similar to: Measuring migration downtime

What methods do people use to notify users of upcoming downtime in an application, and for handling requests nicely while scheduled downtime is occurring? My Google-fu is not yielding me anything useful-looking. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

After a kernel update (but before rebooting) Is there a way to recompile Zap/Dahdi against the new kernel? My objective is to eliminate the additional downtime that occurs while recompiling/installing zap/dahdi after booting into the new kernel. Please correct me if I'm wrong: My understanding is that until you reboot (after a kernel update), recompiling zap/dahdi still compiles against

Hi While performing migration of a guest virtual machine from a physical node to another, it would be nice if we can figure out the free pages in the guest VM and opt not to transfer them. 1.I came across in the paper "Xen and the Art of Virtualization", that guest VM can be made to give the free pages back to Xen before doing migration. 2.What is the way to figure out free pages in

LLVMers, llvm.org will be down on 2/1 (approximate hours 10pm PST - ?), and 2/4 (8am PST - ?). Email will be sent to the list before and after the downtime. During this time ALL services (svn, web, etc) except for the mailing lists will be down. We are performing a server upgrade that will take some time, so I ask that you have patience. We will try to be as speedy as possible. Please let me

Hello, I have an imap server with huge Maildirs and several users running dovecot 1.0.13, I need to migrate all the imap accounts to a new box which runs dovecot 1.1.4. The requisite is that need to do it with no downtime or minimal downtime possible, and totally transparent for end users. I have tried IMAP<-->IMAP syncing using a master user in both servers and imapsync, however due

Hi, I have a setup with several dovecot-servers (2.2.35) and I use dovecot proxy. I upgraded one server to 2.3.1 and got the configs fixed so far that it started again. But when I tried to add it into the proxying again with "doveadm director add" I see the following in the logfiles: May 6 07:19:30 host dovecot: director: Warning: Director xxx.xxx.xxx.176:9090/out disconnected us with

Just a reminder, LLVM.org will be going down in 1 hour.

llvm.org is now down. I will notify you when it is back up. This will take several hours. -Tanya On Feb 1, 2013, at 9:05 PM, Tanya Lattner <lattner at apple.com> wrote: > Just a reminder, LLVM.org will be going down in 1 hour. > > Thank you, > Tanya > > On Jan 28, 2013, at 2:28 PM, Tanya Lattner <lattner at apple.com> wrote: > >> To be clear: >>

Hello, there will be a downtime of the mail and list server tomorrow evening from around 20:00 UTC and a few (hopefully) hours after that. This means that there will be no mail traffic at that time to and from centos.org domains. We need to move away mail from the current machine to a new machine, as our old mailserver is a bit unreliable at the moment (the hardware is showing its age). After

Hi there, I''ve read the paper on Xen live migration, and it shows some very impressive figures, like 165ms downtime on a running web server, and 50ms for a quake3 server. I installed CentOS 5 on 2 servers, each with 2x Xeon E5335 (quad-core), 2x Intel 80003ES2LAN Gb NICs. Then I installed 2 DomUs, also with CentOS 5. One NIC is connected to the LAN (on the same switch and VLAN), the

On August 4th (~9AM PDT, exact time TBD), all LLVM related mailing lists will move to a new mailing list server and will change to listname at lists.llvm.org. LLVMDev will probably change to LLVM-Dev to preserve consistency. This means a couple of things: 1) All mailing lists will be down on August 4th. We anticipated at least the full day of downtime (hopefully less if things go well). 2) SVN

Dear LLVMers, What: Potential Downtime of LLVM Web/SVN Server When: January 6, 2009 from 8:00 am Central time to 12:00 pm Central time (4 hours) Why: On January 6, 2009, some maintenance will be done on the heating/cooling system of Siebel Center (the building in which the LLVM web/SVN server is located). The cooling system will be turned off, and it's possible that temperatures may

I'm wondering if virtualization could be used as a cheap redundancy solution for situations which can tolerate a certain amount of downtime. Current recommendations is to run some kind of replication server such as DRBD. The problem here is cost if there are more than one server (or servers running on different OS) to be backed up. I'd basically need to tell my client they need to buy say

I have a large disk full of data that I'd like to upgrade to SW RAID 1 with a minimum of downtime. Taking it offline for a day or more to rsync all the files over is a non-starter. Since I've mounted SW RAID1 drives directly with "mount -t ext3 /dev/sdX" it would seem possible to flip the process around, perhaps change the partition type with fdisk or parted, and remount as

Hi, I have a 2-node replica volume running with GlusterFS 3.3.2 on Centos 6.4. I want to shut down one of the gluster servers for maintenance. Any best practice that is to be followed while turning off a server in terms of services etc. Or can I just shut down the server. ? Thanks & Regards, Bobby Jacob -------------- next part -------------- An HTML attachment was scrubbed... URL:

Where can I find documentation about manual configuration of Gluster peers/volumes? All documentation seems to be about the gluster CLI. I would prefer manual configuration to facilitate automation via scripts (e.g. Puppet/Chef). I also read in this list that it is possible to configure Raid10 via text files... I would also like to experiment with this setup. Any related documents on how to do

Hi all, I''ve been reading through the code regarding paging --> spending a lot of time in mm/*.*, as well as some of the other parts up a level or two, but I''m still unclear as to some key things. Here''s what I think I know: I think I know how a domain''s shadow page table is first allocated E.G. the hash_table is xmalloc''ed and when it is

Hello folks, I spend some time today mucking about trying to figure out how to make our documentation search a better experience. The short answer is, search kind of works now. Long answer: mkdocs creates a client side file which is used for search. RTD overrides this by referring people to Elasticsearch. However, that doesn't clear out stale entries and we're plagued with a whole lot of
