The latest updates


Fixed an issue where servers incorrectly report being out-of-sync with the management node clock and having large clock drifts.

Fixed setting the server-specific variables (e.g. hostname) of the Samba AD domain join templates.
The variables now have the correct values for the server joining the domain.

Fixed default ceph.conf options to have messenger v2 (msgr2) enabled.


Added a template for the Samba AD domain join.
This template can be edited to customize the commands used to join the domain.

Fixed an issue in the croitd daemon when reporting server state on nodes that have no disks.

Fixed an issue when adding or changing NFS exports.
Our daemon will now tell NFS Ganesha to reload the new configuration.

Fixed an issue when monitoring RBD images not in the default rbd pool.

Some disks may have the same WWN with different vendor extensions. The daemon handled this incorrectly before.


Switched to a new network configuration script to set up the network on the cluster nodes.
This setup script is available as the template network-setup and can be edited for custom networks configurations. Should you experience any network issues after upgrading to the new version, please contact croit support. You can disable the new script by adding useNetworkSetupScript: false to the configuration file /config/config.yml inside the docker container.

Improved performance of disk detection by parallelizing it.

Replaced the daemon running on croit nodes with a newer version.
Our croit daemon running on the nodes was rewritten for the future croit platform. If you notice any problems, please let us know.

MAC addresses of such interfaces are 20 bytes long. We use the last 8 bytes for identification, as the first 12 bytes can change over time.

Added the option to edit S3 keys of a user.
Small changes were made to the S3 subuser API (they are put under a /subusers resource to prevent naming conflicts).

Fixed a timeout issue when deleting or flattening large RBD images.

Removed LXC container support.


Fixed an issue when wiping encrypted OSDs that also use a DB/WAL device.
We urge anyone with OSDs with separate DB/WAL devices that used to be encrypted (or still are) to update to the latest croit version without rebooting any servers. The new update will display a warning if your OSDs are affected by this issue. If so, please contact croit support and do not reboot any server.

Added a new page for managing S3 placement rules.
The new page can be accessed under the S3 Explorer tab. Here you can configure new placement rules and add storage classes to these rules. The default placement for individual users can also be configured on the users page. Please note that creating buckets in the croit UI will either use the specified placement rule, or the default rule of the owner.
The API for s3 placements has also changed. If you used this API before, please update your requests or contact croit support for help.

Added task advisor warning for pre-Octopus EOL.

Added a template for DNS configuration (/etc/resolv.conf).
This fixes an issue where the DNS configuration wasn't properly applied to the croit nodes.

Added a template for the keepalived configuration (used for HA groups).


Removed milliseconds from scheduled CephFs and RBD snapshots.
Scheduled snapshots were postfixed with the current time in the format "yyyy-MM-dd.HH:mm:ss.SSS". We removed the milliseconds (SSS) from this format for better compatibility with shadow copies in Samba.

Added descriptions to template variables.

Added a task advisor warning when multiple default gateways are configured.


Users with the Viewer role are now allowed to view the CephFS explorer.
Viewers are only allowed to browse and download files, they can't upload or change any settings.

Support configuring per-pool BlueStore compression.
BlueStore compression can be configured by selecting a pool and clicking on Compression.


Support separate DB and WAL devices.
When creating OSDs, DB and WAL devices can now be specified separately. Previously, croit only supported specifying a single device for both; it would use partition size to determine whether to store only the WAL or both DB and WAL on the device.

Remove kernel commandline dracut template.
croit doesn't provide CentOS images anymore; this removes support for booting CentOS entirely.

Fall back to iproute2 if no MAC is found.
This change allows InfiniBand NICs in IPoIB mode to work with croit.
