I'm just getting started with LXC. I'm trying to add a storage pool,
but it's telling me that it's read-only.
root@debian:/# mkdir /test
root@debian:/# mkdir /test/stor1
root@debian:/# lxc storage create vm dir source=/test/stor1
error: mkdir /test: read-only file system
root@debian:/# ls -laR /test
/test:
total 12
drwxr-xr-x 3 root root 4096 Jul 27 15:42 .
drwxr-xr-x 24 root root 4096 Jul 27 15:42 ..
drwxr-xr-x 2 root root 4096 Jul 27 15:42 stor1
/test/stor1:
total 8
drwxr-xr-x 2 root root 4096 Jul 27 15:42 .
drwxr-xr-x 3 root root 4096 Jul 27 15:42 ..
root@debian:/# rmdir /test/stor1/
root@debian:/# lxc storage create vm dir source=/test/stor1
error: mkdir /test: read-only file system
root@debian:/#
It doesn't seem to matter whether the directory exists or not.
Everything LXC/LXD seems to be running as root, and root owns all the
directory structure where I'm trying to install things, so I don't think
it's a POSIX ACL issue. I even made the parent directory with rwxrwxrwx
permissions.
I was able to add a storage pool beside the default one
+---------+-------------+--------+------------------------------------------------+---------+
| NAME | DESCRIPTION | DRIVER | SOURCE | USED BY |
+---------+-------------+--------+------------------------------------------------+---------+
| default | | dir |
/var/snap/lxd/common/lxd/storage-pools/default | 2 |
+---------+-------------+--------+------------------------------------------------+---------+
| vm | | dir |
/var/snap/lxd/common/lxd/storage-pools/vm | 0 |
+---------+-------------+--------+------------------------------------------------+---------+
But that doesn't help me.
I'm using a pristine Debian 9 install, and have tried both the stable
(2.15) and candidate (2.16) LXC versions, installed as snaps. I have
tried the same command in the try-it online feature, and it works there.
What am I doing wrong?
Tony
