Re: [Xen-users] repeated DomU volume corruption

[Robert Rust <rjrbytes@xxxxxxxxx>]

I'm not sure there's been a significant improvement. I just did package updates and 4 of my 7 VMs ended up exhibiting this problem. One may have already been in that state when I started (hard to tell), a second appeared to have it happen mid-shutdown, a third had it happen after it completed downloading the package updates but hadn't installed them yet, and the 4th I'm not certain of. All 4 had the nobarrier option in their fstab:

/dev/xvda2 / ext4 nobarrier,noatime,nodiratime,errors=remount-ro 0 1

Further thoughts?

I had an issue similar in nature, which manifested as a missing partition table after a domU reboot, mounting the xvda{x} partitions with the "nobarrier" mount option resolved it. The issue was observed on xfs and ext4 filesystems.

Hope this helps.

Okay. I've added the nobarrier option to all my DomUs ... we'll see how that goes. Here's hoping it's that simple ...
