There will be some minor Storage Area Network (SAN) maintenance tonight at 5pm. Services are not expected to go down, but there could be occasional minor delays or very short outages.

Home Directory Downtime
home.eecs will go down briefly (a minute or two) twice on Saturday (03/07). The first downtime will be around noon, and the second will probably happen within the hour. This is to replace some failing hardware.
Clients that access home.eecs via Network File System (NFS) should not be affected by this scheduled maintenance. Clients that use Common Internet File System (CIFS), such as Windows and MacOS machines, may notice a disconnection (and should re-connect automatically).

Windows file service outage on home/project today
There will be a brief (few seconds) CIFS outage at 6pm today. This will affect Windows clients and Samba users.
Most people won’t notice the brief outage, but there’s a possibility that some Windows applications with open files may get a bit confused. We recommend all affected users save any open files before 6pm and wait until a few minutes after 6pm to resume work.
The purpose of this brief outage is to resolve a problem that has prevented some Mac users from accessing our file servers. Once we have confirmed that problem has been resolved, a separate announcement will be made.

File Server Slowness
Access to EECS home directories on home.eecs was particularly slow for a while this morning. For users with mail or browser profiles in their home directories, this may have prevented their mail client or browser programs from functioning normally.
Access to project.eecs does not appear to have been affected.
Staff are investigating the cause. The likely culprit are slowdowns from a new backup combined with replication.
The symptoms disappeared at 9:30am on Tuesday, Sep 09. More should be known about the root cause by 9am Wednesday.

Coeus/Project Downtime
Attention System Administrators,
On Wednesday, August 20th from 6am-8am, IDSG will be migrating production file service of home directories and project space to the new NetApp filers. There will be downtime during this migration that will impact the majority of users in the department. Please evaluate the impact for your users and notify them of those details. A much shorter public announcement will be going out soon to the entire EECS community indicating that local System Administrators will be letting them know of any specific information as to how it will impact their work.
The following services will be affected:
– coeus
– project
– sww (not winsww)
– argus
– www.eecs and www.cs web servers
– the IRIS website
The following changes apply:
1. COEUS
– coeus.EECS.Berkeley.EDU will be replaced by home.EECS.Berkeley.EDU.
– NFS access will change from coeus:/vol/vol0/eecs/username to home:/eecs/username
– The amd and automaps will be appropriately changed.
– CIFS access will change from \\\\\\COEUS\HOME\username to
\\\\\\HOME\username
– The old hostname coeus will be a CNAME to home.EECS.Berkeley.EDU until September 20th.
2. PROJECT
– NFS access will change from project:/vol/vol[02]/projspace to project:/proj/projspace
**NOTE**: A few mount points will change in a different way. See the end of this announcement for details.
**NOTE2**: If your project spaces are merged, the details will be worked out with you directly outside of this announcement.
– The amd and automaps will be appropriately changed.
– CIFS share names will not be affected.
This announcement may be followed by additional updates if additional technical details need to be publicized. Certain requests may be delayed beyond the normal response time (e.g. amd/automap change requests, new user creation, project space creation, etc.) during the 2 weeks prior to the migration.
The downtimes for different services will be different. There will be one or more additional announcements as services get restored to allow early access to the appropriate systems. E.g. the actual downtime for coeus/home is expected to be only a few minutes.
This list will receive notice when access is restored.
Sysadmins should be ready to reboot systems that need to remount filesystems between 7:30 and 8 AM. CIFS access should resume during that time as well. The CIFS share names will not change and therefore should not require a reboot for those systems.
Be advised that there are a number of follow-up tasks after the outage, which could result in slow response from these systems.
If you experience problems during or after the outage, or have
additional questions – please contact Helpdesk at help@eecs or 2-7777 or 395 Cory.

Loss of Connections to Coeus and Project
Unfortunately, the changes we made during the scheduled maintenance window to provide better redundancy caused an unforeseen loss of connectivity to our NIS servers on one network. This resulted in loss of mounts to Coeus and Project. We rolled back the changes and service has been restored. We will try again at a later date after we resolve the issue. Unfortunately, the issue was not discovered until after our scheduled downtime was over. We regret the inconvenience this caused.
