The latest updates


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.

Added experimental support for IPoIB interfaces.
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.

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

Added a new option disableDhcp in config.yml.
When set to true, the DHCP server in the docker container will be disabled.

Fixed an issue where SMB/NFS services that aren't associated with any server weren't displayed and couldn't be deleted or modified.

Fixed an issue with pagination in the S3 explorer.

Fixed rgw pools not using the correct crush rule when created.

Fixed displaying the ssh key in the server access dialog.

Fixed debian update failing because of testing name change.

Added a check when creating a bond for the length of its name (max. 15 characters).

Fixed an issue when doing a rolling restart of SMB services.

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.

Updated the nfs-ganesha template for better performance.
We suggest using the updated default template for the ganesha config.

Added option to configure index and extra pool for RGW placement rules.

Experimental support for openSUSE.
Added support for our croit images based on openSUSE instead of debian. These images are currently only available as nightly images. Debian and openSUSE images should not be mixed on the same cluster.

The kernel commandline template has been updated.
Any previous changes made to the template are stored as a new preset "custom-old". The new template is required for openSUSE images.

Removed hook script parameter for Pre/PostNetworkConfig hooks.
Due to changes with our network setup procedure, the parameters for changed NICs has been removed.

When selecting a pool, you can now use the "Scrub" button to start a scrub operation on the pool.

Added configurable timezones for snapshot schedules.
The timezone for schedules can be configured in the snapshot schedule tab.

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.

This allows reusing an OSD ID when wiping an OSD.
