Uz asi 2 hodiny hladam info ako mountnut fyzicky HDD do LXC.
Situacia je taka:
Proxmox bezi na SSD 120GB kde mam 1xKVM a 1xLXC (debian 9)
Dalej mam na SATA pripojeny 1x HDD 3TB (kde mam data)
Vypis z fdisk -l

Jedna sa o /dev/sdb
Je to vidiet aj na web klikatku

Skusil som ho do kontajnera pridat, ale nikde ho nevidim (asi nieco nerobim spravne)
lxc-device add -n 101 /dev/sdbNema niekto skusenosti ako pridat (mountnut) HDD do kontajnera ?
-
Už jsem to řešil taky. Musíš to udělat pomocí bind mount: https://pve.proxmox.com/wiki/Unprivileged_LXC_containers (https://pve.proxmox.com/wiki/Unprivileged_LXC_containers)
V GUI to zatím nenaklikáš, je nutné upravit konfigurák kontejneru.
-
Skusil som to podla toho navodu (https://forum.proxmox.com/threads/lxc-cannot-assign-a-block-device-to-container.23256/)
ls -al /dev/sdb
brw-rw---- 1 root disk 8, 16 May 17 2018 /dev/sdb
pridal som do konfiguraku kontajnera na koniec
nano /etc/pve/nodes/proxmox/lxc/100.conftieto 2 riadky
lxc.aa_profile = lxc-container-default-with-mounting
lxc.cgroup.devices.allow = b 8:16 rwm
a v kontajnery som spusil mknod
mknod -m 666 /dev/sdb b 8 16
mknod: /dev/sdb: File existschlapik uz v prvom prispevku pise, ze mu to funguje, ale po restarte to uz nefunguje.
Ako zistim, ci mam hdd pripojeny ?
mount /dev/sdb /media
mount: /dev/sdb is write-protected, mounting read-only
mount: cannot mount /dev/sdb read-only
Poznamka:
Momentalne skusam pripojit HDD kde mam OS multiboot (tak nechcem tam sachovat s pravami).
Zajtra budem mat disk (ext4) kde su len data, tak ho skusim mountnut (resp. cez bind)

I v tom diskusním fóru píše:
am not sure why you are passing through a block device from the host like this, you can just use
Code:
mp0: /dev/sdc1,mp=/mnt/timeshift,backup=0
instead.
-
Vies mi popisat postup ako si to mountol ?
-
Mount jsem udělal přes fstab na host do /mnt/disk
A pak tuto složku přes ten bind mount do kontejneru.
Není to klasické dání HW přímo do VM, jak chceš ty do LXC, ale funguje to.
Oficiální vyjádření pro tvůj případ je stejně: run the whole thing in a VM, and use regular disk passthrough.

Tak nakoniec sa mi podarilo mountnut fyzicky disk /dev/sdb do LXC aj s automountom pri starte systemu.
Isiel som znova podla toho isteho navodu https://forum.proxmox.com/threads/container-with-physical-disk.42280/
