I am getting the following error while I am trying to edit default lxc profile:
The "default" storage pool doesn't exist
/snap/bin/lxd init
or
lxd init
solved the issue, but select yes for following:
Do you want to configure a new storage pool? (yes/no) [default=yes]:
Then you can confirm with the following command and the output:
/snap/bin/lxc storage list
+---------+-------------+--------+--------------------------------------------+---------+
| NAME | DESCRIPTION | DRIVER | SOURCE | USED BY |
+---------+-------------+--------+--------------------------------------------+---------+
| default | | zfs | /var/snap/lxd/common/lxd/disks/default.img | 1 |

i have installed cinder in controller node and block node.
i test the status of openstack-cinder-scheduler and openstack-cinder-api(on controller node) ,openstack-cinder-volume and target.service(on block node),that they are running.
but when i use the "cinder list,cinder create,openstack volume service list"only can get one kind of output:
[root#controller //]# openstack volume service list
The server is currently unavailable. Please try again at a later time.
The Keystone service is temporarily unavailable.
(HTTP 503)
[root#controller //]# cinder list
ERROR: The server is currently unavailable. Please try again at a later time.
The Keystone service is temporarily unavailable.
i have check the configure in cinder.conf,nova.conf serveral times.i have no idea with them.can u give a suggestion? thank you.
I found that I can create volume by dashboard, while by command line I can't. It may be something wrong between admin and cinder user. Try it again.
[root#controller //]# openstack volume list

20 days ago I've successfully provisioned for ESP-32 and work fine with this device.

However, I cannot start the application on this device:
michael_k # michaelk: ~ /toit_apps/Hsm2/tests $ toit run test_hsm_switch_async_4.toit
No default device set. Provide the device name (with the --device flag) to the command
michael_k # michaelk: ~ /toit_apps/Hsm2/tests $
I realized that this new device needs to be given a different name from my default device micrcx-1. By the way, I can see my first appliance:
michael_k # michaelk: ~ /toit_apps/Hsm2/tests $ toit devices
+--------------------------------------+----------+-------------------+----------+
| DEVICE ID | NAME | LAST SEEN | FIRMWARE |

