We would like to inform you that the ownCloud service will be unavailable on Wednesday June 15, 2016 from 9 AM because of a necessary server security update. Expected duration of the outage is about 2 hours.

Thank you for understanding and we are sorry for the inconvenience.

We would like to inform you that because of the ownCloud server upgrade, ownCloud clients version older than 1.7 are no longer supported with our service.

We would like to recommend you to use the current version (2.1.1) of the ownCloud client (except 1.8.0 and 1.8.1 which have problems described in other news, see below).

The client usually offers update when a new version is released. You can also download current version from https://owncloud.org/install/#install-clients .

If you have any inquiries, kindly contact us by mail to du-support@cesnet.cz

The ownCloud service is operational again. If your desktop and/or mobile client is running, it will connect automatically.

It is also possible to upgrade to current client version, such as 2.1 or 2.1.1. The issue with file permission has been resolved.

The CESNET ownCloud server has been upgraded to version 8.2.2. Interesting “user visible” changes are, e.g.:

• the server is compatible with newest clients 2.1 and 2.1.1.,
• the web interface is more intuitive,
• deleted files are organised in folders,
• ownCloud supports sharing data with users of other ownCloud instances; if you are interested in this feature, kindly contact us so that we can configure and allow sharing with your partners,
• various notifications can be set up in the web interface (e.g. about file sharing) and the notifications can be aggregated,
• many bug fixes and minor improvements; you can find a detailed list of changes at https://owncloud.org/changelog/ (search for differences in versions 7 and 8).

We would like to inform you that server upgrade will be performed. ownCloud service will be unavailable from Wednesday February 17 about 9 AM until at most Sunday February 21. We advise you to synchronise necessary files to your computers in advance.

We will inform you when the upgrade is finished.

If you have any inquiries, kindly contact us by replying to this mail to du-support(at)cesnet.cz.

This announcement was distributed to all ownCloud service users who have home institutions providing correctly mail addresses to the identity federation.

Thank you for understanding and we are sorry for the inconvenience.

https://owncloud.cesnet.cz reached a five thousand active users on 4th of February and the number is increasing.

Outage of Jihlava storage facility (du2.cesnet.cz) has been observed last night. The outage affects both filesystem services as well as the ownCloud service. We are intensively working on the issue and we apologize for the problems.

Update: All services include ownCloud are up and running

We would like to inform you that starting from September 9, 2015, a necessary update of owncloud.cesnet.cz will be performed. ownCloud service will not be available from September 9, 8:30 AM. We expect finishing all updates by the afternoon of September 10.

Web interface as well as file synchronisation will not be available during maintenance. We recommend you to download/synchronise files necessary during the period to your local computers in advance.

We are sorry for the inconvenience. No other CESNET data storage services will be affected.

We would like to inform you that usage of personal computer ownCloud client version 1.8.1 and older is strongly discouraged with our service. The client has an error that is observed from time to time, but it can cause file corruption during file upload to the server. ownCloud clients for mobile platforms are not affected at all.

We would like to recommend you to use current version of the ownCloud client for personal computers (Windows, Linux, Mac), i.e. at least version 1.8.3.

The client usually offers update when a new version is released. You can also download current version from
https://owncloud.org/install/#install-clients .

If you have any inquiries, kindly contact us by mail to du-support@cesnet.cz

Certificate was changed on the servers store[1-6].du1.cesnet.cz on 2 June 2015. New certificate can be identified by the following fingerprints:

   SHA256: CA:B0:8F:CD:98:14:9D:02:15:3B:94:9B:B2:93:6E:D0:38:82:4E:7C:BB:56:B2:ED:DB:01:B0:4E:43:A2:45:00

We would like to inform you that usage of personal computer ownCloud client version 1.8.0 is strongly discouraged with our service. The client has an error that is observed from time to time, but it deletes the local copy of the data on the personal computer. While this error is unpleasant, there is no risk of data loss (as explained below).

How to proceed.

You can find version number of your client in Settings - General. If the version is any other than 1.8.0, everything is OK. Just don't install that version on your system.

The error should be also corrected in version 1.8.1. This upgrade has not been released yet, though.

Instead of 1.8.0, install version 1.7.1 from https://owncloud.org/changelog/desktop/

If you have observed deleting local files by client version 1.8.0, and/or you have observed any other synchronisation problems, you can force resynchronisation of the local copy of the data as follows:

1. stop and uninstall client version 1.8.0
2. in the main ownCloud folder, there is file named .csync_journal.db. Move it outside the ownCloud folder or rename it (if you prefer to keep it for an analysis; otherwise you can just delete it)
3. install client version 1.7.1 from https://owncloud.org/changelog/desktop/ and run it
4. local data will be synchronised with the server; please keep in mind this operation can last several hours depending on the amount of the data
5. just to be sure, kindly check the contents of the “waste basket” in the ownCloud web interface (button “Deleted files”)

Details–why no risk of data loss is connected with this client error:

1. the client deletes just the _local_ copy of the data on your computer, the data on the server is not affected
2. even real deleting files on the ownCloud server is realised by moving them to the waste basket (“Deleted files” button in the web interface)
3. all data in your ownCloud archive are backed up by us once a day

If you have any inquiries, kindly contact us by mail to du-support@cesnet.cz

This announcement was also distributed via mail to all ownCloud service users who have home institutions providing correctly mail addresses to the identity federation.

