Or need more storage to store the needed files. Solutions Remove old Cryptshare Backups (Versions older than x) Click to see detailled instructions... By default the Cryptshare Server performs a Backup on a daily basis.these backups are not automatically deleted and therefore can occupy disk space. Please update to the actual Cryptshare Version In order to free disk space you can manually remove old backups from the file system. The default location for Cryptshare Backups lies within the Cryptshare Installation folder in the subdirectory 'backup'. Depending on your Operating System you can enable a backup rotation as described here: Act ivate Backup-Rotation on Cryptshare Appliances under opensuse Remove old kernels Click to see detailled instructions... Applies to All versions of opensuse Purpose During the lifecycle of an appliance, it may have gone through several updates, including kernel updates. The old kernels are not deleted by default and have to be removed manually. Each installed kernel takes up about MB of disk space. This article explains how to remove these unused kernels from the appliance. Solution Creating a backup If you're unfamiliar with managing Linux systems, it is strongly recommended to create a snapshot of the appliance. Removing the wrong kernel (e.g. the one currently in use) may result in a non-booting appliance. To remove old kernels, please proceed as follows: Reboot the system to ensure that your system is booting the most recently installed kernel. Display the kernel version in use and write it down for the duration of this tutorial. The output may look as follows:

2 cryptshare:~ # uname -r default 3. Display all installed kernels. cryptshare:~ # rpm -qa grep -i kernel kernel-default x86_64 kernel-firmware noarch kernel-default x86_ Only consider the entries containing "kernel-default" or "kernel-desktop". As you can see in this example, a kernel version older than the one currently in use is installed: kernel-default x86_64 Start with the oldest installed kernel and remove it from the system as follows. cryptshare:~ # zypper rm kerneldefault Loading repository data... Reading installed packages... Resolving package dependencies... The following package is going to be REMOVED: kernel-default package to remove. After the operation, MiB will be freed. Continue? [y/n/...? shows all options] (y): Carefully read through the package removal summary and, once confident with the correctness, confirm by pressing Enter. (Hint: additional packages such as vmware-guest-tools may also be listed for removal - this is fine.) Repeat the above step for all kernels that do not match the kernel currently in use After zypper has finished the removal process, you've successfully freed disk space.

3 Limit the size of journal logs Click to see detailled instructions... Applies to All versions of opensuse Purpose This article describes how to limit the size of the journal logs. Since the journal logs are likely to grow up to hundreds of MB, they might occupy a significant amount of disk space on your Cryptshare Server. Solution To limit the size of the journal logs to 10MB, please follow the instructions below: Connect to your Cryptshare Server via SSH Verify current disk space usage: df -h 3. Limit the size of the journal: sed -i -e 's/#systemmaxuse= /SystemMaxUse=10M/' /etc/systemd /journald.conf 4. Reboot your Cryptshare Server: reboot 5. Verify that the disk space usage went down: df -h Related articles
