Hi pals

Got this problem and I am just seeking help here in case someone has a quick
solution that can get us out of the problem.

We have a mysql database that run on xfs. About noon today, the database
died and a quick digging pointed to an issue with the file system. We have
tried file system check, but the restarting the database causes the problem
to reappear again. Now, I am not sure whether this is a bug in xfs,  dmks or
data, and thats where I am seeking some assistance.

Here is the tech details
- Linux database 2.6.18-92.1.10.el5 #1 SMP Tue Aug 5 07:42:41 EDT 2008
x86_64 x86_64 x86_64 GNU/Linux
- kmod-xfs-0.4-1.2.6.18_92.1.10.el5
- xfsprogs-2.9.4-1.el5.centos

Below are the logs. What would the most advisable way to go about it if it
were in you in facing this problem:

Thannks for any assistance:

Regards,

William
