dm-integrity Finds the Bad Block; To Fix It, It Wants a Mirror
I flipped one byte on a writable disk and watched dm-integrity: errno 84, the journal writing twice, a relocated block getting caught, and LVM RAID1 healing the bad leg on its own.

dm-integrity Bozuk Bloğu Bulur, Düzeltmek İçin Bir Ayna İster
Yazılabilir diskte tek baytı çevirip dm-integrity'nin ne yaptığına baktım: errno 84, journal'ın iki kat yazması, taşınan bloğun yakalanması ve LVM RAID1'in bozuk bacağı kendi kendine onarması.

Bir Bit Çevirdim, dm-verity 35816. Blokta Durdu
1 GiB'lık imajda tek biti çevirip kernel'in nerede durduğunu izledim: hangi blok okunamaz oldu, önbellek neyi sakladı, hash ağacındaki bir bit kaç bloğu götürdü, Ubuntu'nun FEC'i neden yok.

I Flipped One Bit and dm-verity Stopped at Block 35816
One flipped bit in a 1 GiB image, watched from the kernel's side: which block became unreadable, what the page cache hid, how many blocks one bit in the hash tree took down, and why Ubuntu has no FEC.

rmp-ostree is all well and good until you have to do some kind of devicemapper thin-wrapping bullshit and now I’m reduced to installing packages one at a time and rebooting like it’s the 1960s or something

Does anybody use docker service on guix system? I'm getting

"[graphdriver] prior storage driver devicemapper failed: devicemapper: Error running deviceCreate (CreatePool) dm_task_run failed"

and the daemon won't start :(
