Hello,

 One of our XEN slave server became freezed and only a reboot could make it 
up. On checking the server's /var/log/messages, we could find the following:

================

Nov 20 18:16:46 s433 kernel: s:0: rejecting I/O to offline device

Nov 20 18:16:46 s433 kernel: sd 1:0:0:0: rejecting I/O to offline device

Nov 20 18:16:46 s433 last message repeated 85 times

Nov 20 18:16:46 s433 kernel: sd 1:0:0:0: re:0: rejecting I/O to offline device

Nov 20 18:16:46 s433 kernel: sd 1:0:0:0: rejecting I/O to offline device

==================



Can you please shed some light on this? Now the server is working fine with 
out any issues. But we need to know whether this is caused due to any h\w 
issues such as RAID or is this any know bug in XEN. The server is having the 
OS "CentOS 5.2 x86_64".

Thanks,
CPTECH
