I have a blade BL860c running on a C7000 chassis, in which is connected to a NetApp, so lately I am having I/O issues, and dmesg as well as syslog.log is reporting the following:
/dev/vg01/lvol2 file system file data error in dev/block 0/55892768
Page I/O error occurred while paging to/from disk
PVlink 31 0x050200 Failed. The PV is not accessible.
My opinion is that this is a problem of some disk on the NetApp, please can you guys confirm?
It could also be connection issues with your NAS, what type ? Fiber? SCSI cable?
Or even a faulty inboard interface... but since we don't know your configuration, we cant say more...
