[gentoo-user] / becomes read only
List members - I have a Gentoo install running inside of a vmware ESX server virtual machine. I am having a very strange issue though. Every few days the root filesystem will become read only and the only way that I can fix it is to reboot or power down the virual machine. Does anyone have any ideas as to what might be causing this? I have searched through the logs and the only errors tha I see regarding my root device (/dev/sda3) seem to be coming from the FSCK that is done on reboot of the sever. Any suggestions would be greatly appreciated. Thanks, James -- gentoo-user@gentoo.org mailing list

A disk timeout error could cause a filesystem to be remounted read-only. And if /var is on the same disk, you wouldn't necessarily see the errors (since, after all, it is now read-only!). I would start by making /var a separate filesystem if you haven't already. Heck, put it on a different virtual disk if you have to... -Richard -- gentoo-user@gentoo.org mailing list

I have moved /var to a separate virtual disk. Hopefully this will give me some clue as to why the root filesystem keeps becoming read only. If it does turnout to be a disk timeout do you have any suggestions as how to fix the problem? Thanks, James -- gentoo-user@gentoo.org mailing list

I also had an similar problem (on an physical machine) which I couldn't reproduce. It seemed that the disk itself became ro for some reason. Unmounting and mouting again didnt help. It told me the medium was ro, and so the fs got mounted ro, too. Maybe your logfiles can show anythin strange happened on the disk (may an temporary problem on the host disk). BTW: I've got some usermode-linux jail somewhere in the net, which randomly gets an ro root fs - I always have to ask the provider to fix it (no idea what he actually does). A few days ago, the problem occoured again, and my provider told me there was an hw problem and he has to change the broken hw. Maybe its the same kind of problem ? cu -- - Enrico Weigelt== metux IT service - http://www.metux.de/ - Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ - -- gentoo-user@gentoo.org mailing list

Well, it is a very big if at this point. It is equally possible that you have an bad block on the drive that causes an IO error, or a corrupted filesystem block that confuses the filesystem driver, or... Hopefully a log will get written to give us more info. If linux were running on the bare metal, I could probably make some suggestions on how to avoid a timeout appearing in the guest os (schedulers, sysctl settings, etc); however I know nothing about ESX server and what is available there for tuning. You might post the problem to the vmware ESX forum and see what they have to say. The VMWare forums usually provide top-notch support for these kind of things... -Richard -- gentoo-user@gentoo.org mailing list