New Terms of Service will come into effect in February 2015. The only change is that if a user's membership expires (for one reason or another), we will allow the user to download his or her data upon request, when necessary and, of course, if technically possible. It shouldn't be needed very often, but we are happy to assure our users that such a possibility exists.

New website of CESNET data storage services has been put into operation today. Link structure has been modified during the process, resulting in more human readable form. If your bookmarks contain direct links to the web, please update them. We promise that when updating the website again, we'll do our best not to change links again.

By the way, our ownCloud has more than 2000 users now, precisely 2131 today.

https://owncloud.cesnet.cz reached a thousand active users on 30th of June and the number is increasing.

New text of the Terms of Service has been published today. They come into effect in three months, until then the current version is valid. The Terms were mainly updated to reflect real procedures related to Virtual Organisation handling.

Hierarchical storage in Pilsen (*.du1.cesnet.cz) will be inaccessible on May 7, 2014, from 8.30 AM till 7 PM (expected). Major software patches (bug fixes) will be applied by the system vendor.

FileSender service shell be available during the outage, short periods of inaccessibility can happen though. On the opposite, ownCloud service as well as other storage facilities will not be affected.

We apologise for the inconvenience and hope for your understanding

ownCloud is a service to access, sync, and share files. ownCloud is now hosted by CESNET storage servers. It provides web access to your files and synchronizes your data among your computers as well as mobile devices. Access to the service is federated.

Documentation is available in the documentation section. You are advised to check the documentation especially for links to free ownCloud mobile clients as well as setup instructions.

To create an account and to access the service, use https://owncloud.cesnet.cz.

Today was overcome by another “nice” number: storage located in Pilsen administered for 2 PB of data that is stored. This number represents cast of 1001 tapes.

This is a service for copying large amounts of data over long distances using a web interface. You can transfer data between your home directory in the data storage CESNET and the other remote repositories supporting GlobusOnline or your workstation/laptop with installed client.

You can read more in the following guide.

Users from MetaCentrum can get direct access to the data stored in Pilsen. The storage CESNET is connected to all machines of MetaCentrum. Users from MetaCentrum can use storage for storing valuable archival data.

Into resources available in a virtual organization called Storage, we added a data storage area with migration policy tape_tape. Migration policy determines to which the storage layer the data will be stored and under what circumstances it has changed.

Users from VO Storage (including already exist) was a reference to the space added to their home directories. The current policy cache_tape suited mainly for storing small data that is more vivid. Tape_tape space is suitable for storing personal backups and archives that are rarely accessed. Disk space policy tape_tape also allows you to set greater quotas for more comfortable working with large data. If the user finds quota insufficient, we can change it.

For details, see on description of migration politicies.

We changed shell for SSH access to the store in Pilsen to BASH. Its main advantages are

• you don't need to call ssh for each command you want to execute,
• you can use the command output for the input of another command by using pipe

If you are using ssh access to the data storage in scripts, you don't need to change anything. But the new setting is more user friendly.

Detailed description of ssh access you can find in guide.

From now we are fully support HPN-SSH patch that was previously deployed on our servers. Patch brings higher speed transfer using SSH protocol. Improvements can be observed even without the application of patches on your side, but the best results are obtained by using a modified SSH client, which automatically starts using parallel AES encryption.

Since rsync, SCP and SFTP protocols are tunneled through SSH, acceleration is reflected even in these protocols.

Update: Because of instability of HPN patch in some cases, we removed this patch from SSH binaries.

We made extensive reconfiguration of arrays stored in Pilsen. We changed the location of the home directories and directories of each virtual organizations.

We recommend users to familiarize themselves with the new structure, which is described in guide.

2 February 2013 was updated FileSender from version 1.1 to 1.5rc1 (https://filesender.cesnet.cz/). Between main advantages of this version belong full HTML5 support and a new languages support.

With support for HTML5 in the browser FireFox or Chrome we can upload or download files without the need to install Adobe Flash Player. Browser Internet Explorer in the most popular versions has still problem with HTML5, so there is still required a presence Adobe Flash Player to upload the file.

Language in FileSender will automatically switch according to language preferences in the browser - to user witch Czech preferences will automatically appears Czech environment, to user with Norwegian preferences will automatically appears Norwegian.

Update was made without losing data - files previously recorded or created invitations are still valid.
