Hosts 3, 5, and 6 will be upgraded from 2.4 to the 2.6 kernel with the performance patches. Host's 14, 19, and 25 are being rebooted to bring the RAID array back into sync, and will also get the 2.6 host kernel with the SYSEMU performance patches.

Reboot Schedule

Thu, June 17th, 2004 22:00 EDT (-4 GMT):
host3, host5, host6, host14, host19, host25

Reboot Details

All Linodes will be shutdown properly, the host will be rebooted, and then your Linode will be automatically rebooted using the last used config profile. You do not need to issue reboots. Actual down-time should be between 15-30 minutes.

Please allow a one to two hour window for the reboot of your host to occur.

If this affects you, you'll be getting an email from me shortly.

Status and details will be posted on this thread.

Thanks,
-Chris

Keep in mind this is only a kernel upgrade on the host themselves. Linodes will continue to run whatever kernel you've been running, although to get the performance improvement of the SYSEMU patches, you need to keep "Latest 2.4" kernel selected in your configuration profile.

Hi Caker,

Have you sent out the emails yet, as if you have I havent had one.

Also it would be nice to have a bit more notice next time.

Jun 15 23:04:50 nova sendmail[4274]: i5G31hYi003996: to=<adam.gent@(snip)>, delay=00:01:22, xdelay=00:00:01, mailer=esmtp, pri=1050510, relay=scanner.(snip).(snip) [(snip)], dsn=2.0.0, stat=Sent (Ok: queued as 4F24A2A870)

Thanks. I'll keep that in mind. However, with the RAID going out of sync, I didn't want to take any chances. I figured 48 hours was a good minimum notice in this case.

-Chris

Lemmie guess, you're going to wait for a day or two for the 2.6.7 kernel to get the floating point bug.

No hurry here.

Hi Caker,

I did get the email in the end, it was stuck in a mail queue due to the pop server been offline.

48 hours notice is ok, when I looked at the dates I though it was less than 24 hours, must have been half a sleep at the time.

Why does the raid keep going out of sync, is it hardware or software?

Adam

Software RAID1. AFAIK, it's a bug in the Linux IDE drivers. It's happened before under 2.4 and on the 2.6 hosts. There's been some discussion about it on LKML, but nothing decisive. Using smartctl (part of smartmontools, a really, really useful set of utilities), the drives don't report any errors, so I'm confident it's not device related...

Looks like host25 has a bad drive, so the RAID array is running only on the one disk for now. I'll let you know the scheduled downtime for a replacement in the coming week or so...

Host25 upgrade complete

i'm curious about this, but it's not urgent, i hope it's not a stupid question:

at 4:35GMT (23:35 -5, 30 mins ago) i checked my linode on host14, and there was no mail, web or ping. the page at members.linode.com claimed it was running so ...

i ssh'd to host14.linode.com to see the console, and immediately the 'machine' started to boot (maybe a little slowly) and came up absolutely fine, but it was obviously my sshing to the console that provoked that (?).

it wasn't an illusion because mail and web services resumed in sync with the console messages. the machine normally reboots fine.