+--------------------------------------+----------+-------------------+----------+
michael_k#michaelk:~/toit_apps/Hsm2/tests$
So, the question is: how to give a name to a new additional device and how to run an application on it?
Thanks in advance, MK
PS. Naturally, I could be wrong, but as far as I remember, the name of the first device was assigned by toit system automatically. I had nothing to do with this. micrcx is my computer's identifier.
It might be that your device wasn't claimed yet.
In the current release (but hopefully not in future releases), provisioning a device only puts the Toit framework on the device. At this point it is not yet associated with your account and must be claimed.
You can simply run:
toit device claim <hardware-ID> or toit device claim <hardware-ID> --name=<some-name>.
If no name is provided, then the system generates one. Typically these are built out of two words, for example nervous-plastic. You can always change the names at a later point.
Alternatively you can claim the device in the web UI. There is a "CLAIM OR REPLACE DEVICE" button on the top right of the "Devices" view.
FYI: I have edited your post to remove the hardware ID of the new device, so nobody else claims the device in the meantime.
In our company we're using ansible to target different environments, about 10 on the development and integration side, and 3 on the production side. Those environments have some differences in terms of the number of resources dedicated. For example let say in production we have a standalone server or vm dedicated to run the jvm, another one for dB... And in certain other environments those applications share the same server or vm. The problem is that some playbooks needs to be tweaked in order to target such an environment, so how could we do to make it as generic and transparent as possible?
Thanks for your advices
what you want to achieve is putting good hosts in good groups.
if you're familiar with ansible-inventory --graph, here is what you want to achieve:
#all:
|--#dev:
| |--devel1.domain.org
| |--devel2.domain.org
|--#db:
| |--db1.domain.org
| |--db2.domain.org
| |--dbprod1.domain.org
| |--appprod2.domain.org
|--#app:
| |--app1.domain.org
| |--app2.domain.org
| |--appprod1.domain.org
| |--appprod2.domain.org
|--#dev1:
| |--devel1.domain.org
| |--db1.domain.org
| |--app1.domain.org
|--#dev2:
| |--devel2.domain.org
| |--db2.domain.org
| |--app2.domain.org
|--#prod:
| |--#prod1:
| | |--dbprod1.domain.org
| | |--appprod1.domain.org
| |--#prod2:
| | |--appprod2.domain.org
here the host appprod2.domain.org will inherit from group_vars of app,db, prod,prod2
I have a problem with file storage organization.
There is a network of Windows 7 and Windows XP computers. One of them is a file storage server.
Software packs are located on the storage server. Each software pack includes
1. active folder;
1. some folders for each program.
(see the structure example below)
Active folder is a structure of the actual program's versions, must allow to copy all the software in their actual versions avoiding file's duplicating via direct copying. Also fast switching of actual version is needed.
Program folders contain folders for each program's version.
I tried to solve the task via windows directory junction. I created the links via Far Manager 3, command Alt+F6, type directory junction.
Desired structure example
+---active % 389 MB, desired package of actual software
| +---notepad++ % directory junction
| | \---7.3.1
| | npp.7.3.1.Installer.exe
| | npp.7.3.1.Installer.x64.exe
| |
| +---octave % directory junction
| | \---4.2.1
| | octave-4.2.1-w32-installer.exe
| | octave-4.2.1-w64-installer.exe
| |
| \---texstudio % directory junction
| \---2.12.4
| texstudio-2.12.4-win-qt5.6.2.exe
|
+---notepad++
| +---6.8.8
| | npp.6.8.8.Installer.exe
| |
| \---7.3.1 % actual version
| npp.7.3.1.Installer.exe
| npp.7.3.1.Installer.x64.exe
|
+---octave
| +---4.2.0
| | octave-4.2.0-w32-installer.exe
| | octave-4.2.0-w64-installer.exe
| | octave-4.2.0-w64.zip
| |
| \---4.2.1 % actual version
| octave-4.2.1-w32-installer.exe
| octave-4.2.1-w64-installer.exe
|
\---texstudio
+---2.11.0
| texstudio-2.11.0-win-qt5.5.1.exe
|
+---2.12.0
| texstudio-2.12.0-win-qt5.6.2.exe
|
+---2.12.2
| texstudio-2.12.2-win-qt5.6.2.exe
|
\---2.12.4 % actual version
texstudio-2.12.4-win-qt5.6.2.exe
Local usage
Local means I operate on the storage server's Windows GUI.
If to copy active folder to another server's folder observed result is the same as desired:
TEST_COPY
\---active % 389 MB, all the files are copied
+---notepad++
| \---7.3.1
| npp.7.3.1.Installer.exe
| npp.7.3.1.Installer.x64.exe
|
+---octave
| \---4.2.1
| octave-4.2.1-w32-installer.exe
| octave-4.2.1-w64-installer.exe
|
\---texstudio
\---2.12.4
texstudio-2.12.4-win-qt5.6.2.exe
Network file access
If to access to the storage server's active folder via network sharing and copy it the desired result does not happen.
Of course, tree /A /F command shows the same structure of the copied tree, but active is 0 MB size and child folders notepad++, octave, texstudio are also zero-sized and empty.
TEST_COPY
\---active % 0 MB, no any files, only subfolders
+---notepad++
| \---7.3.1
|
+---octave
| \---4.2.1
|
\---texstudio
\---2.12.4
Only if try to copy directly directory junctions subfolders inside active folder (7.3.1, 4.2.1, 2.12.4) the content will be copied as desired. But every user wants to copy active folder, not its second level childs.
BTW. Sometimes when trying to copy an error occurred: file/folder already exists, and copy process was broken unexpectedly.
May be links are set up wrong or there are other methods to reach the desired result.
I have created a new MapRDB table with the below privilege.
"adminaccessperm":"u:root | u:mapr | u:test",
"deletefamilyperm":"u:root | u:mapr | u:test",
"defaultappendperm":"u:root | u:mapr | u:test",
"defaultreadperm":"u:root | u:mapr | u:test",
"defaultwriteperm":"u:root | u:mapr | u:test",
I am trying to delete the table as a test user. I am not able to delete the table.
I am getting the below error.
ERROR: User test(user id 503) does not have access to /EDMEVENT/events_1
You have to have full control permissions in order to delete. You can modify cluster permissions using the acl set and acl edit commands, or using the MapR Control System. Detailed steps can be found Cluster and Volume Permissions
