Nope...not urgent for anyone but you. Don't flag it as so, and if you'd really like some 'quick urgent help', provide information about your system. You don't say anything about what version/distro of Linux you're running, what kind of hardware, if you're using LVM's, SAN, local disk, or anything else. Just a generic message.

You have a disk going bad, or an LVM is in a bad state. Google points to alot of info.

Have a look around Google next for (say...): "raid Linux degraded."

For instance:
How to fix a degraded Linux software Raid-1 mirror http://krul.nu/2007/06/08/fixing-a-d...raid-1-mirror/

I don't intend this as "RTFM" ... I simply don't want to repeat what has already been said. At this point, you know that one of the devices in the RAID is either not-working or is not in-sync with the others. Immediate intervention is needed, and that's what the e-mail was for.

There is no "cookbook solution" for how to proceed: first, you have to figure out what's actually wrong. (And you might have to figure out how to figure it out.)
