Hezký den,

nepotkal jste se někdo s problémem s mountem, resp. s
neexistujícím /dev/sdbX pro partition, kterou chci
mountovat?

Vyměnil jsem rootfs disk, protože odešel... dal sem tam
novou minimální instalaci ubuntu 18 LTS a ne a ne.

# dmesg | grep sdb

Podle toho to vypadá, že ta partition existuje, stejně tak
fdisk:

# fdisk -l /dev/sdb

Disk /dev/sdb: 7.3 TiB, 8001563222016 bytes, 15628053168

Podpora btrfs v jádře je, přidal jsem ho i do initrd. Ale
stejně nechápu, proč tam to sdb1 není, když ho driver vidí.
