[SOLVED] Problem with write permission of CT mounted disk

[jibon57]

Hello,

I am a newbie in proxmox. I have 2 hard disks in my server. In the SSD, I have installed the root proxmox & all the CTs. And using the second hard disk as data disk. After creating a CT I tried to add a mount point & put the disk's location to the 2nd hard disk. I didn't check in "Read only" option but after entering to the CT I can see a new mount point "/dev/loop1" but as a regular user I wasn't able to read on that disk. I was trying this way

root@panel:/# mount /dev/loop1 /data
mount: block device /dev/loop1 is write-protected, mounting read-only
mount: cannot mount block device /dev/loop1 read-only

I am using ubuntu 14.04 on the CT. How I can resolve this problem?

Thanks
Jibon

Proxmox automatically mount additional mount points, so there is no need to do that manually.

Thanks for reply. But can you tell, why I can't get write access for apache user?

Because that user should not be able to writ that device.

So, no way to make it writable for any user?

It is a normal, mounted file system. So you can set user permission like you want. But you cannot access the raw device as user apache.

Please can you also post your container configuration /etc/pve/lxc/<CTID>.conf (just to avoid confusion)

Here is output:

Thank you very much dietmar . I have solved my problem. You where right, I can't give direct permission to write apache users on disk. I have created a new directory & it's working just fine
