EECS Website, FTP, Jabber, and Sympa Offline for Urgent SAN Maintenance

September 23, 2008 by IRIS Staff

Due to some urgent maintenance to the SAN, the EECS Website, EECS FTP server, Jabber, and Sympa (mailing lists) services will be offline from 5:00 p.m. to 6:00 p.m. on Tuesday, September 23, 2008.

The servers hosting the aforementioned services lack redundant connections to the SAN which prevents them from remaining in service during the maintenance. We realize this is an unfortunate limitation and are procuring new hardware which will add the redundancy necessary to handle similar situations more gracefully in the future.

Our apologies for the short-notice and inconvenience.

Windows file service outage on home/project today

September 15, 2008 by IRIS Staff

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.

Resolved as of 2008-09-15 18:13:00

IMAP Server Unresponsive

September 11, 2008 by IRIS Staff

The IMAP service is OK now (7pm).

Resolved as of 2008-09-11 19:00:00

AirBears In EECS

August 25, 2008 by IRIS Staff

AirBears wireless to some locations in EECS (particularly BWRC) was disrupted whereby AirBears clients could not get a lease. Other EECS WLANs were not affected. One wireless controller was shut down and all APs are back up on the other controllers. This may have resulted in a brief outage for some wireless clients.

We will do some more testing on the suspect controller tomorrow morning.

Coeus/Project Downtime

August 20, 2008 by IRIS Staff

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.

New Unix General Login Server

August 7, 2008 by IRIS Staff

We’re pleased to announce login.EECS.Berkeley.EDU, the new Unix general login server running Solaris 10 x86_64.

This server is using [OpenSSH](http://openssh.org) as the SSH daemon, so if you haven’t already [converted your ssh.com ssh keys to OpenSSH keys](https://iris.eecs.berkeley.edu/15-faq/15-software/putty.html#import_key) you’ll need to do so before they’ll work on the new server.

Since login.eecs uses the x86_64 architecture, any binaries that you run from your home directory that were compiled on Sparc will need to be recompiled to work.

This server mounts the Solaris 10 for x86 sww. You should add
/usr/sfw/bin to your path (if you haven’t already) as most open-source software is available on Solaris 10 and therefore will not be on the Solaris 10 sww.

login.eecs will not mount /var/mail from mailspool.CS.Berkeley.EDU as this service will be discontinued in the near future. There will be an
announcement about that soon.

The old Unix General Login Server, argus.EECS.Berkeley.EDU will be phased
out at a later date. There will be an announcement about that soon as well.
