Outage of Project Storage

Status: Status/green.gif

2019-09-17 12:11: At the moment the power has been reestablished after the outage there was again a failure of the storage system until 12:30.
2019-09-05 15:30: Project homes on bluebay are unavailable until 19:10 due to another hardware failure
2019-08-28 07:00: Whilst the service is running stable we have still open ongoing communication with the cluster filesystem developers to further track down the issues seen in the last weeks.
2019-08-22 06:00: Planned reboot of second system in cluster and related managment node.
2019-08-21 06:00: Planned reboot of first system (expect downtime of 5-10 minutes).
2019-08-18 03:45: Full sync of the missing storage targed finally succeeded. For now full redudancy regained. We are still in contact with the developers of the cluster filesystem to further analyse the problem.
2019-08-14 08:00: Full redundancy is still not regained. We are as well in contact with the developers of the cluster filesystem to analyse the current problems.
2019-08-12 07:00: Sync of the last storage target is ongoing and reached 82%.
2019-08-08 18:00: Heavy load on the storage system while still needing to perform resync caused high latencies on access. Several services were unavailable or responded very laggy until up 22:30. Situation is normalizing but until the full re-sync succeeds there is potential for further outages.
2019-08-08 15:55: The storage system is operational again and an initial high load phase due to resynchronization is finished.
2019-08-08 14:28: There are again problems with the storage servers...
2019-08-07 16:30: Due to errors while re-syncing the remaining target we needed to restart a full sync on this last target. Unfortunately this means that redundancy in the storage system will not yet be regained.
2019-08-07 06:55: High I/O load on the system during further syncing caused accessing issues on the projects between 06:15 and 06:55. There is still an issue with one target which needs a re-sync which might cause further access outages.
2019-08-06 10:50: Re-syncing is still ongoing, one storage target is missing, redundancy of the underlying storage system is not yet regained.
2019-08-05 13:00: Re-syncing of the broken targets is still ongoing, thus redundancy of the storage system is not yet regained.
2019-08-02 17:00: NFS throughput has normalized, causes are investigated. Recurrences have to be expected.
2019-08-02 15:50: High load on the storage server slowed down NFS connections down to timeouts.
2019-08-02 15:05: The synchronization from the healthy system 2 to system 1 has again been started. Once this synchronization is complete (in roughly 3 days), the system is finally redundant again.
2019-08-02 12:45: The hardware has been fixed. The storage services (NFS/Samba) have been powered on.
2019-08-02 11:50: The failing hardware component is currently being replaced by the hardware supplier.
2019-08-02 10:00: The failing hardware of system 1 has been identified. Availability of hardware replacement parts and successful data consistency check will determine the availability of the storage services.
2019-08-02 08:30: The replaced hardware in system 1 is again faulty, while system 2 seems (hardware-wise) ok. Due to data inconsistency, the storage service can not provide its services.
2019-08-01 16:30: While system 1 has not synchronized all data from system 2, the latter system goes down. Starting from here, project and archive storage is not available anymore.
2019-07-31 22:00: A high load of one of the backup processes leads to an NFS service interruption. After postponing that backup process, NFS recovers.
2019-07-31 21:30: The hardware failure lead to two corrupt storage targets on system 1. After reinitializing the affected targets the synchronization of data from the healthy system 2 starts.
2019-07-31 15:45: Service is restored, hardware exchange was successful. Restoring full redundancy is pending.
2019-07-31 15:00: Project homes on bluebay are unavailable due to replacement of faulty hardware part. Estimated downtime of ~1h.
2019-07-31 07:40: Service is restored, still running with reduced redundancy
2019-07-31 06:20: Project homes on bluebay are unavailable due to deactivation of faulty hardware part
2019-07-31 02:40: Storage system 2 took over. Service is restored but running with reduced redundancy.
2019-07-31 02:30: Project homes on bluebay are unavailable due to a hardware failure on system 1

Outage net_scratch service

Status: Status/green.gif

2019-08-28 07:00: The old server is now decomissioned. We will re-bootstrap the service on new hardware in next weeks and re-announce the service when ready to be used.
2019-08-12 07:00: Read-only access to partially recoverable data has been removed again as planned. We are planning to re-instantiate the service on new hardware.
2019-07-26 12:00: Read-only access to partially recoverable data has been made available on login.ee.ethz.ch under /mnt. This volume will be available until August 9th.
2019-07-23 08:00: We are in contact with the hardware vendor to see on further steps to take with the respective RAID controller and double-check if there is an issue with it. Data on the net_scratch is with a high change lost.
2019-07-22 15:35: We still try to recover the data but the filesystem got corruption due to a hardware hickup on the underlying raid system. Affected by this is /itet-stor/<username>/net_scratch.
2019-07-22 12:00: Filesystem errors for the device holding the net_scratch service were reported. The server is currently offline due to severe errors on the filesystem.

Disabling ptrace on managed Debian/GNU Linux computers

Status: Status/green.gif

2019-07-22 09:00

New images are rolled out. As clients reboot they will automatically pick up this new release with a fixed Linux kernel.

2019-07-21 15:00

New images are available. On next reboot of an managed client will boot with a patched kernel and the mitigation disabled.

2019-07-19 13:00

A current Linux kernel bug allows any unprivileged user to gain root access. A proof of concept code snippet that exploits this vulnerability is publicly available.
To protect our systems we temporarily disabled ptrace(2) on all managed Linux systems. All software depending on ptrace(2) will completely or at least partially fail. A prominent example is the GNU Debugger gdb.
A patched Linux kernel will come soon. Once this new kernel is running, we will enable ptrace again.

