[opensuse] Volume mount going mad..
I have this 11.0 server running as a VMware guest. The SUSE system runs only a MySQL database, and of course the most basic processes needed. Every now and then the MySQL server stops answering, and when I check the server, the mounted file system has turned read-only. The file system is a reiserfs 3, and one volume keeps all of the system in one partition. After reboot, reiserfsck cannot fix the file system without going to a complete 'rebuild-tree'. I havenn't been able to find any traces in any log to why it does this, so I'm puzzled and any ideas on this would be great.

Hey Anders,

Which kernel version is running in the guest? And this is a vmware esx, by any chance? greets thomy -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hm, ok. I had the same problem you describe with a vmware esx, but maybe this can help you: the problem was the kernel scsi-driver in the guest (I assume your guest has also an msi-logic scsi adapter). When the host disk-system was on high traffic, the underlying guest couldn't write his journaling entries to disk in the right amount of time. Before writing nonsense to disk, the guest system decided to go read-only. Solution was to install a top-notch kernel. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I doesn't sound all that unlikely.. The host has been quite busy "disk-wise" at times... I'll keep an eye on that, maybe I can see a connection next time it happens. Thanks a lot, at least I have something to look at now.. ;-) Anders. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I might have what appears to be a related problem. I have an external disk, connected via usb (which uses the scsi subsystem), on this 11.0 machine, formatted as reiserfs, and it develops errors that force it to become read-only, and requires a long session of reiserfsck --rebuildtree.

Thanks for the feedback.. In fact, no I haven't filed any bug to this yet... Darn, I don't have a clue on what's happening on my system since I don't get anything whatsoever in the log files.. But I'll try to keep a closer look and see if I can trace some "external" events triggering this, like the host system being really active on the disk system.. Which I somehow doubt a little since it's a RAID-10 on SATA-300 with a 512MB RAID controller cache, but for now it's my only clue.

Thinking of it, which SCSI emulation would you guess performs better under Linux? The LSI-Logic or the BusLogic? I haven't been experimenting with them at all, I've just gone along with the default LSI when setting up VMs. Anders. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Try increasing the kernel log verbosity. File "/etc/sysconfig/syslog", variable "KERNEL_LOGLEVEL=7". You have to do an "rcsyslog restart" afterwards. - -- Cheers, Carlos E.
