[Linux-cluster] Buffer I/O error on dev cciss c0d0p9, lost pagewrite due to io error

Thu Mar 2 12:47:36 UTC 2006

Hi 

Whenever I write some large file on SAN Logical Volume, after writing some
data it gives me error in /var/log/message.

as follows:

          Feb 28 11:08:53 s1_new kernel: cciss: cmd f7400000 timedout

          Feb 28 11:08:54 s1_new kernel: cciss: cmd f7436fb4 timedout

          Feb 28 11:08:54 s1_new kernel: printk: 232 messages suppressed.

          Feb 28 11:08:54 s1_new kernel: Buffer I/O error on device
cciss/c0d0p9, logical block 2162845

          Feb 28 11:08:54 s1_new kernel: lost page write due to I/O error on
cciss/c0d0p9

Also it is noticed that when started with clean reboot of systems servers
including SAN device)

I/O on SAN works very fast for the first few seconds then it starts timeout
and page lost errors

This is HP MSA 500G2 connected with HP DL 360 G4 , RHEL 4 ES U1(2.6.9-11)