2019-04-24 14:18: Virtualisation cluster back with full redudancy. User affecting virtual machines were back online already at 07:30.
2019-04-24 13:00: A issue between the redunant switches caused the network issue, leading the cluster to be in an inconsistent state and rebooting all virtual machines. Networking people are investigating further the issue between the switches.
2019-04-24 09:00: Further analysis ongoing, but healt status of virtualisation cluster was affected leading to resets of all hosted virtual machines.
2019-04-24 07:30: We are bringing services back to normal.
2019-04-24 07:00: A planned outage in ETZ building caused stability issues on serveral services of D-ITET in particular HOME and mail services.

Jabba Tape Library HW Problems

Status: Status/green.gif

2018-08-17 07:00: Update: All tape library issues have been solved. All backup and archive services are back online
2018-08-15 12:00: Update: There are still issues with the tape library. It will be down for at least another day.
2018-08-13 11:30: Update: The failed tape drive has been replaced. The management PC is still not working. Due to the very old hardware the supply with spare parts does take longer as usual. The tape library remains offline at least until tomorrow afternoon.
2018-08-10 10:00: Due to a failed tape drive and a defective management PC Jabba's Tape Library is not working. The Jabba server is not affected. We are in contact with IBM and we hope the problem will be fixed by next Monday.

What does this mean for you:

BACKUP
- Store new data: New data are stored to a SAM-FS cache area first, but can not be written to tape afterwards, i.e. the backup process can not be completed finally, but will started automatically as soon as the tape library works again.
- Access existing data: Only access to data still available in the SAM-FS cache area is possible. NO ACCESS to data located on tape only.
ARCHIVE
- Store new data: New data are stored to a SAM-FS cache area first. In second step data are copied to a archive disk but the second copy to a tape will fail. I.e. the archive process can be completed for one half only. The copy-to-tape will started automatically as soon as the tape library works again.
- Access existing data: there is no limitation in access to archive data

  2019-08-12 07:00:: Sync of the last storage target is ongoing and reached 82%.
  2019-08-08 18:00:: Heavy load on the storage system while still needing to perform resync caused high latencies on access. Several services were unavailable or responded very laggy until up 22:30. Situation is normalizing but until the full re-sync succeeds there is potential for further outages.

  2019-08-02 10:00:: The failing hardware of system 1 has been identified. Availability of hardware replacement parts and successful data consistency check will determine the availability of the storage services.
  2019-08-02 08:30:: The replaced hardware in system 1 is again faulty, while system 2 seems (hardware-wise) ok. Due to data inconsistency, the storage service can not provide its services.
  2019-08-01 16:30:: While system 1 has not synchronized all data from system 2, the latter system goes down. Starting from here, project and archive storage is not available anymore.

  2019-08-28 07:00:: The old server is now decomissioned. We will re-bootstrap the service on new hardware in next weeks and re-announce the service when ready to be used.

  2019-08-12 07:00:: Read-only access to partially recoverable data has been removed again as planned. We are planning to re-instantiate the service on new hardware.

  2019-07-26 12:00:: Read-only access to partially recoverable data has been made available on `login.ee.ethz.ch` under `/mnt`. This volume will be available until August 9th.

  2019-07-23 08:00:: We are in contact with the hardware vendor to see on further steps to take with the respective RAID controller and double-check if there is an issue with it. Data on the `net_scratch` is with a high change lost.

  2019-07-22 15:35:: We still try to recover the data but the filesystem got corruption due to a hardware hickup on the underlying raid system. Affected by this is [[Services/NetScratch|/itet-stor/<username>/net_scratch]].

  2019-07-22 12:00:: Filesystem errors for the device holding the `net_scratch` service were reported. The server is currently offline due to severe errors on the filesystem.

  2019-07-21 15:00::

   A current Linux kernel bug allows any unprivileged user to gain root access. A proof of concept code snippet that exploits this vulnerability is publicly available.

   To protect our systems we temporarily disabled {{{ptrace(2)}}} on all managed Linux systems. All software depending on {{{ptrace(2)}}} will completely or at least partially fail. A prominent example is the GNU Debugger {{{gdb}}}.

   A patched Linux kernel will come soon. Once this new kernel is running, we will enable {{{ptrace}}} again.

  2018-08-15 12:00:: '''Update:''' There are still issues with the tape library. It will be down for at least another day.

  2018-08-13 11:30:: '''Update:''' The failed tape drive has been replaced. The management PC is still not working. Due to the very old hardware the supply with spare parts does take longer as usual. The tape library remains offline at least until tomorrow afternoon.

  2018-08-10 10:00:: Due to a failed tape drive and a defective management PC Jabba's Tape Library is not working. The Jabba server is not affected. We are in contact with IBM and we hope the problem will be fixed by next Monday.

What does this mean for you:
  * BACKUP
    * Store new data: New data are stored to a SAM-FS cache area first, but can not be written to tape afterwards, i.e. the backup process can not be completed finally, but will started automatically as soon as the tape library works again.
    * Access existing data: Only access to data still available in the SAM-FS cache area is possible. NO ACCESS to data located on tape only.

  * ARCHIVE
    * Store new data: New data are stored to a SAM-FS cache area first. In second step data are copied to a archive disk but the second copy to a tape will fail. I.e. the archive process can  be completed for one half only. The copy-to-tape will started automatically as soon as the tape library works again.
    * Access existing data: there is no limitation in access to archive data
