lvm problems

[jordank]

Hello

I am running a rhel 6.1 server that is configured with lvm partitions. I am having problems with this becoming corrupted and causing the server to stop functioning. When I look at the main terminal it tells me that its root filesystem has become read only and I am not able to do anything.

I have been able to fix this problem by loading backtrack, installing lvm toosl and running fsck to fix the corrupted filesystem. My problem is that this has happened twice on this server and it has also happened on one of my debian servers. Does anybody have any ideas on preventing this from happening or figuring out how it happend in the first place?

Thanks
Jordan

Filesystems suddenly going readonly is a indicator, that the disc is broken.
Do you see any io related errors in dmesg
what is the s.m.a.r.t. status
or -if applicable- what does the raidcontroller have to say about the discs?

I just looked at dmesg and there was nothing there that indicated problems, at least after I fixed the corruption and rebooted. This is a virtual server and does not have its own hard drive. I am using a rhel5 server in a raid 6 that holds all of my vm's. None of the other vm's are having corruption issues like this. All the other vm's are running Windows server or another form of Linux not using lvm. The other debian box that did the same thing yesterday was a phisical machine and I might be able to run a hard drive and smart test on it. Any other thoughts or things that I could try?
