OpenMediaVault installation in LXC with attached HW block device

Inside container there's /dev/sdc and /dev/sdb.
Maybe there's problem that my drives are formated as whole /dev/sdb (and /dev/sdc) but not contains any partition.
I would like not to reformat them due to that they contain big amount of data.
 
Hi.
To correctly mount inside container any block device you need at least two devices:
- "physical" device (/dev/sda for example)
- "partitioned and fs-formatted" device of the mentioned above "physical" device (/dev/sda1 for example).
Do you have /dev/sdc and /dev/sdc1 in container?
 
I has the same problem.

Hello,

Thank you for your tutorial. I managed to get my 2 disks to appear in OMV and I can mount them individually.
However, I have two problems:
1- when I restart OMV, they don't automount
2- when I try to create a Union Filesystem in OMV, I have this error:
Code: 
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; mount -v '/srv/834990ca-b113-42b7-9f48-3bda5714862d' 2>&1' with exit code '1': fuse: device not found, try 'modprobe fuse' first

Here are my config files.

/etc/pve/lxc/100.conf:
Code: 
arch: amd64
cores: 4
hostname: omv.2566335.lan
memory: 2048

mknod -m 777 ${LXC_ROOTFS_MOUNT}/dev/sdc b 8 32
mknod -m 777 ${LXC_ROOTFS_MOUNT}/dev/sdc1 b 8 33

Could you tell me what I did wrong or missed? Thank you.

I tried adding
Code: 
lxc.mount.entry: /diskmedia1 srv/dev-sdb1 none bind,create=dir,optional 0 0
lxc.mount.entry: /diskmedia2 srv/dev-sdc1 none bind,create=dir,optional 0 0
to /etc/pve/lxc/100.conf but it didn't change anything. I don't understand this part so I probably got it wrong.

I did it but have more problems:
I can mount and umount both dane1 and dane2 filesystems, without errors (inc. apply of course)
but when I try to format umounted dane2 this is what I get:
Code: 
Device '/dev/dm-0' does not exist.
this is less important, but when I would like to make a share from dane2 and click apply this is what I get:
Code: 
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; systemctl start 'sharedfolders-dane2.mount' 2>&1' with exit code '4': Failed to start sharedfolders-dane2.mount: Access denied See system logs and 'systemctl status sharedfolders-dane2.mount' for details.

...first I reopen this old thread ..., informations here are very valuable for me, but I need a little help....

My context:
I have an old PC (limited ressources: core2duo intel 2.93GHz, 4Go Ram- SSD for Proxmox, and 2 mecanical Sata HD for more storage).
I install OpenMedialVault 6.2 as an LXC container (to minimize overhead of a full VM), and I'm able to mount the 2 mecanical sata drive on the OMV container.

My Problem:
The successful mount in OMV is very very slow,
I see syslog message every 30 secondes, that mount failed ... and then 2 mn after, HD are mount correctly !
After that everything work correctly : in OMV GUI I am able to define the Storage/Disk/File Systems/Share...
This is NOT a blocker ... but this 2 minutes startup is really annoying ... and I don't understand where it come from ....

If you have any idea, how can I investigate that ? I would appreciate your help

In the container OMV add the standard line
/etc/fstab
