Booted Linux and got greeted with THIS 😅 ext4 journal aborts, dm-* I/O errors, superblock write failures Thought the disk was cooked Turns out: HDMI plugged into a TV during boot → Intel iGPU hiccup → brief NVMe stall → ext4 panic SMART is clean. Disk is healthy.

数年間使っていて、初めてデフラグ(s4defrag)をした、ラズパイファイルサーバ(8TB)。 ２日間かかって終わった。 ext4でも断片化(fragmented)率は27%に及ぶんだな。
