasn't restarted because sessions were active; takes effect on next reboot. Layers 1-2 cover the gap.) *Revert:* =sudo rm /etc/systemd/logind.conf.d/no-suspend-keep-awake.conf= then reboot or =systemctl restart systemd-logind=. - -When mybitch goes back to being a stationary machine (or this whole arrangement is no longer wanted), reverse layers 1-3. The rsyncshot backup itself is worth keeping regardless. - -*** IPv6 set to link-local-only (fixes the tailscale dropout) -mybitch dropped off the Tailscale tailnet on 2026-05-12 AM. Root cause: the home WiFi ("dupre") has device(s) advertising ULA-only IPv6 RAs (prefixes =fdc4:c4c6:3fb0:16cc::/64= and =fd67:8615:6780:1::/64=) with no default route. NetworkManager (=ipv6.method=auto=) SLAAC'd a "global"-scope ULA address onto wlp5s0 with no v6 internet path, so tailscaled kept trying IPv6 to controlplane/DERP, failed "network is unreachable", flapped, and lost its control connection. mybitch has no working global IPv6 anywhere (no ISP v6), so the fix is to ignore underlay v6: -- =/etc/NetworkManager/conf.d/ipv6-link-local-only.conf= → =[connection] ipv6.method=link-local= (connection default — covers home WiFi, travel WiFi, phone hotspot). -- =nmcli con modify dupre ipv6.method link-local= (explicit on the home connection). -- Effect: wlp5s0 keeps only fe80:: (mDNS still works), no SLAAC, no v6 routes; tailscale0's overlay v6 untouched; tailscaled uses the IPv4 underlay. Activates on reboot or =nmcli dev reapply wlp5s0=. -- *Revert if mybitch ever gets real IPv6:* =sudo rm /etc/NetworkManager/conf.d/ipv6-link-local-only.conf=; =sudo nmcli con modify dupre ipv6.method auto=; reboot or =nmcli dev reapply wlp5s0=. - -*** caveats (relayed to Craig for Christine) -- mybitch must stay plugged into AC for backups to keep running — masking suspend doesn't stop a battery dying with the lid closed. -- mybitch must be on WiFi at the destination and stay on the Tailscale tailnet. |
