Marked the upgrade to Ceph Reef as stable.
Updated the CRUSH map view.
The CRUSH map is now more compact to allow displaying more OSDs at once. It also has a search field in the top right, allowing you to quickly search for an OSD or server.
Added support for running multiple RGW or MDS on a single server.
This feature needs to be enabled in the croit settings (see here).
We don't recommend running multiple RGW/MDS per server in general, but in certain hardware setups it may lead to better performance.

Added support for active/passive bonds over Infiniband in the new croit UI.
This was previously blocked in the UI and is now allowed.
Updated behavior of OnHealthDegrade, OnHealthRecover and OnHealthImprove hook events to ignore muted warnings.
Updated and fixed the SNMP hook script.

You can now select and IPMI interface and click on "Go To IPMI" to open the IPMI interface in a new tab. You can also double-click on the interface.
Added some settings to configure croit's CORS behavior.
Fixed the "Turn on LED" button on the CRUSH map view.
This button didn't work as expected and turned on the LED of an incorrect disk. Note that this only applied to the CRUSH map page.
Fixed MDS service state showing "UNKNOWN" sometimes in the new croit UI.
Fixed several issues in the croit UI when editing ceph keys.

mkfs.xfs may take longer than expected on large disks, so the timeout for that was increased.
Small improvements to auto-updater.

v2205.0

The croit Pacific (and later) container is now used as the default croit/croit:latest container. Users running an older (pre-pacific) ceph version should update to the croit/croit:latest.octopus container instead. The croit app will give you the option to switch to the correct container in case the Pacific container was started on a pre-pacific ceph cluster.
Added option to upgrade to Ceph Quincy.
Warning: We still don't recommend migrating to Quincy (nor Pacific), due to stability issues!

Added Discord notification script to hook script library.
Added support for specific DB/WAL setups using LVM instead of partitions.
Added a small improvement to the Ceph Pacific upgrade procedure.
Fixed a memory corruption issue in the croitd daemon.
Fixed the utilization on the status page to display the maximum utilization per OSD for each device class, instead of an average over OSDs.
Fixed an issue where joining a samba domain failed when the password contains special bash characters.
Fixed an issue where NVMes with multiple namespaces weren't detected as separate disks.
Fixed a compatibility issue with old debian stretch images.
Fixed an issue when doing a minor upgrade to Ceph 16.2.7.

Fixed s3:* not being allowed when configuring bucket policies.
Removed ceph configuration defaults setting active hours for osd scrubs (osd scrub begin/end hour).

v2202.0

Fixed not being able to add more iSCSI gateways on clusters where the iSCSI services take too long to start.
Adding more gateways may have failed on such clusters if the other gateways weren't healthy fast enough.
Fixed an issue that caused a pool .rgw.root to be created despite not using RGW.
Fixed a missing animation when creating OSDs.
Improved performance of the pools page.
Added some small improvements to the Ceph Pacific upgrade procedure.

v2201.1

Added an authenticated endpoint to access file on the management node.
Similar to the existing endpoint serving files in /config/extra-files (inside the croit docker container), the new endpoint serves files from the /config/extra-files-secure folder. The API endpoint is reachable under /extra-files-secure/path-to-file similar to the /extra-files/... endpoint, but needs to be authenticated against using a croit user account with the Secure folder account role (via HTTP Basic authentication).
Fixed an issue that caused some MDS daemons to crash.
The last croit update enabled the messenger v2 protocol for MDS. This can result in the MDS daemons crashing. Messenger v2 is disabled for now if all MDS daemons are not already using v2.
Fixed S3 user stats missing for users that contain '@' in their user ID.
Fixed S3 stats missing for custom zones and placement rules.
The croit-rgw-monitoring ceph key will now be updated to include any necessary RGW pools according to zones and placement rules. If you want to prevent croit from updating this key, and instead manage it manually, add disableRgwMonitoringKeyUpdate: true to your /config/config.yaml inside the croit docker container.
Fixed not being able to edit a user's roles without also changing his password.
Added an option to configure the default command timeout.
To do so, add defaultCommandTimeout: 8 (here for example 8 seconds, the current default) to your /config/config.yaml inside the croit docker container. Generally speaking, this shouldn't be necessary and if you see many timeout warnings in the frontend, please contact croit support (support@croit.io) first.
Added some improvements to the Pacific upgrade to make it more stable.

v2201.0

Added option to upgrade to Ceph Pacific.
Warning: We still don't recommend migrating to Pacific, due to stability issues! Due to compatibility issues between Pacific and older ceph versions (in particular with RGW), we now offer a separate croit container for Pacific clusters. The new container is currently tagged as latest.pacific, and will in the future replace the latest container.
The Pacific upgrade procedure will try to switch to the new container for you. Should that fail, you can also simply update the croit container to latest.pacific manually.
If you intend to stay on an older ceph release, please use the latest.octopus tag from now on, until you decide to upgrade to Pacific. Don't worry if you start the Pacific container by accident, certain features will be blocked, and you will be given the option to switch to the Octopus container again.
Starting with Pacific, our default OS is now openSUSE instead of Debian. After the upgrade, the latest openSUSE image will be selected as new default for your servers. Please update your hook scripts and fix OS-specific commands (e.g. apt-get).
If you have any issues or questions, or need help with any of the upgrade steps, please contact croit support (support@croit.io) for further assistance.
Fixed an issue that caused scheduled jobs (such as automatic updates and backups or scheduled snapshots) to not run anymore.
For users affected by this issue, it also caused log files not being cleaned properly in the croit container, filling up the disk on the management node.
As a temporary workaround for this issue in older croit versions, you can simply restart the croit docker container.

Added toggle for base2 filesizes to RBD view.
Added option for viewer users to change their own password.
Added an extra warning when changing RBD image name or features and improved some error messages when deleting RBD images.
Fixed RGW user stats not being collected and missing from the UI.
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.
Fixed rolling reboot for servers when switching between Debian and openSUSE.
Fixed an issue where servers would show as offline in the croit UI when they had broken NFS connections.
Fixed an issue where a warning about failed backups incorrectly showed up.

v2111.3

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

Fixed default gateways of VLANs not being set up correctly.

v2111.2

Fixed an issue in the croitd daemon when detecting the model name of NVMe disks.

v2111.1

Fixed an issue when detecting different disks with the same WWN in the croitd daemon.
Some disks may have the same WWN with different vendor extensions. The daemon handled this incorrectly before.

v2111.0

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.
Fixed upgrade procedure for MDS services when migrating to a new ceph version.
Fixed not being able to select an EC pool as data pool when configuring a S3 placement rule.

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

v2108.0

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).

v2106.1

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.

Added warning when choosing a default network for automatic ping metrics that doesn't contain all servers.

v2102.2

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.
