  • Как расширить раздел var в Linux (LVM encryption)?

    @ProForensic Автор вопроса
    Не совсем понятно, делать ли это все из live-окружения или непосредственно в системе? И как указать, что именно из Home нужно взять свободное место?

    lvdisplay выдает вот это:

    root@Ivanov:/home/serg# /sbin/lvdisplay
    File descriptor 46 (anon_inode:inotify) leaked on lvdisplay invocation. Parent PID 5398: bash

    @ProForensic Автор вопроса
    elbrus56, mayton2019, также я думаю, что файлы там все-таки есть, т.к. размер указан 1 ТБ, а не пустой:

  • Как восстановить пропавшие файлы на зашифрованном zfs датасете?

    @ProForensic Автор вопроса
    mayton2019, все возможно, но все-таки я надеюсь, что не такой криворукий. Было как-то странно, все работало, собственно оставил на майские работающий комп - приехал к неработающему.

    Смущает, что после переустановки этот датасет не подцепился к samba, т.е. незашифрованный при импорте образовал общий ресурс, как и раньше, а зашифрованный не образовал ничего.
    Я откопал памятку для себя, в которой писал, что и как я создавал. По ней получается, что еще один SSD был выделен по кэширующий.

    lsblk
    sudo ls -lh /dev/disk/by-id
    sudo zpool create -f -o ashift=12 -m /mnt/data pool1 wwn-0x5000039a78cafc43
    sudo zpool add pool1 cache nvme-eui.00000000000000000026b76853063e85
    sudo zfs set compression=lz4 pool1
    sudo zfs set xattr=sa pool1
    sudo zfs set relatime=on pool1
    sudo zpool status -v pool1
    sudo zfs create -o encryption=aes-256-gcm -o keylocation=prompt -o keyformat=passphrase -o pbkdf2iters=1553683 pool1/encdset1
    sudo zfs set sharesmb=on pool1/encdset1
    sudo chown -R serg:serg /mnt/data
