Vyskúšal som a budem sledovať ako sa to správa. Tiež mi napadlo, či nie je problém v nesprávnom rozdelení na subvolumes a následnými snapshotmi. Momentálne mám iba dve subvolume - @ pre / a @home pre /home. Snapshoty vytvára automaticky timeshift, hlavne pri práci s apt (timeshift-autosnap-apt). Možno je problém v tom, že na tých snapshotoch sú data, ktoré sa často menia (cache a pod.) a po ich zmene/vymazaní musí btrfs veľa upratovať. Mohli by ste mi poslať rozdelenie subvolume u vás? V /etc/fstab mám toto:
UUID=e9dc761d-68e1-455a-ad6b-26537b2e0f9b / btrfs defaults,subvol=@,ssd,noatime,space_cache,commit=120,compress=zstd 0 1 UUID=e9dc761d-68e1-455a-ad6b-26537b2e0f9b /home btrfs defaults,subvol=@home,ssd,noatime,space_cache,commit=120,compress=zstd 0 2
A snapshoty vyzerajú takto:
