I created it with
vzctl set 101 --devnodes sdb1:rw --save
The node is now present in the CT. However, if I try to mount it in
the CT (mount /dev/sdb1 /mnt), no error is reported but mount seems to
have no effect. No files are seen in /mnt that are present on that
partition.
So, I guess, additional steps are needed?
You might need sysfs layout.
Please, strace your mount call and send it as a reply (attached).
Here it is.
As far as I can see in strace log, mount tries to open
/sys/dev/block/8:17, indeed. This file is present on the host but not in
the CT.
Expectable.
Then you have to expose sysfs for this device to the container.
Igor, could you advice, please?
Lets try to use secondary disk feature first
vzctl set VEID --device-add hdd --device /dev/sda --save
No luck. The CT fails to start with "Failed to configure disk" after that.
